My 2017 Razer Blade Pro keeps u charging and recharging when I play certain games.

so, whenever I play a certain game on my computer and it is charging, (which it always is) sometimes it will stop charging while I have it plugged in, resulting in the dimming of the screen, and frame drops, then go back to charging and probably do it all over again. this makes most games that I play unplayable due to the extreme frame drops. I'm not entirely sure if it's the charger, battery, or charging port itself. some help on this topic would be really nice, thank you! I'm very confused as to how this works or happens, and want to get it resolved.

 

I have the same problem with my Blade 15. I have already checked a power adapter with multimeter and delivers 19-20V as it should be. So there is no problem with adapter.
UPD.
I think I made a wrong assumption and the problem related to capacitors or a plug.

 

I have the same problem with my Blade 15 mercury. The screen keeps dimming and the power keeps switching between charging and battery. Please some help topic. Thankyou.

 

Hey. I have checked it with multimeter and everything was normal , all values were same as on label. But when it is plugged in , eg under load. It “switches”. I think the problem related to capacitors or connector.And also it is extremely hard to disassemble it(be careful and follow safety rules) I have find a temporary solution that worked for me. Just try to push an adapters connector up or down. While using laptop I put something under the connector(plug) so there is a gap between the left side of the laptop and a table.
