Unexpected power behavior (sleep, shutdowns) after repair

I recently sent my MacBook Pro (Early 2008, 15") into a computer shop to have the right speaker replaced. Shortly afterwards, the machine began exhibiting unusual behavior; it started unexpectedly sleeping or shutting down while I was using it.

(Note: My MBP battery is perma-drained almost completely, so prior to sending the computer in, the computer might unexpectedly shut down if running solely on battery.)

I reset the SMC and thought nothing of it, until the mac shut down unexpectedly again, almost 24 hours exactly after the SMC was reset. I then decided to run the Apple Hardware Test.

It froze on 'testing logic board'. Twice.

I have since reset the SMC again, and am unsure if problems will continue. If these power issues do recur, what should I do?

Notes:

• I installed smcFanControl after the first shutdown. Whatever's going on, it doesn't appear to be the result of an overheat.

• Before you ask, I am not under an Apple warranty.

MacBook Pro, Mac OS X (10.6.8)

The problems have continued, albeit very intermittently. I was able to get the system log after one unexpected sleep. Here's what it said:

"Low Power Sleep"? On AC power, with the battery fully charged? I suspect something's up with the power management system, but I don't know enough to be sure either way. Anyone have any ideas?
