Laptop keeps shutting down after around one hour of use

Asked By 230 points N/A Posted on -

I have a 2- year old Compaq Presario that keeps shutting down after around one hour of use. Problem started a year ago and keeps on repeating. These are the things I have already done to revive my laptop:

  1. Cleaned the fan and heat sink. 
  2. Applied thermal paste to the heat sink.
  3. Reformatted the laptop.
  4. Installed updated anti-virus and made sure there are no malwares and Trojan.
  5. Brought my laptop to the service center.
  6. My laptop would be functioning well for around a week after I tried to fix it but it will start shutting down again. Is there any other way to truly fix it?

I believe you have tried the necessary troubleshooting steps needed for this sort of issue on laptops. The thing that would make your issue sound like a hardware problem is that it did not give you a blue screen,
Try these steps: 
  1. Shut down your laptop.
  2. Take out the battery.
  3. Plug laptop to a good power source.
  4. Use laptop for 2-3 hours, or until you experience the issue again.
If this step would resolve the issue then its a battery problem or you can try borrowing or replacing the laptop battery and check if it shuts down. If it shuts down, then try the 1st steps i gave you.
Have a good day.

Most reason for automatically shutting down is having a problem in your memory RAM. Remove the memory RAM and clean it before you insert it. If you have dual or more memory RAM, do it individually. Don't insert them together. Check them one by one just to make sure if one them have a problem. If some of it doesn't work remove it and replace. By cleaning your memory RAM.

Follow these steps: 
  1. Remove your memory RAM on your laptop then clean it using eraser.
  2. Rub the golden surface only and when your done with that.
  3. Get a soft cloth to clean the particles of eraser.
  4. Then insert it now to your computer.
