My PC won’t turn on and at first I thought it was the power adapter (the PC has an external power adapter) but it turns out when I was messing around today trying to diagnose the issue, I found this out; the the USB ports directly connected to motherboard give off some power, don’t know how much. My VGA to HDMI adapter which also requires you to plug in this USB cable connected to the adapter which turns a light blue if it is connected successfully and the light turned blue when plugged in.1 USB mouse’s RGB lights turn on when connected including the red “laser” light on the bottom of the mouse. (don’t know it’s real name)Another USB mouses “laser” on the bottom of the mouse turns on but not the RGB lights. I tested a phone charger which didn’t work at all. Does anybody know what my issue is? Could it be the motherboard or something and how could I test/fix this?
There could be possible damage to the battery cable/connector on the motherboard OR the battery cable, so if you can go into the device, look at those things to make sure that they aren’t obstructed or possibly destroyed. It also might be a problem with the battery not delivering enough power to the motherboard.
