It sound like one of two things has happened.

A - Your LCD panel has gone bad, which will require you to replace it. You can usually find LCD screens on Ebay for a good price. Installing one is not as hard as you may think.

B - The connector that plugs into your notebook motherboard has become dislodged. You can take the facing off of your notebook and check that connector. I've had two Dell notebooks that had the same problem. Over time, the connectors worked themselves loose.

Please be sure and obtain a service manul for your notebook BEFORE attempting to take the facing and keyboard overlay off. It will provide you with detailed instructions on how to do so. If you will give me the exact model number, I may be able to find the service manual for you.

We have a Compaq CQ61 and my son turned it off and back on and the screen is black. We tried the brightness, turning it off and on again and nothing is working


Hi,

You can try the following steps,
  • Turn off the notebook
  • Disconnect the power cable
  • Take out the battery
  • Press the power button for 15 secs (to drain out static electricity)
  • Connect the battery back on the notebook
  • Connect the power cable
  • Turn on the notebook
Note: You may also check if the light on adapter is on (if there is any) and the light where the power cable connects to the notebook is glowing. If the light is not glowing it is the adapter which went back.

Regards,
Shrey

I re-started my toshiba A135 laptop, and the screen went black


There are dozens of possible root causes for your problem I guess.

But exactly the same happened to me in fact on a packard bell laptop. After my son forced it to reset, it didn't start again. Only one led was lit. After a long search I found that the battery had died and this prevented the laptop to start even when the power supply was plugged in.

Try this: remove the battery, connect it to the power supply and restart.

Hope that helps

Dell loptop wont turn on


take out ur batteries, clean the terminals with spirit or light alcohol, then re-insert it. better u use direct power supply but be sure to check that the power is beig supplied and the terminals/sockets are cleaned.
did this helped u. if not, tell me, when u push the power on button of ur notebook, does anything happens, like the fans start spinning or light went on. does the screen turn on or does something appears on the screen?
if nothing is happenng after pressing the power button, then this is a clear case of problem with ur power recieving section of the notebook. go to your pc dealer.

Hp dv9000 will not start up. blue lights are go


you get a black screen right, nothing at all then no bios, no logo, nothing at all?
Do you get any beep codes and if so in what order?
did you try different ram?
First try to plug your laptop to an external monitor. If it works, you screen is bad, if it doesn't you probably need a new motherboard.
