T620 "The TCM battery has failed"
About every hour our so, the OpenMnage Server Administrator reports in the the Hardware Log a "The TCM battery has failed." message and then within about a minute reports a "The TCM battery is operating normally" message. I am familiar with the System Battery and the RAID Controller battery but now the TCM battery. What is the TCM Battery?

Hello
I am unable to locate information on the error you are receiving. The only TCM I'm aware of is the Trusted Cryptography Module. It is the version of the TPM that we install for systems sold in Russia and China. It does not have its own battery. It uses the CMOS battery. I suggest locating the event ID for the error and locate that ID in the message reference guide for OMSA:

Getting exactly the same message on a T620 at a customer in USA on a US spec'd and purchased server. started about 3 days ago. Really annoying and fills up the hardware log but quick. Maybe Julian Assange can shed some light on this Russian problem? LOL!
So is it the RAID controller battery or the BIOS battery?

Description The controller write policy has been changed to Write Through.
Severity Warning
Cause and Action Cause: The controller battery is unable to maintain cached data for the required period of time. For example, if the required period of time is 24 hours, the battery is unable to maintain cached data for 24 hours. It is normal to receive this alert during the battery Learn cycle as the Learn cycle discharges the battery before recharging it. When discharged, the battery cannot maintain cached data.
Action: Check the health of the battery. If the battery is weak, replace the battery pack.
