i have two HP G71 laptops with mobile graphics express 4 chips. I think one had a video driver update pushed to it that may have crashed.
i get a black sceen with a mouse curser. the computer still seems active, but no display. when i first touch the mousepad after a re-boot, the cursor dims.
i have tried (many times each):
ctr-alt-delete - black screen
safe mode - black screen
last know good config - black screen
swapping hard drives - black screen moves with the drive
external monitor, vga and hdmi - black screen
hard reset (no a/c or battery) - black screen
with a boot from repair disk, i get low res VGA mode on the display:
chkdsk/r - no errors
sfc/scannow (offline mode) - no errors except for winpe.bmp
system repair - no errors (reports that OS booted normally)
restore point (only had one) - black screen
i tried a graphics card update on the working laptop, and the screen went black for a few seconds, then came back okay.
thanks
