Happy new year, I bought my Inspirion 7559 in September, and about 7days ago it's start to squeaking(like BIOS squeaking if find some errors) while I'm playing games(after about 30-45minut after start playing), or very rarely while laptop is not loading with heavy programs or games.
Before this happening i'm playing games for hours, and i haven't any problem things like i have now. I am using same programs, and playing same games so i can't notice by what it cause.
Updating of all knowing drivers and bios to last version did not give me any result.
And im also check each hardware part with diagnose utilities trying to find which one can cause this sound, but again, didnt find nothing.
I'm check with stress tests CPU and GPU from dell website, checked HDD for bads with HDDScan and checked RAM with windows memory diagnostic utility.
My guess:
-Is it possible some think with power supply unit in notebook ? Cause some times i see that charge level is 90-95% and it charging even if i didn't plug it off. But it also can be a battery save procedure.
- Or may be while laptop heating hdd or power supply unit suddenly off and on again.
-CPU heating up to 86-100degree Fan operating is no different from how they worked when I just bought a laptop. Visual all cooling parts and fans is clean, of-course i cant check thermal paste condition cause i can loose warranty state.
