ANV15-51 Problem with i5 13420h throttling for no reason

The problem is quite easy to detect, I simply start playing anything and after a certain amount of minutes, about 2 or 3, the CPU simply locks at 30W or less. The clocks drop to 3200 or 3000MHz and the CPU doesn't have extravagant temperatures, mostly 70 degrees, and before making the sudden drop it works at about 78-80 degrees while playing, which is a normal temperature and is fully functional. I've tried everything to solve it and nothing. I wanted to know if it could be a problem with the charger. The original is 135W and maybe it can't supply all the power needed by both the CPU and graphics, which are about 60W and 75W separately.

Together, the most I've seen they reach is 30W and 70W, so I also thought they would be limited to a combined consumption of 100W, which is stupid because it's impossible, I can't take advantage of the capacity. Please, I need help with this now. I don't know what else to do and it's very ANNOYING, I've updated the BIOS and I've done everything and nothing solves the problem.

    Note and emphasize that the performance loss is HUGE, removing the E cores helps but it still locks at 30w and after a while the performance is also reduced, is there any way to solve this forever without having to fiddle with throttlestop every so often or having to disconnect and connect the charger for it to restart and the cpu returns to its normal state

    Post a screenshot of the ThrottleStop TPL window so I can see your settings.

    Clear the Disable Controls box and check the MMIO Lock box in the TPL window. This can help with some power limit throttling problems. Turn on the ThrottleStop Log File option so you have a record of your computer's performance and any reasons for throttling. You can copy and paste the log file data to,

    Ensure your laptop is set to High Performance in Power Options to prevent unnecessary power limitations. Check PredatorSense or Acer Control Center for any settings restricting CPU or GPU performance. Observe your charger’s behavior during demanding tasks to see if it overheats or fails to provide stable power. If the problem persists, contact Acer Support, especially if your laptop is under warranty, for further diagnosis or replacement options.

    I have made my CPU work at a maximum of 50w to avoid overheating, but at a certain point in gaming it simply locks at 30w. I have seen that it is a common problem in these laptops but I do not know how to give it a definitive solution, locking the TPL in throttlestop helps and improves something, but it is quite annoying since sometimes I have to restart the pc several times. I have also realized that from yesterday to today a new mode has appeared in nitrosense called turbo. I have put it and it has not trothled the cpu but I do not know if it is because of throttlestop or because of the turbo mode.

    I restarted the laptop and the turbo mode disappeared hahaha

    Resolution

    1. Make sure that the thermal solution being used is compatible and correct for the specific CPU. ...
    2. Verify proper installation of the processor thermal solution. ...
    3. Make sure to apply the right amount of thermal interface material (TIM).
    4. Check system fan operation.
    5. Check air ventilation.

    For example on this case with e cores activated the CPU is chill, is only using 20w, I have to disconnect and connect the charger to see an improvement on cpu performance

    And as you can see here am almost Lossing a 30%

    The only way I managed to solve the problem was to disconnect and connect the charger; otherwise, it is impossible to solve it. That's why I asked if it could be a bad decision on Acer's part to provide a 135W power supply from the factory with these laptops.

    The other thing is, after I unplug and plug in the charger, the laptop starts to run at full power, and I start to lose charge.

    Anyway, I'm thinking of ordering a 180W charger and repasting the CPU to avoid the 88 degrees it reaches at full power, and see if I can fix this.
