Hi I've just bought a HP DC 7900 ConvertibleTower, everything is working fine except for one little issue, when I try to boot up the pc I have allways to click the power on button twice in order to boot it up.
I'll explain better myself, I click the power button first, then it boots for a few seconds without any error beeps or red lights, just the green light on the right turns on and then it powers off, after that I click the power button again and it boots up normally, the two green lights are on, and everything seems normal.
I've been looking at the manual but I'm not capable to find any solution, it is not a big issue, but it is quite annoying.
Thanks in advance!
