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. 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 and external disk drives. How much charge the battery contained to begin with. How you use optional devices, such as a USB device, 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. Whether you close the display panel when you are not using the keyboard - closing the display saves power. The environmental temperature - operating time decreases at low temperatures. Batteries exhausted time When you turn off the power of your computer with batteries fully charged, the batteries will be exhausted within the following approximate period (in tablet mode).

older battery will not operate for as long as a new battery even when
both are fully charged.
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 and external
disk drives.
How much charge the battery contained to begin with.
How you use optional devices, such as a USB device, 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.
Whether you close the display panel when you are not using the
keyboard - closing the display saves power.
The environmental temperature - operating time decreases at low
temperatures.
