My battery will only go to 83% and it dies after 5 mins if i dont have the power cord plugged in the computer. Can anybody tell whats wrong with my computer or if anybody has had this problem, Thanks

How old is the battery? Most batteries lose there ability to hold charge after a certain period of time. While 5 minutes is rather extreme, it does happen. CoconutBattery provides some useful stats. about battery usage, to help gauge.

i have exactly the same problem only i don't even get 5 mins from my battery, even though when I take it out the LEDs read that it has maximum charge.
i've scrupulously followed the instructions to reset the PMU... doesn't work
(i've got 1.67 ghz 15in model).
where next? a new battery costs a lot in the UK - about $175 - so keen to avoid buying new one...
