CAUTION: To avoid a loss of data, ensure that
all data is saved before discharging a battery
pack.
To condition a battery pack, complete the following steps:
1. Allow the battery to drain until the computer reaches hibernation and
turns itself off. Do not plug in the AC adapter during this process.
Also, the system should not be allowed to sleep. To prevent sleep, you
may either use the computer while the battery is draining, or you may
disable power management.
2. Plug in the AC adapter and allow the battery to charge until the LED
light 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.
Your battery is now re-conditioned, and you may begin using the computer
normally.
The battery pack charge time may vary greatly from 2 hours to 5 hours or more,
depending on many factors (including whether it is charged on-line or off-line).
Disposal of a Used Battery Pack
In the interest of safeguarding our environment. Compaq Computer Corporation
recommends that nickel metal hydride (NiMH) and lithium ion (Li ion) battery packs
be 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 pack not only damages the pack and makes it
unusable, but also expose potentially harmful battery
components.
