Troubleshooting Your Notebook

My notebook does not start.

Check that the notebook is plugged into a power source and that it is turned
on. Check that the power indicator on the notebook's front panel shows that
the power is on.
Check that the battery packs are inserted properly and that they are charged.
If you are connected to a docking station with a floppy disk drive or an
external floppy disk drive, make sure there is no floppy disk in the floppy
disk drive.
Confirm that the power cord and all cables are connected firmly, as
described in "Connecting a Power Source" on page 26.
If the notebook is plugged into a power strip or UPS, make sure the power
strip or UPS is turned on and working.
If you are using an external display, check that it is plugged into a power
source and turned on. Check that the brightness and contrast controls are
adjusted correctly. See the manual that came with your display for details.
Take the battery pack off the notebook, unplug the power cord and plug it in
again, then turn on the power.
If the power control button does not function, remove the AC adapter and
battery pack. Wait 1 minute, then reattach them, and press the power button.
Condensation may cause the notebook to malfunction. If this occurs, do not
use the notebook for at least 1 hour.

My notebook starts but a BIOS error appears.

When the internal backup battery is low on power, your system may not start
properly, and the message "Press <F1> to resume, <F2> to setup" may appear at
the bottom of the screen. Follow these steps:
1 Press the F2 key. The BIOS Setup menu appears.
2 Set the date (month/day/year). Press the Enter key.

Press the Enter key.
