M4600 & Windows 8

I tried installing Windows 8 on my M4600 today. There are a few things not working the way I would have expected and I'm wondering if anyone else is having the same issues.

1. Screen brightness adjustments don't work - I installed the newest DFEP 2.2.1 and still no go.
2. Dell hasn't posted Intel GMA HD 3000 drivers yet for Windows 8
3. Dell hasn't posed Nvidia 2000 drivers yet
4. No chipset drivers either.

.. Windows does seem to work okay, I question my battery consumption though - I think Windows 7 had better battery life but I wonder if that is just a function of driver maturity.

Looking forward to hear other peoples comments on this - Thanks.

 

The brightness control is a function of the graphics driver, not the DFEP.

Use the M4700 drivers for the Intel GPU (also supports the HD 3000) and you should get brightness control:

For chipset drivers, I'm not sure if you need them, but... I'm using Dell's posted 64-bit Windows 7 drivers (on M6700) and that seems fine. The M4700 drivers should work on the M4600 as well here.

It doesn't look like Intel has posted a Windows 8 chipset install utility on their site yet either.

NVIDIA drivers should be available on Windows Update.

 

Screen brightness is from display driver.

 

I just complete the Windows 8 Installation today on my M4600, as well from a clean installation.

I couldn't manage to find the correct Broadcom w/ Swipe (I believe, it mean Fingerprint). Also, the Finger Gesture at Trackpad for new Windows 8's start screen.

Do you guys have any luck on this?

 

Are your brightness controls working?

 

Installed Win8 yesterday. My M4600 brightness control also doesn't work.

I also noticed that the power-plan doesn't have an option for cool-mode. And whenever the fan turns on it runs at full speed.

 

I have the same problem on M6700. No fingerprint drivers yet, unfortunately.

Has anyone tried the drivers I linked to above for brightness control?

 

I tried them and still no go, I don't personally believe that the graphics drivers are tied to brightness control.. I think the brightness is more of a chipset function becuase you can make adjustments from the bios.

 

I mention it because plenty of people have reported (under Windows 7) that you have to use Dell's GPU drivers to have brightness control, if you install the GPU drivers from Intel then you lose it.

 

*** SOLVED *** I noticed through the device manager that the computer had 2 display adapters in play. It was using the basic Intel, and not the Nvidia Quadro 1000M I had as well.

I went into the BIOS (Press F12 during the restart) and turned off the "Optimus" option off. Now it works. (And the intel display adapter no longer appears in the device manager)

Hope that works for others!
