If you wait for a while and the computer screen remains blank, restart your
VAIO computer by following the procedures below in order. Note that following
these procedures may cause working data to become corrupted.
Disconnect all peripheral devices, such as a printer or a USB device, and your
VAIO computer from the network, if any.
Press and hold down the
(Power) button for more than four seconds and make
sure the power indicator light is off. Then, turn on your VAIO computer again.
If the problem persists, press and hold down the (Power) button for more
than four seconds and make sure the power indicator light is off. Disconnect all
cables connected to your VAIO computer, such as the AC adapter, remove the
battery pack, and wait about five minutes. Then, put all cables, peripheral
devices, and the battery pack back in place and turn on the computer again.
If an extra memory module is not installed properly, your VAIO computer may
not turn on.
Use of memory modules not specified by Sony or improper installation of
memory modules may cause the computer to fail to boot or to become
unstable. In such a case, reinstall the memory module.
If you use a memory module other than the Sony branded memory module,
contact the sales dealer or the manufacturer of the memory module.
If you bring your VAIO computer directly from a cold location to a warm one, or
use it in a high humidity location, moisture may condense inside the computer.
In such a case, allow at least one hour before turning on the computer.
Do not use the computer in a high humidity location (a relative humidity of
more than 80 %), as it may cause the computer to malfunction.
