To Recharge The Battery; To Get The Most From Your Batteries - HP Pavilion XF315 Reference Manual

Note
CAUTION
Batteries and Power Management
Using Battery Power
Once the notebook enters hibernation in this way, you won't be able to turn it on again
until you restore power by doing one of the following:
• Connect the AC adapter (see "Step 2: Connect AC power" on page 22).
• Replace the battery with one that is charged (see "Step 1: Install the battery" on page
20).
If you connect the AC adapter, you can continue to work while your battery recharges.

To recharge the battery

The AC adapter is normally warm whenever plugged into an AC outlet. The
notebook's battery is normally warm while recharging. Do not recharge the
notebook in a briefcase or other confined space, or its battery could overheat.
• To recharge the battery, connect the AC adapter to the notebook.
To get the longest operating time, wait until the battery's charge is below 20% before
recharging, then charge it fully (100%). You can continue working while the battery
charges.

To get the most from your batteries

Follow these suggestions to make your battery's power last as long as possible.
• Connect the AC adapter, especially while using the CD/DVD drive or any external
connection such as a PC card, modem, or floppy disk drive.
• Set the display brightness to the lowest comfortable level (Fn+F1).
• Put the notebook on standby whenever you will not be using it for up to several hours.
• Put the notebook into hibernation whenever you want to save your current session, but
will not be using the notebook for a day or more.
• Set the automatic timeout settings to emphasize saving power—see "How the
notebook manages power automatically" on page 48.
• If you have an I/O PC card—that is, a PC card having an external connection, such as
a network card—remove it when you're not using it. Some I/O cards use significant
power even when inactive.
