Notebooks. To isolate problems while troubleshooting the Notebook, refer to the following
procedures:
1. Preliminary Steps
2. Power-On Self-Test (POST
.
).
3. Test the recommended actions described in the diagnostic tables if POST is unavailable or if
POST displays an error message.
When following the recommended actions in the Sections about the Power-On Self-Test (POST)
Diagnostic Error Codes
, perform the steps in the order listed. Rerun POST after each recommended
and
action until the problem is solved or no error messages occur. Once the problem is solved, do not

Preliminary Steps
Before running the Power-On Self-Test (POST), complete the following steps:
1. If a Power-on password has been established, type the password and press the Enter key. If
the password is unknown, clear the password (See Clearing the Power-On Password
).
2. Run the Computer Checkup (TEST)
.
3. Turn off the Notebook and all external devices.
4. Disconnect any external device that does not need testing. Do not disconnect the printer if it
needs testing or if it is required to log error messages.
Important: If the problem only occurs when an external device is connected to the
Notebook, the problem may be related to the external device or its cable. Check this by
running POST both with and without the external device connected.
5. Install loopback plugs in the serial and parallel connectors if these ports need testing.
6. Ensure that the hard drive is installed in the Notebook.
7. Ensure that the battery pack is inserted into the Notebook, and that it is connected to an
external AC power source.
When these preliminary steps are completed, run the Power-on Self-Test (POST)
.
