Thread: MBP A1226 won't power on
09-07-2013, 04:38 PM #1MBP A1226 won't power on
Fixing a MacBook Pro A1226 that was replaced/repaired under warranty a year ago for the (big surprise) NVidia GPU failure. It's been working flawlessly, aside from getting really hot. I replaced the thermal compound several months ago and more recently helped the owner upgrade his RAM.
About a week ago, it decided not to turn on. I managed to get it working again after applying pressure on the keyboard, thinking the cable might have come loose. Eventually it started and was working fairly consistently, but a few days later he called me back and couldn't get it to start again. I removed the top case and inspected for loose cables, but everything looks clean and kosher. It doesn't even give me a blinking power LED to indicat error, but the power adapter LED goes on and off.

What can happen is the SATA cable with heat and over time becomes brittle. Removing the drive can cause fractures which results in very spasmodic operation.Hang on to those original install discs like grim death! Using OS X.7 or later make a bootable USB thumb drive before running Installer!
