Welcome to the ACPI Project on Netlabs

This is the development and support home for ACPI Project.

Much of the information on these pages is out-of-date and is being updated as time permits.

A new version of the ACPI PSD is in development. Information and updates will be posted here.

Testing and Submitting Tickets

Please read the Testing Guidelines page for information on how to test and how to collect information for reporting problems.

You must be logged into TRAC to create tickets. Please login with your Netlabs login id.

If you do not have a login id, you can request one at

If you have troubles acquiring a Netlabs login id send an e-mail to

Netlabs Community Mailing List

If you have open tickets created with the guest login, please add a comment to the ticket showing your new login and we will update the ticket so that you automatically receive e-mail when your open tickets are updated.

Before entering a ticket, please read the Testing Guidelines page for information on how to test and how to collect information for reporting problems.

Milestones and Versions

When entering tickets, you will be asked to provide a version and a milestone.

The TRAC documentation defines these terms as

  • Version - Version of the project that this ticket pertains to.
  • Milestone - When this issue should be resolved at the latest.

For new tickets, the version will default to current ACPI version (i.e. 3.19.02). If you are reporting for some other version, please override the default. If you are opening the ticket for testcase release, please note the testcase version in the ticket summary.

The milestone will default to the next scheduled ACPI version release (i.e. 3.15).

Generally, once a ticket is opened, the version should not be changed. If the issue is not resolved, the milestone will be changed to reflect when the ticket is expected to be resolved.


The ACPI FAQ contains answers to your questions.

See Getting the most from ACPI? for hints from the power users.

The ACPI Tools page contains a wealth of information and links.


New releases and testcase builds are available from the eComStation BetaZone. Log in to Mensys with your Mensys login id and click the Downloads link. Click the "Software Subscription Services for eComStation" Download link and the ACPI drivers should be listed.

You can access the BetaZone from your [ eComStation] login, but the ACPI download may not appear

New releases are announced on the mailing list and elsewhere.

Mailing List

Application / Driver Developers

A toolkit is available for using ACPI services. Applications can link to acpi32.lib and drivers can link to acpidrv.lib. These libraries and header files are included in the toolkit. Sample programs and documentation are provided as well.

You can download the current toolkit here:

ACPI Developers

Getting the sources

In addition to browsing? the sources here, you can check out the sources with your favorite subversion client.

Keep in mind that, unlike cvs, tags and branches are ordinary directories in subversion. With the typical subversion repository layout, it is rather easy to checkout more than you probably intend to. To pull just the trunk version, use something like

mkdir acpi_workspace
cd acpi_workspace
svn checkout trunk

To update your workspace with the current repository content, use

cd acpi_workspace\trunk
svn update

Driver developers that wish to make their drivers ACPI compliant will find the ACPI toolkit useful.
