Solved I'cant read baterry status

Freebsd 12, when I run acpiconf -i 0 or 1,2 i get:

acpiconf: get battery info (0) failed: Device not configured

even with the acpi_ibm module loaded

in dmesg I had this :

Code:
ACPI Error: No handler for Region [ERAM] (0xfffff80003536680) [EmbeddedControl] (20181003/evregion-288)
ACPI Error: Region EmbeddedControl (ID=3) has no handler (20181003/exfldio-428)
ACPI Error: Method parse/execution failed \134_SB.BAT1._STA, AE_NOT_EXIST (20181003/psparse-677)
cpu0: <ACPI CPU> on acpi0

I get the correct readout on my FreeBSD 12.0-RELEASE box. I built mine from scratch and didn't upgrade if it makes any difference:

Is strange, me too,build from scratch and never hace problems with the t400 , maybe updating the bios?

edit, I even had the webcam working, something that never...never had working even on Linux
also had problems to resume

Trihexagonal , what bios version do you have?
 
Mine is a T61 with:

BIOS Version 2.17 (7LETB7WW)
BIOS Date 2008-04-25

It's what was on it when I purchased it and I've never updated the BIOS on any of mine. I do show a couple Firmware error warnings when I run dmesg on the T61 but everything is running normally.

I have a T400 but it's still running 11.2 and it gives the correct readout for the command. The BIOS on it are:

BIOS Version 3.12 (7UET82WW)
BIOS Date 2010-01-13
