Hi @wzjuziua ,
First create a [https://www.groovypost.com/howto/generate-battery-report-windows-10/|Win 10 battery report] to check the condition of the battery to see if it really does need replacing or if there is another problem
I couldn’t find a teardown for your exact model, but here’s a link to a [https://www.youtube.com/watch?v=BoW1Uh-smpw|video] that shows a RAM upgrade for an Asus TP412 which may be of some help in gaining access to the battery. (Although to me it is wrong in that the battery was not disconnected before touching anything inside the laptop, but that’s beside the point)
The battery part number for an Asus TP410UA is 0B200-02660000.
If you search online using the part number ''only'' in the search term of your browser, you will get results for suppliers of the part
