I just got a MBP refurb off ebay about 2 weeks ago. It is the latest base model with the multitouch, 2.4ghz, 200gb, 2gb ram, and superdrive. I used a macbook before this, so I am familiar with the OS and consider myself somewhat mac savvy. However, since I bought it I have been having many weird issues: -(At least) two programs were already installed on the machine: insomniax and Opera, neither of which I installed myself. When I opened up the computer (which was sealed in the box), it took me through the Leopard setup like normal. Could it not have been wiped properly previously? -Safari crashes at least 3-4 times a day on random webpages. This never used to happen before -Applications keep asking for my keychain password to access it. I opened up keychain access and made sure it was unlocked. I also tried to delete and refresh the keychain but it doesn't seem to like that either. -I can hear my left side fan whooshing and blowing air even on idle at 2000rpm, the right side is completely quiet. When things ramp up to 6000rpm, the right side is audible, but the left one is humming/resonating. -I have the extremely annoying headphone hissing/beeping issue, and I know it can be fixed with high impedance headphones, but it should work out the box. Does anyone with a new MBP NOT have this issue? -Battery life is only about 3:00-3:15 on half brightness while surfing, chatting, and mail. It should be something closer to about 4hrs. Also, my max battery mAh is only 5450 instead of 5600. I have tried resetting the SMC and doing the full power cycle several times. My old macboook, I was able to keep it ABOVE the original capacity for over a year using the power cycling method. I contacted apple for a replacement but they said I have to go through the original point of purchase. What are my other options? I think I've received a lemon.
