Had I read through the EC code earlier I would have spotted that one. So, my apologies for wasting your time with this. So, what I need to do is update WMI to install a handler for the EmbeddedControl region in PNP0C14. Alexey - I suspect the easiest way would be to make such a handler just call ec_read & ec_write, and let the EC driver do the real work, rather than trying to do anything more complicated in WMI? -Carlos (Hoping WMI doesn't keep throwing up more "surprises"...) -- E-Mail: carlos@strangeworlds.co.uk Web: strangeworlds.co.uk GPG Key ID: 0x23EE722D
