MacBook Pro 17" Models A1151 A1212 A1229 and A1261: MBP doesn't power on; Power Pads location on MacBook Pro 17" A1229?

Thu, 02 Feb 2012 01:55:00 -0700

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?

Apple MacBook MC207LLA 13.3-Inch Laptop 2009: How to find the power pads

Wed, 19 Dec 2012 08:34:03 -0700

I have a Apple MacBook MC207LLA 13.3-Inch Laptop 2009 (Model - A1342). I have read others, watch videos but nobody has the same back that I do.

I am trying to find the power pads so that I can start my MacBook without the keyboard connected.

The reason is that some water was spilled on the MacBook, and the keyboard doesn't function well anymore. It now types 2 keys at once and boots in safe mood (assuming because of the Shift key automatically being used). And also the Mac at times runs slows when trying to minimize an application and banner ads on website automatically reloads constantly (assuming again because of the keys).

A external keyboard/mouse works perfect, however I'm hoping that my unplugging the internal keyboard cable that the MacBook will go back to running 100% smooth. If it does then I'll buy a new trackpad with top case so that I don't have to use any external devices. But since they only sell the trackpads on eBay, I didn't want to buy it before I tried my method first...otherwise I'll be stuck with a trackpad I don't need.
