Frequently asked questions

How do I know it's the board and not the battery?
Test on AC power first. If the laptop won't respond but the charge LED is on, the power board or flex is usually the cause.

Does this fit both 15-N and 14-N?
Yes, HP uses the same palmrest layout and power board for the 14-N and 15-N variants.

Will my fingerprint reader still work?
This board only carries the power button. The fingerprint reader is a separate part.
