Hi. I am experiencing an issue with the back-light display control under Windows 7 x64 on my Samsung N150. Basically, the back-light remains constant and there’s no way to turn it down. I have installed Samsung Display Manager with the Intel x64 video driver.
This is an outline of what’s happening:
– LCD back-light remains at a constant level the whole time under Windows 7
– I have Samsung Display Manager installed/running
– fn keys doesn’t do anything for adjusting brightness level
– fn + f5 does turn on/off back-light, and all fn keys does work except screen back-light control not working
Any advice on how to get back-light brightness control working? I appreciate it.
This topic has been raised several times – search further down this Forum. you need to restore a previous Intel Graphics driver.
Thanks jirams.
I found my solution from this thread:

The trouble I was having was that the Intel driver on Samsung’s Website are all 32-bit only, while I had x64 version of Windows 7 installed. I managed to use Google as my friend to track down the older version of the Intel Display Driver for GMA 3150 in x64 flavor and solved the brightness lock issue.
Here is Intel’s link to the x64 version of the video driver described in the linked thread (8.14.10.1972):

Cheers!
So win 7 x64 runs OK on the N150? The older atoms could never run 64 bit operating systems and I assumed the newer ones couldn’t either.
I think it is more to do with a duff driver as the fault has now been widely reported. The latest one I have for my N150 is this:8.14.10.2108
