To Respond To A Low-Battery Warning; To Recharge The Battery - HP Pavilion XF315 Startup Manual

Note
CAUTION

To respond to a low-battery warning

The notebook automatically alerts you when battery power drops to a critically low level.
If you do not restore power within a short time, the system goes into hibernation.
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 19).
• Replace the battery with one that is charged (see "Step 1: Install the battery" on page
17).
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.
