Hi, I love my rMacBook Pro 15" had it a couple of weeks. Open box at Best Buy. Great deal. One cycle on the battery and had a Samsung display. It is a great machine! So now to my question. I usually just close my lid a few minutes before I leave the office. Put the machine in my bag until I get home. I have turn off the option of wake while sleeping on Battery in power management. I took out my machine place it on the desk plugged it in to charge and forgot about it. Came up just a minute ago and found it warm. Open it up look at iStat and found the CPU temp 153 degrees F. I think that's strange, but then remember I did not disable the Power Nap option while on charge. No big deal now because my Mac was open on my desk. I remember though earlier this week, didn't take it out of my bag I just unzipped it and plugged in a charger. Look at iStat and my CPU die temp was over 180!! Ok so I have now disabled Power Nap while on charger. I will now take my machine out of bag all the time. My question are there any things I should worry about? Any thing I should check. She seems to be working fine now. Thanks for any help. Maybe this will help someone else too!!
