I got another TLV70733PDQN and replaced UT390. Now I got 3.3v on PP3V3_S2_IPD, but the keyboard and trackpad still did not work. The trackpad does not even click, so it seemed like its not getting power at all. I checked all the traces and they seemed fine, so I suspected the trackpad was bad. Got a new trackpad and tested it, but still had the same issue. It ended up being a faulty lid angle sensor on the screen that was causing all these issues. I replaced the lid angle sensor and everything is working fine now.
