We changed the battery in the 97 lumina and now the MFG alarm system is in a mode where we cannot get the car to start


Disconnect negative battery cable. With key still turned on hook the cable back up. Try starting car. If that doesn't work turn key on for ten minutes. Than try cranking it. 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.

Hi! I'm getting the following message on my computer screen: Error Number : 306 A communication error has occurred. Make sure that the printer is plugged in, powered-on, and properly connected to your computer. Then try printing again. But everything is plugged in properly. I just printed something, then one minute later when I went to print something else, it wouldn't let me! Please help!!


Do the following:

Try a different usb cable.

Plug the cable into a different USB port.

Try disconnecting printer power cable for ten minutes.

Unplug computer power cord for ten minutes and restart.

Reinstall printer drivers.

If that all did not work, test the printer on a different computer, to find out if it is faulty or not.
