 hardware on many xx30 series laptops and make almost every key work properly.
 The only keys that are not working are Fn+F3 (Battery) and Fn+F12 (Hibernate)
 
-Unfortunately, it turns out that not all xx30 series thinkpads have the same
-BIOS and EC arrangement - some do not have a "FL2" file in the BIOS update
-image and thus the location of the EC to patch is missing.  This is known to
-be the case with at least the L530.
+Unfortunately, there are a small number of thinkpads with a model number
+from the "xx30" series that are using a completely different EC CPU and
+a different BIOS update strategy.  Thus they are not currently able to
+be patched.  This is known to be the case for at least the L430, L530
+and E330.
