4 Connect the AC adaptor to a different power outlet, preferably
in a different room. If the computer starts normally, there may
be a problem with the AC outlet itself, or the voltage level
available from it.
5 Verify that the AC adaptor is the correct unit for your computer
model. The computer may not be able to start from an AC
adaptor that is rated for less current (amperage) than the
computer requires, even if the rated voltage is correct, and the
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.
The battery light is blinking when the computer is on.
If the battery light is blinking when the computer is on, this
indicates a power mismatch. Do the following:
1 Check the OUTPUT specifications on the AC adaptor
(for example, DC 19V – 3.95A)
2 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.
3 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 “Contacting Toshiba” on
page 168.

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.
