Attempted repair, failed: - Laptop has sleeping ability, but I can't find the setting for the kernel to make the computer suspend instead of shutting down. + Laptop has suspending ability, but I can't find the setting for the kernel to make the computer suspend instead of shutting down. Repair suggestions: 1. Persistence of session, so that everything would reappear after the restart. (this would also make updating less disruptive) 2.

Put the computer to sleep when it's too hot. + 3. Put the computer to suspend when it's too hot.
