Exact same problem, exact same solution (actually, I just removed the capacitor). Unit is 100% working now, except there is no "battery" backup meaning I have to set the system clock everytime it is unplugged for even an instant. This is because the capacitor which leaked was the one for system backup.

Did you clean off all of the acid from the leakage? Use "Lectra Motive" (sold at auto parts stores) and a toothbrush. Make sure the trace which is under that cap is still conducting to the bottom side of the motherboard (v 1.0 xbox). Check the neighboring capacitors for "bubbled tops". I had one and pulled it (tested fine though) and replaced since I had a stock of 100uf 25v caps.

I thought it was just me.

Same as first thread above.

My xbox tray started opening and closing on its own, then one day the thing just turned on by itself with the tray out. now the only way to turn it off is by unplugging it, and the only way to close the tray is to pu**** (the buttons don't work).

I'll try opening and exploring!

Do you know EXACTLY what cap. has gone bad? None of mine have signs of being bad and I have the same problem to the point where I'm lucky to get to play at all! I really appreciate it.

Slip, I'm with you. None of my caps are showing any evidence of failure, but she's dead in the water nonetheless. Any help anybody can provide would be, well... helpful... I guess the unit may be so old at this point that replacement is the best option...

I have the same problem I think as you take the MOBO and put it in the freezer for 20 minutes and see if it will boot up. I am trying to find out which capacitor is bad, I know the Aerogel is bad but that would not cause this. another site suggested that the capacitor bank that supplys the power is bad and needs to be replaced cost about twenty bucks? I don't know when I find the bank I will replace it and see I have a 1.0 and it will only boot if it is cold and it will only stay on for a short period of time then crash. lets all work on this I know we can figure it out . Thanks Jack

My Xbox started turning on by itself, It's also opening and closing the dvd drive by itself. It was very creepy.

Just wanted to add that my capacitor has also gone bad. It was one in the far corner away from the cooling fan. Front right corner. About 1/2" tall and a 1/4 " thick. It was the only one with no rating. It only shows "power store 2.5v. Series B" and also has a "2049" on it.

Haven't tried the Xbox yet. Fingers crossed. Hope this helps you too.

You can get the 1 farad caps at mouser. Part no. 504-B0810-2R5105-R They cost $2.33 each.

I've been having the same problem for a while. Power switch has become virtually useless. I can power on and off with the eject button. The system powers on by itself at random times, and only runs for a short period of time before shutting down. I checked continuity and operation of the power switch and it's OK. The problem seems to be temperature dependent, when the system warms up, it's run-time gets shorter.

My aero-gel cap also blew out. (Replacement part at Mouser.com Part no. 504-B0810-2R5105-R) It covered the board area around it with electrolyte. I removed the old cap and cleaned up the electrolyte as best as I could, but there is still a small trace left on the board. I didn't have a replacement cap so I just left it out until I get one. When I powered up the unit, everything worked fine. Power button worked great. Then about a week later everything went bad again. The power button stopped working and the system will not run for longer than 30 seconds.

The aero-gel cap provides backup power for the realtime clock. (Keeps the correct time for a few hours when you unplug the system.) I'm guessing that it has nothing to do with the power button, but something in the area must have been affected by the cleaning of the electrolyte to make it work again.

I know this isn't a solution, but it may steer someone in the right direction to get this problem solved. When I find the time, I want to pull the box apart for a better cleaning and check the components around the supercap.
