Hi all - I picked up a Mac Portable and recapped the main board and am having an issue -- a story as old as time itself!
The Portable wakes from sleep just fine and will boot, but as soon as the Finder comes up, I ALWAYS get the "No battery reserve power remains...Good Night." and then it goes back to sleep.
The Portable is plugged in with a real (beige) Portable power adapter which is outputting 7.5V. The 6V lead acid battery is charging just fine and holding a charge well. The 9V battery is brand new and giving me 9V.
So I'm wondering if there is a broken trace in the battery/power sense circuit? I've been looking at the Portable schematics on the "HYBRID / POWER SUPPLY" diagram, and buzzing out the circuit and did find (and fixed) a broken trace from C17(+) to C110 -- the trace appears to run under the hybrid which is why I didn't see it when recapping. But that didn't help.
Is there an area I should focus on given the symptom above? I'm hoping it's not the hybrid itself, but any hints would be appreciated.
Thanks!
