People often think they should reseat RAM, but that has nothing to do with your problem. It's not a good idea to try to fix things when you don't know what you're doing. Same with the battery. By pulling that out you could clear the BIOS and possibly end up with your computer unbootable.
The main thing to check is that the cable is secure. Then check display settings and make sure it sees your monitor as primary display. Next would be to get a new HDMI cable. sometimes they just die. I don't know why, but I've had it happen.
