120 Mobile Computing Charging the batteries computer off. It takes much longer to charge the battery while the computer is on. TECHNICAL NOTE: The battery does not charge while the computer is consuming full power. The battery may not start charging immediately if: ❖ 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 26 degrees Celsius). ❖ The battery is almost completely discharged. Leave the power connected, and the battery should begin charging after a few minutes. HINT: Once the battery is fully charged, we recommend that you operate your computer on battery power until the battery discharges completely. Doing this extends battery life and helps ensure accurate monitoring of battery capacity. Charging the RTC battery Your computer has an internal real-time clock (RTC) battery. The RTC battery powers the System Time Clock and BIOS memory used to store your computer's configuration settings. When fully charged it maintains this information for up to a month when the computer is powered off. The RTC battery may have become completely discharged while your computer was shipped, resulting in the following error message during startup: BAD RTC BATTERY BAD CHECKSUM (CMOS) CHECK SYSTEM
