Chapter 4. Troubleshooting

This chapter provides information about what to do if you experience problems with the mouse.
Problem: The mouse cannot wake up the computer from sleep mode when you connect the mouse to the
Always On USB connector on the computer.
Solution: Connect the mouse to another USB connector on the computer instead of the Always On USB
connector.
Problem: I cannot install an earlier version of the device driver if a later version of the device driver is installed
on my computer.
Solution: To install an earlier version of the device driver, uninstall the later version of the device driver from
your computer first. For more information, see "Uninstalling the device driver" on page 3.
Problem: The computer cannot detect the mouse if I have ejected the mouse as an external device from the
Windows notification area of my computer.
Solution: Disconnect the mouse cable and then reconnect it to the computer. The computer will detect the
mouse again.
Problem: I have associated my fingerprints with the Windows password through the fingerprint reader of the
computer only. I cannot log in to the Windows operating system through the fingerprint reader of the mouse.
Solution: The fingerprint reader of the mouse works independently from that of the computer. To solve the
problem, associate your fingerprints with the Windows password through the fingerprint reader of the mouse
first. Then, scan the enrolled fingerprint with the fingerprint reader on the mouse to log in to the Windows
operating system. For more information, see "Enrolling your fingerprints" on page 5.
Problem: I have associated my fingerprints with the power-on password, hard disk password, and Windows
password through the fingerprint reader of the computer. After associating my fingerprints with the Windows
password through the fingerprint reader of the mouse, I cannot log in to the computer through the fingerprint
reader of the mouse.
Solution: The fingerprint reader of the mouse can replace the Windows password only. To log in to the
computer, do one of the following:
• Use the fingerprint reader of the computer.
• Enter the power-on password and hard disk password. Then use the fingerprint reader of the mouse.
