    black screen - no way out?

      <Does anyone know of a way to run a intel mobile graphics express 4 update from a repair mode command prompt?>

       

      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.
