Okay, I have received the following answer from support: According to Lenovo's Smartfind, only the Precision Pen 2 is compatible with the IdeaPad Duet 5: https://smartfind.lenovo.com/accessories/#/search?categoryL1Name=Stylus%20Pens%20%26%20Supplies&categoryL2Names&pageIndex=1&pageSize=40&query=82TQ Since the Digital Pen 2 is not mentioned, it is not meant for this computer. Here is the link to the compatible pen: Lenovo 4X81H95637

The Lenovo Precision Pen 2 (GX81J19854) is not compatible with Lenovo tablets, including the Lenovo Tab J 606L. It is specifically designed for certain Lenovo laptop models such as the IdeaPad Flex, Yoga and ThinkPad series.

Search in https://www.lenovo.com/ch/en/compatibilityproduct It needs a very precise product name... Yoga (Pro)(SLIM) 7i GenX

Try it here: https://support.lenovo.com/us/en/accessories/acc100180-notebook-pens-reference-guide But the best solution is to contact Lenovo support, who will be able to confirm the accounting 100%. +44 516 04 67

as it is a pen for the screen there is no mine to write, I think

I can't answer that. I have an Ideapad Flex and the pen works there.

I assume that it is compatible. But I'm not entirely sure. Maybe it's also version 3 of the pen

I think so. I also have a Lenovo Yoga Labtop and the pen works.

Strage, this works for me.

I'm sorry, I don't know for sure about the i8, but it worked for me, so I would say...

Good day I haven't had to change mine yet, but several websites (e.g. https://www.lenovo.com/ch/de/accessories-and-monitors/stylus-pens-and-supplies/pens/TAB-ACC-BO-Lenovo-Digital-Pen-2/p/GX81J19850) say that it needs a AAAA battery.

I personally haven't had it so far. It runs flawlessly for me.

Yep, also have an Ideapad Flex 5. Pen works fine.
