Re: the driver usage in onitor is disable
There are a number of issues that causes this to happen.firstly check to make sure the machine is getting power, if it is and it all lights up turn the machine off remove the memory modules (memory is located on the underside of the machine) get a standard eraser and clean the brass pins with the rubber eraser, put the memory modules back in and that usually works. If you still have problems with the monitor then chances are its the inverter (backlight) or processor

Hello, Try connecting an external monitor to the computer and check if the external monitor displays the same thing. If the external monitor is fine then you would need to fix the LCD of your laptop. or have it replaced. If the external monitor displays the same thing, then you would need to update the video driver in your computer. You can use RadarSync to automatically update the drivers. David
Suggest you connect an external vga monitor to see if that screen also becomes black. If it does, then the problem is not likely to be the notebook's screen itself but something that is driving it. So it may be a driver problem or possibly a Vista screen saver effect. So for starters, you could try disabling the screen saver.
Try booting into safe mode. That will disable all drivers and use generic windows drivers to send commands to the devices. If that still doesnt work, id say that there is a problem with your OS installation. Backup your files using an external harddrive enclosure and reinstall the OS.
This may be a battery power monitor issue. Try disabling the "Mircosoft ACPI- Compliant Control Method Battery" device. This is located in Control Panel-->System-->Hardware Tab-->Device Manager-->Batteries. Had similar problem with 2 Acer Aspire series laptops (diff models). 2 and 3 year old. Original batteries (both still hold charges for 1.5 hrs of normal usage). Running WinXP, one with SP2 and other had SP3. Both came in the last month with slow jerky TPAD function and nearly non responsive keyboard access. Checked the usual; virus, spyware, hijacking, driver conflict etc. Cloned drive and factory installed..still same problem with kb & mouse. However an external USB keyboard and mouse functioned normally (no lag). Noticed with Battery removed kb & mouse was normal. Finally found disabling ACPI control battery device resolved this issue while allowing laptop to run on either battery or AC.
Try using a different monitor if you have one available, or disconnect the monitor from the computer and then turn it on. If you see a logo or color bar or message saying no signal, then your monitor is OK and you should take a look at your video card.
If you suspect your video card, there is very little you can do with a no video situation. but one thing you can do is to remove the video card completely and wait for a few minutes. then put it back in and try to start your computer. This is just in case you have corrupted video memory keeping it from functioning. otherwise, replace the card.
In the case that your video is built into you computer, buy a new card and disable the onboard video in the BIOS. That will take some browsing in the BIOS setup, but it shold be fairly easy to find. once it is disabled, the new card will be able to function and you should be ok from there. Otherwise, it's motherboard replacement time.
