I am new to submitting bugs do I need to change the status of this request now?

I have added the neededinfo but not sure what status to change it to,

This is the latest June bios update as well.  How do I go about contacting Lenovo on an unsupported device.

Also who's responsibility is it to fix the AML bytecode issues?

(In reply to kernelbugs from comment #9)
> Also who's responsibility is it to fix the AML bytecode issues?

It would have to start at Lenovo. I would suggest contacting their customer service to see if they can do anything about this. Since this AML should be fixed by Lenovo, this isn't a kernel bug. I'll close this for now but if there is a kernel issue related to this, feel free to reopen.

Ok I have contact customer service about this back when this happened and never heard anything back about it. Does the kernel team have a way to push this as I seem to now have the same problems on a t440p that I purchased so it is not just the t450.

Bug closed as this is not a kernel issue.

CC Peter to see if we can get the buggy ACPI ASL code fixed.
