Omen 15 Performance drop without charger

HP Recommended
HP Omen 15 en0037ax
Microsoft Windows 10 (64-bit)

The laptop performs fine when it is plugged in but it appears to underclock itself (CPU and GPU) when the charger is disconnected and it is running on the battery. It is a sharp and sudden drop in performance for the period for which it operates on battery power. After reconnecting the charger, the performance returns normal as expected. I have attached a screenshot of the windows task manager displaying a drop in performance (can be seen as the valley in the performance graph). I tried the windows 'edit power plan' feature to see if something there could help but that did not help either.unknown_crop.png

The reason the frames drop when unplugged is because the laptop was designed to preserve as much power as possible.Please try to select your power options and enable Max performance even when not plugged in. using following steps

 

   (a) Right click battery icon,

   (b) Select Power options,

   (c) Select current/active plan and select Change Advanced power settings,

   (d) Try options as shown

@Banhien

Thank you for your reply. As I had mentioned in my post, I had already tried that and saw that it defaulted to 100% in both cases for my default profile "HP Recommended". In addition, I have also tried setting settings in all other categories to 'High performance' or their equivalent in the same settings menu but none appear to solve the problem. Is it possible for you to confirm that it is an OS feature and not a hardcoded laptop feature? I have also turned off Nvidia's 'battery boost' using the GeForce Experience application but that too has made no difference.
