Backlights stay lit after laptop powers down - no way to turn off backlights without unpluging

Q: Backlights stay lit after laptop powers down - no way to turn off backlights without unpluging

For the past year or so, the backlights on my laptop (thinkpad x120e) remain lit after I have powered down the laptop. To turn them off I have to unplug the power supply. Then the backlights would remain off. If I remove the battery and power supply (so the laptop is undeniably off) and then plug in the power supply (without a battery) the backlights turn on instantly. And until about two days ago it made no difference whether the battery was preset. As of two days ago, the backlights remain lit even when unplugged as long as the battery present, but they are much dimmer than they are when plugged in. I am not sure why it got worse, the battery never mattered before, and I have searched the web thouroughly seeking a solution numerous times over the past year or so, with absolutely nothing useful (or relevent). I have tried manually turning off the backlights with things like xbacklight or windows gui tools, but when I dim it all the way the picture goes away but the backlights (at least some of them) remain lit. I have even tried using shutting down from multiple different operating systems (windows, linux, etc), just in case one wasn't accomplishing the shutdown fully, but the problem persists. I would like to fix this issue once and for all (and not at a repair shop), so any pointers as to the culprit or what possible mechanisms may be behind this would be welcomed. At this point I have no information with which to start.

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.)

I was shopping a few days ago for LCD monitors and I ran across a new brand called CMD. It's a taiwanese brand that makes LCD screens for other companies. When I walked by this LCD...it was beautiful. It's a 15" screen with a contrast ratio of 500:1 but the best part is that its brightness is 480cd/m2.

I asked the sales person about the monitor and he said that it has 6 backlights, which I thought was strange because don't most have only 4?

I later talked to other people and they all said that I shouldn't buy the LCD with 6 backlights because they could burn out (they were all trying to sell me other monitors by the way). I decided to go to a better source and ask you guys. What's right and what's wrong. Which monitor should I go for? Also, what specs. should I look out for when deciding which is better?

Thanks a ton.

Hi all,

I have a Logitech G110 keyboard, and while it is backlit the colours are limited to several "dark" hues (dark blue, purple, red). Plus I don't use that column of programmable keys on the lefthand side so it's kinda overkill - and the extra width makes things in my sniper's perch quite cramped so I'd like to get a more regular sized keyboard.

Can't find many alternatives though. While I like the looks of the Tron Razer keyboard - the lights are much brighter - it seems to only light up in that light blue colour. Can anyone suggest another keyboard with backlit keys? Main thing I'm looking for is how bright the lighting is.

A:Suggestions for keyboard with backlights

There are tons of keyboard out there. Me my self are using a razer lycosa. Everything comes down to persoanl pereference. Do you want a mechanical keyboard if so what kind of switches. My recommendation is to go to an actual store and ask them for a look at theyr stock and maybe even get a feel of how the buttons work and how they sound.

I just received this monitor from a friend who say that it is broke. They explained to me that a green worm crawled across their screen back and forth from bottom to top eating their pixels until the screen was completely black. Ever since then the screen has not worked. When I plug it in I can faintly make out the picture of my OS and when I hit the menu button on the monitor I can faintly see the menu come up. So I know the screen works. The first time I plugged it in the backlights came on and the picture was perfect but within 5 seconds it went black again and I havn't been able to do that again. Please help me to resolve this issue or tell me if it can be resolved. Thanks.

Hello all..

Last week I had a new motherboard installed on my Asus Q500A laptop.
When I got it back the keyboard backlights no longer worked. This wasn't a problem before I sent it out for repair. Here is what I've done so far to try and fix it:

- Installed eleven different versions of the ATK package. v18, v22, v23, v24,
v25, v28, v29, v30, v31, v33, v34

- Reinstalled keyboard filter drivers

- Reinstalled Intel chipset drivers

- Reinstalled asus express cache and instant key utility

- Downgraded bios from 207 to 205, then back to 207. I don't know what
the bios on my old motherboard is.

- Installed a brand new keyboard. Thought maybe the old one was
somehow damaged when the new motherboard was installed.

I am running Windows 8.1 64bit.

Have I missed anything? What could be causing this?

Just pulled out an old Inspiron 5323. For some reason the computer won't boot past the dell logo. It just goes to a black screen. Attempting to enter the setup or diagnostic utility gives me the same black screen. Tried using an external monitor as well with no luck. Tried a different hard drive. Different ram. Replacing the cmos battery. Unplugging the laptop battery. Nothing. If I unplug the laptop battery I do get a warning at boot telling me there's some issue with the battery but pressing F1/F2 gives me a blank screen again. If I press F12 I get the boot menu but any option I select gives me the same black screen

So my Sony Vaio has decided now to never turn off.
Go to the power button and press shutdown, it shuts down and then once it is finished powering off (all lights go out and everything) it powers its self back up.

Remove the battery and wait 5 minutes, replace the battery it powers back on.

Remove the battery and connect the mains lead, powers on.

Checked settings and I cant see anything that would cause this.
It has been running fine until today, unless it installed an update but I dont see how it can just be an update causing it to just turn on as it wants.
Its not a stuck power key otherwise it would also turn itself off.
It is not just going into hibernation mode, I am trying to properly shut it down, which it does but then just comes back.

Any advice would be great, can only find stuff about unexpected shutdowns not the opposite.

A:Laptop powers itself on and refuses to stay turned off

In Advanced Power options set the Power button to shut off the machine. Then use the power button to boot down. This is to test the button.

Then I would boot to the WinRE disk, then boot down. See if that breaks the reboot cycle.

If not, boot back to WinRE (you can burn this disk from Control Panel / Backups), and run the Command Window. From there type bootrec /rebuildbcd. That might clear any reboot flag if there is one.

A:My Laptop Screen Wont Turn On But It Powers Up

Have you tried connecting an external monitor (how to is in your manual)?

It may well be a component failure like an inverter board since you 'crashed' when it first happened.

When I turn my laptop on, it powers up with the usual sound, then stops making any sound at all after 2-3 secs. The button lights are on but the screen doesn't turn on at all. I've tried removing the battery and powering up with the cable but nothing. Also I've tried connecting to my tv through hdmi which i usually use and still nothing. As a guess, I think it's the motherboard but hopefully it's something more simpler to fix myself. Thanks

A couple of days ago, my laptop started powering off suddenly. One second it's on, and the next, no hard drive activity, no screen, no nothing. This happens in an instant and without warning (no blue screen). Starting yesterday, the problem got worse. After the power cut out, I would have trouble starting the computer up again. Sometimes it worked, sometimes it didn't. When it did work, I sometimes got as far as the Windows login screen. When I hit a key to begin typing my password (or swiped my finger on the fingerprint scanner), the power cut out. Today, it seems to have gotten even worse. Sometimes the startup process doesn't even get as far as the Windows login. A couple of times today, I pushed Power, got the the Windows Startup Error screen, selected to resume Windows as normal, and bam! Power's off.

Now, this gets even more mysterious. Sometimes I push the power button (after one of these instances), and nothing happens. Sometimes I push the power button, and the power light comes on, and then the fan, but no hard drive activity. Dead. Sometimes the computer won't start up at all unless I remove the battery, pull the plug, wait a few seconds, and then try again.

Even stranger... I have the computer on right now. It's been on for 5 hours, and it's working fine. I'm afraid to turn it off or put it to sleep, because I know it might not start up again.

HELP!! I have a laptop that will turn on enough to boot to the Win XP screen, then shuts off. Once it shuts off, it will not turn back on until about an hour or so later. There's a little blue light in the front that will blink like it's in hibernation, but it refuses to turn back on! Oh yeah, we checked the power cord (fine) and also the battery (also fine) Any ideas??:


A:Laptop will turn on briefly, shut off and stay off...

Overheating would cause this ...if the heatsink is plugged up with dust and then the CPU would overheat and would not startup until it had cooled down enough
Also make sure you hear the fan spinning on startup

This happened three times already. I noticed this occures a few minutes after I unplug the power. Also the trackpad stops working a minute or two before I get the BSOD. I checked the system history via the My Dell program and it says that the BSOD was caused by the "PCI Express Root Complex" driver. I don't know how to fix the problem. I already updated all my drivers. I added the SF diagnostic tool zip to the attachments. Any help would be much appreciated.

I am having a strange problem that I can't figure out what is going on. After my computer is in Windows for several minutes, the screen will go black and say No Signal, the fan on the motherboard turns off but the Power supply fan keeps going. The LED for the HDD and DVD stay lit solid.

I have tried a new power supply but still same problem. I have replaced the memory and still have the same problem. I have ran diagnostics on the Hard drive and it passes. I have reloaded Windows for the heck of it and still have the same problem. However, if I leave the computer in the setup screen instead of booting into Windows, it stays on all day long with no problems.

Any ideas? I am so lost.

My friend's hp Pavillion dv6000 is currently under my care. For sometime, she says, the laptop would get caught in a loop by which the power for the laptop would come on momentarily, then power down. Then power up, then power down. Etc. Nothing displayed. No POST. No nuthin'. But if one depresses Ctrl + Alt + Del it stays powered on, but do nothing else until it powers down and stays off after a few minutes of this suspended state. (Note we haven't even gotten to POST ever, so no boot screen, Vista, Safe Mode, etc.)

I stripped it down--removing all memory modules, the hard drive (drive runs, contents are intact), and the optical drive. Upon start up the same routine took place and there were no beep codes!

I followed the instructions for resetting the BIOS (Pull battery. Tested it: 3VDC registering).

I've done this with battery only, power adapter only, and both. I get the same results regardless.

So the question: Is it dead? My opinion: Yep. The anomaly that keeps me wondering (and this may be just nothing): Why should Ctrl + Alt + Del do anything?

Maybe just answer the first question.

So I've looked around for possible solutions to my problem.

My problem is I turn on my PC and I see a green led for my Motherboard power. The fans spin for just a second then stop, and no boot.

I've disconnected every component except the heatsink, cpu and fan.

I've tried resetting the CMOS by changing the jumper settings. No good.

I've tried switching the memory around. Nothing.

I've now taken the motherboard battery out and will re-insert it after this post is finished.

If that doesn't work I fear I'm running out of options.

I tried the PSU in another PC and it was fine. So I know it's not the PSU. I tried the OTHER PCs ORIGINAL PSU and that did gave the same problem.

I've read up on a couple of articles about shorting out the motherboard or power supply or something as a solution.

Is this true? It sounds more destructive than creative.

If anyone has any advice or suggestions I would really appreciate it.

This PC is extremely new. Literally half a year old. It has a BFG 850w PSU, an ASUS M8 Motherboard w/ an Athlon Dual Core Phenom 3.2GHz

It has built in SLI with two Nvidia GTX 260s

Two 1gb HDDs

it has about 5 fans including two graphics card fans.

For the last few days I have had a problem where my McAfee firewall won't turn on or stay on. I did some research on this and saw that it was an issue other people were having related to malware.

I did a full system scan with McAfee, and nothing was found. I also did a full system scan with Malwarebytes, and that turned up a few culprits which it removed, but the problem remains. If I open up McAfee and go to the firewall and click "turn on", it immediately clicks itself back off regardless.

Then I tried turning on the Windows firewall, and was unable to do that either. I actually got an error message that popped up and said it was unable to change some of my settings.

Here are the logs, with GMER, I was only able to select services, registry and files. Everything above that was not available to be checked or not.

So working on my stepmom's laptop and she said she couldn't get the computer to turn on any longer.  I found if I held the power button the light on the right side would blink orange and white alternating.  I wasn't able to precisely figure out what that meant through google for this particular model, but saw on some other models it was a sign of a dead/dying battery.  So I started with a battery replacement.  At this point the battery didn't signify that it was charging at all and when I pressed the power button with the AC adapter plugged in the light on the right would flash once and then nothing.  If I held the power button down the light on the right would flash until released.  I tried the Fn + PWR and nothing other than the right light blinking once and then turning off.  So next I bought a new Dell AC power/cable charger (I'm not sure the correct term).  Same results. 
Next I bought the DC power input jack replacement part and put that in.  Same results.
I bought replacement RAM.  Same results. 
Today I tore the entire thing down cleaned it up and there was very little dust throughout the heat sink assembly.  Cleaned up the factory thermal compound and put some Noctua thermal paste down in it's place.  I also took the opportunity to change the CMOS battery out with an Energizer 2032 battery.  When I put it all back together I plugged it in with the new RAM, battery, and ...

Hello there,

I have an one year-old ASUS K53S Laptop, Windows 7 Home Premium, 6GB Ram and 500HDD.

At the beginning, my battery lasted >3 hours in Balanced power mode (which is the one I alway use) and now due to regular use it last about 2 hours.

Everything normal until here. About 2 months ago, i started playing this game in full screen with the battery on and it last about 30-40 minutes until it reached the low battery warning (11% left). I would then plug the power on and resume the game, charging the battery as well.

After a few weeks, the warning stopped appearing in the desktop and the computer automatically hibernated (5% left) with the game still on. So i plugged the ac power on and resumed the game right away.

This kept happening from that moment on: every time i played the game it would reach 5% battery left and hibernate for itself, whereas it should appear the low battery warning at 11% left where I would plug in the ac power and charge the battery without going into hibernation.

On top of that, my sister kept stealing my ac charger for charging her Toshiba Satellite as she often forgets her own charger at her workplace!

Now, at the present day, when the battery reaches about 15-20% left, the laptop power off unexpectedly, as if I had pull the battery off of the laptop.

It must be from all those time it would reach 5% left, with the game still on, that "tired" the battery and now it won't even last further than 20% left...

A:Solved: Unpluging IDE cables/ cd rom and DVD drives

If the optical drives are on the same IDE cable as the hard drive then you need to make sure the hard drive is jumpered as a SINGLE MASTER and not CABLE SELECT or MASTER WITH SLAVE PRESENT. Also the hard drive should be connected at the END of an 80 wire IDE cable. Then in the BIOS setup set all the drives to AUTO DETECT rather then setting any of the drives to CD-ROM/DVD-ROM.

But why are you disconnecting the drives?

I have a 4 GB simpeltech USB disk drive. When I connect it to a usb port it is recognized and works fine. When I disconnect it my PC always shuts down. Is there any way to avoid the shutdown?

A:unpluging simpletech 4GB USB drive causes shutdown

Give this a try, sometimes corrupted parameters in the registry will cause that. This will remove everything and allow Windows to rediscover the hardware when it reboots.

Create a file with NOTEPAD containing the following lines and save it as FIX.REG
-------------------------- cut after this line --------------------------------

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment]

-------------------------- cut before this line --------------------------------

Double click on FIX.REG and say yes to the Merge Into Registry question.

Unplug ALL USB devices.
Open Device Manager.
View, Show Hidden Devices.
Uninstall all devices under USB Controllers.
Uninstall all devices under Disk Drives that you know are not present.
Uninstall all devices under Storage Volumes. Say no to any reboot prompts until you are finished. Also, if a Storage Volume doesn't uninstall, ignore it and move to the next one.
If you have a yellow ? with unknown devices, uninstall all of the entries there as well.

When this is done, reboot TWICE.

Reconnect the USB devices and see if they're recognized properly.

I have a Gateway model MD2614U laptop os Win7 home 32bit. When I unplug the headphones to use the internal speakers sometimes the laptop will switch over and sometimes it won't. When it won't switch over. I open the volumes control window and I can see the green bar going up and down with the audio source but there is no sound coming out. I have to end up closing down the program that is producing the sound then the switch over will complete and I restart the program. I also have the same problem when I plug the headphones back in, again no sound from the headphones even though I see the green bar moving. Also some programs that send and receive audio over the internet will lock up when I unplug or plug in ether the headphones and or the microphone. Does anyone have any ideas on this problem?

A:re a problem with unpluging and pluging in the headphones

right click the speaker icon on the taskbar and select playback devices,
when you see the headphones with the green bar, try setting them as default .
(click on them to highlight them and then click set default then click apply then OK)

hopefully when you unplug them your sound will revert back.

I have a Compaq Armada 700 and I'm running Windows 2000 on it. I recently replaced the original power supply a few months ago and lately, the computer just turns off in the middle of me using it. Sometimes, it will power back on, all by itself and then turn off again. There are also times that it will freeze before it turns off, and times that it just stays frozen until I have to unplug it to restart, because none of the keys will work. Could this be a virus that is unnoticed by my Symantec Antivirus and my Spybot? If not, what is it? I've even gone to a site that detects virus' and haven't found anything. Any help you can give would be appreciated.

I have an IBM Thinkpad i Series 1400 laptop. After about 15 minutes of being on it just powers off. Even though I have it plugged into A/C power it doesn't reflect that on the display. It shows the pic of the power cord with a lightening bolt threw it and says that the battery is 0% charged. Even though I have let it charge for hours. If the battery is dead can I not use it with the adapter???? I looked thru my handbook and in another section entitled "computer doesn't turn off" that they advise to switch to a full charged battery pack or A/C power". This leads me to believe that you can just use A/C power. Am I wrong? Just very frustrating considering that I have a PC that isn't running either that I have had asked for advice on here.

After I unplugged lenovo android phone, windows freeze immediately. All I could is reboot.

In event viewer all I found is:
The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.

What cause this?

Hi, My Lenovo N200 laptop has recently started powering off during the boot process.

This happens consistently when the windows xp "loading screen" is displayed with the green loading bar.

I can get passed this stage in the boot if i turn on laptop and enter BIOS for a couple of minutes.

I have also noticed that a fan is audible as "whirring up" when the problem occurs but is not audible when xp boots normally.

I really dont know what the issue is, any assistance would be much appreciated. Thank you.

A:Laptop powers off during xp boot

It might be dusty and overheating or this could be a thermal shutdown. The CPU may be getting to hot. You can used a compressed air or vacuum it. Then try running it on a cooling mat.

Hope this helps.. Good luck

Allright, I have serached the forums and have found some stuff that it could be, but I don't think it's anyone of those yet.

I have a Gateway Solo 1450 which had been working fine since I got it a few weeks ago. Used obviously. Right from the get go, I have had problems with the unit shutting down by itself while running what I might call "labor intensive" applications. Examples: I was playing a game off a CD-Rom and it shut down, I was running Spybot Search and Destroy and it shut down, I was playing SNES emulator and it shut down.

Now, I believe this may be an oerheating problem, case in point, after having the unit shut down while running Spybot, I rebooted and reran Spybot and it made it through. I don't think I notice the fan working or not, so that may be a big thing. I have the vent port in the back that is open, so air should be getting in, however, on this laptop, there is a larger vent on the bottom, which is retarded since there are no legs or whatever to prop up the back of the laptop.

I found on Gateway's website a Bios upgrade which is supposed to increase the fan frequency. I followed the directions, but I can't seem to find the orginal Bios, which I'd like to copy since the instructions are telling me to. It says that they should be at c:\CABS\9522082. But when i go to c:\cabs, all i have is a folder called 1450 with all of the drivers in it and two refistry files. So, i'm not sure what to do. i'm thinkin... Read more

A:Laptop powers turns off by itself

I have a 18 month old Sony Vaio Laptop which, last night, decided to give up the ghost.

When I power it up it turns on, I hear the hard drive come on an the fan start up. I even get a flash or two from the processor light. But then nothing the screens stay black and other than the power light, the fan and the hard drive there are no signs of life.

Any ideas would be gratefully recieved.

This is what I have tried so far.

1) Initially I thought that it was the screen but when I attach it to an external monitor the problem persits. Also if it was just the monitor and the system was booting correctly the NUM and CAPS lock lights would come up eventually, which they don't.

2)As I can hear hear the disc drive checking for discs I Inserted Vista disc in an attempt to boot from CD. No luck!

3)Removed battery, left for 20 minutes or so. I then inserted the power cable and held down power button for 1 minute. Apparantly this should initiate a hard reset, although I'm unsure if this is true or not but I thought it was worth a shot at this point.

4)Now i'm desperate. I open the beast up and check it's not been bathed by one of the kids. I also checked for any obvious signs of damage or cables having worked their way free. All seems fine.

5) Booted whilst holding function key and F10

6) Suspended it in a nice hot cup of tea! unfortunatley no finite amounts of improbaility were produced. Nor did it boot up.
