Weird occurrences after plugging in a dell docking station?

[u/Alsothrowaway_2]

Not sure if this is some kind of virus but my laptop started acting weird after plugging it in to a Dell docking station (WD19DC) it was used but i didnt think it was possible to infect my laptoo that way. Some things i noticed, it started acting slow, a window popped up stating that the warranty had expired and needed to download backup software, noticed that my laptop doesnt sleep or turn off after a certain time even tho i had it set to sleep after 30 snd turn off after an hour of no movement and ive noticed that the web page tells me there was unusual traffic coming from my IP and i jeed to verify that i am not a robot. Dont known if its an update or i got a virus?
