Query: major power problem!!

This machine is great and convenient when it is ON. Mine had a power problem from the time I got it. I thought I could fix it with some firmware updates and stuff, but I couldn't. When I found out from online that it wasn't just me having this issue, I decided to return it. Other than power problem, I really loved it. If I find a machine that works the same as this and doesn't have any power problem, I would definitely buy it.
