Other components may remain powered so the computer can "wake" on input from the keyboard, clock, modemLANor USB device G3 Mechanical Off The computer's ACPI Module has been totally removed via a mechanical switch as on the rear of a PSU.

The power cord can be removed and the system is safe for disassembly typically, only the real-time clock continues to run using its own small battery ACPI Module specification also defines a Legacy state: The device states D0—D3 are device dependent: D0 or Fully On is the operating state. D1 and D2 are intermediate power-states whose definition varies by device. One writes a magic value to this command port to generate an SMI. Interaction with the Embedded Controller This is where really difficult to diagnose issues occur. The Embedded Controller EC contains proprietary code to control peripherals.

The naming convention is as follows: The EC command port location ACPI Module be found by using: Hence most Lenovos share the same basic functionality mappings onto the EC memory, which enables one to figure out which memory location may be used for specific features. Since these fields are proprietary there is scant documentation ACPI Module a lot of the debugging at this level is down to intelligent guesswork and reverse engineering the AML methods to figure out what how the EC works. Section 5.


General-purpose events can be raised from a GPE bit tied to an embedded controller. Note that query event code 0x00 is reserved - it indicates that there are no outstanding events. Note how they store lid state and then generate a LID notification. Then as root, enable debug as follows: These titles must be distinct from any other section titles. You may add a section entitled "Endorsements", provided it contains nothing but endorsements of your Modified Version by various parties--for example, statements of peer review or that the text has been approved by an ACPI Module as the authoritative definition of a standard. Only one passage of Front-Cover Text and one of Back-Cover Text may be added by or through arrangements made by any one entity. If the Document already includes a cover text for the same cover, previously added by you or by ACPI Module made by the same entity you are acting on behalf of, you may not add another; but you may replace the old one, on explicit permission from the previous publisher that added the old one.

Make the same adjustment to the section titles in the list of Invariant Sections in the license notice of the combined work. In the combination, you must combine any sections entitled "History" in the various original documents, forming one section entitled "History"; likewise combine any sections entitled "Acknowledgements", ACPI Module any sections entitled "Dedications". You must delete all sections entitled "Endorsements. You may extract a ACPI Module document from such a collection, and distribute it individually under this License, provided you insert a copy of this License into the extracted document, and follow this License in all other respects regarding verbatim copying of that document.

Such a compilation is called an "aggregate", and this License does not apply to the other self-contained works thus compiled with the Document, on account of their being thus compiled, if they are not themselves derivative works of the Document. If the Cover Text requirement of section 3 is applicable to these copies of the Document, then if the Document is less than one quarter of the entire aggregate, the Document's Cover Texts may be placed on covers that surround only ACPI Module Document within the aggregate. Otherwise they must appear on covers around the whole aggregate.
