Your issue is not easily fixed because there is many laptop with broken acpi which report wrong lid status (some of them always report lid closed what ever is the lid status, other always report lid open, ... i am not expert on how broken this is but from what i have been told i should rather consider drinking than trying to look into it and then go to the drinking step). Bottom line is that lid detection is unreliable thus so far we ignore it silently. I think the plan is to monitor lid status change and if we detect change from either open to close or close to open then we can start assuming that acpi lid status is reliable and act accordingly.
