Charging The Batteries; Charging Time; Battery Charging Notice - Toshiba Satellite L50-B User Manual

Charge the battery pack only in an ambient temperature from 5 through 35
degrees Celsius. Otherwise, the electrolyte solution might leak, battery
pack performance might deteriorate, and the battery life might be
shortened.

Charging the batteries

When the power in the battery pack becomes low, the DC IN/Battery
indicator flashes amber to indicate that only a few minutes of battery power
remain. If you continue to use the computer while the DC IN/Battery
indicator flashes, the computer enters Hibernation Mode so that you do not
lose any data, and automatically turn itself off.
You must recharge a battery pack when it becomes discharged.
Procedures
To recharge a battery pack, connect the AC adaptor to the DC IN 19V jack
and plug the other end into a working outlet. The DC IN/Battery indicator
glows amber while the battery is being charged.
