These laptops reduce performance significantly when used as tablets.
I possess a Yoga 7 16IAH7 - Type 82UF system. It runs on an i7-12700h processor with 32GB RAM and uses Intel Arc A370M. This setup is quite powerful, not to mention it's paired with an EGPU (Razer Core X) that connects to a 4K display and peripherals, functioning essentially as a dock. If anyone in your group uses Lenovo products, you're likely familiar with Lenovo Vantage. I've enabled intelligent cooling in extreme performance mode, which permits higher CPU/GPU temperatures but increases fan speeds. When the laptop is docked, it operates smoothly—supporting multitasking, video playback, gaming, photo editing, and more.
The problem emerges when switching to tablet mode while connected to the dock. Performance drops significantly: videos render at 120p with only 20fps, input responses lag, the stylus works poorly due to delays, and audio quality suffers. To make it usable, I must close most apps and open just one note-taking app. Even then, occasional glitches persist.
What concerns me is that this behavior isn't typical. The fans remain silent, average CPU usage stays around 10% (never exceeding 15%), and the machine doesn’t overheat. This suggests an artificial adjustment rather than a genuine issue.
The question remains: Is this a bug or a feature? If it occurs in tablet mode, why? Does it happen with other Lenovo devices? If you own a similar laptop, check if yours experiences the same problem—especially if you don’t have an EGPU, connect it directly to a monitor, switch to tablet mode, and test.
I don’t agree at all—I’m familiar with all of them. But regarding your question: this shouldn’t occur. It also happens when your Yoga is running in standard laptop mode, meaning it’s not closed or in tablet format.
This doesn't occur in standard mode. I explored further and think "intel dynamic platform and thermal framework" might be the cause. Uncertain, but I need to investigate more.
It seems there wasn't a built-in way to switch the tablet mode manually in Windows. You might have tried physically changing it and then turning it off to test if that resolved the problem. This could help determine whether tablet mode is the cause. However, it's unclear if this feature remains available in the latest versions of Windows 10 or 11.
So, it turns out this is not a bug. I posed a question regarding this issue on the Lenovo community forums and apparently this is done on purpose to not go extremely hot. That's a valid reason but they throttle it heavily. Still waiting for a response to see how to change it.
Great to hear! There are several yoga sessions at the office, and many people favor them over carbon-based options—even though none of them seem to use pens or tablets. I’ll keep an eye out and update this thread as soon as I find a solution!
