I'm currently working on a Mac Portable, backlit. Its been cleaned, recapped, fresh battery installed, w/ SCSI2SD. System 7.1 installs fine, but as soon as it booted the first time after install, I get the message:
"No battery reserve power remains. The Macintosh will go to sleep within 10 seconds to preserve the contents of memory. Good Night."
And then it sleeps. Waking it back up just gives the same message, and it cycles again. Booting a System 6.0.8 floppy works fine, as I assume it does not monitor the battery.
The battery is charging correctly, showing ~6.2v alone, and ~7.3v if the AC adapter is connected. I have also tried a bench supply @ 6.5v to eliminate the battery being part of the equation.
I haven't torn it down again just yet. I dug around and saw some older posts mentioning diagnosing the hybrid chip for a somewhat different, but related issue.
Is the hybrid where I should start? Any additional tips?
