Chosen Solution
I’ve had this laptop for about 3 years, but this problem surfaced about 4 months ago. The laptop will suddenly switch off, and will make a high pitched “click” noise as soon as the screen turns black. The “click” sound as best as I can describe, sort of sounds like a fingernail flicking the power button, but more high-pitched and mechanical. I timed the intervals between each turn-off and it is about 25-30 minutes. When pressing the power button once, sometimes it will light up (along with the other lights of the laptop) and then will switch off, then will light up again and the computer will start up normally. I use windows 10. The power supply has been replaced, the battery changed, power cable changed, the inside has been cleaned, I’ve scanned for viruses, and I had even reset all settings and data on the laptop. My apologies if I missed an obvious solution, I’m not the best when it comes to technology! I stopped using it for a few months because the problem got so irritating, and the problem had stopped for a short while. The issue has returned and I would appreciate any help/suggestions. Thank you!
Applying the thermal paste has to be done carefully to ensure good contact and no air pockets. There are different qualities of thermal paste - maybe the one you used wasn’t quite as good as the original. Download and run Speedfan from almico.com/speedfan.php and see if your processor is running hot.
Remove your ram .. one by one to see if one or maybe both of them are faulty. This worked for me.
Your laptop could be switching off as a result of overheating due to failure of the fun. kindly check on your fan. if the fan is functioning, then the computer processor could be having a problem. Open it and apply thermal paste on the processor. You can find thermal paste in any computer repair shop
