Solution: On the Boot menu of ThinkPad Setup, make sure that the hard disk drive is on the Boot priority order list. If it is on the Excluded from boot order list, it is disabled. Select the entry for it on the list and press Shift+1 to move it back to the Boot priority order list.

Problem: After setting a hard disk password on the hard disk drive of the computer, you moved the drive to another computer. Now you cannot unlock the hard disk password.

Solution: Your computer supports an enhanced password algorithm. Computers older than yours might not support such a security function.

Solid state drive problems

Problem: When you compress files or folders by use of the data compression function in Windows, and then decompress them, the process of writing to or reading from the files or folders is slow.

Solution: Apply the disk defragmentation tool in Windows for faster access to the data.

Optical drive problems

Problem: The optical drive, such as a CD, DVD, or CD-RW drive, does not work.

Solution: Make sure that the computer is turned on and a CD, DVD, or CD-RW is properly loaded on the center pivot of the drive. (You should hear a click.)

Make sure that the drive connector is firmly connected to the computer. If you use an option that has a bay for installing the drive, make sure that the option is firmly connected to the computer and works properly.

Make sure that the drive tray is firmly closed.

Make sure that the device drivers are correctly installed.

Problem: You hear a noise from the drive when the CD, DVD, or CD-RW disc is spinning.

Solution: If the disc is not correctly loaded on the center pivot of the drive, it might rub against the drive cover and make a noise. Make sure that the disc is loaded correctly in the drive.

Problem: The tray does not open even if you press the eject button.

Solution: When your computer is not turned on, pressing the eject button does not cause the drive tray to open. Make sure that the computer is turned on and that the drive connector is firmly connected to the computer.

If the tray still does not open, make sure that the computer is running, and insert the end of a straightened paper clip into the emergency eject hole. The tray will open.

Problem: An optical medium, such as a CD, DVD, or CD-RW disc cannot be read.

Solution: Make sure that the CD, DVD, or CD-RW disc is not dirty. If it is, clean it with a cleaner kit.

Test another CD, DVD, or CD-RW disc. If the computer can read the other disc, the first disc might be defective.

Make sure that the disc is loaded on the center pivot of the drive with the label side up. (You should hear a click.)

Make sure that the disc is in one of the following formats:

Music CD

CD-ROM or CD-ROM XA

Multisession photo CD

Video CD

DVD-ROM (DVD-video)

Problem: The computer cannot play a CD, or the sound quality is not good.
