[M.A.S.]

I have a rev A 17" PB and here's what's happening,

Wakes from sleep, but sometimes trackpad and keyboard don't work, restart needed.

when on battery power it goes from 30 min - 0 instantly.

shuts-down without warning, there is no "reserve battery power" warning.

I've done a clean install (thought this would cure all ills)

reset PMU and zapped the PRAM.

I'm outta ideas. Because i got it from John Lewis (department store in the UK) i got a 2 year warranty so it's still covered.

Any help appreciated!

maybe the backup battery on the motherboard is dead.

def take it in asap.
