Dead CMOS Battery - NEC Powermate portable

Wasn't worth the trouble really as I had 6 of the same type board at the
time so I stripped the keyboard bios chip (to replace a bad one on another
exact type) and chucked it in the scrap bin for the recycler. Not even sure
if it would have worked, the stuff from the battery worked pretty quick. It
did eat off some of the PC board trace IIRC where it wasn't varnished.
