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 front panel of the notebook
indicates that the power is on.
❑ Check that the battery packs are inserted properly and that they are charged.
❑ If you have connected an external, optional 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 the “Connecting a Power Source” section of the printed Quick
Start.
❑ If you plugged the notebook into a power strip or Uninterruptible Power
Supply (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 the display for details.
❑ Condensation may cause the notebook to malfunction. If this occurs, do not
use it for at least one hour.
❑ Take the battery pack out of the notebook, unplug the power cord, plug it in
again, and then turn on the power.
My notebook starts but a BIOS error appears.
❑ When the internal backup battery is low on power, it may not start your
system properly. The message, “Press <F1> to resume, <F2> to setup”
appears at the bottom of the screen. Follow these steps:
