My better half has a tower that has 2 buttons down near the botton(clear color and on the left and right side))of it to power it up(or down in emergiencies). In the morning, she pushes the right button and 99 times out of a 100 it will go on but lately we have to once in a while press the left button to turn it on. It almost seems to be a power surge button or a circuit breaker button to get the machine going. Does this mean we are going to have problems with it? It's about 1 1/2 years old and should we be taking it in to get it checked out? Other than that, it works just great. Tks for any advice.
