I'm sorry but I don't think that's gonna help since I have either the 1.4 revision or the 1.5 revision. I can tell because I have the "Focus" video encoder. Also the country of manufacture is China.

First check the traces for corrosion. 

 

Every Xbox I have seen with power button issues and random booting/shutting down had trace issues, some where not even visible. 

 

If your trace is broken, the input for the Pic chip is floating around and chooses to boot/shutdown completely ramdom. 

 

Easiest way to check is to use the beeper on a fast multimeter, one point on the switch and just slide across the feet of the Pic chip and you should get a beep at one feet, if not then there is a trace broken. 

I didn't understand that last paragraph. What do you mean by multimeter. Also I'm an Aussie so I do use metric.

Can you post a pic of the main board?

And is it the same timing ie 2 minutes every time or dose it very.?

I am leaning to Bad power filter caps near the heat sink or bad solder joints on the power supply assembly

It could also be over heating from the fan not working but you would normally get some flashing lights

here is also a small chance the HDD is failing

So get snapping with your camera and include both sides and the power supply as well.

Those that can Hard-Mod. Those that can't Soft-Mod.

 

I will when I can. Have you seen the video yet. It was in the link that I included.

Also yes it does very, sometimes it won't even send a signal before it happens.

The electrolyte leaking clock cap damages traces on the under side of the motherboard on the front edge of the printed circuit board.  There are 4 very thin traces that carry the power, eject and front panel Red and Green LED control signals to and from the Xbox's System Management Controller (SMC) - a PIC processor on v1.0-1.5 consoles and the Xyclops chip on v1.6 models.

The damage can cause phantom power on and off operation of the console and DVD tray load/unload problem if really bad.

Remove the clock cap and clean the residue off both the top and bottom of the motherboard.  Look for damage on the bottom side of the motherboard such as shown in the following picture:

Repair the damage.  There are several ways to go about doing so.  Fix each trace by cleaning off the solder mask and solder a wire on each end to bridge over every small damaged section of the trace.  Or, find the starting and ending points for all 4 of these traces and solder a new wire to connect the front panel signal to the SMC bypassing all 4 traces.

Use 26 - 30 Average Wire Gauge (AWG) insulated wire-wrap wire.

The clock capacitor wasn't leaking nor was it bulging. I took it out because I didn't want to have to deal with it later.

Hello, so I have no idea what the possible problem is, I've removed the clock capacitor, check the power supply unit and haven't noticed any damage. The power button is useless at the point however I can use the eject button to power the console on.

I have a video of which can be viewed here: https://photos.app.goo.gl/b6KK7FcXXmsNTKc87
