I have two of these
One is a v2. pcb, the other (giving me problems) is a v1. pcb
The issue is with the keyboard.
AT POST, sometimes the mobo will issue a beep or beeps, flash the num, alpha and scroll lock leds and I will lose the keyboard.
Naturally enough I thought this was down to bad caps
Sure enough, albeit the caps did not show bad phy. signs or bad ESR,
I replaced both the CPU I/P and O/P VRM as well as all the 10V 1000uF
caps on the mobo. All the other caps are 470uF or under.
Post recap, the issue still persists.
I tried testing the ESR all of the remaining caps and found four or five
that had suspect ESR in cct. I took them out and tested the ESR again.
This confirmed my suspisions.
Post recap, the issue still persists.
Checked the solder work on the superIO IC - this is good (appears ok).
Any other suggestions from forum members?
