Source device issue
A beeping sound is heard when my PC is booting.
If a beeping sound is heard when your PC is booting, have your PC serviced.
While in power saving mode, the computer or monitor screen turns on although there is no keyboard
or mouse input.
This issue occurs when the Wake On Lan (WOL) feature on your computer is turned on and does not
mean a problem with the product.
If your computer uses Windows (e.g., Windows 7, Windows 8, Windows 8.1 or Windows 10), navigate to
Control Panel → Network and Internet → Network Properties (Configuration), and set the Wake On
Lan (WOL)-related option to "Do not use."
