Anyway I've chosen a new keyboard with backlight. Everything is well connected (the backlight connector too) but the backlight is not working.
I've read various topic on the forum about using from command prompt as an administrator:WBT.exe -C CNFG/ W DD 7C
Without any luck I've got some errors ( Ndrivrs Failed) and return code 0.
Do you have any suggestions ?
Many thanks for your appreciated help
