Really sad that my perfectly working Backlit Macintosh Portable M5126 just died. Really strange about the way it died too.
3 weeks ago I got a new battery from alaska360 and zulusci to replace the old harddrive. It was working just fine on battery (fully charged) and turned on and off without any issues. Thought I had some time before I need to have it recapped so I left it in the original suitcase for storage with the battery in it (probably a bad idea) and a brand new 9V.
Well, this week I took it out again to have it recapped and it wouldn't turn on; even with the 2 reset buttons on the side...nothing.
The only times it would turn on is when I try to open the battery bay or when plugging in occasionally and always gave a power management error. The screen and backlight worked fine of course.
Just had it recapped and it's still the same. The board is near perfect with no broken traces so the only thing I can think of now is the power management chip? Could it have died on itself in storage with a battery? I measured that pin 52 A/D filter on the PMGR chip is indeed receiving 5.1-5.3v depending if reset it pressed.
Anyone with diagnostic skills available to help take a look? Happy to pay. Would really hate to just blindly replace the PMGR
