mac book shutting down unexpectedly

Question

mac book shutting down unexpectedly

Mac OS X

Version 10.6.8

Model Name: Mac Book

Model Identifier: MacBook 4, 1

Processor Name: Intel core 2 Duo

Processor Speed: 2.4 GHz

Having an issue with my mac book unexpectedly shutting down. I thought it was a battery issue, however just received and installed a new mac battery two days previously and the problem is still occurring. Sometimes it runs for 3 to 4 hours, at other times it shuts down before completing booting (will do so 2 or 3 times, then run for extended period of time). Any thoughts, suggestions would be appreciated.

Hi Kimberly...

Try Resetting the System Management Controller (SMC)

Try Troubleshooting the MagSafe adapter

Beyond that, if you are near an Apple store make an appointment at the Genius Bar or take your Mac to an Apple certified repair provider.

Resetting the SMC hasn't seemed to do the trick. I have, also, zapped the PRAM and run a repair disk permission (from disk utility - not from the original disk, however). Neither of those have solved the problem either. I was just sitting here uploading pics to Snapfish and it went black and turned off once again. Any other suggestions from anyone would be helpful. Thanks.
