Acer aspire 515 51 50y5 laptop
I have dual monitors and shut the laptop lid.
Intermittently, one or both monitors go to sleep. The laptop gives a USB unplugged alert. Wiggling mouse and/or keyboard presses wake it with USB connected alert sound but it takes seconds to redraw. This can happen several times in 5 minutes then not for hours.
I’ve switched power management to never sleep, disabled PC from putting usb devices to sleep in device manager, disabled selective usb suspend, disabled the monitors’ own sleep function.
Any suggestions to stop this happening?
