same here! I encountered this kind of problem after an hour of using my laptop(not dell) it suddenly shuts down. some cons of laptops to heat are:
-air vents and cooler fans are blocked by dusts.
-the High performance of your Laptop/ sometimes the high performance of the your laptop the more the heat it produces due to rapid use of the processors..
-healths issues. infertility..
-my advice is to buy laptop cooler/fans
-regular cleaning of vents
-be gentle to it
Thanks for your comment Lucas. Cleaning vents and the heat sink in a laptop is very easy. I think a lot of people are quite comfortable in opening up a desktop to perform maintenance but are reluctant to open up a laptop; I was. It’s actually surprisingly easy and much cheaper than taking it to a repair shop.
It can cause hardware failure and permanent damage. This article will introduce ways in which you can prevent or fix an overheating laptop and thus improve the performance and extend the lifespan of your laptop. I hope this shows how to stop your laptop from overheating.
I was at my wits end with the heat issue on my 1525….total dis-assembly and everything….no dice…
Ran into this and decided one last attempt and unscrewed the heat sink assembly…lifted….and what do ya know!?!?!?
Commpletely jammed with dust/lint/crud…..looked like a tiny blanket blocking the entire exit path for heat!! It’s pinned against the shell frame and deceptively appears to not be a point of potential accumulation….WRONG!
As info here are my before and after heat/speed specs
Before removing blanket of crud:
fan1 – 4900-5400 RPMs (ZINGING)
HD0 – 120 deg F
Temp1 – 193-200 deg F
Core 0 – 192-200 deg F
CPU – 195-210 deg F
DIMM – 193-205 deg F
GPU – 163 deg F
AFETR removing blanket of crud:
fan1 – 2950 RPMs (stable)
HD0 – 104 deg F
Temp1 – 106 deg F
Core 0 – 106 deg F
CPU – 109 deg F
DIMM – 105 deg F
GPU – 91 deg F
