Something I have noticed on my Armada is that aftermarket batteries are very variable in quality. I bought a pair, so I could put one in the CD drive slot, and one in the normal slot, one lasted a year or two, the other failed totally within weeks. The both gave symptoms as described when they failed, with the bonus that one generated a BIOS error message saying the battery was faulty. -- Tciao for Now! John.
