Power button light on, no boot.

Question: Power button light on, no boot.

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!

Preferred Solution: Power button light on, no boot.

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.)

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

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

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 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?

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.

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".

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!

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...

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.

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.

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.

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.

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.

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.

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!

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.

Answer:power button light not work anymore

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

Sorry to hear of your problem.  What model do you have ?
 
Try clearing the CMOS to see if that will resolve the start up problem.  Just do this....
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.

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.

Answer:Lenovo y570 power button light problem

hi Stefy333,
 
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).

You can try to reseat the sensor board to isolate any possibliity of a loose connection but if this doesn't work, you may need to replace this part.

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?

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 t3400 (core duo e8400, 4gb Ram...) which was powered by the oem psu, but I changed it to a corsair vs450 so I could power my gpu. Two months later, after taking the gpu and psu to another pc, I put the oem psu back into the dell, and tried to power on, but there is a blinking orange light in the power button. I doubt it is a mobo problem, because it was working today. Any ideas?

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.

Power button LED light is not lighting up on DELL Inspiron 5559. Is it normal?

Answer:Power button LED light not lighting up on DELL Inspiron 5559

 Good question.  I have the same problem with my 4 month old 5559.  The description in the reference guide says "Indicates the power and battery?charge status.  Press Fn+H to toggle this light between hard?drive activity light and battery?status light."  If I press Fn+H, sure enough it shows hard drive activity.    Confession time:  I never saw this in the documentation until I looked it up to reply to your question today!  I never knew I had a disk activity light - man, I'm glad to have found this!  :-)

My fiance'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.

Hi,
I have an old Optiplex GX240 that had its power supply break, I recently got another power supply from a different computer. The Power supply is working however there is an orange light on the motherboard and power button that doesn't flash. The ABCD lights on the back of the computer are also not lit.

Answer:Orange Light On Power Button and Motherboard - Dell Optiplex GX240

GX240 requires specific NON PFC power supply.  This unit is 16 years old now and has 512 meg ram of the PC133 variety.   A newer model like an optiplex GX620 or better is still viable.  This system is TOO OLD and TOO Slow to be of any use.

Hi becks88,

Sounds like a serious hardware problem... Can you start the notebook without AC/DC adaptor or is the adaptor charging the battery?

Try also removing the AC/DC adaptor and battery for one hour at least. After this connect both again and try to start the notebook.

In worst case you need professional help from an authorized service provider? :(

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,
Beltrixx

Answer:Optiplex 780 - unknown diagnostic light code 1,2,4 plus orange power button

Hello!  I would unplug everything go into the computer and unplug any cards you have like graphics card and network cards etc. Also unplug your HDD and Optical Drives and plug them all back in and see if that clears it.  I looked at the manuals you did and just combined 1,2 and just 4.

I just received my replacment AC adaptor. I put my battery back in and plugged the laptop in, but when i push the power button the battery indicator light flashes red four times. 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 tryed taking out the battery, unplugging it and holding the power button down, but that didnt work. I also tryed it without the battery in. Is my battery just bad? Thanks for any help.

Hi Harsh,
 
Welcome to Lenovo Community!
 
I?m sorry to hear that your Y510p Laptop is not turning ON. I suggest you to perform the Flee-Power, below are the steps to perform the same:
 

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 Flee-Power, I would suggest you to contact our Technical Support for further Assistance to get the details of the nearest Authorized Service Center to get the issue analyzed.

Hi All,
I have replaced a EVGA GT 730 video card with the EVGA GTX 1070 Founder's Edition video card on a Dell XPS 8700. Once the installation was finished I powered the PC on and only got an amber light on the power button. I powered off and replaced the card with the old one, checked for any loose cables, and tested the power supply successfully. I am still getting an amber light with the old card back in.

This has gone from bad to worse. It started with an error message when I went to close down, to the effect that the Start Button wasn't working and would reset on restart. I restarted; it didn't reset. I could use programs but the Start button still wouldn't work. I tried to restart in Safe Mode, but the computer wouldn't go into Safe Mode -- I got the screens that let me select reset but the final step that would select Safe Mode with Networking just got skipped. I'm a little sketchy on what I did next (I got kind of ticked and had to step away from the computer for about a week to cool off, and I'm afraid I didn't write out a history while it was still fresh in my mind) but I tried a variety of things to force it to start in Safe Mode and the result is that it doesn't start at all now: the power light comes on, but the screen stays blank and there's no action on the drives.

Look in the FAQ's or the manuals for how to reset the CMOS and that will probably fix it.
Your system has gotten stuck in a power save state.
The E510's need a BIOS upgrade (under downloads) to fixe several problems. Get it too

Hello!
My father-in-laws desktop computer is acting funny. When the power button is pushed on the light around the button comes on and the fan starts but thats all it does. The fan usually comes on and is quite loud and then it quiets down and you hear the rest of the computer booting up. Nothing is on the monitor except "no signal" and the fan is the only thing heard running. It worked fine the day before and it was shut down properly.

Any thoughts?

Thanks
 

Answer:Computer won't boot but fan and power light is on

The first thing I would try is to make sure that all the connections to the monitor are tight. If they are, I would try another, known to be working, monitor and cables to eliminate that problem.

Hi, I wonder if someone out there could help me with a problem?

I was using my M2 on Friday when my friend accidentally knocked a very small amount of soft drink onto the front of my M2, I immediately put it upright and got a hairdryer on it.

After leaving it an hour I tried using it and everything was working as before which was a great relief, however a day later I was using the M2 to check my e-mail when all of a sudden in went off.

The power light is on was still on and so was the light that indicates I have a CD drive slotted in, I tried many times and it would not boot up, so I left again for a day and yesteday morning it looked like it was booting up only to freeze on the Windows screen, it then did it again and it hasn't booted up since.

Could anyone please give me some advice on what I could possibly do to fix this problem?

Regards,

Russ

Answer:Tecra M2 - Will not boot up, power light is on

Hello Russ

Please be realistic. What you can do in this situation? Not much! You can try to start the unit. See if you can enter the BIOS and if yes how long the unit stays ON. If the unit works for a longer period you can try to boot up from CD (for example with recovery media).

You can try to connect HDD as external one to other notebook and try to save all your important data and install OS again. More than that is not possible. If there is some electronic malfunction it is not easy to fix it on your own and helps just technical investigation to see which hardware component is damaged.

I have had this custom built PC for a couple of months. All of a sudden when i pressed shut off on Windows 10 and went to bed, it stopped working. The fans wont start, I don't hear running from my SSD or hardrive, however the light that indicates the PC is on remains on. I have unplugged my power supply and unplugged my surge protector from the wall and it remains on. The only way i can get the LED to turn off is by unplugging from the motherboard. My specs are here ---> http://pcpartpicker.com/b/Mhhqqs

shut down disconntied cleaned with vacum and air hooked back up power botton started flashing and didnt boot up

Answer:hp power light flashing wont boot up

I hope you don't mean a household vacuum. Check all the wiring to make sure you didn't pull something loose. If you used a metal nozzle vacuum, you could have fried the mobo.

we had a storm the other day and think a power surge hit my computer, even though it was on a surge protector. I also lost the vcr with the surge so i know it's not a virus problem.we think it was the lighting that hit close to the house. the computer i have is an e-machine t1105 with windows xp. When i push the power button on the computer the light dosen't come on but the fan starts and it sounds like it's running. the cd rom will still open but won't seem to load anything. i tryed the reboot disk to see if it would read but i get nothing but black screen and monitor says check pc the screen is ok. the green light on the back off pc where plug goes is still lighting up green. Is there any hope for my computer? even if there isn't any hope do you think the data on hard drive may be retreivable? or a part that i could have switched out and have a computer again without having to purchase a new one?
 

Answer:storm came now computer won't boot and power light off

Sure doesn't sound good

Off top of my head, fan spins, nothing else comes 'on', possible

Memory / CPU / Video card / Motherboard malfunction.
PS: if fan comes on, but no power light, could be a faulty/buggered up power supply too I suppose ( I woulda thunk the power light would come on before any fans spun )

DOH !!! can't even blame Microsoft on that either.... its hardware.
Is it a microsoft computer?? hehe

Gateway DX4640 desktop froze in the middle of viewing IGN.com.

It required a hard re-boot. Now I get a slow flashing power light. Fan starts but it won?t boot. I tried bootable CD with no success, although the CD drive does spin when a CD is inside.

We tried the following:
1. unplugging power and then depressing power bottom for a minute to discharge battery.
2. pulling out the memory cards one at a time, and then booted with just one memory card at a time without success.
3. removed battery and reinserted after 10 minutes

I would appreciate any advice you might have.
Thanks.
 

Answer:Slow Flashing power light – no boot

This is a common issue with Gateway machines, it is down to the onboard Video chip overheating and failing, though this mostly happens with laptops!! have you got a spare vid card lying around or can you borrow one from another machine and try it in agp/pci/pcie expansion slot, to rule it out ??

I was upgrading this computer to Windows 10, I had done an in place install but the kids had spyware that was showing up even then. I did a refresh, it failed I did an install and finally got into windows. Installed a couple updates and rebooted.
The computer has been bricked since. The only thing that is happening is the LED that indicates the power above the button will not stop flashing white. Plugged in or not plugged in, after holding down the power button for 5, 10 and 30 seconds, The power light stops flashing for a moment and then starts again. I tried multiple outlets. No clue unless it is coincidental hardware failure.

Answer:XPS 18 will not boot, power light will not stop blinking

I'll ammend that.  I went back in and re-removed the battery cable.  I also removed the CMOS battery cable this time... that at least got me to an onscreen error message and access to BIOS!

Hey all,

Weird one here. Got myself a new graphics card the other day, upgrading from a Radeon x1650 pro, which died after 4 odd years of good service, to the Radeon HD5450, and everything seems to have gone successful except for since installing it, when I press the power button to boot, the PC's power light will blink 7 times and then boot up normally on the 8th blink.

I was kinda in 2 minds about whether or not to troubleshoot this if I'm honest, but figured I might as well in case it could be causing some kinda damage. I can't see any error's appearing, nothing in event logs, as far as I can tell the PSU should be more than capable, everything seems to be performing as expected, it's just these 8 blinks before the system starts to boot.

I've reseated the memory and Graphics and tried booting with a few non-essential components disconnected, which fixed it for the first boot, but the issue reappeared for every boot after that.

As well as my listed components I've also got a PCI NIC (D-link DGE-528T), wireless KBoard + Mouse, USB Wireless Adapter, a SATA DVD RW and a couple of fans (1x80mm, 1x92mm and 1xLED120mm)

...any ideas?

Cheers,
Sean

trying to turn on toshiba tecra a8 laptop. the light on the power button flashes twice amber and once green and it won;t start up.

any suggestions?

Answer:Tecra A8: Power light flashing amber twice and won't boot

Remove the battery and (try) to start the notebook only with AC-Adaptor connected.
If your A8 behaves the same you have to bring it to service.

I am having an issue with my G7-1075dx. Power light comes on, amber light of WiFi glows, fan starts up and runs, and that's it: Blank screen and no further boot. I've done all the 'hard boot' and hardware investigations that I can think of: replacing hard drive, removing and resetting RAM modules, etc. No help. I have seen possible solutions listed for a device running Windows 7. My laptop runs Windows 8. Has there been any solutions given for this problem? I see by perusing the internet that this is not entirely uncommon, and up to this point this has been a great computer to work with. Help!!!

My HP Pavilion s5206 won't boot, fans working, green power light is on. Monitor won't come out of sleep and keyboard is dead.

Answer:computer won't boot,fans are working,power light on,

The monitor won't come out of standby mode until it gets a video signal from the PC, which it evidently is not getting. Coupled with the fact that the keyboard is not working, it's very likely a faulty motherboard.
