Hi I just purchase a Lenovo z500 last couple of weeks. So far I have no issues about it until I discovered that the button for turning on the display(F9) take a couple of second to respond to turn it on. My estimate is about 10-15 seconds and it also always not responding whenever I hitting it. I have to press it more than twice just to turned it back on and last night it didn't turned on even though I press the button many more times so I have to forced to hold and long press the power button to reboot my PC . Please help me because I always want to turn off the display when I want to put my computer to standby mode to at least save some battery. I don't know what to do know. Please respond. Thank you.
P.S. Sorry for my bad english
