Ask HN: How to prevent “boil in bag”-laptop

So, basically, you want the laptop to turn off and stay off, by just closing the lid.

The reason this doesn't always happen, might be down to Windows Update I presume (or some other application preventing shut-down). Maybe, you can look into changing the configuration/behavior of Windows Update. If it's a "Home" edition, you might not be allowed to turn off automatic updates though...

See if you can switch the sleep mode in the BIOS to S3 or a Linux mode if it exists. Modern Standby seems to be the culprit for the boil-in-bag phenomenon.

Push the on/off button and check that the disk activity light is off.

Just hibernate the laptop and then remove the battery.
