Greetings all! I just received a Macintosh Portable M5126 and did a complete recap on the logic board. I am able to get it to power on and I get a happy chime but it's stuck in a reboot loop, rebooting and chiming every 3 to 5 seconds. The board has been cleaned in a ultrasonic cleaner. I also triple checked all traces under/around caps and all tested good. I checked the reset pin (pin 10) on CPU and it goes and stays high. Any ideas on what to check? Thanks!!

Thanks for the response. Yes, that's what I have been doing actually. I new, fully charged 6V and 9V battery only.
Oops sorry, I did mean 6V main battery! With what is a power issue, I'd be having a good look around the hybrid module, potentially even desolder it and clean underneath.

Thanks but this is the M5126 backlit version that doesn't use that module.Oops sorry, I did mean 6V main battery! With what is a power issue, I'd be having a good look around the hybrid module, potentially even desolder it and clean underneath.
