I recently had my MacBook repaired because it wouldn't boot. They replaced the motherboard and the "Battery connector", whatever that is. Got it back the day before yesterday, but after 6 hours or so it gave me a kernel trap. Thinking it a coincidence, I rebooted, started playing a song in iTunes, and got a new kernel trap before the song had played through. It happened again. And again. Then I rebooted again, and I just got "the chime" and three beeps. Great. It's the third-party RAM, I thought. However, based on something written in the report from the service place, I tried booting with the battery disconnected, and it booted fine. No kernel trap. Ran a RAM test (Rember, graphical interface for memtest), no problems. Turned off, attached battery, booted, kernel trap within 5 minutes. Took battery out, booted, ran RAM test for 12 hours. It works, strange. Sent email to service place suggesting there's something wrong with connection between battery and mobo. They apologize and order a new battery from Apple (yeah, uhm, don't ask me).
I've been running without the battery now for many hours, and had no problems until this morning when I suddenly got a kernel trap out of the blue. Rebooted, grey screen three beeps, nothing happens. Turn it off, pace around the room annoyed for a couple minutes, turned it on, it runs... still running. Anyway, this is not a good sign, and from googling I've learned that this error code can either mean bad RAM or bad motherboard. They might have replaced my broken mobo with a dud, which is what I'm actually hoping is the problem. This is because since RAM is third-party (literally the cheapest 1 GB 667 MHz SODIMMs I could find) I'm worried that if they find out it's defective they'll charge me for the inspection. Thing is it worked without problems from the day after I bought my MacBook in early September until my motherboard gave up... hmf... so I want to find out whether it's the RAM or mobo before sending it in to them.
Anyway, the reason I'm posting this is because there were indeed some errors when I ran Rember. Posting the log and hoping there's someone here who can tell me if these are significant or within what can be expected, or even tell me to run a different test. Thanks!
