Is anything displayed on the monitor?
There is a problem with the system unit if:
Yes
•
A three or four digit error code appears. Find the code in "Error codes, descriptions, and corrective actions" on
page 57, and take the action listed.
•
A box containing an error code and message appears. Follow the instructions in the message. For instructions on
using the Configuration/Setup Utility, see page 63.

a. If you are working in Microsoft Windows:
Complete these steps to reset your computer, and then follow the steps under "Monitor Horizontal
Frequency" on page 11 to select another setting.
1. Disable the Power-on Password option in the Security feature of the Configuration/Setup Utility.
2. Record any Configuration settings that you have changed (customized) from the default settings (for
example, Monitor Horizontal Frequency). You will have to re-enter these later. For instructions on using the
Configuration/Setup Utility, see page 63.
3. Turn off the system unit. Reset your computer by holding down both mouse buttons while you turn on the
system unit. Release the mouse buttons when something appears on your screen.
Note: Resetting your computer changes all of the settings in the Configuration/Setup Utility to the factory
defaults. After resetting your computer, re-enter any customized settings in the Configuration/Setup
Utility.

1. Turn the computer on. If the computer is already on, press the Ctrl, Alt, and Delete keys at the same time to
restart it.
2. When a small white box appears in the upper left corner of your screen, press the Alt and F1 keys at the
same time.
3. When the "Recovery Choices" screen appears, press V.
4. See "Setting up your monitor in OS/2 Warp" on page 9 to choose the correct settings for your monitor.
