This well-written guide applies for HP Pavilion Gaming 15-dk0000 models as the laptop opens pretty much the same way, BUT the correct battery for the model is the PG03XL - HP Spectre x360 15-ap Laptop Battery - PG03XL, just a heads up. Thank you for writing it!

Fixed my old Kindle Keyboard with this guide and a replacement battery I bought off of this site. Did exactly what was outlined, no unexpected things, easy five minute replacement, device loaded like a charm. Perfect beginner guide, thanks!

As a note, my old battery is swollen and is already in a battery center's disposal bin.
