Laptop starts disconnecting and reconnecting from charge when gaming

[Spinee]

(I didn't know if this was supposed to go in the laptop section or the help section, sorry if it's in the wrong place)

 

Laptop is an MSI GE72 6QF with no warranty. Clocks speeds have never been touched. Specs are attached as a DxDiag file. Lemme know if more info is needed.

 

A few days ago, I started having an issue where, during gaming sessions, my laptop would randomly stop and start charging. This would result in freezes and frame drops as the laptop requires to be plugged in in order to perform at its best.

Here's a list of things I've tried in order to fix the issue, all of them turning out unsuccessful:

 

• At first I chalked this up to a faulty charger, and bought a new one. Didn't fix the issue.
• Made sure drivers were up to date.
• Thought it was a faulty battery. Took it out and tried gaming when powered only via the adapters. This did not work and suggested that the battery is not the issue.
• Tried a different socket for both chargers.

I've also recently gotten two blue screens with the error code "VIDEO_DXGKRNL_FATAL_ERROR". Looked it up and it was suggested that I do an antivirus scan, found nothing with both Malwarebytes and Windows Defender.

 

The laptop in theory works completely fine otherwise, I'm just unable to game due to this issue. Is there anything else I can do to try to fix this issue either hardware or software wise?

 

Thanks

The charger or power management circuit is power limited for some reason.  When gaming you are exceeding the power cap of that circuit causing the system to start drawing current from the battery as well.  When this happens, windows displays the charge status as running on battery/disconnected.

 

Ive had several Ultrabooks and tablets that will do this when running synthetic stress tests.

 

Undervolt the GPU a bit, power draw will reduce by ~20% and possibly clear up this issue.

What I'm confused about is why this only started happening recently. I was able to game fine before, with no changes to chargers or anything. What could have, if it happened, changed the power limit since then? During gaming, I lose battery when charging, which is normal for the reason you stated, but Windows still displayed it as charging. Now, the charger just completely stops charging and starts charging in quick succession.

 

Is there any way I can check this power limit or adjust it?

It could just be that MS updated Windows to display the status differently recently.

 

No, not really.  You would need advanced component level / IC level knowledge and possibly firmware disassembly knowledge to change any kind of power limit... assuming its not in some kind of one shot memory that cant be altered.
