Or in the office, the hardware-software relations between the laptop and Windows and in some parts Linux are strained at best, where drivers, power management, and so on get crappy. E.g. after a year or two of updates, it gets out of control and nice things like hibernations don’t work. It’s usually a driver for some small thing you don’t care about that forgot to read the Windows specification change and now it can’t do that power handling in a good way. Oops the computer refuses to sleep and your bag is burning, your battery is 1% when picking the computer up again.
