When I boot my Acer laptop, the keyboard is dead. However, if I go directly into Bios, or load the OS from a bootable CD (Acer's Recovery Disks), the keyboard works.
Here's the sequence of events that I tried after a HAL.dll failure.
1) Booted from home-made Recovery CD ... HAL.dll error continued
2) Ordered Acer Recovery CD's
3) Booted from Recovery CD and re-built system. Keyboard and mouse touchpad work during entire installation. System reboots and begins initialization process ... prompts for computer name ... keyboard is dead.
4) F-disked C & D partitions. Created single C partition. Performed item 3 again. Same results.
At this point, I'm very confused. I don't understand why Bios and Windows are using two different methods of retreiving information from the keyboard.
