code 0190 critical low battery error- question

[markba633csi]

Do all T400s have this "feature"? Lenovo considers it that, however it makes testing a bare motherboard difficult since both a decent battery and functional board charging system seem to be necessary to boot into the setup menu, and both of those are suspect in my case; the board shuts itself off shortly after the 0190 code appears even though "entering setup" shows momentarily when I press F1. PITA I think I'll wish it into the cornfield....LOL

Yes, them and a whole lot more of other Thinkpads, HP, Dell, you name it.
You've got a (near)dead battery and/or a bad DC-in socket and/or a bad charger.
