Hello folks, Ive recently been experiencing a few problems with my unibody macbook pro and would love anyones contribution or help on the matter. These problems include: Battery dying when battery percentage is around 20%, no warning etc. Not restoring after battery dies, ie. ram not transfered to hard drive so mac reboots when connect to power source. Occasional freeze after hibernation, even when plugged into power source. Finally when I reboot after the battery dies, it unusually switches from "higher performance" graphics to "better battery life". I cannot understand why this is happening? I have already preformed an SMC reset, PRAM reset and re-calibrated the battery but it hasnt helped and after trolling the forums I am stuck for a possible solution or explanation? I have yet to upgrade to snow leopard and wonder will this have any positive effect on my problems? Any help greatly appreciated folks. Thanks in advance.
