Trouble when Starting
Why doesn't the power indicator or the battery indicator turn on?
• Make sure the AC adapter is correctly connected to the AC adapter jack of your
computer.
• Make sure the AC power cable is correctly connected to a live wall outlet. To find
it is live or not, connect another electric equipment to the wall outlet.
• Make sure the battery pack is correctly installed and charged.
• If the battery pack is discharged, connect the AC adapter.
• If all the steps above failed, follow the instructions on Why doesn't the keyboard or
the touchpad respond to your operation? on page T-3.
Why do I get the message Invalid system disk?
• You may have inserted a non-bootable disk (either a defective disk or one without
an installed operating system) in the optional external floppy disk drive unit. Eject
the disk.
Why can’t I boot from the floppy disk?
• Make sure that the optional external floppy disk drive unit is correctly connected to
your computer.
• Check whether the floppy disk set to the optional external floppy disk drive unit
contains a system disk.
• Check whether USB Boot in the Boot menu of the Setup Utility is enabled. (Refer
to the Boot Menu section on page 5-7.)
• Check whether Floppy Disk Drive is at the top in the Boot Sequence in the Boot
menu of the Setup Utility. (Refer to the Boot Menu section on page 5-7.)
Why do I get the message Operating System not found?
• The message may appear when the installation has failed. Recover the C and D
drives using the created recovery CDs.
