Windows 10: Lenovo W520 (Windows 10) can't properly link to Lenovo tb-8704v

I can not get a new Lenovo Tab 4 plus to link to my laptop. When I connect the device I get the confirmation tone going on and off. Additionally, when I press the Media device (Mtp) box on the tablet, the screen redraws and the checkmark disapears with the conformation tone on the laptop going on and off. Looking at Device mamager, I get different devices showing up at different times. such as:


Ports:

Lenovo HS-USB Diagnostics (Com 6)
Lenovo HS-USB Media (Com5)

Modems
Lenovo HS-USB modem phone

Other devices:
Unknown device

USB:
Unknown USB Device (device descriptor request failed)


I've repeatedly tried to remove all of the devices, but I have the same result. Device mamager redraws 5-10 times untill it displays one of the various devices. They all display the yellow ! mark.


I'll also mention that Windows Explorer sometimes (often) denys access to my Synology NAS. Not sure if it's related.

Lenovo w520 upgraded to windows 10 does not recognize any cam


I have a Lenovo Laptop W520 which I upgraded 2 years ago from the original Windows 7 to Windows 10
No cam problems at all - ie the Lenovo cam worked with Windows 10
10 days ago the internal cam not recognize (see pic #1)
Soon after I noticed also USB external Logitec 9000 web cam also not recognized on laptop (updated drivers installed for windows 10 and this cam works on another computer )

Microsoft says now after removing and re-installing driver - that it will never work because the Lenovo drivers are only for windows 7. But it worked just fine until 10 days ago on windows 10







Microsoft says they cannot help because driver is only for windows 7 (even tho it worked for 2 years)
Lenovo says they cannot help because they are not planing any upgrade for this integrated web cam to windows 10

I tied unsuccessful restore - I tried returning to previous windows 10 build Nada

Microsoft is now suggesting I return completely to windows 7 but I will loose all of my data programs links etc etc

can I fix this myself?

Is there anything I can do to FORCE my laptop to recognize the internal cam or a logitec cam?
Perhaps a driver that is not exactly made for this computer but will force it to recognize the cam?

 

Lenovo Ready to Launch Windows 10 Devices

Lenovo today announced it will begin shipping a wide selection of products loaded with Windows 10 starting July 29. Lenovo has an extensive list of products eligible for this upgrade including popular models like the YOGA 3 Pro and YOGA 500. Lenovo customers can check here for their product's eligibility.

Lenovo has worked with Microsoft Corp. to make the process of upgrading simple, for people with qualified Lenovo PC running Windows 7 SP1 or 8.1 to upgrade to Windows 10. Starting on July 29, the updates will roll out. If a user has reserved a copy of Windows 10, he/she will be notified once the compatibility process confirms that the user will have a great experience, and Windows 10 has been downloaded on their system.





Lenovo Apps Enhance Windows 10 Experience
To give users consistent experiences across devices and operating systems, the preloads include a suite of Lenovo-written applications. The new Lenovo Companion 3.0 optimization tool keeps devices running at peak performance and can be used at any time to run a full-scale checkup and report back with specific actions to free up space and speed up the device. As a "smart" device control hub, the new Lenovo Settings lets users easily adapt and modify the way their device behaves. For example, when in tablet mode, the product will customize its display and other settings based on its orientation versus in traditional laptop mode. Alternatively, the device's usage will also alter its settings, for example when watching a movie versus reading an e-book. With SHAREit, customers can quickly transfer files between devices. For tablet users WRITEit takes the pen to a new level of functionality allowing users to write in any input field with their pen and the handwriting is converted to text.

As announced at Tech World in May, Lenovo and Microsoft have worked to integrate Cortana and REACHit, Lenovo's groundbreaking app that allows users who opt-in to search for and manage their content across multiple devices and cloud storage platforms. With REACHit, Cortana becomes even smarter and more personal, enabling users to find their content such as emails, photos and videos in ways they never thought possible. Cortana and REACHit gives users a seamless, intuitive way to search through natural language and contextual understanding.

"With Windows 10, computing gets more personal, productive and connected," said Tom Shell, senior vice president, PC Business Group, Lenovo. "Across our entire PC product line, from the office to the home, we've optimized our Lenovo devices to give customers a great computing experience while giving them enhanced search tools like Cortana with REACHit."

 

Lenovo w520 upgraded to windows 10 does not recognize any cam


To be super clear -
1 The Logitec cam worked well on the lenovo without special windows 10 drivers until 10 days ago.
2) The Logitec cam now works well on other computers
3) The logitec cam does not work now on the Lenovo - just as the integrated cam does not work now.
4) Even after updating the Logitec drivers to windows 10 - it does NOT now work on the lenovo


I would like to understand why and perhaps take advantage of the reason to perhaps find a way to force my W520 to accept a previous windows 10 build or driver that will cause it to work.
