Shout out to your Vaio-p! I bought a Vaio-p waaayyy after the fact (2018?) & used it for a while. What a machine! Incredible. 1600x768 8-inch screen is the star of the show.

I replaced the battery but it still wouldn't run off it's own battery alas. I had a crazy ass lipo & dc-dc converter I'd use it with. Now a days with usb-pd I could just make a simple dc adapter cable for it, but I got rid of it. One of the only laptops I've ever actually discarded. But great machine.
