Hi Carlos, Sorry bother you for this old issue. æ äï2011-01-03 æ 20:49 +0000ïMatthew Garrett æåï > It looks like this GUID is present in a surprisingly wide range of > devices (eg, http://pastebin.com/8BY0Dg64 from a Vaio...), which means > that it's probably not a safe assumption that reading from the EC will > give us reasonable results.

For Lenovo Ideapad, that will be better handle by ideapad-laptop driver. Could we just direct add those model to the blacklist in acer-wmi driver? or we direct check dmi in acer-wmi for only support Acer machines that were included AMW0 in DSDT? Appreciate if you can give any suggestion. Thank's a lot!
