I cannot print
❑

The default setting for the printer port mode is correct for most 
printers. If you cannot print, try changing the printer port mode. In 
Sony Notebook Setup, select the Printer tab. If the printer port mode 
is set to ECP, change it to bidirectional. If the printer port mode is set 
to bidirectional, change it to ECP. See “Displaying the Sony Notebook 
Setup Screen” in the online document Customizing Your VAIO

Notebook for details on using Sony Notebook Setup.

❑

Your connected printer may not function after the computer resumes 
from a power-saving mode. When this occurs, follow the procedures 
below to reset the printer connection:

1

Right-click the My Computer icon on the desktop, and then select 
Properties.

2

Click the Device Manager tab.

3

Select Refresh, and then click OK. The printer should now 
function properly.

Power Management

The operating system may become unstable if a lower power state such as 
system hibernation is initiated and then changed before the operating 
system completely enters the lower power state. To restore the computer 
to its normal operating stability, close all open applications, press the 
power button, and hold it for four seconds or more to completely shut 
down the computer.
