86 Power Management Running the computer on battery power source, you may purchase a battery module for use in the computer's SelectBay, or carry additional charged battery packs with you. In addition to the main battery, the computer has two other batteries: the backup battery and the real-time-clock (RTC) battery. These are nickel metal hydride (NiMH) batteries. The backup battery provides the power to store information about the system when you suspend the computer using the Windows 95/Windows NT Suspend command, Windows 98 Standby command, or Toshiba's Resume Mode. The backup battery maintains this information for up to eight hours after the main battery discharges completely. The RTC battery powers the RTC memory that stores your system configuration settings and the current time and date information. It maintains this information for up to a month while the computer is turned off. Charging the batteries To charge the main battery while it is in your computer, plug the computer into a live wall socket. The battery charges whether the computer is on or off. It takes approximately two and a half hours to charge the battery with the computer off, or three and a half hours when the computer is on. The main battery light glows orange while the battery is being charged. The battery may not start charging immediately under the following conditions: ❖ The battery is extremely hot or cold. To ensure that the battery charges to its full capacity, wait until it reaches room temperature (50 to 80 degrees Fahrenheit, 10 to 30 degrees Celsius). Part I: Getting to Know Your Computer
