Nitro AN16-41: Cracking audio, can't change TDP, battery plan forced on AC

First I want to complain for Nitro sense. For the AMD 7840HS version it has fixed preset TDP limits. I can't change (lower) them using other tools like Universal x86 Tuning Utility. I am stuck with Acer's presets. Also the fan speed is not exactly custom. You can only set it on a fixed speed. The fans won't go lower than that speed even if the laptop gets cool and you can not set a fan speed curve depending on the temperature. These 2 issues are major for enthusiasts. You put liquid metal in this laptop but you lock the customization. Please fix these issues because other manufacturers already offer what i mentioned.

When I plug usb-c charger 65W in either usb-c port, the laptop forces battery profile. I am stuck with 15W TDP and the sound cracks - crackles when there is high power demand. This is a defect because when on battery there is not cracking - crackling sound. Do i need to send this for repair?

About the TDP, why lock it at 15W for usb-c charger and battery? Only balanced mode 15W tdp with no higher mode available? This is very low and the laptop underperforms. The processor is not U series and is designed to work at 35W TDP. Maybe it is a violation of specs to not allow us to go to 35W.

    This issue has come up allot with gamers which I can’t understand why you are complaining, as a laptop is never ever going to be a gaming desktop or perform like one, which you should know from the start and before you bought the Nitro AN16-41 gaming laptop. Your Nitro AN16-41 is pre-set by Acer for ultimate gaming for the specs that it has and the cooling that the enclosure can dissipate, if you are an enthusiast then you should know all this. As and if you increase the cpu voltage the laptop will get hotter and the laptop will not be able to dissipate the heat (even if you have the fans at full rpm) as there is a limit etc etc which you should know if you are an enthusiast.

    If you want a gaming system where you cam mod the bios ram and cpu then buy or build a gaming desktop where you have much more overclocking scope, as you will never ever reach the scope of those settings with a laptop, its just impossible! Also be aware that Acer protects its products for warranty claims and so that their gaming laptops perform reliably and do not come back for warranty work weekly due to users being allowed to overclock their Acer product unnecessarily damaging the laptop.

    The AN16-41 is NOT designed to be charged with a 65W USB-C GaN charger as its oem barrel plug adapter/chargers ranges from the lower Acer supplied 230W (19.5V 1.7x5.5x11 A230A033P LF) to the highest supplied 330W (A330A012P High power 5.5PHY (1.7x5.5x11) Brick 19.5V/16.92A) adapters, so you do the mathematics, as a 65W GaN adapter is 5 times less powerful than its max oem 330W charger. Also I suggest that you read this article "Why you don’t want a USB-C charger for your gaming laptop" as I don't really recommend a USB-C adapter also to charge your gaming laptop. Good luck and hope all this has helped you out.

    If you must use a USB-C then look at these GaN type adapter/charger of the ones below, as they will work with your laptop in its Rear Side USB-C ports which are not cheap:

    1. SlimQ F330: This is a GaN-based charger that offers a Max 330W Output (19.5V-20V) it features one DC port and two USB-C PD 3.0 ports, each capable of delivering up to 100W1. This charger is compact and lightweight, making it a convenient option for gamers on the go. USD $211.00
    2. King Ma 330W GaN Charger: This charger also supports up to 330W output through a single XT60 port, with additional USB-C (100W) and USB-A (60W) ports2. It’s designed to be smaller and lighter than traditional chargers, utilizing GaN technology for improved efficiency and reduced heat. USD $119.99

    About the crackling sound on usb c power, I connected a higher than 65 wattage usb c charger and the sound worked fine.

    Do we know up to how much power the laptop can get from usb c charging? Is it 20V * 65A = 1300 watts as shown in the above screenshot?

    Edit:
    I checked under the laptop. Says DC rating19.5V at 16.9A = 330 watts
