Batteries and Power Management Using Battery Power To respond to a low-battery warning The notebook automatically alerts you when the battery power drops to a critically low level. The notebook first emits a high-pitched beep or displays a warning message. Then, if you do not restore power within a short time, the notebook enters 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: Replace the battery with a charged one. Plug in the AC adapter. NOTE: If you plug in the AC adapter, you can continue to work while your battery recharges. For Intel Pentium 4 processors, speed denotes maximum performance mode on AC power. Processor speed on battery power is approximately 63.5 percent of maximum performance mode. For Mobile Intel Pentium 4 processors featuring Intel SpeedStep technology, speed denotes maximum performance mode. Battery optimization mode is approximately 80 percent of maximum performance mode. To recharge the battery CAUTION: The AC adapter is normally warm whenever plugged into an AC outlet. The notebook is normally warm while recharging. Don't recharge the notebook in a briefcase or other confined space, or the battery could overheat. Plug the AC adapter into the notebook. To get the longest operating time, wait until the battery charge is below 50 percent before recharging, and then charge it fully (100 percent). Charging can take up to 3 hours. If you continue working while the battery charges, the charging time may increase. The operating time for a fully charged battery depends on the notebook model, power management settings, and level of use. Startup Guide 25

Batteries and Power Management
Using Battery Power
To respond to a low-battery warning
The notebook automatically alerts you when the battery power drops to a critically
low level. The notebook first emits a high-pitched beep or displays a warning
message. Then, if you do not restore power within a short time, the notebook
enters 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:
Replace the battery with a charged one.
Plug in the AC adapter.
NOTE:
If you plug in the AC adapter, you can continue to work while your
battery recharges.
For Intel Pentium 4 processors, speed denotes maximum performance mode on
AC power. Processor speed on battery power is approximately 63.5 percent of
maximum performance mode. For Mobile Intel Pentium 4 processors featuring
Intel SpeedStep technology, speed denotes maximum performance mode. Battery
optimization mode is approximately 80 percent of maximum performance mode.
To recharge the battery
CAUTION: The AC adapter is normally warm whenever plugged into an AC
outlet. The notebook is normally warm while recharging. Don’t recharge the
notebook in a briefcase or other confined space, or the battery could overheat.
Plug the AC adapter into the notebook.
To get the longest operating time, wait until the battery charge is below 50 percent
before recharging, and then charge it fully (100 percent). Charging can take up to
3 hours. If you continue working while the battery charges, the charging time may
increase.
The operating time for a fully charged battery depends on the notebook model,
power management settings, and level of use.
