Hi fam. Got a HP DV 5 1000us with a weird symptom.
Gives checksum error at boot but locks the keyboard. Says to press F1 to load defaults but won't take input. Tested keyboard pins with scope and ESC, F1, F10, etc work fine.
Displays the 1st screen (HP logo just fine). Then the bad checksum message appears, with lines on screen, tho). Tried to recover BIOS with win+F. No good. New battery didn't help. Tried 2 spare key boards.
Anybody experienced the same thing?
I was thinking the lines may be related to something else?
