Back in October I bit the bullet and finally made the switch back to Apple with a Refurb MBP. Then 2 weeks ago it suffered hard drive failure. I took it in to the Genius Bar and they replaced it. I wasn't so happy about the failure, but the customer service was great. But now I'm noticing that the MBP is no longer charging consistently. Sometimes I've got the green/amber light and I'm running fine...sometimes it just switches itself to battery mode with no light. Nothing wrong with the pins, the cable, the plug. I tried resetting the SMC, but that hasn't helped at all. Is there any reason replacing the hard drive would have done this? Anything else I could try to fix it? The nearest Apple Store is 2 hours away, I'm not too thrilled with the idea of having to go out there this weekend again.
