Solution
1.
Ensure that the computer air vents are not blocked and the
processor cooling fan is running.
2.
Open the access panel, press the power button, and see if
the processor fan spins. If the fan does not spin, make sure
the fan cable is plugged onto the system board header.
3.
If fan is plugged in and not spinning, replace it.
Solution
Shut down all open processor-intensive applications.
Solution
Double-click the Speaker icon on the taskbar, then make sure
that Mute is not selected and use the volume slider to adjust the
volume.
Enable the audio in Computer Setup: Advanced > Built-in Device
Options.
Turn on the external speakers.
Press the power button to resume from Sleep state.
CAUTION:
When attempting to resume from Sleep state, do not
hold down the power button for more than four seconds.
Otherwise, the computer will shut down and you will lose any
unsaved data.
Enable the internal speaker in Computer Setup. Select Advanced >
Built-in Device Options.
Some graphics cards support audio over the DisplayPort
connection (if applicable), so multiple audio devices may be listed
in Device Manager. Make sure the correct device is being used.
To access Device Manager in Windows 10, type device
manager in the taskbar search box, and then select Device
Manager from the list of applications.
