How to install a new charging plug inside the scanner?
The charging plug has been broken out of the scanner. I've
tried to use batteries but it didn't work. A person at radio
shack told me the circuit has been cut, which is why batteries
wouldn't work. When I took the scanner apart, I see three
points broken off the circuit board in a small white square
named J3. Any ideas?

If I am picturing this correctly I see two senerios, you have a 3 point pad and the trace is broken between each of them. Then you could try soldering a #30-36ga buss wire across each of the breaks. Use a very fine tip low watt soldering iron and 60-40 solder with very little flux. Delicate operation, use patience.
You should take the board out of the case if possible.
If your are really "good" you could "pull" a solder bead across each break.
The other picture I have is the whole connection is pulled up. Down side is you may have also broken the solder pads inside and through the board. If that is the case can't be fixed. But try re-soldering it back down to the board by pushing down at the same time heating with a soldering iron. Hopefully you won't short anything. You may get lucky and suceed.

Sometimes "intelligent" chargers will not start charging if a battery is too flat, but usually there will be at least a light showing that there's power to the charger.
You could try jumping a good battery across the one you want to charge to get things going (+ve to +ve, -ve to -ve).
If it's broken it's usually worth a look if you can get it apart. Look for a blown fuse, bad solder joint, wire broken, something burnt out etc. You might be able to fix it.
Don't plug it in while it's apart unless you are certain that nothing will short out and that you will not touch any live wires!
You state that this "was new out of box" the machine. If this is so and particularly if the machine is new then you should take it back to the vendor for him to replace with a working unit, because clearly the one you have is "not of Merchantable Quality".

It sounds like the charging port on your phone is broken. This could have happened a number of ways. Either by dropping your phone, putting the charger in wrong, or taking it out wrong. If you call HTC(866-449-8358) and it is still under warranty they will probably fix it for free as long as it doesn't have any water damage(http://www.ehow.com/how_4479971_check-cell-phone-water-damage.html). Otherwise you could also get a new phone.
honestly you've done everything correctly that i could think of. one last thing you could try to root out a problem with the os. is boot the computer from hirens boot disk and load the portable Windows. see if the battery is detected in hirens. then youll know if its a Windows problem or not.
personally i feel the board is the issue but it doesn't hurt to check the complete os.
If the battery is fully charged but still your unit does not work, the problem could be a lost contact inside your scanner. It could be a factory defect. What you've got to do is to call your service provider about it. They can definitely help you solve it. Thanks.
Is the AC Power adapter the original adapter of the laptop? If it is,
try to drain the battery and charge it for 8-12 hours without using or opening the laptop just charge it. After charging, remove the power adapter as you open your laptop. Make this way a habbit of using and charging your laptop to make the charging and battery life last long.
Does the back dc jack seem loose when you have the ac adapter plugged into it? Wiggle the cord right where it plugs into the laptop. If it moves around then most likely the dc jack on the inside has one of it's 3 points of contact broken. This means that someone would need to re-solder that contact or put a whole new jack into the laptop. Another thing to try is replacing the battery. Sometimes they won't charge because they are bad. Another thing to try is take the battery out, plug it into the adapter, turn it on, get into windows, shut down, put battery back in, turn on. See if that resets the battery and makes it charge.
The BC72XLT is a battery-operated scanner, and your power supply is a battery charger, not a battery eliminator. You must have batteries in the unit for it to operate. You can install rechargeable batteries and use it in conjunction with the power supply, or you can run it on non-chargeable alkaline batteries.
