Battery usage time
Batteries are replacement items and over time the battery’s
capacity to hold a charge and its power level is reduced. If a
battery can only hold its charge for half of the time that it could
when new, it is recommended to purchase a new, replacement
battery.
When not using the battery for extended periods, charge the
battery to 30-40% of full charge before storing it. This extends
battery life.
Battery status
Move the cursor over the battery icon on the taskbar to view the
current battery charge when disconnecting the AC adapter from
the computer.
