I have a Lenovo V15 Thinkpad laptop. If I want to connect it to an older Samsung non-smart TV, I have to boot up my laptop, then attach the HDMI cable to my laptop and go from there. If the port is in use with the cable when I turn on the power, the laptop screen lights, but nothing more happens. I don't even get to GRUB. Is there a driver I can install, or something?
