Can't adjust brightness in yoga 730 13

Already checked all settings including the ones on the lenovo app thing. Went to device manager and checked the generic pnp montior to make sure it was on it was. Updated my laptop to recent windows 10 did nothing. So please help!

Re: Can't adjust brightness in yoga 730 13

Hi HarryAugust,

 

Welcome to the Community Forums.

 

Initially you can shut down the machine, access the novo button (item5 page 10) to power back the laptop. This will give access to the BIOS set up so you can F9 to load BIOS defaults. Go to the exit tab to load defaults again and press F10 to save and exit.

 

Restart the machine and check if the brightness can be adjusted using F11 and F12.

 

If the same issue then use Lenovo Vantage to check updates for both Windows and drivers and apply.

 

Update us how things go.

 

Regards

I figured it out by looking though the Lenovo pre downloaded apps and by shuting it down all the way and leaving it alone for a while.

 

Edit and I updated all I could update too.

Re: Can't adjust brightness in yoga 730 13

I had a similar probelm following a Windows 10 update that overwrote the installed graphics drivers. I downloaded the appropriate graphics drivers from the Lenovo web site, be careful to select the one for your laptop/graphics combination (on-board or card) and reinstalled. It was fine after that. There is no need for a BIOS change, which can cause a bricked laptop.

Windows 10 is VERY intrusive and wants to overwrite whatever it can during its updates. It is probably best to do the folowing, if you are happy with your current hardware/driver configuration. 

Go to Control Panel, select System & Security, select System. On left hand side select Advanced System Settings, select Hardware tab, select Device Installation Settings and choose NO, then save changes. This will now prevent windows 10 from overwriting your drivers, whilst still being able to update. Note updates will probably run faster now, as it leaves your hardware alone and in the state that the manufacturer intended.
