First off I have a Xbox 360 Slim, the Star Wars R2D2 edition. Everything on the xbox worked fine and dandy a couple months ago and never had any issues but I went on vacation and didn't use it or have it plugged in for 2 months. Now when I try to turn it on it only stays on for a min-few mins before shutting off by itself.
A little more about the problem. Since my xbox is the R2D2 edition when you turn it on with your finger (over the sensor) it makes an R2D2 noise. The same when you turn it off, there is a little R2D2 chirp. When you turn it on/off with the controller it does not make a noise. Anyway when my xbox 360 turns off by itself it makes the R2D2 chirp, which makes me think there is something wrong with the sensor since no one is touching it.
What I have done so far is read around on the internet and various forums and my 360 still shuts off by itself. The 1st thing I did was to clean the whole unit since it sat for 2 months I thought maybe it was just dirty. I also wiped the sensor with a cleaning towel used to clean glasses. I have also tried using a little rubbing alcohol and a computer duster and it still shuts off. The time that the xbox stays on varies though, sometimes it shuts off after a min and other times it will stay on for 5-8 mins before shutting off.
This 360 has not been abused in any way. Not that it matters but I am 35 years old and take good care of the 360. It sits in a well ventilated area and in all honesty rarely gets played or used. Everything seems to be working properly on the 360 except that it shuts off for no reason. I do not think it has anything to do with the power supply either because it always has an orange or green light on the brick.
I'm hoping this is an easy fix because I would really like to get back to using my 360. Any advice or suggestions are greatly appreciated.
