Configuration Problems - HP Tc2120 - Server - 256 MB RAM Maintenance Manual

Chapter 6
If you should find bent pins, slowly but carefully straighten each pin. If necessary, replace the cable.
6. Turn on the server and wait a full 2 minutes.
7. Verify the monitor starts displaying normally.
8. If the problem persists, check if the monitor is functioning:
a. Turn off the monitor and the server.
b. Disconnect the video cable from the video connector.
c. Turn on the monitor.
Monitor Notes:
When most VGA monitors are disconnected from the video connector, if the monitor is working, the
screen is white.
When some monitors (such as HP high-resolution monitors) are disconnected from the video con-
nector, the monitor may be working, although the screen is black.
d. If a monitor tester is available, use it to check the display.
e. If you suspect the monitor is faulty, replace it with a known good monitor.
f. Verify the new monitor is operating properly and then reinstall the original monitor and duplicate the
error.
9. Verify the monitor is working by plugging it into a known-good server or computer.
10. If you are using a video screen saver utility and the screen goes blank while using the keyboard, you may
be using an application that turns off the screen even when you are using the keyboard.
Refer to the manual provided with the screen saver utility.
11. If the monitor displays a badly scrambled image that looks to be the current screen image, then the monitor
is not synchronizing correctly. Call your HP Customer Support provider.
12. If a message appears such as "INVALID CONFIGURATION," press F10 during the boot process and run
the Setup Utility to confirm the server video configuration.
Verify the other accessory boards do not use the same memory addresses as the embedded video connector.
If the problem persists, call your HP Customer Support provider.

Configuration Problems

Symptom:
•
An installed driver cannot find a PCI board.
Action:
Installing a PCI board that bridges two system PCI buses (certain adapter boards provide this feature) can cause
previously installed PCI drivers not to recognize the respective adapter board(s).
To resolve the configuration problem, move the PCI board that has bridging capability to a PCI slot earlier in
the boot order.
Symptom:
•
The configuration cannot be saved and the battery loses power.
Action:
Refer to this section if the server frequently loses date and time that may be caused by the battery losing power.
