Compaq CQ60-215DX to the right was idling at a high 85+ celsius, which is overheat range. Bottom of laptop was extremely hot. Customer brought it in thinking it was virus related. Customer stated “it began running very slow for weeks ago and shutting down on it’s own, and would not start back up right away.” I felt the bottom of laptop, and installed a temperature program and ran a simple disk cleanup while the customer was still present.
Simple disk cleanup shot the temperature from 85-96 celsius. The laptop was overheating, this was the main problem, viruses were detected and removed later after the repair.
Basic Symptoms Of An Overheating Laptop:
Compaq_CQ60 Before Repair
Bottom of laptop very hot, keyboard palmrest area hot, screen lines or distortion, laptop periodically just powers off, cpu & gpu temperature of 70-80+ celsius.
Another blog article here: Temperature Monitoring Software. Install one of these temp monitoring programs, if your CPU temperature is 60-65+ constantly when the laptop is “idle”, nothing running, your laptop is running hot, fan is most likely blocked on inside. This is “idle” temp, if it running this warm when laptop is “idle”, what temperature do you think it will hit under full “load”?? VERY HOT.

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.

Heat build up in every laptop is a problem. With current laptops being built with Duo, Triple and Quad core processors they should not be called “laptops” anymore. For they are to hot for using on your laptop. Actually laptops should NOT be used on your laptop, for this blocks off the cool air intake vent on the bottom of laptop.

Serviced an HP G62 laptop recently, that was shutting down randomly and customer stated screen would distort at times.
HP G62 Exhaust Fan
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. Began a malware scan, and within 20 seconds temperature went from 82 celsius to 116 celsius.. red zone, fry temperature.
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.
