My new PC won't boot "headless"
Sun Jun 05, 2022 3:05am

Wow, the level of stupidity there is just insane. Why on earth can't I leave the monitor unplugged and boot the system? It's a Lenovo ThinkCentre.

There's these things called "dummy plugs" that get around this inanity but why they even exist is beyond me. Did PC manufacturers just decide that we can't use our boxes headless? Did they not realize that sometimes a server doesn't really need much power, just a few gHz CPU speed and a few gig of RAM to run OctoPrint? I'm still amazed at the stupidity. Really wow.

Boot anyway. Let the OPERATING SYSTEM take care of OPERATING the machine. The BIOS's ONE JOB is to get hardware information to the OPERATING SYSTEM so the OPERATING SYSTEM can OPERATE. Not do stupid things like refuse to boot because some unlucky person wanted to run the computer without a monitor.

Off to Amazon to get some dummy plugs.

Btw, I hate display port too. PC manufacturers like Lenovo love it, display makers OTOH, love HDMI. Let's be incompatible because we can.

    • Oof... that's an awful "feature". - Erik_, Mon Jun 13 2022 12:57pm
      What could even be the reasoning for it? Are there really that many PCs that might accidentally be turned on without someone knowing about it that they require something like that? Unless it's a cheap way to cover a bug or something. Like, if the monitor isn't present at boot, plugging one in after... more
      • Maybe it's to slow down mining efforts? - Puckdropper, Mon Jun 20 2022 12:55am
        But honestly, the miners are going to just use cards that don't have that anti-feature. (Or attach a resistor to the VGA pins for a cheap fix.) If it is to cover a bug, why not pretend you have a standard resolution monitor attached, like 1024x768? When a new monitor appears, update the system to... more
        • On the bright side, at least it was only $10! - Erik_, Thu Jun 23 2022 1:11am
          I didn't consider miners. That could be a possibility though I thought they used high end graphics cards to mine? If the code is burned into the BIOS ROM and they didn't have time to fix the bug correctly before the batches were made, it might have been the quickest dirtiest fix they could do to hide... more
          • It's the dumbest anti-feature I can think of - Puckdropper, Sat Jun 25 2022 11:54pm
            I just can't fathom why they'd do that. If it was security, have a method to ENABLE it in the BIOS. I get so tired of having to ask someone's permission to do something. "Can I use my PC as a headless low stress server?" "NO, it's a PC not a server." "Here, let me install the equivalent to piping... more
