Lenovo 330s slows down when plugged

[funk88]

I recently bought Lenovo 330s with i5 8th gen, nVidia 1050, SSD... My laptop slows down badly when i plug in charger. Power settings are set to max performace, running win 10. It's so slow that is hard to do anything, even windows slow down. Any suggestions?

Is it much more responsive when unplugged and not charging? Normally it is the opposite.

I know it's supposed to be opposite, but it isnt..

UPDATE: Laptop slows down when charging, but if battery is full, and laptop is plugged it works fine.
