I just received my new 7750 laptop and I have been having an issue just turning it on since day one? I tried looking up the guide to see what the protocol is for when it is fully powered down and turning it back on? Shouldn't it just be a simple press the power button? That generally doesn't work. I'll try to hold down the power button for over ten seconds. Nothing. Then I start to unplug everything including the power cable, usb, mouse etc.. I can keep clicking the power button but nothing. After messing with it for what seems like 5-10 minutes I eventually get it to finally boot?
