Hi @herotix ,
I don’t know the answer but here’s the [http://h10032.www1.hp.com/ctg/Manual/c06297505|maintenance and service guide] for the laptop taken from this [https://support.hp.com/au-en/product/hp-chromebook-11-g6-ee/18280450/manuals|webpage].
On p.10 of the guide you will find the various part numbers for all the country specific keyboards / palmrest assemblies available for the model.
I don’t know if these keyboards are backlit or not but perhaps if you open the laptop as per the guide, you may be able to find the keyboard (or palmrest keyboard assembly) part number printed on your assembly and then search online using that part number ''only'' in the search term of your browser to find suppliers of the part. Unfortunately it may involve completely dis-assembling the laptop.
Just an idea.
