White light saying it’s changing but no screen or fans

Hi mate I’ll have to see cause it is open at the moment and when pressed still open and your a a legend for the schematics .. I’ll check tonight

@capsitup

When you said "Have noticed the power button is shorted to ground even not when pushed", I took this to mean that there was an earth on both the input and output side of the switch regardless of whether it was manually operated or not. That's why I suggested you check if it was short circuit.

Thanks jayeff .. Yes I probe the two points on the switch and get a short (like the switch is Normally closed not normally open till pressed) download the file and will have a look at that page you said .. it’s also interesting that I get voltage to the USB ports too.

@capsitup

Don't get caught because it may be that there is an earth coming from the chip or somewhere else

It pays to keep in mind that the switch is still connected to the board and there may be an earth coming from somewhere else so that it appears that there is short circuit switch contacts i.e. a short circuit through the earth - normally earth is on pin 2 and there is another earth on pin 1 & 3 coming from somewhere else when it shouldn't be there, if you get my drift ;-).

You may have to isolate the switch from the board to prove whether the problem is in the switch or not. Looking at the schematic it seems as though the switch is hard wired via the motherboard tracks directly to the I/O chip and not via a easily removable connection i.e. flex cable etc so unsoldering it may be the only option so that you can test it

Hi jayeff .. okay so your saying look else where .. it’s interesting because im getting voltage in to board and to the USB port and the LED power on button (it’s not glowing btw even though it reads 3v) I’ll add some photos for you
