Power Failures
You turn on your LIFE-
BOOK Tablet PC and
nothing seems to happen.
The installed battery is com-
pletely discharged or there is
no power adapter installed.
Check the Status Indicator Panel to determine the presence and condition of
the battery. See “Status Indicator Panel” on page 24. Install a charged battery
or a Power adapter.
The battery is installed but is
faulty.
Use the Status Indicator panel to verify the presence and condition of the bat-
tery. See “Status Indicator Panel” on page 24. If the battery indicates a short,
remove it and
operate from another power source or replace that battery.
The battery is low. Check the Status Indicator Panel to determine the presence and condition of
the battery. See “Status Indicator Panel” on page 24. Use a Power adapter to
operate until a battery is charged or install a charged battery.
The power adapter is not
plugged in properly.
Verify that your adapter is connected correctly. See “Power Sources” on
page 58.
The power adapter (AC or
auto/airline) has no power
from the AC outlet, airplane
jack, or car cigarette lighter.
Move the AC cord to a different outlet, check for a line switch or tripped circuit
breaker for the AC outlet. If you are using an auto/airline adapter in a car make
sure the ignition switch is in the On or Accessories position.
The power adapter (AC or
auto/airline) is faulty.
Try a different power adapter.
Your LIFEBOOK Tablet PC
turns off all by itself.
The power management
parameters are set for auto
timeouts which are too short
for your operating needs.
Press any button on the keyboard, or move the mouse. If that fails, push the
Power/Suspend/Resume slide. Check your power management settings, or
close your applications and go to the Power Options located in the Control
Panel to adjust the timeout values to better suit your needs.
You are operating on battery
power and ignored a low bat-
tery alarm until the battery
was at the dead battery state
and the system has entered
Dead Battery Suspend mode.
Install a power adapter, then push the Power/Suspend/Resume slide. See
“Power Sources” on page 58.
