I just started a new job with a very small company.  I was supplied with a used OptiPlex 3050 micro.  The power button needs replacement.  I find it necessary to push it 20-30 times until I am fortunate enough to get the machine to start.  The company is in no position to buy a replacement, or send it out for expensive repair.  I would like to know if this is a simple repair that I can complete myself.  I have had no luck finding any videos.  If anyone can help me an understanding of how complex this repair is and how to approach it I would be very appreciative.
