An explanation for random MacBook shutdowns?

Just found this site after searching for problems with shutdown. Yikes can't believe so many problems!! I've just switched for the first time to macbook and I'm not so sure I made the right choice. My new macbook shutdown within the first hour of me using it and has done so several times since and I've only had it 2 days!!!

Are we sure that this RSS doesn't apply to the previous non-Intel model the PowerBook ?

(as I, along with my dealer & Authorized Appple Repair Center, have being going through an awful experience, changing mother boards, PS, memory, battery, HD, with a new Mac PB, recently bought in 1/2006 )

Regards

I've had my Macbook since May - actually ordered in May, but never received it until Mid-June :). That should have been my first sign of how slow things work. I've been on a waiting list for 2 weeks for the logic board to come in and be repaired. My store (authorized Mac repair shop) tells me to pay AppleCare (saying it's faster) AppleCare tells me to keep it local because no parts are available. Bottomline - I have a new MacBook that I can't even load my camera's photo's on without shutting down and no timeline on when it might be fixed.
I owned a Toshiba for 4 years before this without a problem and was curious to try the MacBook and Bootcamp - (oddly, bootcamp has yet to shut down since I've started having the Mac side shut down.) I'm very dissappointed with my Mac experience and hope they truly do something to make it right quickly.

My company just purchased me a macbook and it just started happening about 2 days ago, I have had the unit for about 3-4 months. I thought it was something that would go away (possible bug) but, know when ever I get to work it will do it in the morning then run ok the rest of the day. Personally I think austin above works for apple and is probably trying to down grade the issue. Good luck Austin but, you cannot hide truth.....

After being a happy MacBook owner for about 3 months, my MacBook started to have this random shutdown syndrome. I use White MacBook, 2GHz, 2GB RAM. I always watch my CPU temp by 'CoreDuoTemp' software. Most of the time, it happens almost immediately after being waken up from the sleep state. Temp is always around 35-45 degree when it happens. Sometime I have to restart for several times for my MacBook to work normally. I'm sure that it's not heat-related and I'm sure it's a hardware problem, because sometimes it happens just before loading any O.S. components. I used to be a pround Mac owner and showed my Mac to Windows users that my Mac never required a reboot and never had unexpected crash. Now I can't say that again. I don't really want to bring my MacBook to service right now because I think Apple itself can't reliably identify the origin of the problem.

P.S. My serial no. is 4H62205AU9C.

Have had my MacBook for about 4 months now, and today had my first shutdown problem. My scenerio was this:

1. Plugged in and turned on my MacBook. Work on it for about 30 minutes then left for my meeting. I left my MacBook ON and it was recharging.
2. Returned about an hour later and found my MacBook OFF, not asleep. The MacBook power indicator now showed the MacBook fully charged.
3. Turned MacBook on and started working for a few minutes, then it went off.
4. Turned MacBook on again, and again it turned off just after a few minutes.
5. I unplugged the powercord and ran my MacBook in battery mode. No problem while I was in battery mode.
6. Plugged the powercord back into the MacBook and it ran for the rest of the day in recharging mode. I turned it off before it got fully charged.

I would have to say that if it were a heat issue, I would expect it to turn off while I was using it later in the day, not while I was away from it. I also found it interesting that it shut down at least two times (possibly three) while the power indicator was green, and I did not have any problems in battery mode or charging mode. Can anyone verify if they ever had the shutdowns in battery or charging mode?

I'm rapidly losing my patience with my MacBook. After two months of trouble-free usage, I now suffer shutdowns 4-5 times each day, which is incredibly disruptive.

Apple, please pulll your finger out and get this sorted!

Had the same problems. Went to Apple for fixing the problem. Had my computer back after 4 weeks ! Hard drive and logic board replaced.
The computer STILL shutdown randomly.
Pathetic and sad.

I'm into my third week with my black macbook. Tonight it seemed to be troubled after leaving it running for a few hours alone. The shift key was lit with it's green light but don't remember shifting it or seeing the green light glowing before I left it alone earlier today. Anyway, even though I pushed the shift key again, the light continued glowing and the mouse was moving unusually slow. After shut down, it would not restart.

Ive tried removing power cord, battery, holding power button down for over five seconds .. more like 30 seconds. Nothing. Reattaching battery and cord pushing power and or holding power ... nothing.

I've tried command option p and r keys, after pushing the power button just once .. nothing. In the next go around, held it down with the command option p and r keys during restart ... nothing. Seems pretty dead alright.
