Sleep Problems and Noise

[Ccc]

Hello everyone

As discussed a lot ,sleep problem is still a unresolved problem.

I recent found something very interesting

what I found is as follows:

 

1 On my laptop I found that after I choose sleep , close the monitor, then open the monitor again ,it comes back normally. without noise. But usb devices can not work again. It does recognize it.

 

2 If I just close the monitor,it will sleep , after you open it , the screen does not come back.

But ,if you then close it again and reopen it ,it will come back normally .

 

But on my laptop it will then come with noise output problems when listening music or watch a movie and I can not use usb devices too，And Sometimes it wakes up but the track pad is unusable, makes the cursor move very fast and jerky.

 

 

My laotop is Dell inspiron 2200
