Yoga 730 USB-C effecting Sleep/Power-On-Off/Screen (does not sleep nor wake-up)

2020-01-24, 13:19 PM

Yoga 730 following the connection of a USB-C device, does not allow sleep 

 

For Sleep - 

When commanded to sleep via Win10 menu / Power Button / Lid Close - The Laptop will turn screen-off, keep power led constant-ON  & will get stuck in this mode till forced power off

 

When not connecting the USB-C device & doing the same without it - The Laptop will maintain proper functionality

 

Even when USB-C device was "once connected" & is not connected any more,
but had been connected during the operation of the laptop"& than removed - will maintain the same "bad" behaviour

 

For Power Off - Will get stuck & not power off

 

Tested for BIOS/Driver Issue & it's a Driver Issue - Lenovo should make effort to solve

Win10 "AutoUpdate" to ver 1909 will create this problem on a well operating laptop (with updated BIOS)

 

Problem can not be solved by reinstallation of Lenovo drivers, Can't be solved by RollBack, 

Can't be solved/identified by Diagnostic Tools

 

The computer just get's stuck

 

Fresh Win10 ReInstallation - keeps the same problem

Fresh Basic Win10 with Lenovo Drivers = No Problem

Updated Win10 with Lenovo Drivers = Problem

Updated Win10 without Lenovo Drivers (Only Win Update) = Problem

 

BIOS was updated to V 2.04 

 

Can't connect the Laptop & Keep working with External Screen or External Hub (Laptop will get stuck)

 

USB-A side port - does not effect this functionality

Welcome to the Community.

 

It might help to know the make and model of the USB-C device that's at the center of the issue. It sounds as if 1909 has installed the wrong driver, changed the power savings mode of the driver or altered a registry key.  Wouldn't be the first time a Windows update has done  something like that.

Re:Yoga 730 USB-C effecting Sleep/Power-On-Off/Screen (does not sleep nor wake-up)

I am experiencing this same problem.  I have a YOGA 730-13IKB.

 

After some experimentation, I see my power light stays on and won't wake up if I try to go to sleep with my charger plugged in.  I have to force power off and reboot to get out of this mode.  If I unplug my charger, I can enter and leave sleep like normal (power light pulses and laptop goes to sleep, pressing any key wakes up the PC and I can resume).

 

I recently tried reinstalling Windows 10 using the recovery tool.  I have verified I have all the latest bios and chipset drivers from the Lenovo Vantage tool.  I did a full run of the Lenovo diagnostic tool, but no issues are reported.

 

Can we please get a fix from Lenovo for this issue?

 

From system information, I have the following:

OS Name Microsoft Windows 10 Pro

Version 10.0.18363 Build 18363

System Manufacturer LENOVO

System Model 81CT

System Type x64-based PC

Processor Intel(R) Core(TM) i5-8250U CPU @ 1.60GHz, 1801 Mhz, 4 Core(s), 8 Logical Processor(s)

I have the same issue. It's been going on since I bought it. 

Lenovo YOGA 730-13tKB

It goes into sleep mode and no matter what I do, it does not wake back up until I force shutdown mode. In this case I have lost all information that I was working on.
