Problems when you turn on the computer
3 Connect the AC adaptor to the computer. Leave the
battery out of the computer. Try turning the computer on
again.
If the computer starts normally, the battery may need
charging, may be depleted, or may be defective. Turn the
computer on, insert the battery, and then leave the
computer running for several hours, which will deliver a
slow, steady "trickle-charge" to the battery. Once the
battery has been trickle-charged, it may begin working
correctly again.
If the trickle-charging does not prove effective, visit the
Toshiba Web site at
Support Bulletin Step-Charging the computer's
battery (click the Ask Iris
support bulletin by name).
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.
