Macbook Shutdown Problems

[bandito22]

Hi,

I am new to Mac's and have a macbook 13" which was ex-display and had a couple of issues.

It had a dodgy battery, which has been replaced and that sorted some of my problems.

However, I still have an issue with the macbook shutting down on boot-up.
It generally will run ok for a while, then at no particular time and for no particular reson, it switches itself off again.

I have read something about the SMC flashing. My version is 1.4f8.

I am beginning to think it is more like a hardware problem. The unit is out of warranty but Apple replaced the battery for free, should they be obliged to replace the other parts too if it hardware related?

Thanks in advance.

There was a a random shutdown problem with MacBook's last year that was found to be a hardware issue. I'm not sure how old yours is but if you google macbook random shutdown you'll find the issue.

If I remember rightly there was a problem with a cable that ran close to the heat sync and when the machine hot hot and the heat sync expanded, it caused a short. Again, if I remember correctly Apple fixed the problem but you could fix it yourself without too much difficulty if the machine is out of warranty.

Good luck and remember, in this case, Google is your friend.

Cheers.
