    Computer question--What the hell is HDMI???

    My computer quit working and it was an old computer. I got a pretty decent computer from a lady off Craigslist which I am now trying to get to work.

    I am presently accessing the internet through a laptop I am borrowing. I am accessing the internet through a cable modem. However, the computer I acquired has an HDMI port. My access to the internet appears to be through the HDMI port which does not support the cable modem.

    In order to access the internet right now I have to use the power supply from the old computer and its elaborate series of cables to connect to the modem successfully. I then run the ethernet cable to the laptop from the modem

    How the hell do you get internet with an HDMI port? All I have is a basic cable that sticks into the back of the computer. The old computer had an elaborate series of power banks which support the power for the cable modem.

    I have no clue right now and can barely figure out how I have this damn laptop working.

    I assumed all computers worked the same way. I forgot how elaborate this power supply is on the old computer. I think I cannot use this computer with cable. I called the cable company and they had no clue what I was talking about.

    Hey Roger, it's possible to transmit data over HDMI, but not ideal.

    Is the computer you bought from Craigslist a desktop or laptop? Does it have an Ethernet port? Most desktops will have one. It looks like a phone jack, but larger.

    The thing is the laptop would not work either. I think most people use wireless for laptops.

    Yes, it has an ethernet port. The problem is the power supply for the modem. Desktop.

    You can take your ethernet and connect to the computer and you can connect the ethernet to the modem, But you have no way of powering the modem. A modem comes assuming you have a power source from the computer.

    Connect your modem. ... To connect it to your computer, plug one end of an Ethernet cable into the Ethernet or LAN port on the back of your modem, then plug the other end into the Ethernet port on the back of your computer. Your modem should come with an Ethernet cable, but any old Ethernet cable will do.

    Connect one end of the coaxial cable to the cable wall outlet, then connect the other end to the modem. Connect the modem power cord into an electrical outlet, then connect the other end to the modem. Note: Most modems are always on and don't have a power switch. If there is a power switch on the modem, turn it on.

    I had to get a computer guy to break into this thing because I bought it from an 80-year-old lady a few years ago. She would not even give me the power cord. She is dead now. I am going to have to call that computer guy. He has a computer repair/vape business.

    Your Ethernet should be connected just like you describe, with an Ethernet cable between your modem and your laptop Ethernet port. What you are describing as a "power supply" may be a universal docking station which allows you to connect all sorts of devices through one USB connection in your laptop. You don't need that to connect to the Internet. You just need the Ethernet cable between your modem and your laoptop.

    You don't get Internet through an HDMI cable. HDMI stands for "high-definition multimedia interface". The key is "multimedia". It's used for video and sound.

    I use an HDMI cable to connect from my laptop HDMI port to the HDMI port on my big screen TV. I am viewing SBR on my TV by selecting the HDMI port as input. It gets the signal from my laptop.

    Honestly the setup sounds super janky. You should be able to get internet through an ethernet port or over wifi at a minimum. Your power cord and HDMI shouldn't have anything to do with it. They are used for power and display.

    This is not Rocket Science. Are you saying that you have a laptop AND an old desktop computer bought on Craigslist? First things first INTERNET - if you pay for internet for example Xfinity. You will have a cable modem. That modem uses the coaxial cable from outside your house to inside to the cable modem. That modem will have an internet port or maybe a group of 4 ports. You can plug an ethernet cable into one of those ports and hook that up to your desktop. The cable modem also most likely has a wireless router that your laptop can connect to wirelessly. You need to know the name of the network and have the password, most of the time, xfinity sticks a label on the modem with the details. If you don't want to run a wire from your cable modem to your desktop, you can buy a wireless card that can connect to the desktop via USB or inside the desktop via PCI. HDMI is used to connect the desktop to a monitor or TV. HDMI does not provide internet nor power. USB C can provide both but I doubt you have a USBC port on an old desktop.

    Side note - sometimes you can pick up wifi signals from neighbors that are not password protected. You can sometimes connect to those open networks without paying for internet. A directional antenna can pick up signals from a far distance.

    OK, problem solved. The problem was that the extensive power system of the old computer system had a cord from one of the power boxes that went straight to the modem. So when I got out the modem box I found the standard power cord that I did not know existed.

    The new computer is way worse than my old computer. A total piece of junk and outdated. But will have to do for now.

    Thanks for the attempts at help.

    You can build your own computer fairly cheaply. Probably can use the old case but new cases are relatively cheap as well. Graphic cards are the tough ticket to find today. A good graphics card is going to set you back a bit.

    I think you must have figured out by now why the computer was offered on Craiglist and not at a store. Someone who didn't know what was doing built it in their garage and sold it to you. Could be a 6th grader.

    No, it was basically brand new. She did not like Windows 8. Problem now is I have no sound. Checked sound when I tested it and it worked.

    does it come with external speakers? if so, make sure they're connected to the proper audio port on your tower.

    The speakers are OK. The computer beeps. But the sound is not enabled. I can see where it is disabled but it does not give an option of enabling. The speaker icon also has a red x on it.

    It is literally straight out of the box at Best Buy. I've got the box and the wrapping and everything. It was used for maybe a month. Had the warranty at the time.
