You do not need to reboot or do anything else. Doing this automatically shifts the GPU into its new setting. Say you want to play a game you can switch to your max HD graphics settings by choosing your custom power profile. Right-click on the battery icon and choose Power Options Once you are ready, here is what to do next: 1. The benefit with modifying the default Balanced plan is you do not have to switch modes when you plug in.Īlternatively, with a custom power plan you can throw max HD graphics on even when on battery.

You could even just do this for the default Balanced power plan. If you opt for only AC power as you would expect the graphics will max out when you plug in the Surface Book or Surface Pro 4.

Enable max graphics only for AC power but leaves battery on balanced mode or vice versa.

Enable max graphics for both battery and when plugged into AC power.

There are a few ways to set this up depending on your preferences: Now we are going to edit the plan you created above to enable max performance of the Intel HD graphics. Up until now, all we have done is created a copy of the Balanced (default) power plan. This section is where the changes take place. Now you can reboot the PC with the registry changes and new power plan. Type in Regedit into the search window and answer yes to the User Account Control prompt Luckily, there is nothing that we are doing here that can be classified as 'risky'. That is not a good thing, so make sure you read through this how-to. That means while disabled, your Surface will never go into standby mode. Connected Standby – also called InstantGo – is what is most commonly known as 'Sleep'. The key thing to remember is you will want to re-enable CS after creating a new power profile. Once disabled and the OS has rebooted the settings appear under Advanced Power Settings.

The secret to getting the Intel HD 520 to hit max speeds is disabling Connected Standby (CS) in the Windows registry. Luckily, you can configure this so that the Intel HD 520 is only used in max 1000 MHz when either plugged into an AC outlet or you purposefully choose the Max Performance preset. In fact, doing this 'hack' (I use the term loosely) draws more power: 2.4W versus 4.0W when set to max performance.
