Two days ago, I decided to install Windows 8.1 operating system on my Dell E6400 laptop. I have to admin that this laptop has served me well over the last 4years. The only complaint I had for it was WWAN module drivers for Windows 2008 or windows server 2012 which don't work. I searched for the driver heaven and earth and could not find them. Then one day, a driver was discovered by driver update and was loaded. But it never worked.

Back to Ambient light Sensor. The Ambient Light Sensor (ALS) on a dell computer is responsible for automatically adjusting the brightness of the laptops LCD screen based on lighting conditions. While running windows XP, Vista, windows 7 and windows server 2012 on this Dell E6400, the LCD always worked. However this time around, two days after installing Windows 8.1, My Dell laptop started acting up. The screen would  switch off randomly while I am working. In some cases I had reboot the laptop, to get it working again.

 The symptoms exhibited are similar to the one where LCDs backlight is/has failed. I could see the windows icons on the dark gray ground of the LCD. What puzzled me is the fact that this would only happen when the PC was running Windows 8.1.  After a while, it dawned on me, there is an ambient light sensor and it became number 1 suspect. I browsed through my device manager,  and for some reason, it was missing, Therefore in my opinion, driver not loaded.

To get me back to working, I went into bios, and disabled Ambient Light Sensor. Since then my LCD screen does switch off erratically. This yet another case chemistry gone wrong.
