Disable sleep mode

This means that the sensor of the lid is probably damaged or detecting a magnetic field somewhere.

Somewhere on the left edge, if you hold a magnet, you will see the laptop go to sleep. Make sure there is no magnet close there.

You can disable the laptop from going to sleep if it "sees" the lid closing. Make then only sure that you need to let the laptop sleep by yourself.

Sleep mode pauses and suspends your computer until you are ready to continue. In some cases, sleep mode interferes with scheduled tasks or operations such as remote desktop connections. Microsoft allows sleep mode to be turned off and disabled for users that have no need for the function or find that the feature is interfering with their normal computing activities.

It is likely going into a sleep mode.

You can try updating your BIOS to see if this resolves the problem, otherwise you can disable sleep mode from occuring.

I am going to assume you have Windows OS.

- BIOS drivers will be available from the Asus website.
