CPU performance dips when laptop is plugged in

[dirk_sg]

I bought this HP Pavilion 15t-200 cto with Intel Core I7-8565U 4c, Intel UHD graphics 620 and 12 gb of ram a little while ago. I use this laptop most of the times for music production, which is a high performance task for a processor. Now while my old laptop (8 years old) runs this perfectly fine with  Intel Core I7- 3612qm 4c, my new laptop has weird CPU utilization peaks for about 5 seconds while that occurs the clockspeed drops to 0.39 Ghz, but this basically only happens when the laptop is plugged in.

The laptop comes with a 45 Watt charger which seems a little low wattage to me. So I thought it could be the weak charger that can't handle the high wattage used compared to the power of the charger, but HP customer support told me this was the correct charger and they didn't help me at all. Can anyone help me? If anyone has a better option for a charger please tell me.

Above was my old problem but the old discussion was closed... now I did everything HP recommended to me but none of it worked so I tried using a better charger. I tried the 65 watt smart HP adapter which actually solves my problem with the CPU performance, but since this charger is 20 watts higher than the regular charger I was wondering if this would be bad for the laptop? Thanks

Yes, you can always use higher wattage without issues if it's required to run the Software

Some Notebooks will accept higher wattage than is provided by the original AC adapters.  If the system CAN'T handle the higher wattage, then it will only draw the amount that it can handle. 

Since the 65 W Ac Adapter solves the issue you are facing, you can use it without any concerns

Thank you
