So i have the mid 2007 (i think) non unibody white macbook. Yesterday after some normal usage i noticed the battery had only 30 minutes left even though it had 94% left, also the Service battery Now message had appeared This was odd cause even though my mac is quite old a few days before the battery was lasting a normal 4-5 hour charge. after leaving it charging over night after trying to recalibrate the battery(i dont think it actually ran all the way down as it lasted minutes while not on battery power even though it was 99%), resetting the pram, nvram and SMC, the battery now reports 20 hours of life left, but the "Replace now" message came on. now obviously i would be ok with 20 hours of life left, but its had 20 hours left for 30 minutes an hasnt decreased Ive googled and searched the forums but couldnt find an answer ... coconut battery reports current charge - 65336 mah max charge - 65336 mah current capacity - 65336 mah max capacity - 5020 mah 1301% model - macbook5, 2 age - 18 months loadcycles - 273 temp 30.6 degrees C power usage - 11.0 watt more specs OSX version 10.6.3 2ghz intel core2 duo 2gb 667 MHz DDR2 SDRAM possible problems? my install of snow leopard is fairly recent and ive seen accounts of stuff like this happening (i googled a lot after getting this problem) a piece of my L bracket broke off after the same time the problems started to happen(yesterday), it was the little metal "nub" that pushed the spring dealio on this side of the battery up i replaced the HDD with a larger/faster one and it has been in for a while (the battery took a little hit when it was first installed but otherwise it was fine) so im stuck, do i need to go to the nearest apple store (far away) to have it checked out or is it another issue?
