Simply for the sake of interest. Google just spits out things about annual consumption of PC, notebook and a few other useless things.
How many watts of power consumption does such a (example 17.3 inch) notebook display have on average (0 to 100% brightness / LCD)?
According to Throttlestop, my CPU package with Netflix look between 2.3 and (rarely) 12.7W power consumption (i7 7700HQ). According to the Hhomework Monitor, the battery already has a wear level of 11% and thus still about 40Wh capacity. Now I have a runtime of just over an hour with Netflix (battery was never used by the previous owner, it only gets going after a few usage cycles). If I subtract ~ 8 to 12 W from the package, HDD and SSD, I'm at 16 to 24 Wh. So my display (lowest brightness level) would have to pull around 10W. Can't imagine that anyway, so I'll just ask here.
The 10W are quite plausible.
Since you don't specify a model, you can only guess.
Well MSI GV72 7RD.
Whether that brings so much now is the other question when I think of what feels like a million notebook models.
