7. Keep your computer away from strong magnetic devices

The issue of Windows randomly sleeping is common on laptops. This happens when a laptop’s sleep mode is triggered by a magnet from a nearby device such as a smartwatch or smartphone. It may sound strange, but one user realized the same thing and posted it on the Microsoft Community forums. It turns out that the laptop screen and keyboard have magnets. When you close the lid, the laptop’s magnetic sensor detects the interaction between these magnets and puts the laptop to sleep.

Now, when we bring the magnetic device close to the appropriate place on the laptop, the interaction between the two magnets causes the operating system to think the laptop is closed. As a result, the OS puts the laptop into sleep mode. The best thing you can do to handle this situation is to remove all electronic devices, including magnets, from your laptop.
