Motherboard exposed after some serious screwdriver work. Fan and heatshink have already been removed.

Some weeks ago, a Hewlett-Packard Pavilion tx2500 series convertible notebook assigned for retirement came to my hands with a flickering video problem. After digging the Internet for a while, I found this PC suffers a commonly known CPU/GPU overheating problem because poorly applied thermal solutions.

Poorly applied thermal paste over the AMD Turion X2 CPU.

This thermal pad will be replaced by a copper shim.

This notebook can be easily fixed using a cheap copper shim and good thermal paste. There is a rather large (1mm.~) gap between GPU and heatsink filled from factory with an adhesive thermal pad. This pad diminish over time and GPU overheats very quickly. Replacing it with a copper shim solves the problem.

The copper shim is attached to the GPU using silicone based themal glue.

Thermal paste applied between the heatsink and the copper shim.

After spending some precious time putting all back together, the Pavilion tx2500 is on the road again running Windows 8 Release Preview without any hiccups.
