Hi everybody!
A while ago, I was given a lot of useful information that lead me to buying a MacBook Pro (15'', 2011, Lion) on this forum. Thanks again for that!
Now, just a bit under 2 months after buying it, it's starting to behave in a weird way.
Everything seems to be very slow lately (it needs about 2-3 seconds to display a small jpg image in the preview, for example). Other programs are starting quite slowly, too. Once a program has started/is running, everything seems to be fine (or at least I never noticed any slow moments).
This behavior makes me think that my MBP might have a problem with the HDD (500 GB, 7200 rpm). Unfortunately, I am not able to run Apple Hardware Test. I tried holding down the D and the C key on booting (not at the same time, of course), but that did not do the trick. I even started from the recovery partition, but could not find it on there, either.
So here's question number one: how do I check my harddisk for errors? Any hints on how to run AHT on Lion?
I am not sure about this one, but atMonitor tells me that my CPU is running at ~52° (Celsius, approx. 126° Fahrenheit) - is that normal? The GPU runs at ~56° Celsius (uptime slightly under 2 hours).
Alright, on to question number two: lately, I sometimes get an error when I shut my system down. It then tells me that I have to hold down the power button until it switches off and then restart it. This did not happen before, I think it started about 10 or 14 days ago. What is that? Any ideas how to fix it?
I am willing to reset the machine to factory defaults (although I'm quite worried about my bootcamp partition - how hard is it to bring everything back to a working state?) if I have to - but if I can somehow fix it without resetting it, I'd be glad.
Any help is appreciated
Greets and thank you in advance - steps
