BIOS PASSWORD??? HELP!!!


Try typing "Biostar" in as the password. If that doesn't work, we have another option.
The first step would be to try removing the CMOS battery (the coin shaped battery inside the computer that keeps the clock working). Disconnect the laptop from any power source (AC adapter), and remove the main laptop battery. Third, you will have to remove the bottom plate of the Toughbook. Search YouTube for a disassembly video for your model of tough book. Once you've removed the bottom plate, you should be able to see the internal components. Connected to the system board by two wires will be the CMOS battery. After disconnecting the CMOS battery (carefully!), hold down the power button on the laptop for about ten seconds, then let the computer sit for a few minutes to ensure that it is completely devoid of power. You will then need to reinstall the laptop battery (the main, brick-shaped one — not the CMOS) and boot up the laptop. If all goes according to plan, you should be able to access the BIOS and turn off or remove the bios password. Now you can reassemble your Toughbook. Power off, remove the battery, reconnect the CMOS battery, and reattach the rear plate, and you're good to go!

Turn it on and off three different times with the ten minute intervals. After that if car doesn't start than leave the key on for thirty minutes than try cranking it. This should work.

I can't get my songs onto my iPod Nano


The Ipod or the USB cable may be defective.
Try first connecting the Ipod to a different computer to test it, or using a different data cable.

If Ipod works, then do the following.

Unplug computer power cable, and if it is a laptop or a macbook also remove battery for ten minutes. This will get rid of elecrostatic charges on USB connectors.
If that does not work try reinstalling Itunes, this will synch the Ipod again with the computer.
