Hier ein FAQ-Beitrag, der noch in Arbeit ist:
My battery life is underwhelming / I have high Idle power consumption / my dGPU does not turn off.Battery life and power consumption are closely interconnected. If your system consumes too much power – even in Idle – your battery life will suffer. Under the system of NVIDIA Optimus (MSHybrid), all common Windows app are run on the Intel UHD Graphics by default and the dedicated GPU (dGPU) should turn itself off when it is not needed. This removes the dGPU from the power source but it also saves power on the CPU side, because the CPU can turn off the PCI-Express x16 dGPU connection and thus achieve lower sleep states in each CPU cycle. This system can be disturbed in a number of ways, leading to higher power consumption which in turn leads to lower battey life.
1. System monitoring software keeping the dGPU awake.Some system monitoring software intentionally wakes up the dGPU. Keeping such software running in the background will inevitably lead to higher power consumption. We will keep a list of tools here which do and which do not keep the dGPU awake.

Please check if any of the programs on the right side of the table is running in the background on your machine. If they are, please remove them from Startup in the Task Manager.
Some of the programs on the left side of the table might wake up the dGPU once for a few seconds during initialization. But according to our testing, they won't keep the dGPU awake during normal operation.
If you want to see, whether or not your dGPU is awake or not, the best bet is to use the "Sensors" function in HWiNFO64 and keep an eye on the GPU Temperature of your NVIDIA GeForce card. If the temperature reads 0°C, the dGPU is sleeping. With a right click on the Temperature value, you can even set up an alarm in form of a sound file, notification popup or logfile entry if the temperature reaches a value ≥ 1.
2. If external monitor is connected, dGPU will be awake.Both HDMI and USB-C/DisplayPort/Thunderbolt are connected directly to the NVIDIA GeForce card. This dedicated connection gives the XMG FUSION 15 the power to drive very high resolutions, refresh rates and to support G-SYNC and FreeSync on external screens. The trade-off: the dGPU will always be awake as soon as an external monitor is connected. Rendering can still happen on the iGPU (Intel UHD Graphics) - but the dGPU will always be "awake" to deliver the pixels to the screen.
3. Every app is running on dGPU as soon as external monitor is connected? No.NVIDIA's Control Center has a hidden function called "NVIDIA GPU Activity" which supposedly shows which app is being rendered on the dGPU. Unfortunately, this function has been non-functional for a while. As soon as you have an external monitor connected, the notification window shows every newly launched app as if it's being rendered on the dGPU, even though it is not. This has been confirmed by our NVIDIA contacts to be a general issue that affects all MSHybrid laptops of every brand.
Until this issue is resolved, the "NVIDIA GPU Activity" window has no reasonable usage scenario in combination with an external monitor.
4. dGPU does not go back to sleep after disconnecting external screen in some situationsThere is one specific issue that has been observed across all devices and driver versions: if you launch certain apps while you have an external screen connected, the dGPU will keep running even after disconnecting the external screen – until you close that app. This happens despite the fact that you are forcing that app to run on Integrated Graphics. Even sending the laptop to Standby and waking it up again won't change that fact. The dGPU will only go back to sleep after you close that specific app that you launched on the external screen earlier.
Here is a short list of apps that are affected and not affected by this issue:
AffectedNot affectedGoogle ChromeMicrosoft WordMozilla Firefoxnotepad.exe
Workaround for the affected apps: close them and launch them again after disconnecting from the external screen.
We have filed a report with Intel and NVIDIA and we are awaiting their feedback.
5. Outdated drivers increasing power consumption?We had a report where an outdated Killer Wi-Fi suite caused high background CPU load. If you are using a Rivet Networks Killer Wi-Fi module, please download and install the latest drivers
here.
6. Outdated Windows and firmware?If you haven't already, make sure you are running the latest Windows updates and the latest BIOS. Some major Windows milestones (also called "Redstone" updated) need to be triggered manually by opening Windows Updates, then "Checking for updates". Under "Optional updates", there might be a "Feature update" which you can initiate with "Download and install now" (
