Solving computer problems

vRestart closes the Rescue and Recovery workspace and resumes the startup sequence that was interrupted.

Other problems

Problem: The computer locks or does not accept any input.

Solution: Your computer might lock when it enters standby mode during a communication operation. Disable the standby timer when you are working on the network.

To turn off the computer, press and hold the power switch for 4 seconds or more.

Problem: The computer does not start from a device you want, such as a diskette drive.

Solution: Refer to the Startup menu of the BIOS Setup Utility. Make sure that the startup sequence in the BIOS Setup Utility is set so that the computer starts from the device you want.

Also make sure that the device from which the computer starts is enabled. In the startup menu in BIOS Setup Utility, make sure that the device is included in the “Boot priority order” list. If it is included in the “Excluded from boot order” list, it is disabled. Select the entry for it in the list and press the x key. This moves the entry to the “Boot priority order” list.

Problem: The computer does not respond.

Solution: IRQs for the PCI are all set as 11. The computer does not respond because it cannot share the IRQ with other devices. Refer to the ThinkPad Configuration Program.

Problem: You may receive an “Unsafe Removal of Device” message that mentions the USB 1.x device when you resume from suspend or hibernation in Windows 2000.

Solution: You can safely close this message window. It is displayed because of a USB 2.0 driver problem in Windows 2000. You can get detailed information in the More Information section of the Microsoft Knowledge Base 328580 and 323754. Visit the Microsoft Knowledge Base homepage at http://support.microsoft.com/, type the number of the knowledge base article you need in the search field, and click the Search button.

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