Hi, I m an IT guy that has run out of ideas. I would like to ask you some questions about a (probably hardware related) problem that i have. All started suddenly , from one day to another all USB ports, camera and Bluetooth stopped working. I dont really care about the Bluetooth and the camera, the only thing i care about are the USB ports. I've checked them with a multi meter (only the pins that provide power) and the strange thing is that they do provide power. If i connect something like a USB flash drive , the led flashes (stays on , doesn't flickers) but nothing happens. I am sure that's not a drivers problem because the laptop doesn't even recognize them in UEFI nor CSM. My UEFI does not have an option to completely disable USB ports, only to change from USB 2 to 3 (no change at all). I m sure it's now a power problem, I've reset the bios even by the motherboard jumper.So the question is , what it may be? is it a motherboard malfunction ? Can it be fixed? Also , is there any possibility that for example the camera is faulty , or the camera cable , and short cutting something? (i mean if i disconnect the camera and the Bluetooth, is there any possibility that it will be fixed? ) thanks in advance.
p.s. also on the motherboard there isn't anything strange like a blown up resistor or something.
