Evening all,

My MacBook Pro has just turned extremely slow for no apparent reason, and the fan is really noisy.

I also cannot turn the machine off, every time I do it just restarts.

I'm running OS-X Lion 10.7.2.0.

After looking at various forums and posts and whatnot, I discovered this site:

Intel-based Macs: Resetting the System Management Controller (SMC)

Though this seemed to be the right way to go, so far nothing has been changed and I have tried a few times, and I suspect that this is because I have to hard shut down the computer because I cannot figure out how to shut it down using normal means.

Please help!

Thanks,
Kerrigor

Does it power off by pressing and holding the power button for 10 seconds? If so.. then yes, the SMC reset is the place to go... I'd ALSO reset the PRAM.

Please help!

Well, next up would be deleting preferences...

/Library/Preferences/SystemConfiguration

would be the location of the preference files in question, I believe. Personally, I'd just delete (or rename/move) the entire folder and reboot. It'll recreate the preferences on boot.. but you'll have to rejoin networks etc

Done that, then restarted and have also dled a fan speed manager and changed settings there.

My next step is to create a new user and see if its the same when logged in as them, as well as finding out if it's better in safe mode.

My problem is that the charger has now stopped working, it works intermittently and I really cannot figure out what is going on with it.

It can be connected but not charging, but it takes a while of wiggling it around for that, and then i try turning it off and on at the wall but it loses the connection. I am really not impressed with this Mac!

Any further ideas?

Thanks,
Kerrigor
