    ok, so here's the thing.

    some days ago, the strangest thing happened. after i turn on the mbp, and safari i clicked the top sites button, and when the page displayed a message appears in all kind of language, saying that i have to turn off the computer by holding down the power button. 2 times that happened.

    Today another freaking thing happened, i was browsing multiple sites and had something else turn on, not very apps or nothing like that open at the same time, and the mbp just turned off, i guessed that was low batt, but the light in the button to open the lid wasn't blinking and i pressed the power button just to realize that it had simply turn off by itself and the battery life still had 80% and this happened also twice, today.

    Can somebody tell me, if this is some kind of "last breath" of the machine? lolol

    I must say that since december 2006 (when i recieved it) the usage was some how heavy, many many times turn on 24 hours straight or more, 5/6 hours non stop working having just about 4 hours rest and another amount of hours of working....oh yeah and the battery is almost dead.

    some help here?!

    PS: i know i got to have a desktop computer, working on it :eek:

    For this part, I'd make a guess that the battery indicator is no longer accurate. I've tried letting my old MBP (which is older than yours!) run itself down while on the battery and expected it to sleep or hibernate but it just completely loses power and shuts off - earlier than the battery indicator estimated. But I know my battery is defective and I'm not sure about yours.

    Perhaps perform an SMC reset?

    The first part is a kernel panic. This is usually a hardware problem.

    I bet your battery is done. How many cycles does it have?

    Health : 73% (i remember that was at 30 ish....)

    and it as 290 cycles.

    the battery at full charge can't stand up do about 30 min or so

    90% sure your battery is done for. The "sudden" power off (you lose all your work, etc...) is a symptom of a dying battery on pre-unibody MBPs... it sounds like it could be your case too. I believe apple rates them at 300 cycles or thereabouts... of course your mileage may vary.

    Good luck,

    i'm not surprised, i already knew that i've got to buy a new one...but i guess i would prefer to wait and buy a new imac, and then the new battery

    Kernel Panic and Dead Battery.

    That's a Kernel Panic. KP's are almost always hardware failures. First thing I would check is if you have bad RAM. You can run a mem check using Techtools Pro. If it's not bad ram, then it could be overheating or your Logic board is bad.

    Yep. Your battery is dead/dying. I have only 212 cycles, and it will tell me I have like 1.5 hrs left and the machine will simply turn off instead of going into sleep mode. The guy at Apple told me that the batteries are rated for 300 cycles, but has seen them go to 600.

    Apple is sending me a brand new battery for free. Good thing I have AppleCare.

    Does anyone knows what is the command line in the Terminal so i can see if the problem is hardware of software originated?

    Thanks
