Acer Predator Helios 300 P317-51-70A1 constantly disconnecting and reconnecting from adapter.

nvmvoidrays

alright, so, this just started happening today.

last night, my laptop was working perfectly fine. no problems at all. today, when i booted it up, it started constantly disconnecting from the AC adapter at around 80% battery life, disconnecting for as long as it takes to "drain" and then reconnecting. over and over and over.

i've done a google search and i tried the most common fixes (from this forum):

• i've uninstalled the battery drivers, turned off quick restart and restarted. problem persists.
• i've shut down my computer and pressed in the battery reset button for about 15 seconds. problem persists.
• i've put a few layers of electrical tape to keep the button that's located near the RAM pressed down. problem persists.

someone mentioned that my battery might be too worn out and needs replacing. i checked it on HWinfo and it's sitting just above 11% after 2 years of constant use. that seems pretty decent so far. but, the problem seems to disappear if i let the battery drain then plug it back in. it works just fine until it reaches that thresh hold again. i've used the device manager to try and search for updates to my battery drivers, but nada. it found nothing.

so, i'm just stumped where to go from here. any help would be appreciated.

system specs:

Windows 10 64-bit
i7 7700-HQ
GTX 1060 - Driver Version 461.40 (Jan 26th)

...oh, and, unrelated, how could i get my Windows 10 search bar working again? i disabled it a few months ago because it was making my laptop run hot while idle because it was using my dedicated card, but i can't seem to reenable it. i wanna see if a Windows Update fixed that issue.

It could be your AC adapter, check the side of your laptops adaptors plug if its not damaged and not making full contact and/or it needs replacing, could also be the actual AC jack cord that goes to the motherboard that needs replacing. Also follow the Acer "Battery is not charging" diagnoses and go check all this out:

We recommend trying the following troubleshooting if you are having problems with your device charging the battery. If the troubleshooting below does not allow your battery to charge, you may need battery replacement or repair service.

1. Make sure you are using the AC adapter and power cord that came with your product.
2. Make sure you are using a working wall outlet to charge your device. USB ports do not provide sufficient power for charging many devices.
3. If you are using a surge protector, temporarily bypass it to see if it is prohibiting your system from charging.
4. Attempt a if your device has a battery reset button.
5. If your battery is removable, remove it for the system for 10 seconds, then reinstall the battery.

hmm, alright. i'll try these and report back.

well, i checked the connectors in both where the cable goes in and the AC adapter itself. i'm using the same adapter i got with my laptop too. everything checks out. no bent pins, nothing. 

i did another test, kept it unplugged, and let the computer shut off naturally from draining the battery. i plugged it in and it worked perfectly fine. no disconnects, at all, until it hit the magic thresh hold and then it immediately disconnected itself the second it hit that percentage (80%). i think i remember limiting how far it could charge so it wouldn't go to 100% and keep charging, but i can't seem to find that option anymore... it's also literally never been a problem, except for today.

oh, i also wanted to mention, i undervolt my laptop to save on heat since i game a bunch, and i'm wondering if that might have any implications for this?

Go to the "taskbar" on the right side where the Battery icon is, right click on battery icon >Power Options > Change when the computer sleeps > Change advanced power settings and you should get this screen, see all your settings and/or set it back to default, that is where you probably changed your battery settings and that is why at 80% the laptop turns off.
