Overheating Easynote 55 Laptop

Posted by admin | Filed under Computing and IT, Pick and Mix

I had to repair an easynote 55 laptop this week, I installed the usual diagnostic utilities, one of which is SpeedFan.

The chipset temperature probe was almost 85 degrees C, that kind of temperature is high enough to reduce the life of most standard pc components. So I took my trust screwdriver to the problem…

Unscrewed Backing Plate
Cleaned Dust from Components (Compressed Air or Gently with an none static generating brush).
I then removed the heatsink and heatpipe, attached by 4 spring loaded screws. (remove fan lead as well).

Note: The easy note has a combined CPU/Chipset cooler with a heatpipe that lines up to the side where a fan exhaust blows through it.

I then cleaned the heatsink and fan removing all traces of dust (which block airflow, or slow the fan down).
The original thermal compound had perished. So I scraped the CPU clean with a plastic store card (see pictures).
Then I reapplied a silver compound (see pictures).
The chipset wasn’t really in decent contact with the heatsink as the heatpad hardly had an indent from it.
I removed the old heatpad, applied silver thermal compound (artic silver of equiv).
As an additional measure, I added more curve the plate that touches the chipset, this means they are now in better contact.
Rescrewed the heatsink on. Reattached Fan Lead.
Replaced Back Cover of the Laptop and Rebooted. 20c drop in temperature, the CPU was also much cooler.
