Subject: Determining whether the system is on AC power or not
Date: Tue, 7 Feb 2006 15:52:44 +0000 [thread overview]
Message-ID: <20060207155244.GA4919@srcf.ucam.org> (raw)
It would be helpful for drivers to be able to determine whether a system
is currently on AC power or not (for instance, cases where backlight
brightness is stored separately for AC and DC). There currently doesn't
seem to be any way to export that information from the ACPI drivers.
Would it be reasonable to add a mechanism for doing so?
