=== 1.1. Misc troubles ===

Q1: Trap before PMSHELL
A1: You forgot to remove IBM APM.SYS


Q2: Which applications/drivers are not compatible with APM.ADD? 
A2: Users report:
     * old Genmac 1.0 driver causes TRAP0008 when netbind.exe loads. 
       Upgrade to Genmac 1.7 or higher.
     
 
Q3: Power Off hangs notebook
A3: Check BIOS Setup.
       Wake On LAN from System Off = disabled

       
       
Q4: Power Off doesn't work
A4: AcpiD.cfg should contain line:
        PowerButton = Off
     
    
Q5: Battery widget shows 255%
A5: Open "Power object" -> properties, 
    check "APM BIOS and OS/2 support enabled" is selected

    
Q6: Battery widget shows E87
A6: Try: 
    1) Open "Power object" -> properties, 
         check "APM BIOS and OS/2 support enabled" is selected
    2) Install Beer Battery widget 
         http://ecomstation.ru/projects/neowps/?action=widgets 
    3) Check the intallation instructions again: APM.doc -> Installation
    4) Try change Speedstep options (and similar parameters) in BIOS setup
    
        
Q7: Shutdown doesn't work properly    
A7: Try Power off the PC using PowerOff.exe, if it works then the problem
    is caused by the shutdown utility (eWorkPlace -> eShutdown, eStyler)
    
    
Q8: acpi daemon doesn't traps, doesn't work properly
A8: Do you use correct version of acpi32.dll? 
    

Q9: eCenter hangs..
A9: load acpi daemon, CRC from startup.cmd, not startup folder.


         
Default:       

Boot with APM.ADD driver and execute command: 
 copy apm$ apm.log 
 
send  apm.log to the tracker



=== 1.2. Suspend/resume ===

troubleshooting:

Q1: Computer goes to suspend and immediately resumes.
A1: * it's necessary disable some devices, send the output of gpedevice.exe
     to the developers of ACPI.
   * make experiment: disable modem, detach ethernet cable, disable wifi
      does the problem repeat in this case?
   
      
Q2: How to understand why suspend crashes?      
A2: use debug ACPI
   fullscreen session
   apm /suspend
   look at the last line, example: 
     SCREEN$  => use Panorama VESA instead of SNAP

     
Q3: Trap on suspend to S1       
A3: Do you have Intel 10/100 netcard? This is the cause of trap. 
    Use Realtek adapter..
    
    
Q4: Suspend hangs       
A4: Try different methods to start daemon:

    GOOD METHOD, 
    From startup.cmd    
      start /min ACPIDAEMON.EXE    
      
    from StartUp folder - BAD method (??)
      
    BAD METHOD: (??)
    From CONFIG.SYS
      method 1:
        RUN=X:\OS2\CMD.EXE /C X:\OS2\ACPIDAEMON.EXE
      method 2:     
        RUN=x:\OS2\ACPIDAEMON.EXE
