Purchased a Gigabyte motherboard (GA-78LMT-USB3) with a new computer about a week ago. The keyboard is a Unicomp 101-key PS/2 keyboard, which is what I am using to type this question (i.e., the keyboard works).
Upon booting the new computer all keyboard LEDs flash. The computer is unresponsive to any keystrokes (i.e., I cannot enter the BIOS, issue a three-fingered salute, or toggle the lock keys). Effectively, the keyboard is dead.
Tried using a USB-to-PS/2 adapter, but the problem persists. Interestingly, the USB port seems to give the keyboard more power, as the LEDs flash brightly when plugged into the USB port (full power) but dimly when in the PS/2 port (low power).
I wanted to try a KVM switch, but the maximum resolution for KVMs (immediately available) is 2048x, which is shy of the 2560x that I use.
A different keyboard for new computer is responsive.
- Is the BIOS buggy?
- Has anyone else experienced such an issue with Unicomp (or 101-key, PS/2) keyboards?
- How would you resolve the problem?
