G3 3579 Charging start\stop

Hello

My laptop have some issue with charging. when i plug in charger, she jumps on\off

This issue start from randomly situation, for example when battery capacity is 80+% charging normally work.

all diagnostics test show what all fine, all passed. for me not help not reinstall system with new one drive, not factory reset from factory drive, and i cant downgrade bios. Bios version is 1.11.0.

Charging normally work when 1. turn off laptop without AC adapter 2. connect AC adapter when display lid is close(when display is open this issue start again) 3. turn on after around 15 minutes

independent of charging mode setted. This issue start from any mode.

independent of environment, OS or BIOS (trying Ubuntu 18.04 with LifeUSB mode)

Adapter determine in bios how 130W, and this issue start in bios mode too

And work just fine without battery.

 

My config

Core i7-8750H

GTX1050Ti 4 gb

8 gb ram 128 ssd 1000 hdd

Re: G3 3579 Charging start\stop

Hi! I was having this same problem with my Dell G3. I believe this is a bug in the new NVidia video drivers. NVidia has created a system called "Battery Bost", where, it decreases the performance of your video card in some cases where it is consuming a lot of energy. For some reason, this makes the Dell G3 understand that we are disconnecting the AC cable, and connecting again. To solve your problem, just go to GeForce Experiance / Settings, and disable "Battery Bost".

Hope this helps.

Thank for answers, when battery is 100% its normal work when stay on AC Line 

I just inplug internal battery. hope is software problem.

BatteryBoost turning off not resolved my problem

but i think what problem around EC controller or PCH(react on tapping with 3 and 4 fingers on touchpad)

i tryed full reassemble my laptop, it take no effect

so, when i play without battery, CPU clocks down untill 800 mhz on few seconds, after up untill 2.2, after drops to 1,6 and again 0,8... with battery not have clocks drop(when issue with charging not appear)

some sounds inside AC adapter react on CPU clock down... this notebook need 180W as minimum.

also have acer Aspire 715-71G with core i5-7300HQ and GTX1050 with 2 gb...  bundeled AC adater is 135W

i will try to find original adapter with 180W power.
