Could we get a battery replacement guide?

Hi @davidchang50432

Most guides on ifixit are created by users (like yourself) who have fixed their own devices and want to help others to fix theirs.

Here's a video that may help. I realize that it is not a battery replacement video per se, but it does show how to gain access so that the battery can be replaced.

The battery model number should be printed on the battery. Search online for the model number to find battery suppliers that suit you best.

If you decide to replace the battery, create a guide and post in on ifixit. Other users in the future will thank you for doing this. Here's the ifixit Durf te repareren: hoe maak je een handleiding? that may help.
