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.
