I had an underpowered battery backup for my desk, and was using it for my gaming PC, two laptops, and two external monitors, and all my peripherals. (It didnt occur to me I was overrunning it, otherwise my rant here is nonsensical)<p>The monitors both had the same general issue - they would fail to find a signal every few weeks, and I'd find that waiting a few hours with them turned off would help.<p>I have pages of notes here. Another way to get them to work would be booting up the windows computer, which would seem to 'trick' the monitor into getting a signal on hdmi, and then I could switch to display port for the mac laptops to be used.<p>Anyways it's all crazy rambling notes, with copious timestamps, looking for patterns. I have an IR heat thermometer from the kitchen and my monitor vents would regularly have air over 160F coming out the tops when the monitors would not even post the vendor logo after a hard power reset.<p>I removed the battery backup and it's been months now with zero blips. So the only obvious takeaway I have is that overrunning a battery is a completely worthless endeavor.
