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?

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

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

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".

Answer:power button light

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.

Not sure if this is where I should put this or not, but I have a problem.

When I shut down the computer, the fan stays running and the light on
the power button remains lit with a yellow/amber color. What could be
causing this?

It just started happening yesterday. The only way to get the computer
back up is to unplug it and plug it back in. Pushing the power button
when it is like that does not work.

It is an e-machine, 2.7 GHz Intel Celeron, 80 GB with 1G Ram and I have
Windows XP
 

Answer:Power button light stays on??

How are you shutting down? Just hitting the button? Has the machine been configured to go into standby when that happens, instead of powering off? Does it work when you click Start --> Shut Down, and select Shutdown?

Here's how to check:

1. Right-click on the desktop
2. Select 'Properties'
3. On the 'Display Properties' dialog, select the 'Screen Saver' tab
4. Under 'Monitor Power' press the 'Power' button
5. On the 'Power Options Properties' dialog, select the 'Advanced' tab

The setting we are looking for is listed here under 'Power Buttons'. If this is set to standby, it will generate the symptoms you are experiencing.

Dell optiplex 755, mini tower . My son pressed power button and computer made an ear-piercing noise and would not boot up. The power light comes on, but no fan, no post, no beep codes. Monitor displays "no signal". Is this a bad power supply? Bad motherboard? Not sure where to start, need HELP!
 

Answer:Power button light on, no boot.

Npbptexas said:


... and computer made an ear-piercing noise and would not boot up.Click to expand...

do you mean a single beep, or multiple beeps? These codes will identify the issue.

Specifically with Dell desktops, you can refer to these beep codes:
1 beep: BIOS ROM corruption or failure
2 beeps: RAM not detected
3 beeps: Motherboard failure
4 beeps: RAM failure
5 beeps: CMOS Battery failure
6 beeps: GPU failure
7 beeps: Bad CPU

Additional Dell error information can be found here.

http://www.tomshardware.co.uk/forum/6230-2-orange-light-dell-gx270-power-button
1. Plug the computer into a power strip that has an on/off switch. Turn the power strip on. Press the computer power on button to start as normal, but after after one second turn off the power strip switch just long enough for the fans on the computer to slow down, but the amber computer led doesn't turn off and then turn the power strip switch back on. Computer should start and run fine. Computer typically can be shut down for up to 5 minutes and restarted normally--any longer and you have to sue the power strip power switch routine again.Click to expand...

Hi,
Vostro 460 Mid Tower system, circa May 2012, Core i5-2400, Windows 7 Pro 64 bit
I noticed that recently the light in the power button is completely out. No blue, no amber, no steady, no blinking light - nothing.
Other than that, the PC works just fine. Turns on, runs, everything else is fine.
It's just a little disconcerting, because when it goes into powersave, there's no visual indication that the computer is on.
Any thoughts about what this might be? Loose connection to the motherboard? Are power button LED's in the Vostro 460 known to burn out?
Thanks

Answer:Vostro 460 - No light in power button

Led is burn out. You can grab a similar LED bulb and replace the old one. This will be a simple soldering exercise.

My roommate tried to "fix" his PC but god knows he doesn't know crap. The PC acts like it is going to turn on, but the light on the front of the tower does not light up, nor does the display. The light on the motherboard is solid green, and he is still able to charge a phone through the PC, so I'm guessing the power supply is good if it can do all of this. At this point I am at a loss because I'm normally very good with this stuff, any suggestions? and I don't believe it's the video card.

I bought this laptop few days ago and from the beginning i noticed that light around my power button is not working.

so now i'm in dillema to return it or not?

Everything else is working fine,but because of it's price i expected to work properly.

And what may be the reason for that?

Tnx

Answer:Satellite P50-B-103 - light around power button is not working

As far as I know the power button or to be more precise, the margin around the power button should be lit / illuminated.

In my opinion its not serious issue but if it?s a problem for you and you are not satisfied with that, I would recommend you to contact the dealer in order to replace the unit.

Hi there,My son's computer recently started having this problem in which, after 5 minutes of the computer running, and running fine at that, it suddenly closes down immediately, but yet, is not switched off: the power button which usually is a constant green starts to slowly flash yellow and the only way to stop this is to switch the computer off. Whenever he switches it back on it does the same thing, works fine for 5 minutes and then switches to nothing but the flashing yellow light, we have even tried it in safe mode and the same thing happens.Just to give some info which might help you, the computer is a Dell Dimension 5000 running windows xp home edition. The last time before the problem started, the computer had been left on for around 20 hours, and this has been happening for around 12 hours now. He did replace his graphics card recently, but that was 3 months ago and he hasn't noticed anything wrong with it in that timeIs this easily fixable or will a professional have to be brought in, and if so would it just be worth backing up the necessary dataand buying a laptop to replace it, as he is off to university in a couple of years so will need a new computer soon anyway.Well thank you in advance, just ask if you need anymore information about the computer, i'll do my best.Thanks!

Answer:light on keyboard but power button inoperative?

Things like "screen went white" and "keyboard light on but doesn't seem to power up."It will help if you can describle what happens when switching on from "cold".... any sounds of fans or disks, any lights come on at all except the keyboard's "power" light?Do you hear any beeps? Does the monitor stay black or show any messages at all?A long shot, but worth doing if you are happy to look inside the box, is to make absolutely sure the video card is properly pushed home and the data cable at the back of the computer is well connected.

Welcome to the Lenovo Community !
 
The power button light is incorporated right into the motherboard circuitry and it is not something the owner can repair. Chances are the Lenovo Service Center will have to replace the motherboard in order to fix the problem.
 
As for Lenovo Support fixing the problem under warranty, that question would be best asked of the service center in your country as I can not answer that.  You can find the phone number for Lenovo Support in your country or area by using the link below....http://support.lenovo.com/us/en/supportphonelist_alt1

Can someone tell me for sure that the LED on the power button is supposed to light up?  I swear mine worked.  I sent it to Dell to have the hinge problem fixed, which I see a lot of you had issues with.  Well, when I got it back the light no longer comes on.  Dell is trying to say it never came on.  That this model doesn't have a light.  I said, why does it have the rectangle clear lens for a light?  They just keep saying it doesn't have one.  They said they would send a copy of specs that show this.  Never did.  I have several people that agree with me.  But, looking for more support to confront Dell.

To be clear, my PC turns on and seems to run exactly as it should, so this is possibly more of a cosmetic/superficial issue. The little light located on the power button no longer lights up when the PC is powered on. Strangely, the light still blinks on and off as it should when the PC is in sleep mode, so the light still has some functionality.My PC is only a couple of months old, so I'm just a little concerned that this could be a sign of things to come. I hope that other components don't start failing on me.Does anyone here have any possible explanations?Thanks.

Just faced a rather strange issue, but not really an issue, just different system behaviour than expected. System:W520 Batteries:55++ connected27++ connected Power adapter:Unplugged No other accessories connected. Scenario:I was using the system till it power itself off due to low power (0% reached for both batteries). i.e. Ungraceful Windows shutdown. Then upon pressing the power on button, the LEDs flashes, no THINKPAD logo or BIOS message appears, system appears to then restart again, and the LEDs flash again...and loops until it was no longer able to even attempt to POST. Expected behaviour:Either display the message that says "Battery level is too low".OrDon't loop (this is the behaviour when only the 55++ battery is connected at 0%) Why does having the 27++ would make the system go through this looping cycle?

Answer:W520, 55++, 27++, unplugged from power adapter, 0% battery. Press Power button --> power up loops.

Hello Chatbox,
 
I can understand your issue very well, as there is no message comes on the screen which gives you information to plug the power adapter and prevent the laptop to get shut down.
 
You should install Power Manager software and then customize it as per your requirement.
The software can be download from the mentioned below web link.
http://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles/8mu417ww.exe
 
 
Hope, after this laptop will not shut down automatically due to battery backup

Press the NOVO button on side of the laptop and let me know what happens? If nothing happens, then (if you are comfortable), open the laptop and remove the HDD. Power up the laptop and let me know what happens. You can also try removing the RAM, if you have 2 sticks, could be that one of them is faulty. Just try booting with either one.

Welcome to the Forums.
 
From your description, it looks like there's a problem with the Sensor Board (this is the area where power and touch buttons are located).

1. Unplug the charger / adapter. 2. Remove the battery. (If your model has a removable battery, not an internal one)3. Press and hold the Power Button for 15 seconds. 4. Re-install the battery, plug in the charger / adapter if needed and power up the system to see if the problem was resolved.

Day before yesterday when I was trying to start my laptop, the light turned on-off continuously several times, and finally the power key light turned on but the screen was black.And yesterday the light turned on-off thrice. But after that every time I turned it, the power button light got on, but the screen was black.Present situation: On starting my laptop, the power key light is on, but the screen persists to be black, not getting on-off on it's own. I found one solution, of removing the battery as well as charger and pressing the power key for about 60 seconds. But it didn't help.Please suggest what might the problem be and solutions!!

My fiancée's HP G62 laptop suddenly stopped booting. More specifically, when you press the power button, the power light comes on, but the screen stays totally black. I tried doing a hard reset on it (unplug, remove the battery, and hold power button down for 60 seconds), but that didn't work.  I tried this multiple times with no success. I shined a flashlight on the screen to see if there was a faint image (indicating a backlight problem), but there is no image at all. I tried connecting the computer to an external monitor, and that didn't work either.   Recently I had to replace the fan and the power button assembly on this machine, but it was working fine after that until now.

I have a Dell Latitude E5250. When plugging in the AC adapter the only light that comes on is the power button light and it's blinking continuously. The other indicator lights are off. The system board has been replaced, no change. After the system board was replaced the battery indicator light came on and the battery charged, though the laptop would not power on when the power button was pressed. It would light up then go out.  I've removed the battery and AC adapter, held down the power button to discharge flea power, no change. Followed Dell TechDirect directions to remove the battery and CMOS battery, then insert the AC adapter and power on the laptop, no change. I've tried known good RAM. I've removed all components including the LCD cable, no change. When the AC adapter is installed the power button light blinks continuously, no pattern, no other indicator lights come on. Any thoughts? I'm wondering if it's a video issue, bad Touch LCD?
Thanks.

I have a Satellite P755-103. I upgraded the BIOS from version 2.6 to version 2.7 (file bios-20121002102409.zip) dated 17-09-2012. Since then, I noticed the light in the power button started to act randomly. It usually is on, sometimes it dims, sometimes it goes off, sometimes it blinks. I could not find any apparent reason for it. It also happens during the BIOS pre-boot phase, working on battery and working with the power supply on.

Any advice?

Thanks,
Paulo Pereira, Portugal

Answer:Satellite P755-103 power button light blinking randomly

Hi

Are you sure you are talking about power LED indicator and not HDD indicator.

The first from left is the DC indicator and it glows white when power is being correctly supplied from AC adaptor.

The 2nd from left is power indicator and it glows white when the computer is turned on.
But if you turn off the unit and goes into sleep mode, this led flashes amber.

The 3rd is battery indicator.

The 4th from left is HDD / CD/DVD drive indicator and it blinks whenever the notebook is accessing the HDD or reads from disk

Hi guys well I just hope someone with some electronics knowledge in repairing notebooks would help me out in here.
I got a sager 5680 lappy, and when I plug the lap on AC power without the battery I turn on the unit and instantly goes off, ( I hear a low sparky noise like some sort of short circuit, when this happens the psu light dimms from rock solid ) .
Now if you leave the unit with the battery charging you may be lucky and the battery will charge and the only way the unit works is with the battery on it's bay, as soon as you remove the battery boom unit shuts off.

The Unit does work but only when you plug in a battery and when it charges if you leave it dunno a couple of nights never gets solid green

What I did :
==================

- Could the PSU be bad not throwing enough amps ? even if it shows voltage
on digital meter

- This lap has a separate voltage daughtercard for the battery I removed it when diagnosing this card goes
plugged onto the mainboard and here the battery gets plugged.

- Measured PSU voltage it's working fine 20volts DC

- Checked SMD fuse on motherboard , fine

- Dissasembled the entire unit ripped everything off that might me faulty

- I've read the AC plug sometimes get's broken and I retouched the solder points, once I did this, by miracle the unit started without the battery plugged on. But guess what after I assembled the unit then again , when on AC power alone turned on , and then went off . So I don�... Read more

Answer:laptop not starting on AC , power light on , I press on button & goes off instantly

The power adapters and the power sockets have an extremely high failure rate in the Sager 5680 laptop. We have seen eight of them in our shop with identical symptoms. While still under warranty, Sager replaced those without a question.

The problem appears to be where the power meets the motherboard. New parts would need to be re-soldered into the system... expensive because it is very time consuming.

Sorry I don't have a solution for you. Working units are available on eBay, if you want to trace the problem between a working model and a failed one.

I have a dell dimension 8100 that has been powerleaped from a 1.7 to a 2.5.  I recently upgraded the RAM from 256 PC 800 RDRam to 512.  I also have upgraded from a GEForce 2 Ultra to a GEForce 4 Ti4600 quite a while back.  Everything has been working great until the last week or so and I am at a loss here.  I used to leave my computer on all the time 24/7 with reboots here and there when I needed to.  Well, after I lost the fan on my Video card I started to turn it off.  After about six months of this it decided that it doesn't like to boot up after a night or two of being off.  What happens is when I push the power button you can hear it power on but the monitor says there is no signal being sent from the computer.  The other weird thing is that the power button light is amber instead of green.  I turned off the computer and unplugged all power from it and tried again.  This time it booted up.  The last time it happened, unplugging it didn't even work so I pulled the case apart and cleaned it out.  I yanked the Video card out of the AGP slot and reseated it and turned it on and presto it fired right up.  What gets me is when I leave it on and have to reboot it, everything works fine.  It only acts up when I leave it off over night or longer and then start it.  Could this be the battery on the motherboard?  My clock doesn't seem to be losing time in windows or anything.  If a...

Answer:Dimension 8100 not booting up and has amber light on power button. Please HELP?

If the power button is blinking amber, it is probable that the power supply needs to be replaced.If the power button is solid amber, the power supply should be fine. At this stage of bootup, memory has not yet been tested, and is not a factor in this type of failure. Check the CPU and ensure that it is properly seated.

I have an Inspiron 3650 i3 desktop pc that is a few years old and seldom used. When not in use it is in sleep mode.
Yesterday i tried taking it out of sleep mode, with no luck, and noticed the power button light was solid orange. After a few tries I hard reset the pc and it would not boot up completely. The fans come on and the harddrive sounds like its working but i get no video and the power button remained solid orange. After troubleshooting from several forums i ended up disconnecting everything from the motherboard and taking out the battery then after replacing it and trying to boot with just the cpu fan plugged in. same result, solid orange power button. The PSU seems to be working fine after troubleshooting it so im thinking its either the processor or mobo that has gone bad. Any suggestions?

Hi everybody,
I recently inherited an unused PC from work. It's an Optiplex 780 with a faulty power supply.
I replaced the power supply with a working one from an old Optiplex 740 and also had to buy an standard ATX 24 pin to mini ATX 24 pin cable in order to use the 740' PSU in my Optiplex 780.
I have plugged in the power cord (but no mouse & keyboard because I don't have any USB keyboard available) and I expected the computer to show DELL logo as well as on screen POST messages during power up but instead I can see the following :
1) Power button in orange color. No blinking. : according to service manual it means PSU is probably OK and PC has reach booting stage 2.
2) 1,2 & 4 green diagnostic lights are on. This combination (1,2,4) is not listed in service manual so I have no idea on the possible kind of error.
Any suggestions about the possible error and how to fix it?
Kind regards,

There are no lights on. Does this mean my battery is fried. Originally i thought the jack needed replaced, but the guy told me it was just my cord which Best Buy confirmed. So after getting the new cord i have this new problem. Usally there is a battery indicator light on when the battery is in and it is plugged in.

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.

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.

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.

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.

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.

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.

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...

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.

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?


help!
thanks,
 

Answer:HP Mini 210 - 1030NR Won't power on, No power light, need voltage expert

Hello, my T500 does not turn on, no lights are lit, battery not charging. I tried to turn in the dock, but nothing. I tried to insert a fully charged battery but nothing too. Will probably be something wrong with the motherboard, maybe some fuse, but do not know where to look. Thanks for help

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.

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 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.
