Problem with turning on my laptop

[Daniel_439]

My laptop started acting weird about 2 days ago where when I press the power button all it does is blink but doesn't turn on my laptop is a lenovo g570 I tried unplugging the battery and the plug then holding the power button for 30 seconds but that didn't work I've also tried checking I'd the power button was messed up and found that that it was slightly unplugged so I put it in correctly but that also didn't work so if anyone knows what the problem is please help

I found the problem it was the LCD wire it was slightly damaged and because of that it didn't allow the laptop to turn on so if u have the same problem try unplugging the wire and then clicking the power button cuz if it turns on after that then it's the LCD wire
