If you are running windows, you might have to re-install your operating system, if that doesn't work, you might be having a bad system board and or memory.

Toshiba satellite laptop won't wake up from hibernation even after holding power botton down?!


If pressing down and holding the restart/start button doesn't wake it up you might try Control + ALT + DELETE keys (together) - that will reboot it though. And if that won't work then you might have to pull the battery to reset it.

It seems that some laptops have a problem with vista and sleep mode, in particular, and sometimes hibernate too. You can try going under POWER OPTIONS under Control Panel and setting everything back to default, saving it, then resetting it again. Also it's best to avoid using sleep mode if possible to avoid problems.

If the problem developed after a recent install or updating you may need to go to an older store point to fix the problem. Personally, I just avoid using these settings as much as possible and use regular shut down and a screen saver for times when I need to step away from laptop for short periods of time.

Hi i have an msi u130 and i got a problem when i turn on the minilap shows a black screen and the led of the little moon its ON but doesnt work what can i do? please help me


The moon icon usually indicates that your machine is in SLEEP mode. Try closing and opening the screen lid. If not, there might be a problem with your laptop waking up from sleep mode. Try holding the power button. This will turn it off. Turn it on again by pressing the power button once more. Hope this helps! Have a nice day.

Backlight wont turn on I have a MC218


If you have a very dim display, or no backlight it could be due to a few things. A loose LCD cable could cause the problem, a very basic way to test this would be to apply pressure to various parts of the laptop case and screen bezel, also move the screen and see if a backlight ever powers on. If you are comfortable opening your laptop to check connections then do so. A faulty cable is also a possibility. Sometimes it is a software issue, try turning your display brightness up to max, does the backlight illuminate when in BIOS? If so it is a software problem. Finally it could be a failed LCD inverter, this is a bit of hardware usually separate from the LCD although is sometimes built onto it. These are generally easy and reasonably cheap to replace.<br /> <span style="font-size:12.0pt;font-family:&quot;Times New Roman&quot;,&quot;serif&quot;; mso-fareast-font-family:&quot;Times New Roman&quot;;color:black;mso-fareast-language: EN-GB">Hope this helps,</span><br /> <span style="font-size:12.0pt;font-family:&quot;Times New Roman&quot;,&quot;serif&quot;; mso-fareast-font-family:&quot;Times New Roman&quot;;color:black;mso-fareast-language: EN-GB"><a href="http://www.putercare.com/">www.PuterCare.com</a></span><br />

Dell XPS M1330 Backlight Problems


Really does sound like a backlight problem. They usually don't cost much and are easy to replace if you are good with a screwdriver.

My brightness control does not work just turned on and can not hardly see anything it is up and running what now


Have you tested it with an external monitor?

I would say you either have a damaged inverter board or screen baclight lamp. Usually the inverter board fails in one of the following ways:

1. When you turn on the laptop, the screen lights up for a short period of time and then goes dark. You still can see an image but it is very dark, almost invisible and definitely not usable. When you restart the laptop, the screen lights up and then goes dark again. The laptop works fine with an external monitor.
2. Your laptop turns on but the screen remains dark all the time. You still can see a very dim image outline. The laptop works fine with an external monitor.
3. The laptop screen works fine for hours or even days, but sometimes it goes very dark as it mentioned above. When you restart the laptop, the screen works fine again.

Inverter failure symptoms are very similar to backlight lamp failure symptoms and in most cases you cannot tell which one is causing the problem until you replace either the inverter board or the backlight lamp. From my personal experience, inverter boards fail more often than backlight lamps. If you have to guess, replace the inverter first.

Toshiba L300 screen flickers and backlight


Maybe is the backlight power cable cut. Try with the laptop in power on mode oppening VERY SLOWLY the screen to see if at a certain potition it works fine. Open it all the way up sometimes to check it. If thre is a potition that it works, it's the cable as I mentioned.

Screen dim HP pavilion dv1000


The lid actuator switch may not be working correctly. It's a small switch above the keyboard and led's on either the right or left side. Try pressing it 2 or 3 times to see if the display starts working correctly again. If so, it will need to be replaced.

If that doesn't work, you can also turn it on with the ac adapter plugged in. After it boots, press the power button and hold it in until it shuts off and then turn it on again and see if the display has returned to normal.

If neither of these options work, your laptop may need to have the backlight replaced.

HP pavilion notebook screen turns black after flickering


You most likely have a defective screen - a defective inverter or a CCFL lamp or simply the video cable needs reseating. After reseating the video cable and the problem is still there then :-
To determine if you have a LCD screen or video card problem, read this and follow the instructions.

Defective CCFL backlight, it may have the following symptom:

  • Screen flashs on red/pink and off.
  • Picture stays on in red and slowly be come normal.
  • Picture flickering with dim display or appear black.
  • Picture flickering on and off.
All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp

Connect an external monitor to your laptop and power it up, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight.

Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

T43P LCD keeps going dark


I think you are having problem with backlight. The concept of laptop is that if there is problem with backlight then it will try to shut it down(shut the light down).If you restart your laptop ,that mean you turn the light on again...after that if its blink or something wrong then again your system will try to shut it down to prevent other part get spoil.

What you have to do is..
1.problem from backlight replace backlight
2.problem from inverter replace inverter
3.problem from motherchip...repair motherboard.
