Any time you disconnect the battery the computer automatically reboots,
Can you be more specific? Was your battery disconnected or did it lose it's charge? If you did not disconnect the computer, it would not need to be reconnected. If your battery was dead or disconnected, simply remove the positive battery cable for about 10 minutes and re-connect it. This should clear your code. Even if the code does not clear you should have no problems with the function of your car.
Some computers store the time with the help of a small internal battery known as the CMOS battery. The small battery will keep the clock of the computer running even if power is disconnected. If the computer are disconnected for to long however, the battery will run out and the time and date will be lost. If you are having problems with the time and date of your computer you should check that this battery is still working properly.

I will try to answer this. If you mean codes in the on board computer, it takes 100 miles of driving to make the computer readable if the battery has been disconnected for some time or the error codes have been erased from the ECU (computer).
Correct, a car will not start with a disconnected battery
No an airbag will not deploy if the battery is disconnected
I think you've asked this before...The computer has to be reset by the dealer. Sorry bout your luck buddy. Good Luck from now on!!!
You can reset the computer in your H2 Hummer by disconnecting the ground cable from the battery. Leaves the battery cable disconnected for 10 seconds, and reconnect.
If a portable computer, such as a MacBook, quits when disconnected from outlet power, it probably has a battery problem. Take it to a service provider if you can not determine if the battery is dead yourself.
You do not have to reset anything. but you should have the battery disconnected. and once you reconnect the battery it will reset your computer.
leave it alone for 15 minutes after disconnecting the battery then hook it back up DDUUHH
This is because each time the battery is disconnected, the computer in the car loses power. When the new battery is hooked up, the computer system needs to be reset to stop the lights from blinking.

On a computer controlled car, the computer needs the battery to for voltage regulation. With the battery unhooked, it may shut off. That is not an indication of an actual problem. The proper way to check the alternator is with a voltmeter.
P1684 simply means that the computer has recently lost battery power. Either the battery has been disconnected or there is a wiring issue.
To reset the computer on a 2002 Ford Taurus disconnect the negative battery cable. Leave the battery cable disconnected for five to ten minutes. Reconnect the cable and start the car. The computer should be reset.
Maybe. The engine computer is the voltage regulator, with the battery disconnected it may not be able to control the alternator output voltage correctly. This could cause it to go low or high.Maybe.
