The Lenovo Slim Pen is not explicitly listed as compatible with the IdeaPad Flex 5. Some sources indicate that only certain models of the IdeaPad Flex 5 (Gen 7) support pens, and the Slim Pen is mainly recommended for ThinkBook, ThinkPad X1, Yoga 9 and similar models. For the IdeaPad Flex 5, the Lenovo Active Pen 2 is often mentioned as a compatible pen. Therefore, the Slim Pen is not guaranteed to be compatible with the IdeaPad Flex 5. It is recommended to check the exact model number of the IdeaPad Flex 5 and consult the Lenovo compatibility list.

No, unfortunately not. See here: https://smartfind.lenovo.com/accessorie...

The pen is compatible with devices that support WGP, MPP2.0, AES2.0 or AES1.0 protocols. For the Lenovo Yoga 7i 2-in-1 (16", Intel), you should check the exact model number as compatibility depends on the protocol used. According to the manufacturer, it works with many Lenovo devices, but for definitive confirmation, I recommend checking the Yoga 7i specifications on the Lenovo website or contacting customer service. If you are unsure, you can also ask in our Community.

I had exactly the same problem. Neither Digitec nor Lenovo has a replacement tip available. When I asked Lenovo Support in December 2024, they told me that Lenovo does not currently offer replacement tips for the pen. He advised me to report the pen under warranty. I did this at Digitec. After 10 minutes it was credited without asking. I have now ordered and received a new one. A nonsense without equal but there is no alternative. I hope this helps.

The Lenovo Slim Pen (4X81P44052) is designed to be compatible with several devices, but its compatibility with the Lenovo Tab M9 tablet is not explicitly confirmed in official sources. To determine compatibility, it is recommended to check the Lenovo Tab M9 tablet specifications and consult the compatibility information provided by Lenovo. In general, Lenovo pens are compatible with devices supporting WGP, MPP2.0, AES2.0, and AES1.0 protocols, but it's always best to check specifically for the tablet model in question. If you have any doubts, you can also check the Lenovo community forum or contact Lenovo customer support for more specific information.

According to my research, the article:10048632 should be compatible.
