Power light on but nothing else

Question: Power light on but nothing else

I have an E-machines T2642 2.6 Ghz Intel Celeron processor, RAM 256mb PC2100 DDR, ATA/IDE hard drive. Here is what has happened. We had an electrical storm but the computer was plugged into an APC battery backup. The computer stopped working. The power light would start blinking on and off but the computer would not boot up and there was no whirring of fans or the hard drive. Eventually the light would not even come on. I thought it may be the hard drive so I bought another one and nothing changed except the power light will stay on when the computer is plugged in. So I thought it may be the power supply. Bought it and replaced it. Nothing different. So now I am toying with replacing the motherboard. But I have never done this and am wondering if it could be something different and if I may be getting in over my head. Also considering that a new desktop costs less than $500 and I don't do a lot of heavy processing so I do not need high end graphics cards or anything like that. The money I have spent so far is $50 for the hard drive and $20 for a power supply. Any help would be appreciated.

Preferred Solution: Power light on but nothing else

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

Answer: Power light on but nothing else

eMachines have notoriously poor power supplies that often take out a motherboard or other components when they fail. Without replacing things there is little else to do with those symptoms. Luckily that hard drive can be used in another machine, and a $20 power supply is questionable at best. If you get another motherboard, then your restore CD may not work, etc.I would go for another brand, but that's just me.

dell xps m2010 wont start up ,blue power light and bluetooth light stay on,i have been searching posts in other forums as well as this one and i thought i`d narrowed it down to the graphics card,i was right to an effect,my approach was to take the xps apart following dells website documents,while i had the top (dvd drive) off ,i noticed that the graphics card screws were really loose (this was my first job)...i tightened these.The top(dvd drive ) i re-connected ,but propped it up at an angle so i could still see motherboard and parts,(warning!be carefull!!)electric!! ...attached power cable and pressed power button after half a dozen times pressing this it came to life.I noticed my fans were working and thought this might not be my motherboard after all ,no overheating happening...then it froze on windows xp ??it was a start !another 6 to ten times pressing power button it worked again this time not freezing.went into bluetooth with usb mouse and paired keyboard ,made system restore point and restarted .It took maybe 4 times with it being glitchy(freezing ..not powering up) ,but when it does load xp without freezing try restarting windows xp and then it eventually finds its feet!!!my xps 2010 is running ok now.jimb

My laptop was working fine yesterday, charging and powering on an off normally. It updated without my telling it to. When it was complete (since it said don't turn computer off until finished) I either just shut the lid or I shut it down when it was done. This morning when I wake up and try to turn it on it won't power up. Then I noticed that the power button was blinking, like it is in sleep mode, tried pressing 10 times then holding down power button for 30-60 seconds and still nothing. Next I saw that although the power is plugged in the battery light won't come on. I don't know if it is charging (it could be dead). I tried a bunch of different outlets and that isn't the issue. I also listened to the computer and there is a very soft high pichted noise that dissapears if you unplug it, and that when you hit the power button and it starts blinking, the sounds changes fom high to lower pitch and back again over and over. But no other sounds or fans kicking on or drive spinning. I am pretty sure it isn't the power cord but have no way of checking. And I can't remove the battery without voiding the warrenty. Anyone have any advice, besides calling to have Lenovo send me a box to send it back to Lenovo since it is only 4 months old and still under warrenty?

Answer:Lenovo Edge 15 laptop 80K9 battery light won't come on, power light blinks

Suggest you eliminate problem 1. Do you have spare power supply unit? Worth trying that first. Your battery may be in sleep mode and won't wake up as battery is drained and hence needs charging. 2. You can go to local retailer and suspect a good one (John Lewis) will let you charge it for 30 mins. Ideally go back to person you bought it from. 3. Once you are in use restore to go back to last working point. I have to telll you the support from Lenovo and Microsoft was very very very disappointing. I tried to even return the PC and swop for HP as mine is only 2 months old. However, the answer was send back to Lenovo. Hope you find a way to get it charged

Hi. Tonight I had a problem with my laptop. It was in sleeping mode, and when I open the lid there were no mouse function and no touch screen function. So the only thing I could do was to press the power button for 3 seconds to turn it off, but it didn't completely, because the screen turn off, but the power button light is blinking just like when it is on sleep mode, and I'm not sure if the hard drive light was on, off or blinking before this, but now is blinking. I press the power button and nothing happen, I press it for 3 seconds and nothing happen. I even did the HDMI connection to another monitor, but both monitors don't show anything, not even recognize that something is connected to the HDMI port in the new monitor. There is no sound, nothing, just the 2 blinking lights. What should I do? Thanks PS: I'm not sure if it's Windows 10 32-bit or 64-bit. It was upgraded from Windows 8

I will turn it on and after a minute or two the monitor goes to power save mode and the hard disk light goes from off/blinking to solid on and the power light stays on.

I have reinstalled the operating system and i thought that fixed it. I had SP 1 i installed all of my updates and SP2 and it starting to do it again (it will do it in SP1 but not nearly as often or when i run a flash heavy program: PSP Video or even the Scion website).

It will not do it at all in BIOS as i did every test on the diagnostics page for my hard drive (all pass) though if it turns off it usually turns on and runs dskchk and it wont stay on for that

In safe mode it is also fine it will not turn off once

I dont know what i did last as it was fine then i was gone for a month and I had it unplugged etc., came back hooked it up and it started doing it after a little while

I have taken a can of air to every inch, switched the Flat cord going to the HDD from the Motherboard.

All fans run fine

Thats all i can think of right now ask me anything else you need to know

I'll give this forum a couple of days/a week maybe then i'll take it to a local shop to diagnose it

Much thanks to anyone who has any idea's

Hello,
Was experiencing general issues with my windows profile after windows updates last patch Tuesday so I initiated a system restore and let it run today.  After completion laptop turned off (instead of rebooting?)

Pressing the power button: Power button turns white (on) for ~30 seconds, then laptop turns off (indicated by power button light)
no fans
no screen (back-light or otherwise)
no POST codes - beep codes or light codes.  
no other visible activity

During that period nothing else happens, unless I press the power button again. If I do this
The fans spin up momentarily
The system then powers off (as indicated by the white power light)


I've tried:

Disconnect power/battery and hold power button (60 seconds)
Power system on with just battery
Power system on with just wall power
Remove mSATA HD and repeat the above
Disconnect video connector and repeat above
Remove mPCI WiFi module and repeat above
Completely disassemble and remove CMOS battery (tested at 3.1 VDC) for 60 seconds, reassemble and repeat above

All with no change in behavior

I am able to get a light code 2 Amber / 3 White if I remove the RAM module (as expected)
D + PWR diagnostics cycle successfully through a range of colors then nothing

Laptop is 2 months out of warranty.  Any help debugging the issue is appreciated!

Hi Wacky78900,
 
Welcome to Lenovo Community Forums!
 
I?m sorry to hear that your Y500 Laptop is not turning ON after playing game and turning OFF manually, I suggest you to perform the Flee-Power and check the issue. Below are the steps to check and resolve the issue:
 

Remove the battery and any other peripheral device connected to the computer.
Hold the power button for 10-15 seconds and then connect only the AC Adapter and try to turn ON the computer.

If the issue persists even after performing the Flee-Power and as the computer is in warranty, I would Strongly Suggest Calling Technical Support for Assistance. Click here to open a link where you can select the country and get the exact contact support number. I?m sure they will be a great help.
 
Do post us back for further queries.
 
Best Regards

Shiva Kumar

Hello! I have been having this problem for about a week now, ever since I set my old computer back up in my room. The problem started when I left my computer alone for a while when I went out (the computer was working fine and I had just finished transfering pictures to my computer from my camera). I came back and the power light on the front if the case was on, but the battery light was off. The monitor had also gone into sleep mode. I turned off the computer since I knew whatever I was going had already been saved and exited out of, unplugged everything (including the monitor and PC/Monitor cable) and plugged it back in and turned them on. The monitor goes straight to power saving mode (sleep mode). The PC is definitely receiving power, the keyboard's caps and num lock keys flash, the wireless mouse's light flashes, the pc fans turn on, and both of the power and battery lights turn on. But, after a second, the battery light turns off, and the only light I can see through it is the power indicator's light bleeding through. The strange thing is, I've been able to get it to work before, about 2 times actually. Both of those successful boots happened either when I ignored the thing for so long or left it unplugged over night, but had already forgot it didn't work last time. But it did those times. So I tried to leave it unplugged all last night. Just woke up, and... still nothing. I really need to to get those pictures to my mom, so if someone could ple... Read more

This just started happening recently. The power indicator light (near the power plug) does not turn on and Windows does not recognize when the adapter is plugged in; the power icon and cusomized power saving "on battery" behavior reflect that. HOWEVER, the battery does charge. The "lightning bolt" charging light on the front between HDD and system power lights comes on and the battery recharges if not at 100%. Any thoughts on how to troubleshoot this? Is it more likely a Windows or hardware problem? The BIOS does not have the power adapter test mentioned here, and I could not find the software download for the Smart Adapter functionality (this laptop was installed with clean, non-OEM OS, so any OEM software had to be added manually). Thanks in advance,Kyle

alright, I just got this inspiron 6000 from my sister that didnt work. she said nothing would happen at all. well it turned out the power light would go on, caps lock light blink for a few seconds and it would turn off. somehow the memory wasnt in the slot very well. bam, got it working, dumped all her pics and crap to a external hdd, and wanted to wipe it all out and start over. she is sending me a xp disc, but for now I just figured Id go back to 2k cuz I have that disc and when I get the disc go back to xp.

anyways, I couldnt figure out how to format the drive, because obviously xp was running off of it. anyways, I kept trying all the del - f2 - f8 - f12 to get a dos prompt before windos would load but I couldnt. so I figured Id just put the 2k disc in because I thought I remember that it formats it right before it installs. but it asked me where to install and the disk was partitioned and I wanted one drive letter so I cancelled the install, before it was actually installing though, said f3 to quit and I hit f3. now when I try to power it up, the power light comes on, the hdd light comes on for maybe 1-2 seconds max, then the cd drive light comes on and it spins up, then stops, and the screen just stays black, never did anything either. just black the whole time.

Answer:Windows XP, power light, hdd light for 1 sec, black screen

oh, also, i did try and search and most I found were a black screen after the self test or the windows logo, not right away.

also, dont think it matters, but when the lights go out, it is at the point where hitting the power button again, the computer instantly turns off.

also, just checked, and its nothing to do with the lcd. I just hooked up my monitor, and my monitor tells me when there is no signal, and it just stayed black, then when it was unplugged from the laptop that is when it said no signal.

Why would a computer take hours and days before a display? When the system is turn on very ofter the power light keeps blinking and the harddrive light is on but nothing shows on the monitor for hours or days and may not at all. Powering off and re-powering rarely helps it just have to be left alone and comes on whenever if ever.. Thanks for help

Answer:The power light keeps blinking and the harddrive light is on

Try a new signal cable from PC to monitor.If no change, try a new graphics card.If still no change, test the hard drive with "Seagate SeaTools for DOS".Click the "Download" tab here: http://www.seagate.com/support/down...The download is an ISO file, so you'll also need to install "IMGBurn" from here:http://filehippo.com/download_imgburn/Use IMGBurn to create a CD from the ISO file, then boot your faulty computer from it. The testing program will open. Select the hard drive and test it. If it fails the test you need to replace the hard drive.If hard drive passes the test it's okay, so test the RAM modules with "Memtest86" which is also an ISO file, so you need to create a CD from that too:http://www.memtest.org/

I have a Dell Dimension E510 that as of yesterday, won't power up anymore. The power light blinks orange and the computer does nothing when the power button is pushed or held in. It's about 16 months old and is out of warranty, so I'm trying to diagnose the problem myself.

I did some searching on the internet and found that this seems to be a common issue on these Dells, sort of a long term infant mortality issue. The most common causes seem to be a bad PSU, MOBO or a shorted USB input.

I've done some diagnostic checks/testing so far and am now stuck. Here's what I know.

- The USB ports don't appear to be shorted. I also disconnected the connector for the USB (which includes the power switch :banghead and it doesn't change any of the results that follow.
- I removed the power supply and jumped Power On (terminal 14, green wire) of the main ATX connector to ground. The fan comes on and all voltages (3.3, 5 and 12v)check out, including around 5.35v at Power Good (terminal 8, gray wire).
- With the power supply back in and everything connected, there is only 3.3mv at Power Good. As I understand it, this would normaly point to a bad power supply; however, all of the voltages check out when the unit is disconnected from everything.

Is is still possible that the power supply is bad, or is it more likely (or definitely) that the MOBO is the culprit.

Any help, including suggestions for additional testing is greatly appreciated.

Hi,
I picked up this Alienware 5700 off ebay to hopefully refurbish for my son but I'm new at this and still learning and so this thing has me baffled. The laptop is in pristine condition but shows no signs of life. When I plug in the power supply the green light on the power supply goes from solid green to blinking rapidly to the point you can barely see it. To me that would mean a short somewhere right ? If so where ? Has anyone else ever had experience with something like this ? I just don't want to go buying a new battery for a laptop that maybe fried already. Any help would be greatly appreciated.
 

Answer:No power, no lights but green light on power supply blinks rapidly

Remove the laptops battery and try the AC power only. If the green light does the same, it still could only be a bad AC adapter, or at worst, a shorted laptop motherboard

My Inspiron 15R N5110 won't come on. I've tried both battery and 2 different ac adapters. I've removed the battery, unplugged it, and held the power button for 30 seconds to discharge the system, but it still won't come on.
I took the laptop apart and everything looks alright, but the DC jack was slightly brown on top so I replaced the DC jack board. It still won't work.
I made sure the connections are tight (the DC jack and other USB board) by screwing them down. The only thing that happens that shows any life is when the battery is in. The power button, power indicator light in front, and the little "gears" light blink white for just a moment, then off, about every 5 seconds.

Any ideas? If I have to replace the motherboard, what is the difference between 0G8RW1 and 0VVN1W? I'm not worried about the product key not validating - may even put Windows 8 on it.
Thanks!

My Dell Inspiron 1545 has been sitting for a while, and when I went to plug it it and try to use it, it would not turn on. All I got is a pulsing power light like when it's in sleep.
I recently replaced the battery as well as the charger, because the original battery was shot and the charger was in horrible shape. I also replaced the power jack a while back because the pins inside were bent and the laptop got no power.
I had successfully used the laptop for a while after replacing these parts, but now it won't turn on. Whether I'm on battery, AC power, or both, it only flashes/pulses when I press the power button. If I hold the power button, it will shut off.
What's wrong here? I have checked and re-seated both memory modules, also testing both slots and nothing changed.

Answer:Inspiron 1545 Won't Power On, Pulsing Power Light Like When In Sleep Mode

Hi CARCRAZY98,
Thank you for the update.
Well, when you power on the system, if you hear the fan spinning and the HDD turning on, connect an external monitor and check if there is any display.
Reseat the cmos battery and check when possible. Since the system draws power from the adapter, at this point, I would not suspect the adapter. Also, remove the memory modules and disconnect the HDD and check if the system comes on and beeps - indicating a missing HDD / memory.
As advised in my previous post, if nothing works and the indications do not change, I would suspect the motherboard.
Let us know if you have any other queries.

Unplug the system, remove or disconnect the battery, and hold the power button for 30 sec.  Remove the base cover and memory modules;  reinstall both.
Try powering up on AC only - if it will but won't with the battery, the battery is faulty.
If it still won't power up  after the foregoing, the mainboard is bad.

So my N21 chromebook seems to have a AC connector issue, most likely on the chromebook itself. as seen in the photo and video, the connector seems very loose, and no light comes on when plugged. it doesnt "click" when plugging in like other laptops, it just "slides" in and slides out very easily https://goo.gl/photos/5jujCxawE3AubxvP7 i tested the AC power adapter (official) with a multimeter while it is plugged into outlet, and it shows 20V which means it SHOULD work ok.  but obviously does not when plugged in, I feel it's very loose and when i looked into replacement AC adapters there seems to be TWO different connector sizes:  http://www.ebay.com/itm/Original-OEM-Lenovo-Chromebook-N21-45W-20V-2-25A-3mm-AC-Adapter-ADLX45DLC3A-...  <-- 3mm X 1mm http://www.ebay.com/itm/Lenovo-Chromebook-N21-Notebook-20V-2-25A-45W-Power-AC-Adapter-Charger-Cable-... <--- 4mm x 1.7mm What I have is the 3mm X 1mm , and i'm thinking it might be NOT charging because it is too loose and not touching. So will buying the 4mm X 1.7mm work as it is "tighter"?  But why is the official one loose?

I would presume that the power adapter that came with your Chromeboosk is the correct one, which should be part number 5A10H70353 (see link below).      If it was working fine before and just started acting up, it is probably a problem with the jack itself, and not the size of the power plug.     If it is under warranty it would be covered, but if not under warranty, the part needed to fix it is part number 5C10H70350  $12.95 USD and is available from the link below.    If the system is not under warranty, instructions on how to replace the DC-in cable begin on the bottom of page 35 in the Lenovo Cromebook N21 Hardware Maintenance Manual and requires some disassembling of your Chromebootk, but if not comfortable in doing it yourself, it should only take a good laptop tech about an hour to replace. Note:   Before buying an parts, I would recommend that you go to http://pcsupport.lenovo.com, click on the Detect My Serial Number, and then click on the Parts & Accessories link to ensure that the parts you purchase match the exact Machine Type-Model or Machine Type of your system..    5C10H70350 Lenovo Ct Cables Internalhttps://lenovo.encompass.com/item/10633467/Lenovo/5C10H70350/Ct_Cables_Internal 5A10H70353 Lenovo Ad Ac Adaptershttps://lenovo.encompass.com/item/10638409/Lenovo/5A10H70353/Ad_Ac_Adapters Hardware Maintenance Manual Le...

i have tried to power it up with power ac plugged in and without. on/off power button flashes white.
battery is inside "sealed" and may be difficult to access.
ran fine yesterday, shut down with 20% battery life.

if the ac plug is unplugged then i can get the led to turn off but once pushed, it ony flashes. no results

warranty is expired.
unit manufactured april 23 2015

i currently have it plugged in but no flashing light as i have not pushed the power button. im hoping that it will take a charge or correct itself with time.

what do you suggest? thank you

Answer:i have a lenovo edge 15 model80k9. led power light is blinking but computer will not repond. no power up . the battery is "s

Try the following...

1. Take out (or take it off) the charger.
2. Next take out the battery
3. Now hold down power button for 20 seconds and then rinsert battery.
4. Now put it on the charger again

NOTE: Make sure charger is plugged into the main power supply (not an extension cord, surge protector, etc.)

Sometimes, when the device is not plugged in directly, it doesn't get the power it needs. Holding the power button, while you restart it, clears out the temporary ram (no it won't delete anything you have saved) and will give the device access to the ram it needs.

My computer was down when I came back from lunch and could not get it to come back on.  If I hold the power button down for about 7 seconds it blinks orange but there is not noise from the fan coming on or post beep.  Also the green light on the back is not on either. All of the other equipment sharing the same power strip come on but not the desktop so it is not the power strip.  I also tried to set it up in another office on a completely different circuit and still does the same thing. What should I try next?

Answer:OptiPlex 790 Wont power on power light blinks amber

Which form factor, desktop, mini-tower, small form, ultra-small form?
From the (desktop) manual: Blinking amber light indicates a problem with the system board.
Are any of the 4 diagnostic LEDs on when it won't boot? ,They're on the front of the PC next to the power button. Look up error codes in the manual.
Possible power supply failure if the green light is off on the back. Can you try a different power cord? What happens if you push the power supply diagnostic button on back of PC next to that (green) power light?

I have a HP Mini 210 - 1030NR which won't turn on. There is no lights anywhere. Nothing happens when i press the power button.
I took out the hard drive and it works on my desktop. I took out the ram and tried to boot it up but nothing.

I am assuming it's probably a dead motherboard.

How can i test to see if the motherboard using a multi-meter?
I thought it was where you plug in the power adapter but I already tested some parts and i got 19V there, so i know it's not that.

I also tested where the battery is charged and it got .049v, so i know its working
But i tested the little white connector where the heatsink fan is going, but i didn't get any volts there, isnt there supposed to be some volts there?


I'm not sure whats wrong, anyone have any experience with power?

I have a Sony VGC-RB42G computer. I recently moved my computer, cleaned off all the dust, and when I plugged everything back in, it won't power up. The light on the power supply blinks green, inside the motherboard also has a green light that blinks as well. It has a ticking sound too, but I am not sure if it is coming from the power supply or the motherboard. Any idea what could be wrong.

FYI, I have already unplugged everything from the power supply, pulled out the ram, checked the battery, and put everything back together and still no change. One thing I thought was strange was after I unplugged everything, I pulled the power into the power supply again and this time the green light came on but did not blink. It stayed solid.

Hi everyone,

My pc just shut down this morning. I had a spare power pack- brand new and I fitted that.

Windows ran perfectly for 10 minutes then the same thing happened again!

I noticed on both occasions, that even after I had removed the extenal power lead, the green power 'on' light kept on flashing on/off.

I have never noticed that before when a power pack 'blew'.

Does anyone think I was unlucky with a 'duff' replacement power pack?

Is the flashing power light indicative of some oother fault?

Any and all help welcome. PLEASE!

Many thanks.

Both batteries 9 cell and 6 cell had full charge, tried my other Lenovo charger... no go. A surge couldn't have happened as the laptop is plugged into same strip as my other lenovo laptop is and that one is working fine.

Hi jack61 , 
 
 
Greetings. 
 
We now know, power drain failed. No LED error codes , No beep codes
No activity lights even with battery charging led.
Not turning on even with known good charged batteries. 
No power even with known good ac adapter.
 
What we can try:
Try plugging it directly on the wall and press novo key (number 1 page 7) to turn it on instead. 
Check if the power port shows any signs of burnt / damage / looseness . 
Press Novo key using a charged battery. 
Remove battery, harddrive , memory and other accessories and plug directly with a known working adapter and or with a charged battery ( it should at least beep). 
 
If all fails , you can have it checked for the motherboard issue with a technician (checking on the internals /cleaning or reseating parts connected to the board / applying thermal paste (for processor isolation) / checking on dc in board and port).
 
You can check for your warranty here and call in tech support for service.

I have an Optiplex 390 (actually 3 with similar behavior...).
PC would not power on. I did the power test and determine the Mobo was the issue.
I replaced the Mobo with a new one. Still can't power from front power button, but if I go at the back to the power supply 'power test button' and press on it the full PC comes on with all fans everything, but front power button is amber. And I get nothing on display, fans stay full speed. I can turn off, by pressing the from power button for a few seconds.
I tried using the CPU from another of the 3 PCs that had similar power issues and pointed to Mobo.
I reconnected all cables, tried different RAM modules, different video card, nothing makes a difference.
Not sure where to look now.

Answer:Optiplex 390 Amber power light, but all power looks good

Assuming that you replaced the motherboard then it likely is the power supply has had it you'll need to buy a new one.

As you did not mention any message or display on the screen, I would use this tutorial for a step by step diagnostic.  It also helps to remove the side panel, and visually watch the CPU and rear case fan movement(s).  As you press the power button, pay attention to the fans. Also does the Power Supply LED stay ON? Or did it go OUT when you pressed the power button?

Just didn't switched on one day. Any ideas??
Cheers

Answer:Satellite L300 will not power on - no light on after power plugged in

Hi

No of the available LED are on?
Hmm? for me it sounds like serious hardware issue; if you are sure that AC adaptor and battery are ok, then there must be a problem with motherboard.
Maybe power supply electronic issue? who knows? the part needs to be checked by an ASP technician in order to get more details about the fault?

So I recommend doing this if you want to fix this notebook?.

I first logged out of my computer and came back and I noticed an orange light on the power button. I shut it of and turn it back on about two times with the same results of an orange light. I then shut of the the extension that houses 10 plugs. When I turned on the extension I turned on the computer the power button didn't give off a blue light or orange light. The VGA cable, mouse, keyboard, Ethernet cable are all plugged in. I later removed all the connects to the computer gave it a minute and plugged it all back in. There is a solid green light on the back under the power cable. The fans turn on there is noise coming from inside the computer a soft humming and light fan from the back of the computer. But the power button will not turn on. The monitor light is orange and says "No Input signal Input 2,Go to Power Save." When I switch to input 1 it reads "Cable Disconnected Go to Power Save." What internal issue could this be?

I have a T60P that's increasingly getting worse - to the point that I can't get it to turn on now. The product ID is 2613CTO I've used known good power supplies, but don't have a way to test the battery. If I plug in the power supply with the battery plugged in I get no lights.  And it won't turn on. If I remove the battery I still get no lights. With the battery still removed I can plug in the power supply and get a momentary battery light and the power light stays on. If I hit the power button in this state the power light  goes out and does not come back on until I remove and reinsert the power cord. With the power light on I can insert the battery, but both lights will go off if I hit the power button. I can leave it for hours with the power and battery lights on, but when I hit the power button both lights go off. So this doesn't sound like any sort of fuse issue, it's not the AC power supply or the battery - it should run without the battery. That leaves some sort of internal power problem.  Is there a power board that can be replace or is this circuitry on the motherboard?

Answer:T60P power light goes out when I hit power switch

Welcome to the forum!
 
Try this old trick:
 
Remove the battery, hard and media drives. Unplug the AC adapter.
 
Press the "power" button ten times in a row holding it down for 10 seconds each time and 30 seconds the last time around.
 
Plug the AC adapter - but nothing else - back in and try to power on.
 
Should this fail, your T60p most likely needs a new motherboard.
 
Good luck.

When turning the PC on the PC on light will ight up, but when i press the button to turn it on nothing happens... I'm sure this may have an effect on it, so let me give you the history of the computer. I was installing a USB card reader, and when i plugged it in the computer shut down and shorted out (i suppose) and then it actually smelt like something was burning.. Am i screwed? or is there an easy fix to this?
 

Answer:PC gets power light to light up, but nothing

Hello there. It's definately not good when you smell something burning.

I'm assuming all you did was plug the USB connector of the card reader into a USB port on the back, correct? Your case was not open or anything?

I am venturing a guess that either there was debris in the USB port when you plugged it in, or your computer was not properly grounded, or something happened to the power supply.

Your next step would be to determine what device has failed. Turn off your computer, remove the power cord to the power supply, and open the side of the case. Carefully take a look at your motherboard. Are there any visual signs of something that got fried? If you have a second computer, you may want to use that to test each part of the fried machine: the RAM, the power supply, etc.

Let us know what your situation is in better detail!

Older Dell Optiplex GX260 tower model. Okay first I extra a harddrive from an HP older system that had just recently crashed. Now I want to read that drive right? I put it in as a 2nd drive in my Dell Optiplex system, set the jumper to cable selected, go into BIOS and select my 1st drive to show it as AUTO. I hit Save changes, upon rebooting it, it gets to the end of logo display and freezes. Weird, never saw that before, I think crap maybe the IDE cable is set wrong or something. I remove the cable and molex plugs from both HDD's after the power is off and set it back to the way it was.

When I reboot I get to the end of the logo again and it freezes and I can't even get into BIOS. Very strange. Well I go back again to check my work and see it is fine with how the IDE cable is sitting and the Molex plug. Now the system won't even power on. The light to the MOBO is on but the system won't start. I undo the front panel and work to see if the cable is worn but it is not and it appears to be fine. The light to the signal will not work to go green at all.

What do you think could be most common issue of this and why? I don't have a multimeter to test the system with and I don't know if it's more than a passing problem. I have never encountered anything like this were a system worked fine then you attempted to just read a 2nd HDD and it started to cascade a bunch of problems to the system.

Any help or ideas are much appreciated, thanks.

Hi,

I have a problem with Toshiba Satellite M100, that i was hoping someone else may have seen before.

Pushing the power button only lights up the power button itself, and the power indicator on the front.

Nothing else happens.

No other indicator lights light up (unless A/C is connected, then the battery and a/c indicators light up), no mechanical sounds of any sort from within, no POST no nothing.

Then after 5 seconds or so, the power indicator and button lights go out.
Am I right to assume that it's not likely to be the PSU??

Answer:Power light

No power light ----- turn round the connector from the power light to the motherboard header, as the motherboard end. Is it in a 3 wire housing with two wires, or two individual wires? Look carefully at the description of the pins on the header - there are usually three pins for the power light, but two of them are the same (connected together on the board). You need to choose the correct two pins out of the three.

I came back to my computter after a few hours- the CPU had powered down Sori for the long gab, here it comes--

I poweredup and there is 30 seconds of HDD activity (normally 120 secs), the power button light on the front panel is blinking at me (it's usually steady), and there is no apparent bootup. My monitor stays blank except for the "On Screen Display" setup menu. Keyboard inputs have no effect, like Cntl/Alt/Del achieves nothing. No F5 or F8 to safe mode.

My digits are crossed that Disaster may not have struck, cuz:

3 hours before it auto-powered down, i had upped the display to just 1024x768 from 800x600, using the same Nvidia "optimal" refresh rate, and used it for an hour with no apparent problems.

Both my monitor, a Princeton Ultra 73e 17" CRT, and video card, a Nvidia/Jaton GeForce2 MX400 3D, claim to easily handle that measly 1024x768 rez. Everything is 3 years old, tho 'should' have many hours left.

I haven't yet swapped monitors/cpus, cuz that is going to be a lousy dismemberment of my wall cabinets. Anyone have an idea about the blinking power light on the CPU. {i fear the worst, but i'm a pissimist}

Answer:Flashing Power Light CPU, ruh-roh?

Your probably going to have to open up your case. Are the fans spinning? Also, you may have to try a different cpu.(I know you dont want to) If it works with another cpu, then you know. If the fans arent spinning, i would try new ones. Swapping Power supplys if available. If all else fails, im thinking your mobo died.

My dad recently tried to install new ram in his computer (not mine in case you remember that topic) but when he did the computer wouldnt turn on and the power light constantly blinked, quite rapidly. Thinking that the new ram might be the problem he took it out, put the old back in and it STILL wouldnt turn on, and the light still blinks. Apparently it happend last time he unplugged his computer, although i don't know why he did it then. He said that last time he set ti aside and later (week+) plugged it back in and it worked. What would the problem be and how could we fix it?

He has a Dell 4700C.

Question: orange power light

i have the optiplex gx620 mini tower and i opened it too clean the fan from dust did that and when assembled it back together it wouldnt turn on and the power and mother board turned orange can someone help me with a step by step process on how to fix it and if i cant how can i get the stuff i saved on there off the hard drive

Answer:orange power light

Hi HitDat,
Thanks for writing to us. Do you see green light on the PSU at the rear side? Ensure the power cable is plugged in properly as well as the PSU connector on the motherboard is tightly secured. Re-seat the memory modules one by one and try with one module at a time and check. Regarding the data on hard drive, we would suggest to take the drive to a local store and get it backed up, or you can try the HD on another machine if possible and if it recognizes, you can back up the same.
do provide us your system tag#, email address and name via private message.
regards

first of all, i use a powerstrip for my computer. on this powerstrip i have just my little speakers and my alarm clock hooked up. i got home today and i unplugged everything to bring it into another room. (because i had just reformated it and my linksys wireless wasnt working and i was gona call them, anyways...) i pluged the power cord right into the wall, pressed the power button, and no go. i checked the cord and it was pluged in, then i noticed the power light (right under the cord connection in the back) was flashing (not rapidly, like once a second, idk if that matters). i brought it back into my room and pluged it in where i always had and it still wouldnt power up. the only thing i can think of is that my powersupply might have got a surge, so before i buy one, i thought there might look into other possible answers. any suggestions would be appreciated! thanks  notes: the computer was off when i unplugged iti dont know anything about power supplies. hahaif u need any info on it though i can provide it (i do know where that is)

hi, i have a laptop. The led green light has always been on when it is plugged in and even when it is shut down and plugged in. I heard a noise in the fan like a bug zapper noise. Then my light went out. It has not come back on. I need to see this light; it tells me I have power going into my laptop. It is charged 100%. The other lights are working. When I am working in my computer the green light is on. It goes out when I close the lid; or shut it down. My Charging Adapter Light is on and there is no problem. I just want to see my green light on my laptop. Any help is appreciated. Thanks

Answer:power led light not on when plugged in

LEDs do occasionally fail.  I'd say this is connected to the noise you heard but the fact that your PC is functioning fine makes me think that's unlikely.
 
If you disconnect the power supply, let the battery run down some, and reconnect the power supply does the icon in the system tray show charging?  Does the battery actually charge up to 100%?
 
If the answer to both of those questions is, "Yes," then this is nothing worth worrying about.

I have a dell mini 10v that uses windows xp. week before last i noticed that my computer's power light was blinking red. what could be causing this problem? when I touch the charger, ever so lightly, or barely touch the pc, the computer will power off. after jiggling the wire to the charger, the power light comes back on, and is blinking red. sometimes i do not even have to touch the pc, it powers off on its own.

i then have to press the power button for the computer to start up.

i was told i needed a new charger, which i purchased, but the power light is still blinking red. i went to the power option and my battery is at 55% and does not change. what is causing this? do I need a new battery? i checked to see if my power option was set on stand by. it was and so i changed it, but the light is still blinking red. does anybody have any suggestions?

i was told t remove the battery for a few minutes and then reinstall, but i cringe at having to do that. the screws in the back are so small i am not sure i can even get the panel out, but if i have to, then i will.

what should i do? thanks for the help

Hello, Sorry for the weird question, but is it possible to switch off/disable the power light (bright light in the power button) for B40? I understand that it sounds crazy, but it is in our bedroom and in the dark the blinking light of the power button really becomes an issue. Thanks,Alex

Answer:Bright Power Light (B40 All-in-one)

Welcome to the Lenovo Community !
 
I'm not an owner of your model, but in reviewing the User Guide and Hardware Maintenance Manual for the B40 I see no option to disable that light.  I assume the light is blinking due to the computer being a sleep or hibernated.  If so, you might try try shutting Windows completely down at night.  If you prefer to leave the computer on 24 / 7 then I would just put a piece of masking tape lightly over the button to dim its light.

I have a Lenovo B540 thats a few years old. Yesterday morning i woke up to use it and the screen will not come on. No boot screen, nothing. i tried to see if it was asleep so i moved the mouse and keyboard and still nothing. the only thing that seems to work is the power button which lights up and the light on the far right of the screen. so far i have tried:i tried unplugging it and pressing the power button and letting it power down and plugging everything back in, nothing.tried hooking up an hdmi cable to view on tv and nothing.i tried removing the hard drive and the ram and nothing. Any ideas? Like i said the only thing that light up is the actual power button and the touch button to the right of the monitor. which will also on occasion slowly blink. and i can also hear the hard drive

It just did this? Did it crash the day before, or before? Perhaps do you know about a power outage or surge?

Dear Customer, Try the following. Open Settings and select System.  Select Power and sleep, then click on Additional power settings - in the following window, click on 'Choose what the power button does' in the left hand pane. In the subsequent window, first click on 'Change settings that are currently unavailable' ( near the top of the Window ) and then remove the checkmark from the box against 'Turn on fast start-up (recommended)'.  Click the Save Settings button, then close any open windows and restart the notebook. When windows has reloaded, download the IMEI driver directly from Intel on the following link, unzip the package and run the installer. https://downloadcenter.intel.com/download/26127/Intel-Management-Engine-Consumer-Driver-for-Intel-NU... When the installation has completed, restart the notebook. When the machine has reloaded, re-enable Fast Start-up and reboot the notebook once again - let Windows fully load for a few minutes before checking.

I found a 1.7 ghz p4 motherboard on the cheap to upgrade my old p3 667, and i bought it in "working" condition, but i don't think so. Anyways, i got a pentium 4 support psu hooked up, and some pc-800/8 ram (it takes pc-800, would it work with pc-800/8?), and powered it on, and it just makes some strange beep code, followed by 1-1-1-1 beep code, but it dosen't post or show the bios, just a blank screen. So i reset the bios by taking out the battery for about 8 hours to ensure there was no charge left, and powered it back on, now it does not beep, but the power light just blinks, and still no screen.

Anyways, it is an HP-Vectra VL-800 motherboard
P4 1.7 ghz socket 423
pc-800/8 (takes pc-800 ram, but i think 800/8 works?)
the cpu fan comes on if that is any help.

I have 2 old Windows 98 computers (A Gateway and Compaq) that I received a few months ago. I played with them a bit, cleaned them up and put them in a box. :cool

I got the Gateway back out today, hooked everything up, and pressed the power button. The keyboard flashed once, and the power light remained yellow. No display, fans, beeps, nothing. Okay, something must be wrong with the power supply. Its original went out with a bang and the one in it was probably on its last legs.

So I get the other one out and hook it all up, press power button, and the power light remains yellow. Again no fans, sounds, nothing but the keyboard flashing once. :confused

What does a constant yellow power light mean?
 

Answer:Yellow power light - What does this mean?

Have you tried disconnecting all connections and reinserting to ensure a good contact?
Possibly also the CMOS battery is dead. Cheap and easy to replace.

Okay, put this thing together finally. An AMD Athlon 950 with a NEW power supply since the old one was making nice burning smells. So for the whole night while I was in the kitchen installing stuff it worked perfect (about 2 hours). Then I move it to a different room and hook it up and now it won't work. Two problems: 1) No go, no beeps (MSI Athlon motherboard) and 2) When I hold down the power button to turn it off it shuts off but the power button is still glowing green for some reason...

Anyway when I turn it on power comes on, CPU fan spins...then it all sits there doing nothing....monitor sits blank and has an orange light not a green one. Tried different monitor, same. Tried different video card, same. Isn't the PSU since it's new (no smells either). I checked all the connections they're fine. Could the power button thing have something to do with it? I know that isn't right...

Thanks,

Recently purchased the Aspire TC-705 desktop. Everything is fine. But I do have question on the power button light behavior that puzzles me. On occasion the power button will continously blink white while the system presumably goes into sleep mode but sometimes it will not blink but instead exhibits the stead white light. So the question is: Why does this desktop power button light blink and sometimes not while in sleep mode?" Running 8.1 windowsset to turn off display after 10 minutesset to turn off disk after 20 minutesset to enter sleep mode after 30 minutes  













Solved!

Go to Solution.

Answer:TC-705 Power button light

If the power light isn't blinking, then it's not in sleep mode.  Your monitor might be in sleep mode, but your computer isn't. There's several things that can prevent your computer from sleeping at the designated time (with inactivity).  One of the most common culprits is Windows Media Player (multimedia).  You can check your advanced power settings to change "prevent idling to sleep".

Ok this probably sounds really nitpicky but my boss's laptop wont display the external light showing that its plugged in to power. It works while on the port replicator just fine, but when just using the AC adapter, the light does not come on. The ac power is in fact working because i can power it up without the battery, and the battery/ac power icon changes when i plug or unplug the power. Any one have any ideas? I have tried 4 different power adapters.
