Power management causing system sleep

4.5

The computer enters sleep mode unexpectedly, even while you are using it or a task is running.

Symptoms
  • Sudden black screen
  • Downloads interrupted
  • Session locks randomly
Possible Causes
  • Aggressive power saving
  • Faulty lid sensor
  • Overheating

Step-by-Step Fix

1

Increase Sleep Timeout

Set "Sleep after" to a longer duration in Power & Sleep settings.

2

Check Lid Settings

Ensure "When I close the lid" is set correctly and the sensor isn't being tripped by magnets.

3

Monitor CPU Temp

Some systems force sleep if the processor hits a critical temperature.

When to See a Technician

A "Sleep" event in the System Log can tell you exactly what triggered the transition.
