Einleitung
If your computer seems consistently hot, please check the troubleshooting guide to determine if you might have a faulty fan. If find that your fan is clogged, or broken, and not working, this guide will show you how to dismantle the back panel and the other parts of the laptop in order to reach the fan. Keep in mind, this removal process is rather difficult, and should not be attempted alone if you are not comfortable with removing components from your laptop.
