It appears that the RSS issue is happening to my MBP duo 2.2 lap top as well !!
My story is . . . when i unplug my AC my computer powers down within 3 seconds . . .
and with out AC power it will chime and immediately power off . . .FAK!
this machine works fine when plugged in . . .
so my problem could be defined as ” unplugged immediate shutdown syndrome”
i have tried a new battery fully charged and i have the same issue.
so if you where wondering ITS NOT THE BATTERY !!!!!!!
As this computer is only 14 months old i am some what perplexed on how to proceed? . .seeing as i dont have an apple care plan, An over sight i know .. BUT,
As far as i can tell from a large number of nightmare stories proved in great detail on this forum and many others it appears apple aint gonna do shit for me even if i had a care plan
so in short
what i can gather from the surfing around all after noon
it looks like these machines simply run to hot , over time they slowly cook them selves and create a number of short circuits are most often found around the heat sync
and power circuitry.
it dosnt take a physicist to work out what happens to complex circuitry that is exposed to sustained heat . . . .
the most likely the reason its “random” because it can effect any part of the complex circuitry in any number of ways.
based on my hypothesis this might explain why are a number of people who keep having issues long after batteries ,mother boards and heat sync are replaced,
So if there is any one keen on a class action suit or better known as a “civil case” in New Zealand and Australia im keen to throw mac book on the bonfire and start a Riot !!!
P.S a quick note to Apple
Back to the drawing Board!
and see you in court
good luck
