Acer Predator G9-793 shuts down on its own

First of all, thank you for trying to help me.

My machine:
Acer Predator G9-793, core i7 7700HQ, GTX 1070

How it all started:
My laptop has 2 dynamic: front right and font left, and a sub somewhere under it.
About 4-5 months ago my laptop's right dynamic started giving its own random noisy sounds when I was playing performance-heavy games. Regardless of volume set, headset connected or being silenced. 
After I exited gaming the sound disappeared pretty quick, within 30-90 seconds on its own.
In time the sound became super loud and at times I had to plain send a laptop to sleep mode to shut it up. Sometimes it was coming back at once, sometimes it took good 7-10 minutes of free of noise play.
In time the sound started to appear even on relatively light games.

Red flags:
In time my laptop started beeping as if I am plugging in/plugging out. For quite a few months I was under impression that if I leave the power cable untouched it will not make any sounds. I believed in this assumption and even developed some weird habits to check the good connection frequently. I said assumption cause laptop kept and keeps giving those annoying beeps somewhat frequently even when I believe I was/am not making any disturbances.

Fat red flags:
I do not remember when my laptop has shut down on its own for the first time. Back then I thought I it might have unplugged and ran out of battery silently. Shut downs became more frequent in time.

Active situation development:
I decided to make a full clean. Disassembled the unit to the whole depths, no signs of any issues inside. I also hard removed the right sub since I play using headphones pretty much all the time anyway.
It did not help at all.
More than that the noise sounds of similar loudness started to come from left dynamic which has never happened before.
I reset BIOS with no luck. I reset BIOS via removing battery with no luck. I reset the laptop's battery with no luck.
Acer's tool says the battery is in Good condition (really surprising) while windows says I lost quite 30-35% without telling the cycle count. I intentionally used battery power for maybe 40 full cycles grand in the whole laptop's lifetime. Small breaks were no that rare but surely not close to half a thousand of full charges combined, but once again those beeps were/are raping my battery badly.

Situations as of today:
I can start a graphic heavier game like Death Stranding and step away. My laptop may start beeping on its own after 3-7 minutes. I am not even near it, sitting on the sofa on the other corner of the room reading reddit. It will eventually power off. Yes, being on charger.
I can start a graphic weak game like Per Aspers and my laptop's expectation to shut down within next 15 minutes is 70%
I can start seeming similar graphic weak game like Surviving Mars and my laptop's is expected to not shut down even after 30 minutes 85%. Maybe CPU instead of GPU, no clue, not a technician.

Subjective feeling (my newbie vision):
I believe there are supposedly 2 issues here, with battery and with adapter.
Charger is still a somewhat major here. Maybe the copper socket has burned the edge and is shorter now or whatever. But every that beep is when my laptop switches to battery power for a brisk moment. And a secondary is battery. Previously battery was enduring that raping but every now and then when the adapter disconnects itself for whatever reason if battery glitches at the same time then I am out of both adapter and battery and obv out of power.

Answering to frequent questions:
The charger connection to the laptop does get extreme hot from time to time. Shut downs are not really in correlation - laptop may shut down while charger isn't hot at all.
I can disconnect the hot cable, let it cool down for 10 minutes, plug it back, and laptop may shut down like 7 minutes later while cable is still cool.
Cable isn't getting that hot every time, only every now and then.
Frost Core doesn't change anything.
Beeping happens all the time, I don't need to do pretty much a thing. But shut downs happen only while gaming. In other words, I can watch youtube/movies as if nothing is wrong with my laptop.
Truly random beeps are really not that frequent at all while not in a game. Any game, I am not shaking laptop with keyboard heavy stuff like Heroes of the Storm or CS:GO, I can be doing just simple mouse + space in some Stellaris.

I am open to provide any information or perform any weird action with laptop.
I haven't created a ticket with Acet yet assuming they will send me to community first anyway for a quicker no-shipping resolution attempt.

    I'll start with this 'mis-impression' since your post is pretty long and this stands out. Under heavy gaming loads this is not the case if the Windows charger sound alert is turned on. This is because the charger sometimes needs help from the battery in meeting high power CPU/GPU demands. During those times, the battery is actually discharging --- that is supplying power to help the charger meet the power demand --- even though charger is plugged in. This high power demand can be intermittent during gaming. Accordingly, the Windows charger sound alert will constantly beep as if being repeatedly plugged in/unplugged even though you're not touching the charger plugs. Turn the Windows charger sound alert off to eliminate the beeps.

    Thank you for the tip! At least that is not a part of the issue it seems

    olleto your Predator G9-793 needs its mobo power/charging sections and charger looked at and diagnosed (get a new charger for a quick check) as its best if you get this laptop to be diagnosed by an experienced tech, in your area. Just as a guide, see these guys how they do it, go to their youtube channels, first go here at Electronics repair school and search how Sarin who runs this channel fixes your symptoms or go to Alex who owns NorthridgeFix that you can also send your laptop to but, he’s in the California US in as both of these expert technicians are masters of diagnosing and fixing problems like yours! As and remember, that in Acer Tech Support case (and that is why their costs are so high) as they will replace either the mobo, battery or charger or all as there must be hardware problems with the problems that you are having. Good luck and hope this helps you out.

    OK. Do these two comments capture the essence of your problem?

    No, do they? I can cut the wires from both of them, I won't cry over their absence

    thank you for your response.

    After reading multiple of other people's reports/posts I started suspecting CPU. I installed Core Temp 1.17.1 and while playing Surviving Mars (a relatively light game) in a several hours run I see Core 0 and Core 2 has exclamation signs (reaching 98 and 96 degrees C respectively). Frost Core did help with such elevations, and I bet with extra heat from graphic heavy games nothing is enough and the whole system is slowly burning out.

    Way too hot. Might have affect on speaker issue.  You've probably had this thing for at least 4 years. What do you mean by full clean? When was the last time the heatsinks were re-pasted to the processors and the heat transfer tubes were checked for obstructions?

    Account is lagging, apologize for getting back slow.

    I haven't re-pasted anything inside laptop ever. Is that meant as a routine maintenance? I thought of that as of a repair effort.
    I would greatly appreciate pointing me to some guide or suggesting a correct google query.

    Thank you!

    Absolutely routine maintenance that should be done yearly if y0u're a heavy gamer. Google search keywords 'g9-793 thermal module disassembly' for videos on how to do this. Use a quality thermal paste like Kryonaut or AcrticMX4. if you're uncomfortable doing it yourself, a local laptop repair shop should be able to do it for you. Should be about 2hrs labor charge to give you an estimate of costs based on local labor rates.
