Why is this happening? When my PC is in stand-by mode, I used to be able to tap my mouse a bit

Question

When my PC is in stand-by mode, I used to be able to tap my mouse a bit and my PC would come back on, now I literally have to press the power button for it to turn back on. Can someone help me please?

Answer 1

Go to Control Panel and check your Power Options

Answer 2

It's your power settings, as the other user said. If it sits too long it's powering down further and further until it hibernates.

Or it may still be in a deeper standby mode, but your USB mouse is not receiving any power and therefore can not wake the computer up.
