Commands for toggling test settings
The following table describes the various commands used to toggle test settings within the
diagnostics program.

Table 6 - Diagnostic Commands for Toggling Settings

Command Description
Ctrl+C Toggle battery Charging on/off. This command sends a request to the charging
software in the BIOS to enable charging / disable charging.
Ctrl+E Toggle ignore Errors on/off (continue after error when on). Normally Diag stops
looping when an error occurs, but with this command, Diag will continue to loop
until all requested loops are complete.
Ctrl+L Toggle Logging to disk file (errors, all, all+status, none). This command appends
results to the file DIAG.LOG on the current drive and directory from which Diag
was run. The data logged is either: 1) only tests which fail, 2) all tests results, 3)
all test results, and all messages shown in the lower status window, or 4) none.
For looping tests, the loop count and time is logged at the start of each loop. If a
floppy or hard disk critical error happens when logging results, the normal "Abort,
Retry, Ignore" message may not be visible depending on the display mode. A
special error handler has been incorporated into diag to handle this case. A
flashing message will appear on the top line should an error of this type occur.
Press A, R, or I to continue. If no keyboard is available, press the Contrast Up
button to Retry, or the contrast Down button to Ignore the error.
Ctrl+N Toggle Noise (beep & flash) at test completion. When a test or set of tests
completes, Diag waits for the user to enter more commands. To help notify the
operator of when this happens, use Ctrl+N to cause Diag to invert the display and
sound a noise until the user responds in some way.
Ctrl+P Toggle Power management on/off. Tests that require measuring power levels
may require that Power management be on or off. This can be controlled directly
with this command.
Ctrl+T Toggle between the four types of mouse tests. The HP mouse tests are 1) text
mode mouse test, 2) graphic mode sine wave mouse test, 3) combined text and
sine tests, and 4) graphic draw mode test.
Ctrl+V Toggle Verbose test status reporting. Some tests can report more detailed
information. These tests include: all dock related tests (reports voltages), the HP
and External mouse tests (reports x/y data and button status).
Ctrl+W Toggle printing to Wired serial port (errors, all, all+status, none). Like the
<Ctrl+L> command that logs results to disk, this command similarly logs results to
the com 1 serial port.
Alt+A Toggle cAche on/off. If it is necessary to disable the cache, use this command.
Processor level commands are used to perform this operation.
Alt+K Toggle miKe on & line off, mike off & line on, both off.
Alt+M Toggle program control with Mouse on or off. Like the -m command line option,
Alt+M enables controlling Diag with a mouse. The mouse actions listed below
have the following keyboard equivalents:
