Hi

If you can get into the BIOS setup of your machine, do you notice the same problem? If so, it might have something to do with the hardware. Otherwise it might be a driver issue of some sorts? Perhaps also try disconnecting the keyboard altogether. It is possible that the keyboard backlight is driven by the same power supply as the LCD backlight and a shorted keyboard backlight module is causing the ppowersupply to malfunction.
