Toshiba A10 User Manual

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 
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.

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 a CMOS error message 
during startup. The error message may vary by computer model.

Depending on your system, the RTC battery may only charge while 
the computer is turned on.

If the RTC battery is low, the real-time clock and calendar may 
display the incorrect time and date, or stop working.

To recharge the RTC battery, plug the computer into a live electrical 
outlet and leave the computer powered on for 24 hours.
