Hey, everyone, I've had a 2.66 GHZ 13" MBP Mid 2010 model for 1 year 9 months and suddenly yesterday when I unplugged the computer (after it having been plugged in all night), it just turned off. I couldn't turn it back on without it being plugged in. Basically, the battery is dead. The battery status is not charging and Replace Now. I have had battery problems with this machine from the beginning where it would turn off at 0% battery rather than going into Safe Sleep mode. I had noticed over time the battery health had gotten down to 80%, which seemed somewhat normal to me given that I use it every day for business. But just last week it was still able to run for hours at a time off of AC power. iStat now reports 0% health. I called Apple, since I have AppleCare, and they asked me the cycle count, which is high at 1,396. I get that that is high. And I do use the computer a lot. But I don't even think it's really technically possible for the count to be that high given that I used the computer plugged in most of the time. Anyhow, even if the count were that high, Apple's web-site says that after 1,000 cycles the battery will still retain 80% of its original charge. The tier 2 specialist I spoke to said that the battery is not covered after 1,000 cycles. I can understand the capacity of the battery slowly going down over time, but does anyone have any experience to speak to this to say whether it's normal to go from working off battery for hours at a time at 80% health to not working at all and 0% health overnight? This computer also runs very hot--usually around 200 F--and the fans are always at 6200 RPM, so I also wonder whether the heat hurt the battery. In fact, this computer has a lot of problems, but since I use it for work every day, I have never sent it in to be replaced. I've replaced the hard drive and memory myself when they failed because I preferred paying out of pocket to being without it for up to a week. Plus the DVD drive has a disc in that won't come out--the only disc I ever put in it, actually. But I've just put up with those because it's easier than trying to find a loaner computer, which Apple doesn't even offer for a fee. I took it to an Apple authorized service provider today (my closest Apple Store is far away), and the place was a bit sketchy. They're charging me $174 for a new battery even though it's $129 through Apple. They didn't even know that they would have to install it for it not to void the warranty (which is the real problem with all thisI don't care if the battery is internal or not, but I wish they would sell it off the shelf so I could install it myself). So I am going to have to pay them to install something I don't even think they know how to do because that somehow doesn't void the warranty, whereas me following an iFixit guide would. Sorry to rantit's been frustrating. But if anyone has heard anything about heat causing this or if anyone knows if this is a normal progression for a "consumed" battery that would be helpful when I deal with Apple later on.
