Intel Mac :: Why Does It Often Freeze After Turning On From Sleep Mode
Apr 28, 2012I've been using Pc's for the past 30 odd years so am totally new to Mac. I'm doing my best to adapt to this new different OS and so far have found some things more user friendly but others ? I've more or less given up on those as Mac doesn't seem to do those things. These are probably Windows based and I'm assuming Mac has its own alternatives that I haven't discovered yet. Anyway, my immediate problem is this goddamned frustrating situation when I try to re-activate the comp' after waking it from 'sleep'. Sometimes its fine but others, it comes back on but freezes and the only option I have is to turn it off at the switch and do a re-boot!

MacBook Pro :: Fan Turning On And Off?
Sep 10, 2010I have an i7 MBP and this morning I discovered that its fan is turning on and off at about 2 second intervals. It only occurs when the lid is closed and (seemingly) when the battery is at full charge (i.e., the mag safe is green). As soon as I open the lid the fan comes on and stays on for 30 seconds or so then shuts off as if the system has cooled. Any ideas what this is about?

May 19, 2008I have an old powermac G4 dual 1.42 the other day I decided to power it up to update it and it would not turn on. I push the power button it lights briefly and goes out. The light stays on if I hold the button down. The fan does not come on nor any noise from inside the case, etc. I have reset the pram, that little button, and I have replaced the battery, I have searched for the problem but nothing seems to fit my exact case. It's not my main computer and I am no where near an apple store and I'd rather fix the problem myself instead of paying an arm and leg for apple to repair it.

Jan 31, 2010i'm having a small issue with my computer... Its not turning on
1) If i just press on the power button i just hear the optical drive shifting and then nothing.
2) If i hold down on the power button, the optical drive starts up, the hard drive starts up, the sleep light turns on.. glows a little then faints and nothing.
The screen never turns on in either case and i never hear the start up sound.I had this problem twice already and solved it by reseting the Pram and by trying to turn it on and off a few times ( eventually it just turned on.. ) . But this time i guess that just won't do.
