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: 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: 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.
Problem: Playback of DVD is not smooth.
Solution: If you select the Maximum Battery mode for the Intel SpeedStep
™
technology, this problem may occur. This mode is designed to achieve
maximum battery life by switching the processor speed between the regular
low speed and half of that speed, depending on how much the processor is
used. If the use increases, Intel SpeedStep switches the processor speed to the
lower speed. Operation in this mode can severely degrade the performance of
the processor, and thus cause the playback of a DVD to be jerky.
To avoid or reduce this problem, you can choose any of three other modes of
operation, as follows:
v Maximum Performance: Keeps the processor speed high at all times.
