This is consistent with the problem I have had with my TP750 and batteries that are 2yrs old (1 yr use each). The 750 (dunno about the other models) would power cycle the batteries in the top 10% over and over again if you used it with the AC adaptor and the batt in by letting the battery wear down to the 90% mark and then charging it again. Unsuprisingly, it destroys the battery. I bought a quick charger/conditioner with the hope that it could deal with this problem, but they appear to be toast. Some people have reported success in getting IBM to replace them since it's a fault in the charging mechanism, not the batt. There are third party battery sources that you can buy a 750 batt for about, oh, $120 or so. The only oneline one I know off the top of my head is www.warrior.com. They don't seem to have prices online, though. Oh, by the way - I see they have 2.1G slimheight drives apparently with caddy for $950.
