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

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

Configuration Program.
