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 32 Bit 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.) Page 2 of 12 The following list identifies LAPTOPS computers that have Advanced Power Management support in conformance to the APM 1.0 Specification (dated 1/91) and includes the level of APM conformance. (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 are are also identified. The following list of laptop systems is incomplete and represents only the systems tested as of April 19, 1994. This list will be updated as additional systems are checked for OS/2 2.1 APM compatibility.

Would require extensive hardware changes to support APM. For OS/2 2.1 APM, access the IBM BBS and download the following three files: 1. TGSFX.COM (located in file area 4) 2. RFL40SXA.TG0 (located in fila area 27) 3. L40PWR.ZIP (located in file area 37) Execute the TGSFX.COM to install the TELEGET.EXE program. Then create a new L40SX reference diskette by using TELEGET.EXE to unpack the RFL40SXA.TG0 onto a 1.44MB formatted diskette. Use PKUNZIP to unzip the L40PWR.ZIP. Then replace (i.e. COPY) the files IDLE.EXE and PWRMGMT.SYS onto the newly created L40SX reference diskette with the ones obtained from unzipping L40PWR.ZIP. Reboot L40SX with resulting reference diskette in the A: drive and configure with APM. Verify the APM configuration with the view configuration, exit configuration and do a power up reboot to OS/2. IBM P/S NOTE, Model 2141 - No APM support in BIOS. This is a non-APM machine. For OS/2 2.1 use Function F1 to get the configuration panel displayed and set both the "Resume on Ring" and "Resume on Alarm" to OFF, also make sure APM driver is not there (i.e. APM not installed.) Remove the following two APM device statements from the CONFIG.SYS: "DEVICE=C:\OS2\APM.SYS" "DEVICE=C:\OS2\MDOS\VAPM.SYS" Delete these two files from the corresponding hardfile subdirectorys. This gains about 1 second in bootup and frees up hardfile space. IBM P/S NOTE 425, 425c - BIOS Supports APM. Has 16 Bit Protect Mode APM, and 32 Bit Protect Mode APM.

On systems with OS/2 2.1 base apply PJ08807. The OS/2 APM calls into the BIOS APM once per second to check if it is OK to do a suspend. The Twinhead SubNote BIOS (Phoenix NoteBIOS 486/OPTi463 Version 1.03 and PhoenixMISER V2.0) does not return the OK to suspend on these OS/2 APM calls if there is any video display activity/changes for the duration of the CMOS suspend timeout. The battery level is not operative since the popup "Unknown Power Source, Unknown Battery" is displayed by the OS/2 APM.
