Tips for conserving battery power on
notebook PCs
|
|
|
|
You can manually change the power consumption of
your notebook PC and conserve battery power. |
|
|
|
- Reduce the brightness of the screen
to the minimum readable level. Use the
function keys on the top of your keyboard to adjust the
brightness.
- Remove peripherals when not in use.
External hard drives, CD-ROMs, Zip
drives, PC cards, and other peripheral
devices can draw power from your battery
even when they are not in active use.
Disconnect them when you have finished
using them.
- Turn off the Wireless On-Off
button when it is not in use. If
your notebook has one, press the
Wireless On-Off button so that the light
turns off.

Battery care practices
|
|
|
|
Battery cells suffer gradual, irreversible
capacity loss over time.
Such aging occurs more rapidly as temperature
and discharge loads increase. Here are some
suggested ways to minimize the capacity loss for
your battery. |
|
|
|
-
Store Li-Ion
batteries between 20°C and 25°C (68°F
and 77°F) with 50% to 70% charge.
-
Do not
leave batteries exposed to high
temperatures for extended periods. Prolonged exposure
to heat (for example, inside a hot car)
will accelerate the deterioration of
Li-Ion cells.
-
When storing your notebook
for longer than 1 month, HP recommends discharging your battery
to 50% and removing it from the system. Be sure to store at a
reasonable room temperature (~25°C). If storing for more extended
periods, it is recommended to recharge the battery to 50% every 6
months or so.
|
Special notes for embedded (non user replaceable) batteries: |
-
If the notebook will be unused for more
than 3 months, discharge the battery to approximately 70% before
storing. For prolonged storage, check the battery capacity every 6
months and charge back up to 70%. Always store the notebook between
20°C and 25°C (68°F and 77°F).
-
If the notebook is used primarily on AC
power, allow the battery to discharge completely and recharge once
per month.
| Note: Recommendations for battery use and
storage are covered in the HP User Guides for
each model. |
