My Lenovo Ideapad Z575 model is not turning on when i press the button the LED lights on the button goes on when i press it and when i release it, it goes off. Last night i got the power light to stay on but the screen didn't go on and it wasn't making the boot up sounds and the only thing going was the fan and it was running hard. I have done the unplug the power cord, remove the battery, ram, and the hard drive for 30 mins. with no success. Then this morning i tried it like i did before except for the hard drive and ram, I press down on the power button for 30 secs and I replace the battery and the power cord with no success. Then i remove the battery and tried it again with pressing the power button 10 times in 1 sec intervals then held the power button for 30 secs and put it back together again but with no success. Can anyone help me?
