Determining Remaining Battery Power; What To Do When The Main Battery Runs Low - Toshiba PORTEGE R500 Series User Manual

Determining remaining battery power

NOTE
1 Click Start, Control Panel, Performance and Maintenance,
and then TOSHIBA Power Saver.
2 Click the TOSHIBA Power Saver icon.
The Power Saver Properties window appears.
The remaining battery charge is indicated on the left side of the
dialog box.
With repeated discharges and recharges, the battery's capacity
gradually decreases. A frequently used older battery does not
power the computer for as long as a new battery, even when
both are fully charged.

What to do when the main battery runs low

When the main battery runs low you can:
❖
Plug the computer into an external power source and recharge
the main battery
❖
Place the computer into Hibernation mode and replace the
main battery with a charged spare
❖
Connect the computer to an optional high secondary battery (if
available for your computer)
❖
Save your work and turn off the computer
Monitoring main battery power
Wait at least 16 seconds after turning on the computer before trying
to monitor the remaining battery power. The computer needs this
time to check the battery's remaining capacity and perform its
calculations.
TECHNICAL NOTE: The computer drains the battery faster at low
temperatures. Check your remaining charge frequently if you are
working in temperatures below 50 degrees Fahrenheit.
The computer calculates the remaining battery charge based on your
current rate of power use and other factors such as the age of the
battery.
