RE: XPS 15 Shutting down instead of sleeping on battery

- Try reflashing BIOS as suggested above - this seems to reset certain weird states sometimes

- In the Advanced Power Options (in power profile settings), set Sleep / Hibernate After to Never (0) - this is intended to prevent losing your work due to battery drainage after prolonged sleep, but the switchover seems to fail sometimes.
