❑Check that the battery packs are inserted properly and are charged.

❑If you are connected to a docking station with a floppy disk drive or an external floppy disk drive, make sure the floppy disk drive is empty.

❑Confirm that the power cord and all cables are connected firmly, as described in the section “Connecting a Power Source” of your printed Quick Start.

❑If the computer 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.
