New Intel HD4400 drivers for Lenovo Yoga 2 Pro?

Intel has new drivers for the HD4400 graphics chipset that's supposed to fix a bunch of issues and that's downloadable from Intel's website. Intel's update utility identifies the drivers as compatible with Yoga 2 Pro, but when attempting to install the installer aborts itself and tells the user to acquire the drivers from the "manufacturer", i.e. Lenovo.

 

When I check on the Lenovo site, however, there are only drivers dated October 2013.

 

In graphics driver age that's ancient.

 

So when is Lenovo allowing its Yoga 2 Pro users to update their HD4400 drivers, which in Oct 2013 were rather broken?

 

I'm talking about inadequate resolution scaling for the Yoga 2 Pro's high-res screen in some games, for instance, which is a pretty big issue to left unfixed. Meanwhile the Intel Update Manager that came with the Yoga 2 Pro's software bundle cannot, as of May 2014, even connect itself to the net to check for updates for whatever reason.

Uninstall the "Intel Graphics Driver" in control panel. Once you uninstall the ones that came with the Y2P you will be able to install the new drivers.

Note, you do NOT need to check the box to remove the driver files when uninstalling the driver. That way the old driver is still around as a backup.

Worked for me. Thanks.

 

Though it's rather inexplicable why the Intel Update Manager failed to do the same.

I was messing around with the power saving features with the Intel Software.

 

Y2P (Power profile is my own doing)

-CPU @ .7Ghz

-Brightness @ one button press below 50% on the slider bar

-CPU utilization 0-1%

-Keyboard led off

-Wifi on

 

Panel Self refresh off

Extended battery life for gaming off

Display power saving off

= 5,600 mWh

 

Panel Self refresh on

Extended battery life for gaming on

Display power saving on (slider to max battery)

= 4,600 mWh

 

I didn't get any screen flicker but I only had it on those settings for 10 or 15 minutes

 

As I am typing this post with one tab in Firefox open it is running at 6,600 mWh. Windows reporting 4:22 Hr and 52% battery remaining.

 

Above measured with Performance Monitor .

wankel, are you using the latest intel 4400 drivers? And what settings do you think specifically allowed the flicker to disapear?

 

I have installed intel drivers before, but always end up going back to the old lenovo drivers because the brightness levels flicker a bit. Even with the adaptive brightness settings off.

 

Also, you seem to have all your settings geared towards extending battery life. I find that in all but the darkest rooms, I need brightness up close to the top for the screen to be usable.

Does anyone know what is gained/lost by replacing the Lenovo supplied drivers with the latest from Intel?
