Solving computer problems
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 turn off with the power switch.
Solution: If the standby indicator is on and you are working under battery
power, change your power source to ac power and push Fn key to resume
normal operation, then shut down the computer.
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. If there is such a
mark, clear the mark to enable the device by pressing the Insert key.
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 IBM BIOS
Setup Utility.
Problem: Playback of DVD is not smooth in Windows
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.
