T420s battery shows no details in powermanager

[Rose]

I have two main batteries for my T420s. Both with different FRU's. None of them show any info in power manager at all. No manufacture date, no design capacity, no cycle count, no nothing.

First, only one of the batteries stoped showing data, while the other stopped later. Ive tried uppdating the powermanager but does not help. Doe's anyone have a clue to what the problem is?

That seems unusual. Maybe you want to uninstall/re-install power manager.
