Lenovo wants other companies to make accessories for its modular laptops.

Two years ago, Lenovo introduced a collection of modular Magic Bay accessories for its ThinkBook 16p. They attached to a magnetic pin connector at the top of the laptop’s display and added functionality like an improved 4K webcam, or LTE connectivity. The company has since expanded Magic Bay compatibility to more of its laptops and demonstrated concepts for additional accessories, but it’s now opening the system to third-party accessory makers, as spotted by VideoCardz.com.

According to an update a Lenovo product manager shared to the Chinese social media platform Weibo, Lenovo has “opened up support for third-party accessories.” There’s no mention of specific companies that have expressed interest or signed on to create Magic Bay accessories, or what kind of hardware they may release, but the move could potentially help further popularize the feature if there are more options available.

The manager also says the new ThinkBook 14 Plus and 16 Plus will support Magic Bay accessories, expanding availability beyond the company’s more premium laptop offerings.
