Determining Battery Health
There are several methods of determining your battery’s capacity relative to
it’s initial specification (aka “health”).
* Press and hold the status button located on the bottom of your laptop
battery. The five LED lights will initially display your battery’s current
charge (five lights is charged, zero lights is discharged), and if you
continue pressing the status button for three seconds the lights will blink
off and back on again, now displaying the health of your battery. If zero
lights appear your battery is operating at greater than 80% of its specified
capacity, if five lights appear your battery is operating at less than 60% of
its specified capacity. This information was pulled from the D620 User Guide.
* If you enter the system BIOS by pressing “F2″ during the Dell logo while
booting, there is a “Battery Health” option under the “Sytem” menu which
gives a qualitative assessment of battery health.
* The power manager under FC6 tracks the maximum capacity of your dell d620
battery at its last full charge and generates a health percentage based on the
factory spec charge for your battery. To view this information, right-click
the battery meter in your gnome panel, select “Information”, and expand the
“More” area of the “Device Information” panel.
* If you kept your initial Windows XP install, there is a battery health meter
under the Dell Quickset applet in the lower right hand corner of the screen
that gives the same information that is available through the system BIOS.
