To determine if the computer’s external USB devices are functioning properly, perform the
following procedures. Figure 2-6 outlines the process. Start with Procedure 1 and continue as
instructed.
Procedure 1: External device and connection check
Procedure 2: Replace system board
Procedure 1
External device and connection check
The USB device may be damaged or the connection may be faulty. Perform Check 1.
Check 1
Make sure USB device cable is firmly plugged into one of the USB sockets. If the
cable is connected correctly, go to Check 2.
Check 2
Plug the USB device into another USB socket (there are three in all). If the USB
device still does not work, go to Check 4.
If the device functions correctly when connected to another USB port, go to
Check 3.
Check 3
Make sure that the USB socket is firmly secured to the system board of the
computer. If the malfunction remains, the system board or USB small board may
be damaged. Go to Procedure 2.
Check 4
Connect an alternative USB device to one of the computer’s USB ports, and then
boot the computer. The computer automatically detects the external device.
If the alternative USB device works correctly, the original device may be
damaged and should be replaced.
If the alternative USB device appears to have the same problem as the original
device, the system board or USB small board may be damaged. Go to Procedure
2.
Procedure 2
Replace system board
If the error persists, the system board or USB small board may be damaged. Replace it with a
new one following the instructions in Chapter 4.
