In this guide I’ll explain how to remove the keyboard and replace the internal memory module on a HP Compaq nc6400 series laptop.
HP Compaq nc6400 has two memory slots. One of them can be easily accessed from the bottom but the second one is hidden under the keyboard. In order to replace the internal module you’ll have to remove the keyboard.
First of all, turn off the notebook, unplug it from the power adapter and remove the battery.
There are three screws securing the keyboard on the bottom.
You can remove these screws with a #8 torx or flathead screwdriver. Remove all three screws.
