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 sho\
uld last:
Power management settings
l   
Hardware configurationl   
Software applicationsl   
Installed optionsl   
Display brightnessl   
Hard drive usagel   
Changes in operating temperaturel   
Type and number of installed PC Cardsl   
 
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: 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.l   
 
Maximizing the Energy Stored
To maximize the energy stored in the battery pack, follow these guidelin\
es: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.l   
 
Conditioning a Battery Pack
CAUTION:  To avoid a loss of data, ensure that all data is saved before di\
scharging a battery pack.
To condition a battery pack, complete the following steps:
Plug in the AC adapter and allow the battery to charge until the LED lig\
ht on the display stops blinking. 
Your battery gauge may read 100 percent for a period of time before LED \
light on the display stops 
blinking. Do not unplug the AC adapter until the arrow disappears.1.  
Unplug the AC adapter and allow the battery to drain until the computer \
reaches hibernation and turns 
itself off. Do not plug in the AC adapter during this process or you will need to re\
start with Step
No. 1.  You may use the computer while the battery is draining.2.  
Your battery is re- conditioned.3.  
Plug in the AC adapter and begin using the computer.4.  
  
 
The table below shows the approximate battery pack charge times:
Approximate Battery Charge Time
ComputerOn LineOff Line
NiMH Battery Pack4.0 hours premature termination2:00 hrs
Li ion BatteryPack4.5 hours premature termination2:50 hrs
 
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 be recycled. Battery p\
acks should be handled in accordance with country, 
state, province, or local regulations.
CAUTION:   Never attempt to open or service a battery pack. Opening a batte\
ry pack not only damages the
pack and makes it unusable, but also expose potentially harmful battery \
components.
