Thanks. I've tried with these but the sleep doesn't really work. The fan still spins while sleeping but I'm comfortable with it.
USB patch: As HervÃ© said above, I just search and replace EHCI to EHC1.
Battery patch: Some guys here and I had issue with battery. Then I ask RehabMan about this issue and he told me that the problem is the second battery object in DSDT, but is not present. Disable it by:
into method label _STA parent_label BAT1 replace_content begin Return(0) end;
Other patches (optional): Use Dell E6410 in http://olarila.com/forum/packs.php. Be careful to remove patches related to EHCI because they don't work any more. Use the USB patch above. Actually I'm not sure what these patches do but there's not harm in trying.
