While the above advice is correct, I find myself having to fiddle with the cords a lot, so I would prep your environment so they're accessible. If I'm being an honest advocate of VR, then I must admit the cable/driver side of the Vive has not been particularly smooth. I often do not get a proper headset connection to SteamVR startup and have to reset the HMD power, link cable to USB, computer itself, etc. It's much better recently, but that's because I've adopted a protocol of starting with HMD power unplugged (but rest of cables in) -> turn on PC -> plug in HMD and wait for chimes -> boot SteamVR. But that's just my experience and could be unique to my system.
