- OS/2 ADVANCED POWER MANAGEMENT SUPPORT FOR LAPTOP COMPUTER SYSTEMS
- ==================================================================
-
- Every laptop has its own unique set of power management features (i.e. blank
- screen after x minutes, press special key sequence to go to standby or
- suspend mode, automatically go into suspend after x minutes of inactivity,
- etc.). If a laptop uses a DOS power management device driver to provide
- these features when running real mode DOS, they will not work under OS/2.
- If these features are implemented in the laptops firmware they will continue
- to work under OS/2 whether the OS/2 APM support is installed or not. Once
- OS/2 APM is loaded, the OS/2 power object is available and provides the
- ability to determine power source, battery life, the ability to suspend on
- demand, etc. (see power object). If OS/2 APM support is not installed,
- users cannot perform these additional features. This does not have any
- impact upon the features that are built into the particular laptop.
-
- * Laptop Computers compatible with OS/2 2.1 Advanced Power Management will
- have 16 Bit Protect Mode APM in the BIOS.
-
- * Laptop Computers that have 32 Bit Protect Mode APM will require fix
- PJ08807 with the OS/2 2.1 base. (OS/2 2.1 GA has support for 16 Bit
- Protect Mode APM. The PJ08807 fix simply adds 32 Bit Protect Mode APM
- support to OS/2 2.1 GA.)
-
- * Laptop Computers that have either 16 Bit Protect Mode or 32 Bit Protect
- Mode APM and have OS/2 2.1 with Service pack (XR06200) will require
- PJ12413. The PJ12413 fix corrects the Protect Mode APM support in
- OS/2 2.11 (XR06200).
-
- * Laptop Computers that have "No APM support in BIOS" or only have Real
- Mode APM are not supported by OS/2 2.1 Advanced Power Management since
- OS/2 is a Protect Mode only operating system. (Note: OS/2 does not
- support the Real Mode APM since the OS/2 module VAPM.SYS does not
- emulate the APM BIOS in a VDM session.)
-
- The APMHERE program can be used to identify LAPTOP computers that have
- Advanced Power Management support in conformance to the APM 1.0 Specification
- (dated 1/91) (Note: Systems with BIOS dates prior to January 1991 will not
- have the protect mode APM support in their BIOS.) Laptop computers that do
- not have any APM support in their BIOS will also be identified.

-
- To run APMHERE.EXE:
-
- 1. Disable any DOS Power management drivers that are loaded with DOS.
- (See contents of the DOS CONFIG.SYS file for the DOS Power Management
- device drivers.)
-
- 2. Boot native DOS (with the DOS power management drivers disabled).
-
- 3. Run APMHERE.EXE. Redirect output to a file to save the information.
- For example enter the command: APMHERE.EXE > APMOUT.TXT
-
- 4. Please also record the BIOS information displayed during a power up
- reboot. Include the BIOS vendor, version, dates, etc.
