Storing a Battery Pack
CAUTION: to prevent damage to a battery pack, do not expose it to high temperatures for extended periods
of time.
If the computer will be unused and unplugged from an external power source for more than two weeks, remove and store
the battery packs.
Maximizing Battery Pack Life
Battery pack operating time varies depending on the system components, options, and applications used. Battery operating
time can increase by as much as 50% by controlling the energy used by the computer and the energy stored in the battery
pack.
To maximize battery pack life, use the following guidelines:
Initiate Suspend or Hibernation or turn the computer off when you are not using it.
●
Reduce the display brightness and select a shorter screen save timeout.●
Keep a battery pack in the computer when you are using the computer with external power.●
Disconnect external equipment that does not have its own power source (external equipment connected to the
computer drains the battery pack).
●
Exit modem programs when you are not using them.●
Remove a PC Card when you are not using it.●
When storing the computer for more than two weeks, remove battery packs and store them separately to reduce the
discharge rate and increase battery life.
●
Store the battery pack in a cool, dry place when it is not in use. High temperatures cause a battery pack to lose its
charge more quickly and reduce battery pack life.
●
Format diskettes while using external power when possible (formatting diskettes increases the drain on a battery
pack).
●
System Beeps
Beeps with a Blinking Battery Charge Light
When the computer beeps while the battery charge light is blinking, the computer has entered a low battery condition.
CAUTION: When you are alerted of a low battery condition, very little battery charge remains. Save your
information and take immediate action to resolve the low battery condition.
Selecting a Power Source
NOTE:
If your external monitor is not Energy Star compliant, enabling monitor energy-saving features may cause video
distortion when the screen save timeout occurs.
Resolving Low-Battery Conditions
If external power is available, do one of the following:
Connect the computer to an electrical outlet with the AC adapter.●
Dock the computer in a docking base that is connected to external power.●
Plug an optional automobile power adapter/charger into the power connector on the computer and into a vehicle●
