Hi,

 

Welcome to the Lenovo forum community!

 

This is a well known issue, what happens is, windows "updates" drivers with generic ones, instead of the specific ones for Lenovo, so when that happens, you can get random things suddenly stop working.

 

Here are my suggestions:

 

This sounds like incompatible drivers from a Windows update to me.  

Windows updates have a way of messing with hardware drivers, as they sometimes tend to not be compatible with the hardware made by the laptop manufacturers, be it Dell, Asus, Lenovo etc etc.

 

What usually helps is denying Windows Updates from affecting hardware drivers completely. You can do this by performing the step below:

 

 

 

Disable Automatic Hardware drivers update

 

- Right click the Windows Icon, select the "Search" Function.

- Type "Control Panel" and select "Small icons" or "Large Icons" in the "View By" top right.

- Click the "System Icon"

- Navigate to "Advanced System Settings" -> "Hardware"

- Click "Device Installation Settings" and Select "No"

 

**This will prevent Windows from interfering with your hardware drivers in future updates, but keep crucial security updates rolling.

 

 

 

Press the Windows Key + X, or right click the Windows icon in the bottom left. Select Device Manager from the list.

 

 

Expand the following areas:  

 

- Audio input and output   (Realtek Audio or similar)

- Sound, video and game controllers  (Realtek Audio or similar)

- Software components (Realtek Audio Effects Component and Universal Service if listed)

- System devices (Intel Smart Sound and/or High Definition Audio Controller)

 

 

Update them by choosing from the driver lists on your computer, make sure to choose the most recent drivers you can find that is Audio related.

(Usually the top one or the one marked in blue if no dates are shown)

 

 

 

- Right Click the devices

- Select Update Driver

- Browse my computer for drivers

- Let me pick from a list of available drivers on my computer

- Select the most recent driver from the list for every device then Click Next

- Close confirmation dialog.

 

 

 

If nothing works, then try the to Undo the Windows update or use a System restore:

 

 

Rolling back to a previous Win 10 Version :

 

- Open the Windows 10 Settings Menu by clicking the gear icon in the Windows Start menu, or by pressing “Windows+I” keys.

- Click “Update & security”

- Click the “Recovery” tab on the sidebar.

- Under “Go back to the previous version of Windows 10,” click “Get started.”

- If this is not available, then there should always be a "restore point" you can choose from "System Recovery"

- Click the Windows key and type "System Recovery" and click "Recovery" in the list.  

- Select "Open System Restore" - Click "Next" and select the latest "Restore point" where the device was working.

 

**Note: Rollbacks Will only remove Apps and Programs installed after the selected Restore Point date. It will not remove word/text files or pictures etc.

 

 

 

Once the Update rollback or the System restore is finished and if everything is back to normal.  

Perform the Disabling of Automatic Hardware Driver updates again, so that future Win updates do not interfere with hardware drivers again.

 

If those steps did not work, please do the following, because this will reset everything back to a working state, and disable windows from messing with drivers:

To do a factory reset, first you will need to make a backup of your important files to an external USB storage unit, or to an online drive.

Then you need to turn off your laptop completely, by holding down the power button for 10 seconds.

To initiate the factory reset, you need to push the tiny button located (Go to pcsupport.lenovo.com search with your serial number, then select pane "Knowledgebase and Guides" Then find the user manual and locate the Novo buttons placement in the manual), You can use for example, a paperclip to press it, after  

you have pressed the button, the laptop will power on, and present a small menu, use the arrow keys to select factory reset, and press the  

enter key to select. Now follow the on screen instructions.

Disable Automatic Hardware drivers update

 

- Right click the Windows Icon, select the "Search" Function.

- Type "Control Panel" and select "Small icons" or "Large Icons" in the "View By" top right.

- Click the "System Icon"

- Navigate to "Advanced System Settings" -> "Hardware"

- Click "Device Installation Settings" and Select "No"

 

**This will prevent Windows from interfering with your hardware drivers in future updates, but keep crucial security updates rolling.

 

reboot, then start Lenovo Vantage, update drivers, reboot, update windows.
