ASUS Certified System Troubleshooting 3

Question 1

An ASUS laptop's touchpad stops responding after a Windows update. What is the FIRST troubleshooting step?

Accepted Answer

Roll back or reinstall the touchpad driver from ASUS support

Answer

Windows updates can overwrite OEM touchpad drivers with generic ones; reinstalling the ASUS-specific driver typically resolves the issue.

Question 2

A user's ASUS NUC shows 'CMOS Checksum Error' at every boot. What is the MOST probable cause?

Accepted Answer

Dead or weak CMOS battery

Answer

A dead CMOS battery causes the system to lose BIOS settings and generate a checksum error at every power cycle.

Question 3

During POST, an ASUS motherboard displays 'CPU Fan Error.' The CPU cooler is spinning. What is the MOST likely cause?

Accepted Answer

The fan is connected to the wrong header or the RPM is below the BIOS threshold

Answer

ASUS BIOS monitors specific fan headers and will trigger an error if RPM falls below the configured minimum or the fan is on an unmonitored header.

Question 4

An ASUS desktop's USB ports on the rear I/O work, but front panel USB ports do not. What is the MOST likely cause?

Accepted Answer

The front panel USB header cable is disconnected from the motherboard

Answer

Front panel USB connectors are routed through a header cable to the motherboard; if unplugged or loose, those ports will not function.

Question 5

A technician is troubleshooting an ASUS system where dual-channel RAM is not being recognized. The sticks are installed in slots A1 and A2. What should be done?

Accepted Answer

Move the sticks to the recommended dual-channel slots (typically A2 and B2)

Answer

ASUS motherboards require RAM to be installed in specific paired slots (usually A2/B2) to enable dual-channel mode.
