Unusual problem with input devices?

I recently got a Lenovo G575 laptop and I noticed a strange feature - when you turn on the laptop, keyboard, touchpad no longer respond to anything. And this happens not immediately, but after a random time. Sometimes you can work 40 minutes without problems, sometimes the device is disabled immediately when the system boots.

I tried to err on the operating system(well, you never know). Replaced Windows 7 to Windows 10. The problem still remained.

All the wood is in order.

By the way, if the lid close and wait. when he goes to sleep and then open, then everything starts to work normally (until a certain point).

And, I forgot to say, mouse and keyboard work

Open, touch the contacts to close. Maybe where the connector moves...
