Laptop draining battery by trying to cool itself while in bag.

[Florianc]

Sometimes - without a clear reason - my laptop decides to go out of sleep mode while in my bag.
When it does this the fan turns on, but as there is no actual air flow all this does is heat up the laptop and drain the entire battery.
I think a possible solution might be to ensure the laptop can't get out of sleep mode while the screen is down. Is it possible to somehow do this?
Any alternative suggestions of course are also welcome!

The problem with any new laptop is Win10 -- as MS decided to implement a new hibernation scheme BY DEFAULT.

While the good news is that this is supposed to dramatically shorten the re-boot time, the bad news is that something as simple as pressure on the touchpad can awaken the laptop.  My guess is that this is what is happening to yours (presuming it has a touchpad).

I have a similar problem with my HP laptop, so I changed the power plan to (1) disable Fast Startup (the new hibernation scheme), and (2) shut down the laptop completely.  While this does take longer to restart the laptop, since I have an SSD, that only takes a few seconds, and the big PLUS is that it does not restart on its own when in the bag.

Your PC -- your choice.
