Outdoor Light Sensor

We are looking for a better place for the outdoor light sensor in a future laptop, where we have a chance to make minor changes in the mainframe tooling. The problem with the current location is: interference from LEDs (noticeably the storage LED, with which it shares a package and light-guide)

The rear facing storage LED is of less use, since when storage latency is important to a user they are typically also operating the unit from the front. There is no display backlight leakage that I can see through the rear facing light pipes. However, this mounting point would capture light
