Sure you can get USB chargers that provide 12W, but the USB spec is completely hazy on how to determine how much power you can draw (the spec has changed many times - at first, you were only allowed 100mA without enumerating, this was loosened to 500mA, then USB chargers were i dentifiable so you can do 800mA. It's just a complex standard because now everything needs a bit of intelligence to operate.īut the primary thing is that USB sucks at 2.5W. Yes, I realize that the old cylindrical plug from my last thinkpad is too large for modern, thin laptops: but the USB A shaped power plug that was in intervening models is thin enough (even modern laptops have old-style USB jacks), and way more robust.Īnyone know why things have evolved into laptops being powered by power plugs that mechanically suck even on phones? Those are annoying, fiddly, and prone to breakage even in phones, where the tiny-ness is more useful. So I just in the past couple days got a new Thinkpad, and was somewhat surprised to see that the power jack was USB C. If the updates don't work out, Lenovo urges ThinkPad owners to reach out to Technical Support. The "critical firmware update" is only a mitigation for the hardware failure - keeping the machine going until the warranty expires." CNET adds: If your laptop is one of the models affected, Lenovo recommends to immediately update your system with new driver and firmware packages that are designed to resolve any USB-C problem. ![]() Users on Reddit suggest the situation is even worse. ![]() ![]() The problem affects enough models that class action suit may be appropriate because failures due to the defect have occurred outside the warranty window. It's already taken out many system boards. " couchslug adds: Anyone with more information on this expensive problem please post. It turns out that a firmware update issued in August 2019 corrupted the software controlling the port. As reported by Notebookcheck and later posted to a Lenovo support page, the USB-C firmware issue affects more than a dozen ThinkPad models including the ThinkPad X1 Carbon (5th Gen to 7th Gen), X1 Yoga (2nd Gen to 4th Gen), and P-series ThinkPads.
