Had to clean the fan that is buried in the bottom of the laptop.
As usual the equipment is not nurse proof. After days of complaints about overheating I took the laptop apart to clean the fan.
In 2 hours, with the assistance of my new sorting tray and PRO TECH BASE TOOLKIT, I got it apart, cleaned and back together again. And it works.
For laptops, go slow and be careful. There are too many fragile parts.
