    Well, things look bad. Ordered a new brick, and does the same thing. Seems the problem is on the main board, and warranty ended about 3 months ago. Now my 980M is unusuable, it's just a regular 17" laptop. Any intensive graphics app or game reverts to battery, and it is not a brick problem. I need to power off the laptop and wait two or three minutes to recover charging/AC power.

    Okay so...

    When you're plugged in, and it's charging.. you start to play a heavy loading game.

    Your Battery begins to go down... correct? If so.

    HOW MUCH..? What percentage is it dropping to?

    Is it completely dying as if it ran out of battery?

    If I understood correctly, you also said that once you play your game, your charger STOPS charging the laptop. So it's left running on only the battery. Correct?

    More details about battery behaviour please. It is natural for these notebooks to share load from the brick and the internal battery down to roughly 90%.

    It behaves as if you unplug the brick, the battery goes down normally, but AC is not more. That's why I thought it was the brick, that got overloaded and shuts down. Battery LED is off. If I leave the game and return to desktop, charging does NOT return, I have to power off system completely and wait 1-2 minutes with brick unplugged. Then I plug it again and battery LED goes orange, charging.

    Seems now almost clear to me that is a problem in the power internal circuit: something is broken and can't cope with an amperage above X

    After some tests:

    - Heavy CPU load: No problem
    - Faster Than Light (simple 2D game): No problem
    - Age of Wonders 3 (simple strategy game with 3D): Short Battery switchs, charging still holds, battery LED green, the battery icon appears but AC charging returns almost a second after.
    - Skyrim (Low settings): Does lasts for about 10-40 seconds. Then goes to battery, charging no more until I power off system. Battery drains as usual, fast but I think it is normal as the game is power hungry (maybe can last about 30 minutes)

    Can you use a GPU + CPU intensive bench for roughly 30 mins and monitor it?

    Could be something separating from heat..

    Yes, I will do a 3D Mark or something like that and check the temperature. I will post the results when ready.

    UPDATE: If I wait 2-3 minutes after the switch to battery, then I just unplug and plug the AC connector, the charging returns. No need to power off system.

    Seems it is not related to temperature, with a cold system, the behaviour happens, so it is more related to 980M power load.

    Hey I am having the same issue, but its also switching to battery when I am browsing now. I tried a new battery, I tried a new AC jack in. Nothing works.

    And if I try to open a game, the laptop shuts off.

    This is horrible

    Do you know if there is a way to undervolt the 980m? Did you already try it?

    I don't think making the 980m work below its voltage will help (it that's even possible to do). What I have done is testing if the problem is related to power intake of the 980m, and seems it is. In my case, when the graphic card go up XX watts, the system revert to battery. Today I will get a power meter to check how many watts are the threshold for battery change and AC shut off. The worst thing is my laptop was working OK before sending it to ASUS (I sent it because the screen failed, no hit or something, just lost a color and did strange things) returned with screen fixed and clean, but I did not try any game immediately, so I could not realize of the problem until was late to send it again.

    I understand, but my rig changes to battery even just by opening a new tab in chrome . But maybe its too much for the 980m

    Hi, since u got no responses i was thinking your issue seemsrelated with mine and also with :
    ufotheswe https://rog.asus.com/forum/showthrea...-when-stressed
    SuperWeapons2770 https://rog.asus.com/forum/showthrea...stops-charging


    I also changed the battery and it is still randomly charging. I tested the power brick with a multimeter and it seems fine.
