L500/L505/L500D/L505D In such cases you should follow the steps as detailed below: 1. Fully discharge the battery by leaving it in the computer with the power on until the system automatically turns itself off. 2. Connect the AC adaptor to the DC IN 19V jack of the computer, and to a wall outlet that is supplying power. 3. Charge the battery until the Battery indicator glows white. Repeat these steps two or three times until the battery recovers normal capacity.

■
Clicking the battery icon on the task bar
■
Via the Battery Status in the Windows Mobility Center window
Maximizing battery operating time
A battery’s usefulness depends on how long it can supply power on a
single charge, while how long the charge lasts in a battery depends on:
■
Processor speed
■
Screen brightness
■
System Sleep Mode
■
System Hibernation Mode
■
Display power off period
■
Hard disk drive power off period
■
How often and for how long you use the hard disk drive, optical disc and
floppy diskette drives.
■
How much charge the battery contained to begin with.
■
How you use optional devices, such as a PC Card, to which the battery
supplies power.
■
Whether you enable Sleep Mode, which can conserve battery power if
you are frequently turning the computer off and on.
■
Where you store your programs and data.
■
You should wait at least 16 seconds after turning on the computer
before trying to monitor the remaining operating time. This is because
the computer needs this time to check the battery’s remaining capacity
and then calculate the remaining operating time, based on this together
with the current power consumption.
■
Please be aware that the actual remaining operating time may differ
slightly from the calculated time.
■
With repeated discharges and recharges, the battery’s capacity will
gradually decrease. In view of this it will be noted that an often used,
older battery will not operate for as long as a new battery even when
both are fully charged.
