Look for "slim tip to usb c adapter" On Fri, Jul 3, 2026 at 5:00 PM William Park via Talk <talk@lists.gtalug.org> wrote:
My laptop, T450, has 2 batteries, one of which is dead. Instead of getting a new battery, I chose a cheaper solution... 3 Lenovo power supplies throughout the house. So, if I get a new laptop, I have to get rid of all the old stuffs? :-(

Having finally received my warranty replacement laptop (took 3.5 months due to parts not getting delivered from intel, specifically CPUs. How I hate this stupid AI craze.) I noticed the replacement now has USB-C for the power connector rather than a proprietary lenovo plug. Given the power requirements I remember them having in the past that seemed like a low since I thought 100W was the maximum (20V at 5A), but no it turns out they support 28V, 36V and 48V these days, and this power supply supports up to 28V, so 140W. That's impressive. I guess the days of proprietary power supplies might actually be numbered.
