About the computer and software
My computer does not start
❑
Check that the battery pack is inserted properly and that it is charged. If it is and you still cannot start
the computer, take out the battery and make sure your computer is running on the AC power supply
only.
❑
Check that the computer is plugged directly into a power source (without an extension cord) and that it
is turned on.
❑
Check the power socket is working by testing it with another device (e.g. a lamp or radio).
❑
Check that the power indicator on the front panel of the computer indicates that the power is on.
❑
Check that you are using the supplied Sony AC adapter.
❑
Check cables for signs of wear and tear (which can occur if the cable is twisted around the AC adapter
during transport).
❑
If you cannot start Windows
®
, make sure there is no disk in the floppy disk drive.
❑
Confirm that the power cord and all cables are connected firmly.
❑
If you have plugged the computer into a UPS (Uninterruptible Power Supply), make sure the UPS is
turned on and works.
❑
Unplug all external devices and cables, including the Internet connection.
❑
Remove any extra memory modules you may have inserted since purchase.
❑
If you are using an external display, check that it is plugged into a power source and turned on. Check
that you have switched to the external display and that the brightness and contrast controls are adjusted
correctly.
❑
Moisture condensation may have occurred. Do not use the computer for at least one hour and then turn
it on.
❑
If the message
Press <F1> to resume, <F2> to set up
appears at the bottom of the display, you need
to initialise the BIOS (Basic Input/Output System).
