Q: How do I install this battery?
A: Installation requires removing the bottom cover of the laptop using a Philips screwdriver. You must carefully disconnect the internal battery header from the motherboard before unscrewing the old unit. It is recommended to disable the "Built-in Battery" in the BIOS first.
