If you have problems with Lync and video calls, this may work:
Install the driver from Lenovo for optimus, but change the NVIDIA files with the native ones from nvidia.com.
I installed this version and it worked: 280.26-notebook-win7-winvista-64bit-international-whql
Run this on the client: nslookup -type=srv _vlmcs._tcp
Setting Keyboard Local in Winpe for MDT 2010 you can add this line to bootstrap.ini:
KeyboardLocalePE=0414:00000414
Have you tried to find a program to make a video guide, and did’nt find anything?
Then you can try this free program from Microsoft: Screenrecorder

This maybe the same problem for other Intel software installation, but if you are installing Intel HD Graphics silent in a task sequence, then it won’t install and you get this errer code: ” Error Code 14″ !
Solution:
Make a .cmd that installs it, and add echo finish at the end so that the .cmd file is sending return code 0(Zero) to SCCM.
If the task sequence is working on all machines and some is failing. The error message would be Hash error, and you would think that every machine will fail. But if the machine have bad memory, then this error will occur.
Solution:
Switch memory with a computer that is working and check if the problem is occuring on the other machine, and the machine that failed is now working.
Then the problem is much likly that you are trying to install x64-bit version of the graphic card on a x86 system.
For some days now I discovered that if you push button1(Picture) or use the keyboard, then tries to use the touchpad it won’t work!

To fix this manually you must enter the Synaptics Settings.

If you have the “problem” you set the slider to minimum. Then the mouse won’t “hang”.
To fix this with registry:
- Use this when you wan’t to set the default value for every user in a deployment: http://humbl.me/s
- Use this when you wanna change the value on the current user that is logged in: http://humbl.me/t
%cd% is available either to a batch file or at the command prompt and expands to the drive letter and path of the current directory (which can change e.g. by using the CD command)
%~dp0 is only available within a batch file and expands to the drive letter and path in which that batch file is located (which cannot change). It is obtained from %0 which is the batch file’s name.
An experiment like the following shows the difference
Here is D:\dirshow.bat:
@echo off
echo this is %%cd%% %cd%
echo this is %%~dp0 %~dp0
Run it from C:\ and this is what you see
C:\>D:\dirshow.bat
this is %cd% C:\
this is %~dp0 D:\

Okei, I have a big problem with video call with Lync on Lenovo T520 with Nvidia Optimus technology. We even tried to use the old Communicator 2007, and it is the same problem.
This is what I have found out so far:
- Removing Nvidia Drivers will fix the problem.
- BIOS : Set display to integrated will fix the problem.
- BIOS : Set display to discerete will fix the problem.
What I think is the problem:
Think the problem is Lync Client, and how it uses the System resource.
anyone with a solution to my problem? =)
