Product: HP ProBook x360 435 G8 Notebook PC (28M92AV)

Hello,

 

I am using a 30W power supply with the laptop and when diagnosing the issue noticed my power supply would stop working due to over current protection.  

So I had a look at the behaviour of the laptop and noticed that it was correctly using 15, 20 or 30W maximum power, depending on what the power supply was capable of, when suspended. 

But once active it would exceed the profile whenever a slight processing load occured, even logging into Windows was enough to trigger the power supply's OCP (overcurrent-protection) and make it stop providing charge to the laptop.  

I am aware that the 15, 20 or even 30W may not be enough to charge the laptop in all conditions, but overpowering a connected power supply is even worse than just not charging at all.  

Though my expected behaviour would just be that the laptop will take the maximum available power, but not more from the supply, that's how my Lenovo P14s and Yoga 9 do it, the Yoga even charges at 5V 3A, very slow, but it charges and never exceeds the power profile selected.
