The type number will precede your laptop's serial number which is abbreviated as S/N. To confirm which battery you have, we advise that you check the model type numbers printed directly on the battery.
The laptop will need to be opened in order to change the battery. This is someyhing you can do yourself if you have a small phillips head screw driver. There are 7 phillips head screws that need to be removed to pop off the keyboard cover. The keyboard will come off and expose the battery. The battery has a ribbon cable that inserts into the main circuit board. This ribbon cable will be removed and the wiring harness on your new battery will plug into the motherboard in the same opening.
