plug fits correctly in the DC-IN socket. The labels on the 
bottom of the computer and the AC adaptor show the 
specifications for voltage ("V") and current ("A") for each 
device. The voltage level must match exactly. The amperage 
rating of the AC adaptor must be equal to or greater than that 
required by the computer.

If the battery light is blinking when the computer is on, this 
indicates a power mismatch. Do the following:

Check the OUTPUT specifications on the AC adaptor (for 
example, DC 19V – 3.95A)

Check the INPUT specifications on the bottom of the 
computer. 

The output specifications of the AC adaptor must match the 
input specifications of the computer. 

If the specifications do not match, locate and use the AC 
adaptor that shipped with your computer. If the specifications 
do match, contact Toshiba. See

Once you are familiar with the desktop and used to the way the 
operating system responds to your work routine, you can easily 
detect if the operating system is not working correctly. For 
example:

❖

The operating system fails to start after the initial startup 
appears.

❖

The operating system takes a long time to start.

❖

The operating system responds differently from the normal 
routine.

❖

The screen does not look right.

Unless a hardware device has failed, problems usually occur when 
you change the system in some way such as installing a new 
program or adding a device.

If you experience any of these problems, use the options in the 
Startup menu to fix the problem.
