Lenovo ThinkPad T61 User Manual

Problem: I cannot hot-swap the hard disk drive in the Ultrabay.
Solution: You can hot-swap a hard disk drive in the Ultrabay only if no hard
disk password has been set. Make sure that the password for the
hard disk drive in the Ultrabay is disabled.
Problem: I cannot change or remove a hard disk password in the BIOS Setup
Utility.
Solution: The setting of Using Passphrase in the BIOS Setup Utility must be
consistent between setting a hard disk password and changing or
removing it. If the Hard Disk x Password menu in the BIOS Setup
Utility is grayed out and unavailable, remove all other passwords.
Then turn off your computer and uninstall the hard disk drive. Turn
on the computer with the hard disk drive uninstalled, enter the
BIOS Setup Utility, and set Using Passphrase as enabled or
disabled, whichever was its setting when you set the password. Exit
the BIOS Setup Utility, and turn off the computer. Replace the hard
disk drive. Turn on the computer and enter the BIOS Setup Utility
to change or remove the hard disk password.
Fingerprint authentication problems
Problem: You cannot register or authenticate your finger because it is
wrinkled, rough, dry, injured, stained, oily, wet, or different one
from what you have registered.
Solution: To improve the situation, try the following:
v Clean or wipe your hands to remove any excess dirt or moisture
from the fingers.
v Enroll and use a different finger for authentication.
v If your hands are too dry, apply lotion to them.
Startup problems
Problem: The Microsoft
®
Windows operating system will not start.
Solution: Use the Rescue and Recovery workspace to help solve or identify
your problem. For details about Rescue and Recovery, see
