Backlit keyboard upgrade for Thinkpad Edge E531

Hi all,

 

I've read a couple of postings but have not found a solution for my problem regarding an upgraded backlit keyboard for my E531 which shows no backlight.

 

I installed the keyboard an connected the two flat cables to the mainboard. Other notebook seems to use additional cables for backlighting, but this one seems not to. Unfortunately there is no backlight turning on. When I press Fn + Space instead a space character is typed. There is a lighting key marked on the left side of the space bar model type is KM BL-106D0, FRU is 04Y2399.

 

Any ideas? DoI need to make some settings or adjustments? I bought the keyboard on Ebay, it was marked as compatible with my E531.

 

 

Kind regards

Klaus

I am also having this problem, did you get an answer?

I upgraded my non-backlit keyboard to the backlit style, and it is working perfectly except for the back light. Is this keyboard part number incompatible with this motherboard?
