TITLE:  Bravo MS Erroneous Volt,LANDesk Client
 
 
ISSUE 
 
   LANDesk Client Manager (LDCM) may report Erroneous Voltage 
   threshold values on the Bravo MS system. 
   
   This errata applies to the following systems: 503246-xxx, 
   503247-xxx, 503248-xxx, 503320-xxx, 503322-xxx, 503417-xxx, and 
   503418-xxx.    

 
BACKGROUND 
 
   The allowable power supply voltage deviations for Bravo MS 
   systems are as follows:
   
     Level   Deviation   Range
   
     +12     1.20        +10.8,  +13.2
     -12     1.20        -10.8,  -13.2
     +5      0.50        +5.5,   +4.5
     -5      0.75        -4.25,  -5.75
     +3.3    0.34        +2.96,  +3.64
   
   
   
   LDCM 3.0 indicates error conditions as follows:
   
   1. The error message is displayed in a pop up Windows 
      message.
   
   2. The error message is logged in the Notification Log
      viewable via the 'Notification Log...' option on the 
      'View' menu.
   
   3. The error message is displayed in the scrollable 
      window to the right of the 'PC Health' control.
   
   A voltage threshold error message might include the following 
   text:
   
      "The voltage supplied by your computer's power supply 
      is not within manufacturer's specifications."
   
   These versions have been updated to correct voltage threshold 
   logic bugs manifested by a LDCM 3.0 error message. This error 
   message indicates that a voltage problem exists when in fact, the 
   voltage value lies within the threshold range.    

 
ACTION 
 
   If a Bravo MS system user indicates that their system indicated a 
   "Critically Low" or "Critically High" voltage problem, do the 
   following:
   
   1. Ask the user to activate the "PC Health" control on 
      the main LDCM 3.0 window. Then ask the user to read 
      the 'Current' values in the "Power Supplies" table.
   
   2. Determine if all of the values are within the ranges 
      listed above. 
   
   3. If all current voltage values are within their 
      allowable range, it is possible that the error 
      indication was erroneous.
   
   4. If an erroneous voltage indication is suspected, the 
      problem might be corrected by replacing the 
      CILM7895.EXE or the CILM78NT.EXE modules (as 
      appropriate). To do this, follow the steps below:
   
      a. Obtain file CILM7895.EXE or file CILM78NT.EXE from 
         one of AST's On-Line! services as follows: 
   
         AST WWW Site:  http://www.ast.com
         AST On-Line! BBS*:  See IB0001.TXT
         CompuServe:  GO: ASTFORUM
         Prodigy:   JUMP: ASTSUPPORT
   
         * Refer to IB0001.TXT for a list of AST's   
           international BBS numbers.
   
         To decompress this file, create a temporary 
         directory on your hard drive, copy the downloaded 
         file to that directory, and run the file.     
   
      b. Delete file CILM95.EXE or CILMNT.EXE from the  
         C:\DMI\SIA\BIN directory.
   
      c. Copy downloaded file CILM7895.EXE or CILM78NT.EXE 
         into C:\DMI\SIA\BIN.
   
      d. Rename file CILM7895.EXE to CILM95.EXE or 
         CILM78NT.EXE to CILMNT.EXE, depending on the 
         corresponding operating system.
   
      e. Reboot the system. 
   
   The system will now report the correct voltage.
