Dell precision 7560 not charging when playing games in optimized or ultra performance mode

It sounds like the system is throttling due to heat -- does it work in a more balanced power plan?  These are thin and lightweight, with limitations on the cooling hardware as a result.  It's unlikely you'll be able to run in ultra performance mode for very long before you run up against the thermodynamic limits of a relatively small heatink.

Like the XPS systems on which they're based, these very likely draw power from the battery even when running on AC when they're heavily loaded -- as they would be when gaming.

It's not really thin and light, its design does make my back bend when carrying it around every day. i tried using powerplan balanced but i checked it still doesnt receive power even though i have the charger plugged in, it only doesnt receive power when i play games

It's normal behavior for systems that use Hybrid Power -- and the Precision 7560 is one of the systems that uses it.

i think power throting is cant,because i have disable power throting in gpedit.msc 

If the temperature rises too high, no matter what you've set the software to do, the system will still throttle.

Hello guys, it's been a long time since I replied to your answer, but after your answer, I checked and I found that when my computer reached 91%, all the power sources in my computer were reduced. I don't know if it was reduced to make the computer cooler or not? But after I checked the forums and I saw someone who also used a DELL model and also experienced the situation of reduced power supply, and he said that after he replaced the battery, everything was fixed. And I also tried to check the battery capacity with the hwinfo app and it showed that my battery's wear level was 41%. I don't know if it was the cause of the above situation or not. And I used afterburner to check the lines of the computer and it has a limit power line.

plus the info is that i had 91% before but most of it didnt drop power and everything everything was normal
