Do not leave XPS laptop in any sleep/hibernate/standby mode when placed in a bag
I stopped using my Microsoft Surface Pro because it had the same issues. It's a clusterfuck of bad design decisions at Microsoft, the most offensive one being that they prioritize the execution of their scheduled spyware upload (telemetry) over honoring the agreement with the user that a sleeping PC will remain asleep unless the user takes action. It'll even install updates at night and then make reboot sounds to wake you up. And the next day, your unsaved open documents are all gone. Plus as described here, many Windows 10 laptops will either burn themselves, or the battery will be empty whenever you need em.
