The back cover of Acer laptop was opened to look at the fan.The blades were full of dust, making the fan run slow. I cleaned the fan, and the vents with a soft brush fixed the back cover. The sound of the running fan was heard with more speed. My laptop stopped overheating.

While facing the overheating problem of my Acer laptop, I tried some of the following methods, and it worked for me.

  1. Position the laptop on a flat & hard surface – While I kept my laptop on my bed and worked, it heated up as the air vents were blocked. I used flat hardboard and kept my Acer on it, and the air started to flow through the vents and kept the machine cool.
  2. Use a cooling pad – Sometimes using a cooling pad also helps. I use it at times. It is nothing but a meshed-pad with a fan inside. It works on connecting to the USB port of the laptop. It indeed cooled down my computer to a much extent.
  3. Keep the fan and the vents clean – Cleaning the fan with and the vents with a vacuum cleaner helps to have good airflow. I cleaned them controlling the suction power of the cleaner to the lowest else it might cause other damages. I opened the back once or twice to clean the fan with a brush.

Acer laptop overheated and won’t turn on

As the Acer laptop overheats for a long time, it malfunctions and shuts down and after that doesn’t turn on. It happened twice for me. Once I was lucky, and the second time I had to rush to the service centre.

  • Cooling down the laptop – After it shut down due to overheating, I allowed my machine to cool down for hours. Then I plugged on the device to the ac adapter and pressed the “on” key, and the laptop started to work.
  • Changing the GPU – Another time, the cooling method did not work. I had to take my Acer to the service centre, and they told me the GPU or the Graphics Processor Unit got burnt due to overheating, and I got it replaced to give life to my laptop.


Acer laptop overheating and shutting down

This is how I fixed my Acer laptop that was overheating before shutting down.

  1. I went to the service center. I was told that the laptop shutdowns automatically to prevent itself from significant damages. It is programmed that way.
  2. I check the CPU & the Processor temperature at times using some of the best available software. If the temperature is above 80 degrees centigrade, then either the computer shuts down automatically, or I shut it down.
  3. However, dirt and dust gathered on the fan, and the vents block the radiation of the heat. Cleaning the vents and the fan and using a cooling pad solved my problem.

The Acer laptop can get hot when charging if the CPU has constant load at that time. The fan continuously runs for cooling the laptop and sometimes fails. The software that is corrupt can also overheat the computer.

  1. Taking help of the Task Manager – I saved all my work and closed all program. Then I pressed Alt + Ctrl + Del and opened the Task Manager. I selected the Processes Tab on the pop-up window. Then I clicked the CPU tab to check the load and do the needful to reduce it. It worked for me much time.
