Other problems

Problem: The computer locks or does not accept 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 turn off with the power switch.

Solution: If the standby indicator is on and you are working under battery

power, replace the battery with a fully charged one or change your power

source to ac power. If you still have a problem, press and hold the power

switch for 4 seconds or more; this forces the computer to turn off.

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

diskette drive.

Solution: Refer to the Startup menu of the IBM BIOS Setup Utility. Make sure

that the startup sequence in the IBM 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 by

checking that there is no ! mark preceding the device name.

Problem: Windows NT does not start; however, the message saying that

Windows NT is loading remains on the screen.

Solution: The USB setting might have been changed to Enabled. If so, it might

cause a conflict in allocating memory resources during startup. Disable the

setting, using the BIOS Setup Utility as follows:

1. Turn your computer off and then on again; then, while the message,

“Press F1 for IBM BIOS Setup Utility,” is displayed at the lower left of the

screen, press the F1 key to start the BIOS Setup Utility. The BIOS Setup

Utility menu appears.

2. With the cursor key, select Config; then press Enter.

3. Select USB by pressing Enter.

4. With the cursor key, select Disable; then press Enter.

5. Press F10 and Enter to save this setting and exit this utility.
