Yes I had a Surface Pro 3 with Linux on it and it still woke up in my bag sometimes. I'd take it out and it'd be running, boiling hot and battery almost depleted. I never figured out what caused it, maybe it was something in the firmware. Or something bumping the power button? However it was in a padded laptop compartment on its own.This was actually from full-off. Not even standby. What didn't help was that I used LUKS full disk encryption so it would be sitting there waiting for a password and there was no sleep timeout. In the end I found the SP3 was just not great for Linux, I had so many hardware issues. Sometimes I'd detach the keyboard and reattach, and it'd just not work. Or the pen would stop working or the rotation etc. Mind you this is around the time it came out. So a good while ago.
