Surface Pro 2 - Surface cover telemetry driver / blank screen after putting tablet to sleep

Hi, 

I just picked up my Surface Pro 2 256GB today and it ran into problems right after applying the firmware update that seemed to have been released just today on Windows Update.  I confirmed this problem was caused by the firmware update because I restored the tablet and the wireless was working fine and I applied the firmware update and that broke the wireless.

After the update, the Marvell AVASTAR Wireless Composite Device stopped working...meaning, the tablet does not recognize the wireless card.  This is confirmed by going into the Device Manager and seeing 2 unknown devices (one of them was the wireless card, the other unrecognized device I will explain in the next paragraph) When I tried running the update driver function, it tried to reinstall the driver but returned the following error.

Windows encountered a problem installing the driver software for your device

Reinstall the drivers for this device (Code 18)

I had to go the manual route and there were 2 Marvell drivers listed and one Microsoft driver listed for the Marvell card.  The 2 marvell drivers listed had exactly the same name.  However, only choosing and applying the second one worked.  So, the wireless was working again.

The other "unknown device" turned out to be something called "Surface Cover Telemetry".  However, trying the same troubleshooting process for the wireless card did not solve the problem and the devices still remains "unknown" in the device manager.  I just left it and carried on with installing my other software and apps as the tablet and the Type Cover 2 seemed to be functioning properly.

However, when I put the tablet to sleep by closing the Type Cover (while on battery power but charged up to 100%), the screen remained blank even though I opened up the cover again and tried to wake the tablet.  I knew that the tablet was still on but the screen remained blank even after I tried touching it, typing on the keyboard as well as briefly tapping the on/off button.  When I touch the Windows icon on the bottom frame of the tablet, I can feel a slight vibration and that told me that the tablet was on but the screen somehow is totally off.

I decided to do a soft reset of the tablet by holding on the on/off button for more then 10 seconds.  However, the screen only worked properly after many attempts.

My questions are, could it be that this "unknown device" that needs the "Surface Cover Telemetry" driver is causing this blank screen problem?  And if so, where can I download a driver that works?

Thanks.

    Hey guys/gals I got WiFi working by doing the following:

    • Search C:\ for mwlu97w8x64.inf

    I ended up using the following path which is dated 8/15/13:

    C:\Windows\WinSxS\amd64_mwlu97w8x64.inf_31bf3856ad364e35_6.3.9600.16384_none_3bc4e8962996b5bb

    • Right click mwlu97w8x64.inf and select Install.

    After you click install it should recognize the WiFi adapter and start working again. I tried doing the same with the Surface Cover Telemetry but no such luck. The problem seems to be the new driver since the old driver date 8/15/13 works fine.

    I just refreshed my 256 GB SP2 because it couldn't install kbxxxx795 the update rollup, and got stung with telemetry driver and wi-fi, not sure what I did to get WiFi working again. Going to try another refresh and the powershell script before installing updates now.

    Here's the link to the driver : http://bit.ly/1nkb1HW

    The only place I could find it was in C:\windows\system32\driverstore on a tablet that hadn't been reset.

    The latest driver packs from Microsoft didn't appear to have it in. The recovery partition on the Surface Pro 2 didn't have the driver in, either (I'm assuming else it would have been installed when I reset the tablet).

    I posted about it on my blog with some links to other fixes/a method to inject the driver into the recovery partition:http://bit.ly/1fdQRv3

    I checked it todqy. I still have the problem with the cover telemetry driver although I have the latest firmware installed. 

    And I still cannot install the driver manually.

    Are there any updates what I can do?

    so, here's what i've learned from support by phone. After replacing my defective s2p, i still had the SAME issues occuring, which is very unlikely possible since its a new hardware. 

    Here's the catch:

    Every parameters you've set in your surface tablet is stored in your SKYDRIVE ACCOUNT, it doesn't matter if your reset your tablet, some problems (those who had the first botched firmware  patch mostly) will remains as soon as you login ! Support hinted that out to me because its was not logical that my touch cover worked fine when i login and not with the UI. even the windows logo on the glass border wasn't working anymore for some very strange. reason (i didn't even know you could modify this parameter as well), to be sure, i had another account created on the device, and everything was working perfectly...

    Here's the trick : go to skydrive.live.com (preferably from another computer, while your surface is off), click on the gear, go to options, and the the last choice on your left nav bar : device parameters.

    DELETE EVERYTHING profile related to your tablet (can be a couple or more)

    now light up  your surface, login et voilà, it's all set back to default !

    but make sure to do a refresh of Your Tablet beforehand, just in case.
