To fix the broken charger pin inside the Acer Aspire 5610Z laptop power jack, you need to replace the entire power jack. This is a relatively inexpensive part that costs about £6 as of 2011. But to replace this part you need to disassemble the laptop, de-solder the jack and resolder the new jack to the motherboard. If you are unfamiliar with disassembling a laptop and soldering the power jack, you can expect the process to take two or three hours to complete.

Disassemble the Acer Aspire 5610z by following the disassembly process for this laptop model (see Resources.) Remove all of the parts and keep them in separate containers so the reassembly process is easy.
Remove the motherboard from the bottom plastic assembly of the laptop and turn it over. Sit the jack on a folded piece of cardboard to give it some stability.
Connect the soldering iron and allow it to heat up. Locate the power jack contacts on the other side of the motherboard where the jack is attached.
Add fresh solder by touching new solder with the iron and placing it on the old solder. Applying new solder to the old will make it flow and remove easily.
Heat one of the newly soldered contacts and at the same time remove the flowing solder with a desoldering pump. Reheat the contact and apply the desoldering pump to all of the power jack contacts until you remove as much of the solder as you can.
Place your fingers around the jack and wiggle it to see if it will come free. In most cases you will need to reheat the contacts and apply the desoldering pump again to get the jack to wiggle free. The process may take two to three tries. Avoid using excessive force to remove the jack and make sure the solder is in its melted state when you wiggle it free.
Remove the flux and dirt from the motherboard terminals using a dry tooth brush dipped in rubbing alcohol.
Apply fresh solder to the three terminals on both sides of the motherboard to ensure a good connection of the new jack.
Place the new jack on a piece of thick cardboard and insert the upside down motherboard terminals on the jack pins. The cardboard allows you to make a tight connection between the motherboard and jack preventing any gaps from appearing.
Reassemble all the laptop parts and plastics. Reconnect the power cord and turn the laptop on.
