Very easy! Just buy the right tools.

Mijn probleem

My battery lasted about 15 minutes and was causing problems.

Mijn oplossing

Easy. Very easy. No idea why it was listed as Moderate. Just pay attention to the battery connector as they warn.

Mijn advies

Get an old mouse pad with a soft nonskid back, turn it over and place your screws on it in the shape they came out. Makes it real easy to get them back in the right place.
