then returns you to your previous work session without restarting your
computer.

lose data.

Windows Power Options or Dell QuickSet, use one of the following

To exit Sleep state, press the power button.
Charging the Battery
NOTE:
Charge time is longer with the computer turned on. You can leave the
battery in the computer for as long as you like. The battery’s internal circuitry
prevents the battery from overcharging.
When you connect the computer to an electrical outlet or install a battery
while the computer is connected to an electrical outlet, the computer checks
the battery charge and temperature. If necessary, the AC adapter then charges
the battery and maintains the battery charge.
If the battery is hot from being used in your computer or being in a hot
environment, the battery may not charge when you connect the computer to
an electrical outlet.
