The only way Microsoft can back off of the power supply issue is to provide a different power supply. And I'm guessing there has to be some reason for why they're limiting things this way -- the Surface Connect port can't handle more power, the machine would overheat, or something. For whatever reason, Microsoft apparently just doesn't want the thing cranking at full throttle for extended periods of time.
There is a reason: It's called "Defective by design". I can understand the surface dock not being able to charge it under load at high performance, but if the proprietary charger can't take enough wattage it should have been redesigned. This isn't all about gaming, what about compiling, transcoding. . and all those other wonderful things A/V professionals do that stresses their hardware?
I hate to use car analogies, but you don't buy a Ferarri expecting it to only do 35 MPH because the fuel lines were undersized. Unfortunately, if people just accept the situation, MS will get away with this, and they SHOULDN'T. There should be a class action suit that forces them to address this OR AT THE VERY LEAST cover the battery under warranty due to increased charge/discharge for an extended period of time.
Don't get me wrong here: everything I do runs JUST FINE (more or less) on the balanced power profile. I don't necessarily NEED full throttle on this machine. What bothers me is that it wasn't announced pre-launch, which constitutes false advertising IMO, since it is unheard of to purchase a notebook computer with the understanding that it is unable to support itself under AC power under load. ESPECIALLY since batteries will degrade/die over time. What happens then. . does the machine just shut off under load? Do I have to pay an obscene amount of money to replace the battery in the next 1-2 years due to premature failure if I choose to get the maximum ADVERTISED PERFORMANCE out of my machine? What about resale value? What about generating more E-waste in the event of premature failure?
I realize I'm laying it on thick here, and that the odds of a lot of my arguments above aren't massive.... but the point, and the principle, remain. We were sold a machine that was advertised to a certain specification, and it cannot maintain that specification without degrading itself in the process. If this were ANY OTHER MANUFACTURER it would be called a defect in the charger [And it has been, especially on Razer notebooks when the 17" Blade Pros were suffering from defective 250w adapters].
