try using the usb mouse then go into control panel>system>hardware>device manager. Click on the +sign next to touch pad or pointing devices and right click on touchpad, then click on uninstall. Reboot the computer, unplug the usb mouse and the touchpad should be picked up as new hardware and be re-installed.

there is a inverter in LCd that makes your lcd bright white shine. when it breaks down you see black screen. something happens on lcd you cant see clearly you should go to service and need to be changed INVERTER.

It is the backlight! That laptop uses a fluorescent lamp. It is bad.
If you look carefully at the screen, you will see the Windows desktop (or whatebver you are running). It just needs to be lit up.... from the back. Tel them to replace the LCd screen or replace the lamp.
Hope this helps!

Testimonial: "Has happened a couple dozen times. Next time the screen blacks out I will look carefully to notice if the desktop is showing. THX"
