# Fixing Embedded Controller (Laptop)
This one's fairly easy to figure out, open your decompiled DSDT and search for `PNP0C09`. This should give you a result like this:

As you can see our `PNP0C09` is found within the `Device (EC0)` meaning this is the device we want to rename.
> What happens if multiple `PNP0C09` show up
When this happens you need to figure out which is the main and which is not, it's fairly easy to figure out. Check each controller for the following properties:
* `_HID`
* `_CRS`
* `_GPE`
Note that only the main EC needs renaming, if you only have one `PNP0C09` then it is automatically your main regardless of properties.
# Applying your EC patch
As you can see from the table below, we'll be renaming our EC listed in the DSDT. Do note you cannot just throw random renames without checking first, as this can cause actual damage to your laptop.
