Problems with new logic board. I think

[MattJ11]

So, i had to get a new logic board fitted because of a broken USB port.

Now all of a sudden the computer keeps shutting its self down and instantly restarting randomly. Sometimes with the please hold down the power button message and sometimes not.

This only really happens when on battery power.

What do i do? I only have a bout a month of warranty left.

I have a mid 2007 MacBook. 2.16Ghz, 1gig RAM, 10.5.3

Thanks

How long ago was it replaced? Any warranty work done by Apple has a 90 day warranty or the rest of the warranty (whether one year or three), whichever is longer. Regardless, I'd try and get it sorted as quickly as possible. If it was perfect before (save for the USB port) I'd say they should be perfectly understanding.
