8·8 Troubleshooting
Portable PLUS Computer
18. Follow Up.
Take action according to the results of each test:
•
If
no problems occur, the tested functions are probably good
and
no
action
is
required. Check
the last three items listed below. (However,
if
the customer indicates a problem
and
you
haven't found anything so far, consider whether another function might be
involved-then
test
tl/at function.
If
you think that a test might be missing the problem, check the unit using the
oscilloscope routines described in section 8.3.)
•
If
a test
does
indicate a problem, replace the assembly or component indicated
by
the test.
(Refer to table 8·2 for specific information.) Then repeat the test to ensure that the problem has
been repaired.
•
If
a test doesn't operate properly, check the unit using the built-in diagnostic test
menu
(figure
8-2) instead of the disc-based menu.
If
the built-in tests
don't
operate, check the unit according
to table 8-5, "Startup Problems:
• Modem: If a modem
is
installed, verify that its presence is noted. If the message '
No
modem
installed" appears, check the unit according
to
table 8-11, 'Repairing the
Modem:
If
you're using the built-in modem test, look for a "bad device" message with no failure code.
If
this occurs, take action according to the "3??' failure code.
• Memory Drawer:
If
a memory drawer
is
installed, verify that its presence is noted ('Receptacle
11
: testing
xxxK
RAM
'). Receptacle 1
is
under the ( Return) key; receptacle 2
is
under
the
(ill
key.
Also verify that the amount of
RAM
indicated by the test message ('xx
xK
RAM")
is
the
same
as
the amount of memory in the drawer. If there
is
a problem, swap the
RAM
PCA (or piggy-back
PCA,
if
installed) in the drawer.
• Software Drawer:
If
a software drawer
is
installed, verify that the list of occupied ROM sockets
is
correct (,Receptacle
11:
The following ROM(s) were found
..
:)
. Receptacle 1
is
under
the
( Return) key; receptacle 2
is
under
the
(ill
key.
If
all
of the ROM ICs aren't found,
swap
the
ROM PCA in the drawer. If
some
ROM
ICs aren't found, swap good
ROM
ICs in those loca-
tions. (Also check the jumper positions on the
PCA-refer
to table 8-4.) Replace the ROM PCA
or the ROM ICs, as indicated. (For a SNALink/3270 software drawer, refer to section 8.6.)
Verification:
19.
Verify Operation. After repairing any faults, verify that the unit
is
good by repeating steps 13
thru 18 above. In step 17, select the complete system test (press
(ill
in the disccbased test menu).
Recall that the HP-IL, RS-232-C,
and
modem tests require certain connections
at
the appropriate
receptacles (refer to step 17 above).
20. Set Time. Set the time zone
and
time to their correct values: press
@)
(Time & Date Config) in
the main
PAM
screen. Move thru the menu using the tab or cursor keys. Change entries as
needed by pressing the
'Next
Choice" or 'Previous Choice' keys. Press the 'Exit Config" key to
save the time you've selected.
21. Format and Restore Edisc. Format the Edisc (also called drive
A).
Use the File Manager
program's 'Format" option, specifying
a:
as the drive.
Copy the old Edisc contents back into the computer from the external disc. Use the File Manager
program's ' Copy File' option. (The procedure for copying
an
entire disc is explained in chapter 5
of
Using
tire
Portable
PLUS.)
22. Recharge the Battery.
If
power has been disconnected from the unit, the battery
'gauge'
resets
to 0 percent, even though the battery may not be at that level. Connect the unit to a recharger
and
allow the battery to charge for
at
least 12 hours while the unit is
turned
off. This will
return
the
'gauge'
and
battery to at least
95
percent (of full charge). Alternatively, include a note to the
customer suggesting recharging the battery until the
'gauge'
reaches 95 percent.
This completes the main diagnostic procedure.
