Question about HP Compaq Motherboard
My Compaq Presario 1800 stopped powering on at all except for a rattling noise on the floppy that happens the same with power supply OR battery. After a full disassembly, I get this same rattling (that sounds very much like "motor boating" as it is commonly referred to in electronics) when I connect the motherboard with just the tiny PCB that holds the power-on button & other Compaq buttons. Does anyone now of such a problem? Basically, I would like to make sure that such a noise is indeeded abnormal in my test configuration (motherboard with just the buttons PCB plugged). I intend to try to debug the power supply (faulty capacitor) and if that fails, maybe buy a spare motherboard. Any comment is welcome.
