17 R4, motherboard connectors manufacturer code?

Hi, 

I have an Alienware 17 R4 notebook which has expired warranty and some of connectors broken and needs to be replaced. Could you please help me to identify these connectors manufacturer code or digikey part number?

I just need to identify connectors labelled KB_BL (has 20 positions or pins) and KB (has 30 positions or pins)

Connector Label: JKB (20 positions FPC)
