MBP doesn't power on; Power Pads location on MacBook Pro 17" A1229?
This MBP 17" Mid-2007 doesn't power on at all - no signs of life. Battery is good/fully charged. I've tried:
- swapping memory for known good memory
- removing internal HD (and internal HD cable) and booting from external drive
- resetting SMC
- using different power adapter, and booting from only battery or only power adapter.
Power cable light is green, and power flows through to an external drive connected via Firewire.
Internal drive is known good (tested in another Macbook).
The only advance problem I had prior to it not powering on at all: the previous night I'd put it to sleep by closing it, connected to power. The next morning it had shut itself down.
I'm down to likely either a bad logic board, or bad keyboard or keyboard cable.
In order to rule out problems with the keyboard or other devices, I'd like to power on using the power pads on the logic board. But, I can't find them on this model.
Where are the power pads on this model Macbook Pro?
Also, any other suggestions for troubleshooting?
Is this a good question?
