To replace, you will need to remove the back cover by removing the two screws. You may need to extend the long hair trimmer to get to the second screw. Take off back cover to access inside. You can unsolder the batteries from the circuit board but for easier replacement, it is sometimes suggested that you use a modified installation technique. This is to break the tabs off of the old batteries with small needle nose pliers rather than unsoldering them from the circuit board. This allows the old batteries to be removed but leaves the tabs attached to the circuit board. You can then solder the tabs from the new batteries to the old existing tabs

If by on board battery you mean the cmos battery, then you would only need to replace it if your computer is constantly forggetting or losing the correct time and date..

If it is doing som the onboard battery is round and flat ( like a watch battery) and is usually accessed either under the keyboard, or by removing one of the plates on the bottom of the laptop..

Make sure the main battery is removed and the power cord is removed before replacing the onboard battery.
