CPU HOT & fans race when battery in, runs normal with battery out
Today it got weirder. So, my battery had bitten the dust 3 or so months ago. I bought a new one today. I took the old one out, and restarted the computer with no battery in it. I used it for an hour and the CPU temp stayed under 60 and the fans at a nice 2000rpm! Was this old battery somehow the problem?
So, I shut down, put the new battery in and within 5 minutes the CPU temp was up to 71 deg and the fans at 3400 and holding.
So, computer on (I hope this is ok), I popped the battery out. INSTANTLY, the temp started dropping and the fans slowing. Within a minute I was back down to a temp of 60 deg and fans at 2002 rpm. Within several minutes I was down to 52 deg for the CPU and 1999 rpm on the fans.
Again ... popper the "new" battery back in within seconds the CPUs temp started going up. Within 1 minute the CPU temp went from 52 deg to 70 deg. And aagin, pop the battery out and the temp drops instantly and dramatically (same behavior using the new and old battery.)
Ideas?!?!?!?
(Note, my last battery failed under mysterious circumstances ... if went from holding 2 hours of charge to only 20 minutes overnight, with the only change being me upgrading from 10.4 to 10.5. (and the battery indicator being totally off. Many many people here are posting these same battery issues...random shutdown when battery shows 80% charge, etc.)
