Power button does not work any more, keyboard and trackpad OK

Dear all,

I have MacBook White mid 2007, Core 2 Duo and till last week it worked with no problem although battery died almost 2 years ago.

I just have upgraded it to Snow Leopard for my friend and next day we went skiing. When we got there MacBook wouldn't power up. Yesterday I took it apart and managed to power it up with screwdriver (touching pins) on upper case connector on logic board. Then I attached upper case when MacBook was booting. All keys and trackpad worked with no problem.

I assume only Power button has died. Could there be way to get and replace only Power button?

Thank you for your help and time,

pe3c

If it's only a power button issue: sadly, you can't. You may try cleaning around with some isopropylic alchol, maybe there's some grime around, but the upper case is a solid lump of plastic and circuitry that prevents you from having any work done.

Thus, I'd try to see what happens with a new upper case cable. Failing that, I'd try with a replacement upper case...

Hi there,

during Easter I found time and took my MacBook a part and tried to clean it as proposed, but there was no improvement. Power button still doesn't works.

I noticed funny thing. If Caps lock and/or Num lock is enabled (LED on key) and Power button is pressed both LEDs blink. Could this mean something?

Thanks for the help.

Nothing that comes to me in mind. Save that there could be some short-circuit affecting the power button.

Sadly, it can't be fixed, as I told....
