My does my laptop charge only when hibernated/turned off?

My laptop (HP 17-cn0xxx) doesnt charge if its not turned off or hibernated. It does show that it is connected but and the light on the side turns white (like when it is plugged in at 100%) and the battery percentage does neither increase or decrease. I heard they are pretty useless, but i still tried many programs like HP PC Hardware Diagnostics and none found any problem with the battery. Should i buy a new charger hoping for it to be the problem or is it over
