Procedure
The battery may be discharged - connect the AC
adaptor to recharge the battery.
If the battery is completely discharged, it will not
begin charging immediately, in these instances
you should wait a few minutes before trying again.
If the battery still does not charge, you should
check that the power outlet the AC adaptor is
connected to is supplying power - this can be
tested by plugging another appliance into it.
Check whether the battery is hot or cold to the
touch - if so, it will not charge properly and should
be allowed to reach room temperature before
you try again.
Unplug the AC adaptor and remove the battery to
make sure its connecting terminals are clean – if
necessary wipe them with a soft dry cloth lightly
dipped in alcohol.
Connect the AC adaptor and replace the battery,
taking care to ensure that it is securely seated in
the computer. Allow the battery to charge for at
least twenty minutes.
Check the DC IN/Battery indicator - if it glows
amber, charge the battery until the DC IN/Battery
indicator glows white.
If it glows white, disconnect the AC adaptor and
operate the computer. If the computer shuts down,
the battery may be at the end of its operating life
and should be replaced. However, if you do not
believe the battery is at the end of its operating
life, you should contact a TOSHIBA Support.
If you frequently recharge a partially charged
battery, the battery might not charge to its full
potential - in these instances you should fully
discharge the battery and then attempt to charge
it again.
Check the Power saver option under Select a
power plan in the Power Options.
