Before running POST, complete the following preliminary steps:
IMPORTANT: Use AC power when running POST or Computer Setup. A low 
battery condition could initiate Hibernation and interrupt the 
test.
Obtain established passwords. For information on clearing passwords,
click  here.
1.  
Ensure that the hard drive is installed in the computer.2.  
Ensure that the battery pack is installed in the computer and the power 
cord is connected to the computer and plugged into an AC power 
source.3.  
Turn on the computer.4.  
If a power-on password has been established, type the password and 
press  Enter.5.  
Run Computer Setup. If a Setup password has been established, type 
the password and press  Enter.6.  
Turn off the computer and all external devices.7.  
Disconnect external devices that you do not want to test. If you want 
to use the printer to log error messages, leave it connected to the 
computer.8.  
Use Compaq Utilities and loopback plugs in the serial and parallel 
connectors if you plan to test these ports.9.  
NOTE: If a problem only occurs when an external device is connected to the 
computer, the problem could be with the external device or its cable. 
Isolate the problem by running POST with and without the external 
device connected.
Follow these steps to run Compaq Utilities: If you are running Compaq Utilities from the hard drive, turn on or 
restart the computer. Press  F10 when the cursor appears in the
upper-right corner of the screen. If you do not press  F10 in time,
restart the computer and try again.
l   
If you are running Compaq Utilities from diskette, insert the Compaq 
Utilities diskette in drive Turn on or restart the computer.l   
Press  Enter to accept.l    
						

							Select Prompted  Diagnostics .l   
After Identifying System Hardware  completes, select Interactive
Testing  and follow the instructions on the screen.l   
When the preliminary steps are completed, you are ready to run  POST.

Compaq
The Power-On Self-Test (POST) is a series of tests that run everytime the computer is turned on. POST verifies that the system is configured and functioning properly.
To run POST, complete the following steps:
Complete the  Preliminary steps .1.  
Turn on the computer.2.  
If POST does not detect any errors, the computer beeps once or twice to 
indicate that POST has run successfully. The computer boots from the har\
d
drive or from a bootable diskette if one is installed in the diskette dr\
ive.
POST Error Messages
If the system is not functioning well enough to run POST, or if the disp\
lay is
not functioning well enough to show POST error messages, refer to the
Troubleshooting tables in the  Troubleshooting without Diagnostics  page.
If POST detects an error, one of the following events occurs: A message with the prefix WARNING appears, informing you where 
the error occurred. The system pauses until you press  F1 to continue.
1.  
A message with the prefix FATAL appears, informing you where the
error occurred. After the message, the system emits a series of beeps,
then stops.2.  
The system emits a series of beeps, then stops.3.  
Warning messages indicate that a potential problem, such as a system
configuration error, exists. When  F1 is pressed, the system should resume.
You should be able to correct problems that produce  WARNING messages.
If you receive one of the error messages listed below, follow the recommended action.
