[gambiting]

>>Then Microsoft had the episode where some of their Surface hardware would not reliably stay in sleep mode and cooked itself while being transported in a bag

To be fair, I've had exactly this with a Dell, MSI and a Razer laptop in the last few years. The only way I can reliably get it to stop waking up while asleep(and never going back to sleep) is disable sleep entirely and use hibernation instead. It's insane that such a basic functionality seems to be broken across a whole range of hardware.
