hi, i have a lenovo c 540 all in one, just yeasterday when i tried to turn it on i wouldn´t do it, the power button lits up and i can hear a kind of strange beep on one of the speakers, the screen stays black, i found the data conector to the hdd damaged by heat , i desconnected it from the mainboard and turned on the machine to see if that would make a change 6n the way it starts the machine, but keeps doing the same thing, if someone can tell me what to try I would appreciate it, thanks
