This section covers troubleshooting information for the 
Compaq Presario 1200 Series Portable Computers. The 
basic steps in troubleshooting include:
1. Follow the 
Preliminary Steps.
2. Run the 
Power-On Self-Test 
(POST).
3. Follow the recommended 
actions described in the 
diagnostic tables, if you are 
unable to run POST or if POST 
displays an error message.
When following the recommended 
actions in the Sections on POST 
and 
Diagnostic Error Codes 
perform them in the order listed. 
Rerun POST after each 
recommended action until the 
problem is solved and no error 
message occurs. Once the 
problem is solved, do not 
complete the remaining 
recommended actions.
NOTE:
If the problem is 
intermittent, check the 
computer several times to 
verify that the problem is 
solved.

Battery Pack Operating Time
This appendix covers the following information concerning battery pack o\
perating time:
l     Increase battery pack operating time
l     Conditioning a battery pack
l     Disposal of a used battery pack
Increasing Battery Pack Operating Time
Battery pack operating time differs depending on several variables. To a\
void unnecessary 
replacement, consider the following variables when determining how long \
a charged battery pack 
should last:
l     Power management settings
l     Hardware configuration
l     Software applications
l     Installed options
l     Display brightness
l     Hard drive usage
l     Changes in operating temperature
l     Type and number of installed PC Cards
NOTE:The power consumption requirements for PC Cards vary widely. Some cards \
drain 
the battery pack very rapidly.
Battery pack operating time can be increased by as much as 50 percent by\
 controlling the energy 
required by the computer and the energy stored in the battery pack.
Minimizing the Energy Required
To minimize the energy required by the computer, follow these steps:
l     Set the power conservation levels in the Power Management utility to Maximum.
l     Customize the timeout value to work more efficiently with the applicatio\
ns. The 
amount of battery life depends on the values selected.
 
Maximizing the Energy Stored
To maximize the energy stored in the battery pack, follow these guidelin\
es:
l     Condition the battery pack at least every 30 days to improve overall bat\
tery 
performance.
l     Keep a battery pack in the computer when using it with AC power to suppl\
y the 
battery pack with a constant trickle charge.
l     Store the battery pack in a cool, dry place when not in use.
 
Conditioning a Battery Pack
CAUTION:  To avoid a loss of data, ensure that all data is saved before discharg\
ing a 
battery pack.
 To condition a battery pack, complete the following steps: 1. Plug in the AC adapter and allow the battery to charge until the fast\
 charge arrow on 
the display disappears. Your battery gauge may read 100 percent for a pe\
riod of time 
before the arrow disappears. Do not unplug the AC adapter until the arro\
w disappears.
2. Unplug the AC adapter and allow the battery to drain until the comput\
er reaches 
hibernation and turns itself off. Do not plug in the AC adapter during this process 
or you will need to restart with Step No. 1. You may use the computer while the 
battery is draining.
3. Your battery is re- conditioned.
4. Plug in the AC adapter and begin using the computer. 
The table below shows battery pack charge times by model.
 
Battery Charge Time
Computer On Line Off Line
Model 1/NiMH Battery Pack 4.0 hours premature termination 2:00 hr
Model 2/Li ion Battery Pack  4.5 hours premature termination 2:50 hr
Disposal of a Used Battery Pack
In the interest of safeguarding our environment. Compaq Computer Corpora\
tion recommends that 
nickel metal hydride (NiMH) and lithium ion (Li ion) battery packs b\
e recycled. Battery packs 
should be handled in accordance with country, state, province, or local \
regulations.
CAUTION:  Never attempt to open or service a battery pack. Opening a battery pac\
k 
not only damages the pack and makes it unusable, but also expose potenti\
ally harmful 
battery components.
