IBM PS/2 - 8556 and 8557 display 161 battery error
Applicable to: World-Wide
Symptom:
The 8556 and 8557 system unit may display a 161 POST error. Battery replacement and subsequent reconfiguration are performed, however an error reoccurs intermittently.
Problem Isolation Aids:
The 8556 or 8557 may be connected to a Network.
Fix:
Before replacing the battery it should be checked with a meter. For correct machine operation the battery voltage should be between 2.5 volts and 3.7 volts.
161 errors may occur if the voltage on the battery drops below 2.5 volts.
To check the battery voltage:
-Turn off the system unit power.
- Remove the battery from the battery holder.
- Check the battery for a voltage of 2.5v - 3.7v DC.
If the battery voltage drops below 2.5 volts, it should be replaced with FRU P/N33F8354.
After replacing the battery, the system unit should be powered on and checked for proper operation.
Problem determination has shown that some workstations connected to Networks may have their time and date or configurations inadvertently changed during Network operations. Upon a subsequent boot or reboot of the workstation the system detects this change, interprets it as if the battery went dead, and the workstation posts the 161 battery error. The customer should be referred to their network administrator or software support centre for assistance in a solution to this problem.
An attempt should be made to understand what jobs and application programs are being run, on the network and/or customers work station that may cause this error to appear. This information would be helpful in identifying the cause of the problem. Programs that do network interrogation, backups, etc. may be a cause of this problem.
