On my EU wishlist is a law mandating standard form-factors for laptop batteries (and chargers). All batteries must be user-replaceable without tools and interchangeable with those from other manufacturers. There can be 4 to 5 different form-factors to address the various sizes and power-profiles of laptops. Batteries must have standard voltages and amperages but OEMs can differentiate themselves on other factors like mAh capacity, longevity, etc. Kind of like AA, AAA batteries but appropriate for laptops. Any laptop that doesn't conform to the standards should be hit with a 50-euro enemy-of-the-planet/douchehat tax (rather than an outright ban). The industry is already there since most laptops are designed by ODMs like Clevo and Compal. The last 20 years has provided little evidence of innovation happening on batteries and chargers in the budget segment. All the custom chargers and battery sizes are designed purely to force incompatibility on customers- for planned obsolescence, to reduce competition and charge more for after-sales support. Such a law would stop this practice by OEMs of engineering planned obsolescence into their bottom-tier cookie-cutter clevo-crap but still allow companies like Apple to "innovate" on vanity metrics like slimness. An industry consortium or committee (like W3 for the web or the 4G/5G committees) can be setup to propose new revisions to the standards (if required) once every 10 years (not lesser).
