820-01521 "intermittent crash on battery"

[KC Micro Tronix]

This is a odd one. Don't know where to start. Came in to me with intermittent crashing on battery. "which I really can't duplicate" The battery was just replaced before I got it. Customer said it does not crash when on the AC adapter.

Have you seen this on this board? Are we looking at CPU buck fets here?

Did you test with another (known good) battery?
You can't be sure about the problem, until get the failure.

Battery was good. Totaled the machine. Probably a CPU driver or something. Too intermittent to repair.
