so this is an issue that's stuck around with me for a while now
i'll say now I mostly shut off my computer when I'm not using unless I'm installing something, which I was this time around
sometimes there's this issue with sleep/hibernation mode on my computer where it's impossible for the monitor to come back on from sleep/hibernation mode. basically, the screen is stuck black and the power button shines only yellow. however, ive mostly been able to 'fix' this by just restarting the computer with a press of the power or the reset button and then the computer works normally
today, I woke up and my monitor was doing it again after a while of not actually doing it, so I tried shaking my mouse around, pressing a few buttons, the usual. it didn't come on, as predicted, so I pressed the 'reset' button on my comp. oddly enough, the reset button didn't work so I instead used the power button. the monitor still didn't come out of sleep mode, and nothing I've tried has fixed it since, unplugging/replugging the monitor, pressing keys, etc. but pressing the buttons on the underside of the monitor does shake the monitor 'awake' for a quick moment before going immediately back to sleep
mid-post update - so I did something where I unplugged it, pressed one of the buttons on the underside, and quickly re-plugged it to see if I'm still getting stuff like notifications/status/etc and I am, and I got a familiar message, apparently there's no signal for either DVA or VGI. the monitor didn't stay on long enough for me to get to the final results since the monitor went back to sleep mode, but I'm willing to bet that's the issue. the problem is when I last had this issue, I just had to check over the plugins and make sure they were actually in and everything, but this doesn't seem to be the case
also I'm afraid I don't actually know the monitor name and everything, I just know it's hp brand
