to around 5% of total charge. At this point,
without warning
, the
notebook will automatically save to disk and turn off the system.
After this occurs, you cannot restart your notebook until you have
connected the AC adapter, or installed a new charged battery. The
save to disk procedure ensures that no data is lost. When your
notebook is restarted, your work will appear exactly as it was when the
save to disk procedure occurred.
Battery Conditioning
In everyday use, you will probably charge your battery every time you
are using AC power. This is convenient, but each time you charge the
battery before it is fully discharged, it causes the battery to store slightly
less charge than is possible. Irregular charging and discharging also
causes the calibration of the Windows battery gauge to become
inaccurate.
To correct these problems, carry out the battery conditioning sequence
described below. Try to do this at least once or twice a month.
Install the battery pack in the right device bay.
Connect your notebook to an AC power supply. With the notebook
turned on or off, allow the battery to become fully charged. Disconnect
the AC adapter and leave the notebook turned on until it completely
discharges and saves to disk.
Reconnect the AC adapter, and allow the battery to fully charge.
You might need to repeat steps 1 to 3 again in order to fully calibrate
the Windows battery gauge.
Even if you maintain the battery in good condition, it will slowly
deteriorate, and store less and less charge. You might begin to notice
this after about 500 cycles of charging and discharging. We
recommend that you replace your battery when it no longer stores a
useful amount of charge.
Using Power Management
When you are running your notebook from the internal battery, it is
important that you use the power management routines to reduce the
system power consumption. You can also adopt some simple practices
in your use of the notebook that can help to extend the useful
computing time you get from a charged battery.
