Predator Helios 300 starting random beeping along with keyboard light and brightness fluctuations

Xakypoo

My Predator Helios 300, with full specs attached in image, began randomly beeping (systems beep, short, dull, random timing). I just updated BIOS which didn't help. It started all of a sudden (maybe after a Windows update but I can't be certain). Beeps are not consistent, and there is screen dimming as well as keyboard backlight issues where they change (on/off, bright/dim) for no reason. I ran hard drive diagnostics but no issues. Computer seems to be working ok otherwise though when gaming I'm noticing minor slow downs. Really need to solve this because the beeping is causing lots of stress. Can someone please help me get to the bottom of this?

Xakypoo your issue seem to be either the adapter is failing or the battery have you tried to perform a battery power drain and when you updated the bios did you reset it to the default settings also check your batter wear and if you suspect it would had been a windows update try to find which one was it and uninstall it last resort backup everything you need and perform a stock recovery clean install choose delete everything option to rule out any software issues check the instructions here also never update the bios if its not to solve a specific issue you might have that states in the bios notes itself

Ah I guess that makes sense. So what is the solution here? New adapter? Does Acer support this if it's faulty?

Xakypoo as i stated above check it to see if its faulty (if youre able to) if it is it would usually be replaced under warranty if you cant contact acer support directly and send it back to get checked

Update, I got a new charger and that did not solve the problem unfortunately. The weird thing is that while the beeping and power fluctuations occur regularly, when I launch a game then the issue generally stops until I close the game - so this would indicate it's some sort of software issue and not hardware? I did let the battery drain but the issue remains....

Beeping and power fluctuations should be addressed via warranty 100%
It indicates faulty wiring or a bad power brick, and since you've replaced the brick I recommend having Acer check it out as there's many different things that can cause power loss/fluctuations.

I would check if this button is being pressed:

What do you mean "check if that button is being pressed"??

The power interrupt button may not be pressed properly. Try putting a few layers of electrical tape to better press the button:

Hi there!! I had the same issue and I fixed it like this:
-Let your battery consume to 0 and charge it shut down to the top. When you turn on the computer it will be 100% and steel doing the beep sound. 
-Repeat this 4 times and then charge it with the computer turned on.
Hope this help!

Update: I replaced the battery but now the computer does not use battery power at all (if unplugged at all the computer dies) and shows 0% battery - plugged in. But when I run Acer Cares it says battery is in good health. There is something very wrong here but I'm not sure what. Meanwhile the computer actually does work, however I've read that without battery the cpu does not perform at the highest level and also I'd like to be able to unplug a bit. What do you think the issue may be?
