my macbook pro suddenly shuts down

Hello everyone,

I am having problems with my MacBook Pro.

It suddenly shuts down without any warning. I tried turning it on, a few seconds after the sound, it would shut down.

I read the User Manual and tried a command "press Power Button, and immediately hold down Command Option, P and R Keys simultaneously" and my laptop turns on. Sometimes it would still suddenly shuts down.

I also noticed that the mouse sometimes isn't as responsive as it used to, very slow.

I also downloaded iBoost to see if it helps.

Hope to hear from you.

Thanks.

MacBook Pro, Mac OS X (10.6.8)

Thanks Dominic23 for your reply.

What I noticed from the link you sent is:

Portable computers that have a battery you should not remove on your own include MacBook Pro (Early 2009) and later, all models of MacBook Air, and MacBook (Late 2009).

Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

I bought my MacBook Pro last December 2010...will this be OK if I follow the steps? Even it was mentoned for models early 2009?

Thanks and best regards.

Yes. It is OK.

If SMC reset does not help, please contact Apple as soon as possible.

I had this problem too and took it to 2 'certified' mac repairers that charged $70/hr and ended up not fixing the issue. We then just went to the Mac store, where they said it needed a "tune up" and charged us $40. They ran diagnostics and said spotlight wasn't working, the hard disk needed repair, and that it's a software issue not a hardware issue. It's fixed, and I've had no more random shut downs.
