Cept anyone with a rfid reader can copy the fob or card information and use it. It can be done with less than 50$ worth of equipment.

You really can't use a Iron on the SMD's. (You can but It needs to have thermal controls). Also capacitors don't blow without a reason. There is a short somewhere else. Probably corrosion bridging a trace. To remove You just need to remove the soldier with wire brade. Re tin the cap you remove and put in place. Heat one side pushing the part down heat the other side. Should be pretty easy.

The logic boards come with the batteries. They are tuned for the cells they are on and can not be swapped because once they are disconnected it will disable the battery. This is why li-ion batteries lose the charge if they sit. The logic board is always active, so it will always be on discharging the battery at 10% per 20-30 day period. The reason for the logic's is a safety thing. If the cells overheat the cells can explode and hurt you. So the charge controller monitors this along with the max amount of charge cycles. Regardless of how many amps are still on the cells it will disable after the factory stated safe charge count.

Sparkfun has breakouts, connectors, development tools for ipod. http://www.sparkfun.com/categories/101

It is most likely a open solider joint on the motherboard. It is probably the memory slot

Norton ghost and internet security suite have this ability too. If you have comcast you should get norton iss for free. Goto comcast.net login, goto security.

Replace the ccfl. They are available on the internet. http://www.lcdparts.net/CCFL.aspx is one place.

yes battery. The battery logic board is bad or detected a (undervolt/overheat/charge count reached) then disabled battery.

it can but it is unlikely. The strip on a credit card is a constant repeat of the credit card information over and over and over again. You would have to run the magnetic strip over the magnet to do damage.

intel x25-m ssd is super fast.
