Gateway M-1617 Series Laptop Overheating, Fix & Solution


Gateway M-1617 Overheating

Gateway M Series 1617 Overheating

To get to the fan & heatsink is easy on this laptop. Remove one panel off back, and you now have easy access to cooling fan & heatsink components on this laptop. Unlike most laptops you have to “tear down” completely.
 
 
I cleaned the fan, removed the fan housing and clean the heatsink exhaust vent from dust buildup, cleaned the CPU and applied fresh Arctic Cooling MX2 thermal compound.
 
 
After new hard drive install, and Windows 7 operating system. The Gateway still booted up operating at 75-80 celsius, and it continued to idle at that temperature for an hour. Still way to hot for idle temp! Keep in mind the fan was cleaned, AND the fan was running high speed, and loud.  Flip the laptop over and took another good look at that access panel.
 
 
 
 
The only cool air  intake sits to the far left on this panel, about 2″ away from fan. This intake was covered with mesh material acting as a filter, but also restricts air flow. What little air was pulling through this intake passed over the memory, passed over the hot video graphics chip.

Installed a temperature monitoring program on the laptop. And just booting up to desktop, “idle temperature” was 79-87 celsius, which is overheat high temperature range, especially on laptops.

I immediately stopped the scan, and shut the laptop down. Disconnected cord and battery and opened this HP G62 laptop up. Cooling Fan & Heatsink cooling grill was completely blocked off with dust build up.
