Do yours have a pen?

Do you use a cover that can cause a standby?

My device has a pen (WWAN, NFC). I don´t have a magnetic cover, I have the normal case. But you can test this with an normal magnet, holding it on the botton mid. With the Lenovo graphic driver you can use this function to put the device on or off, with the original Intel drivers, that doesn´t work. Cause I don´t have this cover, I don´t need this function.

But I still have the problem with the graphic drivers crashing on every wakeup and two times I had the b/w screen, since I updated my RTM with the final patches.

I think the problem is the new Instant go function (in Windows 8 a similar function was called Connected Standby).

Someone maybe knows where to download version 1165 or 1168 graphic drivers? I know they are exiting and available, but didn´t find some time to search for them.

Thank you.

Yes, I have a pen and a magnetic cover, and have the display driver crashing issue.

I've also got a Bluetooth crashing issue as well. Happy days :-(

The topic is also discussed in the following threads. There is also an official response from a Lenovo employee in the first one:

uninstall following patchs could resolve this issue

I wish I could try this.  All of those updates that you've listed don't give the option to uninstall.

Hey,

Thanks profichiller!

I see there is a lot of overlap between several threads all around display driver.   I'd really like to get a handle on how many unique customers we have with these issues, what version BIOS, video driver and the symptoms that are experiencing to narrow down our testing, and perhaps find one or two people we might want to have a look at their system (best to find people in US).

Can we merge these discussions on display?

Hi, Mark

I replied on the other thread.

Admin edit:

The .1176 / .1177 drivers made available later via Windows update and subsequently on the Lenovo support site should provide improved performance and stability under Windows 8 / 8.1.  If you are experiencing display driver issues, we recommend you upgrade to .1176 or .1177.   You may also wish to considering updated to BIOS 2.1 or later with all the bundled drivers now available on the support site.  Please see this related thread

I'm leaving DCRDeveloper's post below marked as the solution as it was the best solution at the time and his contributions to the community in this area were valuable.

Mark,

The fix for the video issue is in the my post, but first some background.

I am truly amazed that after a week Lenovo doesn't have a clear picture that the 1160 drivers as part of the Windows 8.1 update are failing.  I am also surprised that the 1099 drivers are still on the web site without a warning that using them on 8.1 can brick your machine.  

For the record my system is running Win 8.1 Standard, with Office 2013 Home Student (this was the $499 deal offered over the Labor Day Weekend).  I am running the 1.31 BIOS.  Everything was humming along just fine under 8.0.  After upgrading to 8.1, I ran head long into the "cover unlock wake from sleep" issue that has hit many users. After reading about 10 hours of internet threads I was able to discern that, Lenovo was clueless as to the problem and Intel was in denial saying it was the Manufacturers issue, but the problem is clearly in their code.  Seriously, can't you guys just call each other and nail this down.  As a user this back and forth gets really, really old!

The drivers everyone is looking for are at the Dell Bermuda site.  They are the 1130 drivers.

http://www.dell.com/support/drivers/bm/en/19/driverdetails?driverid=CRT47

Here's the installation instructions.

1. download the file - these are for the Dell Latitude 10

2. The file - Intel_CLV_installer_PR7_A05_CRT47_ZPE.exe is just a self extracting zip file, so go ahead run.

3 The contents will extract to C:\dell\Drivers\CRT47

4. Once done, go in and manually update the video driver.  From Win 8.l, Open Charm Bar, Search for Control Panel.  Open System, Device Manager, Display Adapters, Intel Graphics Media Accelerator.  Next  click on the drivers tab and choose update driver.  Choose Browse My Computer, Let Me Pick...., and then make sure to click the Have Disk button.

5. You will then browse to the following location.  C:\dell\Drivers\CRT47\Drivers\Graphics or where every you unzipped the files to.

6. The system will show you two possible choices, I have tested both and found that the "igd_gfx32_clv" is the best choice.  The 50907 seems to show a black screen on wake\unlock every once and a while.  You can get around this by hitting the Windows button on the front of the tablet.

7.  Install Drivers and Reboot.

8. After Reboot run Windows update.  Windows will show you and updated video driver, it's the 1160 driver, you will want to right click (or long press) on the this update and choose hide so you will not inadvertently install this driver.

I have taken the time to post detailed instructions for the less technical among the group that are struggling with the problem, and feel that 8.1 has been more trouble than it's worth.  I hope this helps everyone.  

Now that you have your temporary fix, what's different between the 1130 drivers and the 1150+?

I'll bet that if the president of Lenovo were having this problem you'd know the answer!
