I posted an email similar to this months ago, but no one had been really using the list then, so I will repost. I recently decided to start using my Titanium 400Mhz Powerbook. Interestingly, I got a new battery, and the computer will still not turn on even after the battery is charged. It will turn on when the power plug is in, with the battery in as well. I actually did manage to calibrate it once, as it stayed on after I pulled the plug. Sometimes, however, it does turn on after it is unplugged even with a charged battery in. Also, it doesn't keep the date and time after a restart. So far, I have replaced the PRAM battery and the PMU. Any ideas? -- Your friends confine you in their worlds, one by one, a string of pearls.
