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 the BIOS Setup Utility, make sure that the device is included in the Boot priority orderlist. If it is included in the Excluded from boot orderlist, it is disabled. Select the entry for it in the list and press the x key. This moves the entry to the Boot priority orderlist.

If you are using the ThinkPad T41/T41p Series computer, in the startup menu in the BIOS Setup Utility, make sure that there is no exclamation point ! to the left of the hard disk drive or its child node. If there is such a mark, the hard disk drive is disabled. To enable the drive, press the Insert key and clear the mark.

Problem:
