AW11M: Windows 7 -> Backlight Keys not working propery

[dartrax]

Hello,

I just updated to Win7.

Now the backlight key to increase backlight is not working properly:

It increases LED Backlight brightness up to 40%. Then it falls back to 0% but never goes higher than 40%, unless I change backlight brightness in Win settings panel.
The On-Screen-Indicator shows up accordingly.

thank you,

Hello Thalamus!

Yes, I have installed NVIDIA Graphic driver 8.15.11.8640. That's the newest one from Sony support page. I've also installed all the 7UPG utilities.

I've already installed the Event Service twice (the first time nothing happened after a short install, the second time install took longer and changed the behavior of backlight brightness keys, but they do not work better now. You'll get a screenshot tomorrow so you can see it clearly.)

I would like to install Event Service and Shared Library once again, and in this particular order that i've found here:

1) SFEP (Sony Firmware Extension Parser) driver
2) reboot
3) VAIO Event Service
4) reboot
5) Sony Shared Library
6) reboot

But I need the SFEP driver first. My current version is 8.0.1.1 from March 15th, so it's not especially for Win 7.
Any ideas where I can find them? They do not appear at the support page for AW11M.

Thank you,
dartrax

I think we are struggling on this, but if there is no Win 7 upgrade for this driver then I can only assume that the original Vista driver should work. Many of the original Vista drivers work under Win 7.

Hello!

This morning I really had to take care not to fall off from the chair.

I do not now what has happened. It's just working now the way it is supposed to work.

The only thing I did was rebooting the vaio over night and connect it to another monitor via HDMI. I have no clue what might be responsible for this.

So I hope this will never fail again...

Thank you for all your suggestions!
