Power button light no longer turns on

Question: Power button light no longer turns on

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.

Preferred Solution: Power button light no longer turns on

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.)

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.

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!

Hello everybody!
I have a Dell Inspiron 3847 with an i5 4440, 8 gb of ram, and 1 tb of hard drive. I purchased an evga 500 watt PSU and successfully installed it. My pc worked normally and everything was fine. I then purchased an evga 1060 sc and attempted at installing it into my pc. After installing it I started up my pc and it turned on. The fan for the gpu didn?t spin so I turned off my computer, opened the case, unplugged the 6 pin then plugged it back in. I turned on my pc again but it made an odd sound before the power button flashing orange then completely shutting off. Now every time I turn it on the light turns orange and the fans spin for a split second then they stop. Any assistance will be much appreciated...

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

Hello, recently the light on the mute button stopped working. The mute itself does work...just the light never comes on.  I found some other posts about this, but thay all talked about an "IDT High Audio" driver being the issue. I don't have that driver, mine are all "Realtek". I tried updating those but it says they are up to date. Thanks for any help!

Answer:Mute button light no longer works

Hi, Try the following. Download the Realtek HD Audio installer on the link below and save it to your Downloads folder. http://ftp.hp.com/pub/softpaq/sp78501-79000/sp78784.exe When done, hold down the Windows key and press R Into the Run window, type devmgmt.msc and hit enter. In Device Manager, expand Sound, Video and Game Controllers.  Right click the Realtek device and select Uninstall - you should also get a prompt to remove the current driver, tick the box to allow this and then proceed with the uninstall. When complete, download and reinstall the Chipset driver on the following link. http://ftp.hp.com/pub/softpaq/sp78501-79000/sp78555.exe When the Chipset reinstallation has completed, restart the notebook. When windows has reloaded, open your Downloads folder, right click on the Realtek installer and select 'Run as Administrator' to start the installation.  When this has completed, restart the notebook again and let windows fully load for a few minutes before checking. Regards, DP-K

Hello, I recently noticed that the mute light (located on F5) had stopped turning on when I pressed it. Mute works, but the light doesn't come on. I understand, from previous posts, that this can be because of problems with the Audio Driver. However, I recently had to uninstall the default Audio Driver because of issues with this (also well known with HP products.) Is there anyway of getting the mute light back, without having to resort to the old Audio Driver?  Thanks.

The power light goes on for a second and the first light on the top right blinks for a second with the power light and that's it.  If I hold the power button for longer, it keeps repeating the same.  
Please help.

Answer:Inspiron 17R won't start. Only the first light turns on and of when I power up without the battery and Plugged power.

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.

Hi,
Wondering if someone could shine a little light my way. My boyfriend has an emachine desktop W4682 and just tonight it has started giving me two problems.
First when turning on the pc the power light turns on and stays on, you can hear the fan humming but nothing else happens... no signal to the monitor. Something that I noticed was that the light for the dvd+-rw drive stayed on too. Thinking that maybe the dvd drive might be the problem, I opened the tower and disconnected the dvd drive. So far so good. The pc turned on and booted completely. After a couple of minutes of using the pc I started getting an error that said "power surge on hub port" and all I could do (after reading a few posts here and there) is turn off the usb alert on the advanced options.
For now I am able to use the pc but I'm worried that I might be causing it some permanent damage by leaving it as is. Best idea yet is to buy a better power supply? Anybody got a better one?

*Not expecting miracles here. I know of the little potential the emachines have*
 

Answer:Power light turns on but nothing else happens

G'day Myzteryh, these kinds of problems present difficult answers, quite obviously there is a malfunction of some type but what is the best course of action.
It is possible that some kind of malfunction has happened within the DVD combo or some other problem has affected the DVD combo but not knowing becomes difficult. The usb indication also is a consideration.
You could take it to a shop but they probably would not do more than what I am about to suggest.
It would probably be pertinent to obtain "Everest Home" off the net, (google it, Lavalys) this is an analysis program that can be helpful, remove any unneccessary USB stuff, load the Everest program, if you are able to, open it, then open the computer icon in it, then open the sensors section. This will show voltages and temperatures within the machine. If you could somehow copy and paste that page here would be nice, reallly what we are most interested in is the voltage readings, you can expect the table to show suggested readings on the left and actual readings on the right. I do feel you may find some way to achieve this without much problem and we may be able to work out what may be happening.
Do not leave the machine running for any period longer than neccessary at this time. (give it some thought)
If any of the twelve volt readings are above 14 Volts just switch it off and replace the power unit without any further testing.
There may be other ideas on how to address this problem.

Cheers, qldit.

Hi Recently my Y580 started acting strange:While doing normal work it's rock stable and everything but when i turn on anything that demands high system performance (i.e. games) the whole system starts to go haywire - fps drop to minimal values, the power button led starts to blink and windows detects the computer as disconnected from the power supply. If i disconnect and reconnect the power adapter it works for a few seconds and goes crazy again. I have allready ordered a new power adapter since the old one is falling apart anyway but i wont get it till Tuesday.Any ideas are welcome - i feel comfortable about taking the whole machine apart if it helps. Now that i think of it i remember that the chasis shocked me once or twice recently - damaged power cable between power socket and motherboard? Thanks in advance

Answer:Y580 Blinking power button led and power supply turns off

Hi,
How many watts is your power brick rated at? I had a similar issue when I used a brick from another laptop. It had the right voltage and the same plug, but it was delivering less power than the original one. When doing basic office stuff it was working fine and charging the battery, but when gaming it would work fine for 2 minutes and then display the same symptoms as your Y580.
Hopefully you ordered the right, more powerful brick. I think the right one is rated at 90W, but I'm not sure.

Laptop: Toshiba Satellite 1005

Problem: When I push the power button and let go, immediately the laptop loses all power.

I'm using AC power cord, plugged into the laptop, the power LED is green, but when I press the power button and let go, immediately the power LED goes black(turns off), nothing happens.

Howerver, if I HOLD the power button down without letting it go, the LED power stays on but the laptop does not boot at all, no startup logo, no sound of anything.

This is the second time this has happend, the first time, I let it sit over night, and next morning it booted up fine.

Currently the laptop is cold, it hasn't been running, but still does the same thing as described above.

There were no changes made to the laptop.

Any ideas?

Answer:Satellite 1005: Pushing the power button, turns off the AC power.

It seems that the contact of the power button is faulty. Better bring the Notebook to a Toshiba Service Station for a check up.

I dont?t think that this is a Software failure.

Press the power-on button and it goes blue for a few seconds with barely a sound, if any. Definitely zero start-up whirring. Then it switches off.

The last thing I recall doing was sending the notebook into +sleep+ or +off+ mode - and before it had fully powered down I'd closed the lid.

Perhaps the battery was fully discharged at the same time by co-incidence, because, the next time I tried power-on - *nothing* - not even the blue power-on light. Only after fully recharging the battery did the power-on light work. But that's the only thing that works, now.

The unit is still under warranty and has never traveled outdoors, nor been mishandled.

Any assistance most appreciated before I resort to sending back to official Toshiba maintenance/repair.

If its caused by the emty RTC Battery, Where can I order a new one (In Europe?)

Answer:Satellite Pro 2100 - Power light turns into an orange dot

Hi

Normally this has nothing to do with a empty RTC battery. In this case you would only get an error message about a low CMOS battery or something else but the notebook would boot properly.

In your case I assume it?s a hardware problem. Have you already tried removing the battery and AC/DC adaptor for some hours or over night? Sometimes this helps?

Otherwise it would be great to get professional help form an authorized service provider. They can diagnose the notebook and exchange the faulty hardware parts.

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."

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".

HI Everyone,

I have a problem with the power indicator led. It gets on after I completely shutdown my laptop. After I close the lid the power light gets on and it remains on. No AC adapter is connected but still it gets on. I cant understand why?

I have read the Toshiba user manual in which it says:
1-The power indiacator led turns white if the laptop is ON.
2-The power indicator led? truns orange and flashes when the laptop is in sleep mode
3-And there is no other action performed by the power light..

As in my case, when I shutdown my laptop all the lights go off but after few seconds the power light (orange) turns on. Please help me to slove this.

Answer:Satellite L755-16L - Power light turns on after complete shutdown

Hello

Yes, that?s really strange and normally if you shutdown the computer (not standby) and disconnect the AC/DC adapter all LEDs should be off.

Since when do you notice the problem? Have you connected external devices to the notebook?

It?s new notebook model and probably it has something to do with BIOS. Have a look on Toshiba website if you can find a newer BIOS version:
http://eu.computers.toshiba-europe.com > Support & Downloads > Download Drivers

But before you start the update also read the BIOS update instructions from Toshiba. It gives you a lot of information about BIOS update procedure.

This happens off & on: My Gateway 5458E desktop will turn on, but the power light doesn't come on (should be blue) & there is no signal to the monitor. The computer powers up, can hear sounds (fan, etc), keyboard lights up, can see light from dvd player, but nothing on monitor & no power light. Have tried a different monitor with same results.The computer has also turned itself off while working ok a couple of times & wouldn't restart correctly until next day, but most of the time this happens when I try to do a restart or just turn on computer after being turned off.What could be causing it to start sometimes & not others?Thanks!

Answer:Gateway desktop turns on but power light not on & no signal to monitor.

A failing Power Supply sounds like the root cause of this issue.Any local computer store will be able to help you with one. The power supply is one of the most important parts of a computer.If they offer something really cheap, eg $30 it is not very good quality, the higher quality the better.Assuming you are using the machine as standard, a 350W PSU will cover you, however if you plan on getting a graphics card to play games or video edit ect a 500W minimum should be followed.

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.

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.

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...

When i turn on my HP Elitedesk I get a SOLID RED LIGHT on the power button that doesnt go away. I opened the case and blew it out with a can of air. I also re seated the Ram. I ren Quick Diagnostics but everything passed. The PC still boots up and works like normal. Does this indicate a bad HDD. What does a solid red light on the power button mean? Its not flashing or beeping. Remains solid red throuought use.

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.

Model: HP Pavillion 15 ak007txOriginal OS: FREE DOSCurrent OS: Windows 10 64 bit Problem: I tried to update the BIOS using this file:Released:2016-07-05File name: sp76335.exeVersion F.80It gave me a Blue Screen of Death and the computer restarted. After restarting I only get a blank screen, the fan also does not turn on, there's no text and no way to access the BIOS nor the boot menu.The Caps Lock led does not blink but the power button blinks every 2 seconds indefinitely,every time the light goes off a click sound is heard from my laptop. This, according to HP, suggests a BIOS Corruption Failure. What I've tried:I have removed the battery and tried to perform the hard reset procedure but that does not help.The only progres that i have had is that i tried the windows logo+b button and now the blinking stops and the power button stays on that too indefinitely.i have tried this method many times but to no avail. I also tried creating a usb bios recovery as mentioned by HP and tried the windows logo + B button combination but still nothing has happened.I hold the windows logo + B, then turn on the computer. Nothing happens. I have tried holding them for different lengths of time, there's no beeps, no text on the screen, nothing.  Please help me out,What am I missing?

Hi,

I have a Dell Inspiron 530 (desktop) with Vista Home Premium. Until the other day, when I pushed the power button to start the PC, it turned blue and the PC went through the boot-up process. Now, it turns yellow and nothing happens unless I do more. So I push and hold the power button until it turns off. Then, I push the button a bit more strongly and it turns blue and boots.

My first thought was that the power switch for this 2008 PC is getting old and that I may become unable to boot at all. So I have decided to just let it go into sleep mode for now rather than turning it off for the day.

Any ideas on solving the yellow light issue?

InfoHungry

Answer:Power button turns yellow instead of blue

It's an error indicator (not a failing switch).

Depending on the model, there may be other error indicators as well. In any case, q quick search found this: Inspiron 530 steady amber power light. - General Hardware - Desktop - Dell Community

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 all, I have a new ThinkPad E460, day old. One thing I noticed is that the power button has a small circle in the middle of it, however on pressing it, the small circle on the power button does not light up to a green light, like on the other ThinkPads. So my question is, is this supposed to light up to a small green light or is the abscence of the small green light normal behaviour. Any help will be greatly appreciated.

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.

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.

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.

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

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!

Some time ago, the PC gave the same problem. It wouldn't turn on. When I pressed the button, it turned on but showed nothing. I had replaced the CPU and that seemed to work. I didn't use the PC that much, rarely you know. But now, after some time, it gives the same problem.
It turns on, the front light is on, it makes the normal noise the pc makes when it's turned on , but if I try to shut it down by holding the power button it just doesn't work.
So again, I tried replacing the CPU and it worked again. I kept it all day working, just to be sure, and sometimes I would restart it and it would work again. No problems at all.
So I turned it off at night, and next morning it just would make the same problem. So I tried replacing the PSU. And it worked again.
Now while I had the PC with the new PSU, I tried to insert the old CPU, and again, it would turn on.
So I bought a new PSU and installed it. The same thing, tried restarting too, and it would work. But this morning the same problem happened.

I also tried another CPU today and yet no signs of working.
I don't know now what to think.

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 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

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 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.

We bought around 40 of these X220 I5 before xmas and now more than 20 of them have failed. The company we bought them from tried everything but they ended up switching the mainboard on the first two that failed.We were told it was a batch issue with the serial number R9-HNXXX and now all of those are changed into T420. But today we had the same problem with serial number R9-HXXXX that was bought two weeks earlier and with different config - I7 and SSD. All of them with the same problem that is described in subject. Are there any known batch issues? The problem is not with the tablet version and sorry for posting in the wrong forum. Thx

Answer:X220 - no post and green light around power button flashes every 3 - 4 second

I was preparing a X220 for a VP in my office and i left on vacation. When i came back, the laptop was dead and i can't power it on. I unplugged the AC and removed the battery and waited a bit, plugged everything in again and still the same thing. The battery LED blinks 3 times then nada. (no fans, nothing) I tried a little trick from the S model, removed AC and battery and pressed power button for 30secs and re-plugged everything but it didn't work. Anyone have any ideas?

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 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 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?

Answer:Dell T3400 orange blinking light in power button

Blinking Amber power button is Bad Power supply.   Solid Amber power button is Dead motherboard.  T3400 with X38 Express Chipset
