New Samsung laptops (NP530U3C, NP900X4B, NP900X3C, ...) also have an EC which isn't supported by the generic ACPI driver. The lid, the battery status and the power supply status are connected to it. How did you implement the EC support in the thinkpad driver? Did you have documentation or was it done by reverse engineering? Could you have a look at the related kernel bugzilla bugs?: https://bugzilla.kernel.org/show_bug.cgi?id=3D45461 https://bugzilla.kernel.org/show_bug.cgi?id=3D44161 Cheers, Sebastian --=20 Sebastian Riemer Linux Kernel Developer - Storage We are looking for (SENIOR) LINUX KERNEL DEVELOPERS!
