  • Reverse engineer this guide to put the laptop back together.

  • Let the paste settle in by letting the computer run for a few consecutive hours.

  • Run a temperature monitor software to check if your application has been effective or not. After a day or two, you may want to stress-test it by running some high end application all together and monitor the temperature.
