Bug ID: 230428
Summary: No battery detected on Thinkpad x230 with coreboot
bios
Product: Base System
Version: CURRENT
Hardware: amd64
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: misc
Assignee: b...@freebsd.org
Reporter: ali...@gmail.com
This machine has been running well on FreeBSD with the stock bios. I decided to
flash coreboot 4.8.1 to get rid of the wireless card whitelist, so I can
install any card I want. Also I've got rid of Intel ME.
FreeBSD Current does not detect the battery, dmesg | grep ACPI gives the
following
ACPI APIC Table: <CORE COREBOOT>
ACPI Error: No handler for Region [ERAM] (0xfffff80003672200) [EmbeddedControl]
(20180629/evregion-288)
ACPI Error: Region EmbeddedControl (ID=3) has no handler (20180629/exfldio-428)
ACPI Error: Method parse/execution failed \134_SB.PCI0.LPCB.EC.BAT0._STA,

For info, a debian live bootable image detects the battery with no issue.
