To charge the battery, leave the computer plugged into a live wall outlet for several hours. For more information see “Charging batteries” on page 108. The AC power light is blinking. If the AC power light is blinking, try the following steps: 1 Cut off power to the computer by disconnecting the AC adaptor and removing the battery. The error condition will be interrupted, and the AC power light will stop flashing. 2 Put the battery back into the computer. Do not connect the AC adaptor. Try turning the computer on again. If the computer starts normally, the AC adaptor may be defective and will need to be replaced. If the AC power light starts flashing, remove the battery, and continue with the steps below. 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 pcsupport.toshiba.com and see the Support If Something Goes Wrong If Something Goes Wrong The Windows® operating system is not working Bulletin Step-Charging the computer’s battery (click the Ask Iris® link and search for the 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. 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 182. The Windows® operating system is not working Once you are familiar with the desktop and used to t...
