Hey All, I just got a refurb MBP 2.5 ghz with 512VRAM. I am having some issues with the battery and sleep. Often times the computer will stop recognizing that there is a battery, even when it is charged (black X appears in battery indicator). Furthermore, when i put the computer to sleep (on battery power) the sleep light will turn off after about 30 seconds and sure enough the computer has lost power and turned itself off. The battery works well when unplugged and lasts for 4 hours or more... it's just sometimes when its plugged in the battery isnt recognized (its powers of if you unplug the magsafe during these times) and it wont sleep while on battery power. I have tried re-seating the battery, calibrating the battery, and resetting the SMC. I have the latest software updates including battery update 1.3. I'd greatly appreciate any help or experience you might be able to share. From the searching Ive done it seems like taking it to an applestore and having them replace the battery would be the solution, however the applestore is in Vancouver which is a few hours and an 120$ ferry ride away. Thanks!
