Problem with wake up after lid lock ThinkPad L15 20U3000SPB

2021-04-22, 10:39 AM

Hello,

We've buy about ~20 pcs of Lenovo L15 - model 20U3000SPB.

 

With part of them we have a problem with waking up the system - when the lid is closed or the time has reach to make Windows sleep, we can't wake up the screen.

LCD goes black without any coursor (he is not powered off, only goes black), the power button is ligthed and nothing help but only forcing notebook by the power button down.

 

We try all of this soultions :

- installing newest drivers,

- reinstaliing system,

- changing modes in BIOS - we try all of them without change.

 

Right now we are using LidLock app but it doesn't solve the problem - the notebook is locking not sleeping with this soft.

 

Any ideas what also we can do?

We have the newest BIOS updated.
