MBA runs hot in bag

Last Friday I had some scary experience with my MBA. I sit down in a bus going home and want to work a bit on the MBA. The screen didn't turned on and remained black. There was no life sign of MBA and I though: ok, the battery will be down; lets wait for home and enjoy some music.
40 min later I'm home and unpack my MBA from its bag and it hot like nothing I ever had before plus the fan where running like to cool down hell.

Something was starting the MBA while being in the bag; but I have no idea what that could have been. The MBA is while in the bag overed by some thicker cloth; so I assume that an unintended open of the lid is not the reason which could lead into a wakeup.

These kind of hot apples I don't really like.

Any idea ?

Thanks; that was a good hint. Bluetooth could be one of the reason as my headset connected to iPhone is also BT; another possible reason would be the shared connection I might kept running.

To make sure I might make a shutdown; the little beast is fast enough.
Anyway: a helpful link.

Punched on my iPhone; that's why spelling might be wrong.

I had the same problem with sleep because of a BT Logitech mouse.

I unchecked the ”Allow Bluetooth devices to wake this computer” from BT Preferences/Advanced and it works great now.

Actually BT is off on the MBA; plus the settings you mentioned are also inactive.


I guess I will watch the next days my user behavior and check more often if the little on get fever again. Might be really "user error".
