== Stable Support ==
coreboot ports for these machines work with a wide range of peripherals (in some cases supporting more hardware than their stock firmware), have reliable hardware-based fan control, and have been deployed successfully by 15h.org community members. Review the corresponding [[Motherboards|motherboard]] page for any remaining missing or untested features. For source, see [https://git.15h.org/mrothfuss/coreboot-15h our git forge].

== Alpha Support ==
coreboot ports for these machines are capable of booting, but are missing important functionality and are unlikely to be suitable for non-development use. If you have one of these machines, consider helping test or develop [[coreboot-15h]] on it!

The Lenovo ThinkPad X140e is an 11.6" laptop using AMD's fam16h [[Kabini]] SoCs.

== Open Source Firmware ==
Open source firmware for the X140e is provided by [[coreboot-15h]] utilizing AMD's open source AGESA release for platform initialization. The git repository for the firmware can be reviewed [https://git.15h.org/mrothfuss/coreboot-15h here].

=== coreboot-15h ===
{{Excerpt|Coreboot-15h|[[Lenovo ThinkPad X140e]]|hat=no}}

=== Missing Features ===
* The system fan does not turn off during S3

=== Flashing ===
[[File:X140e flash1.png|frameless|200x200px]]
[[File:X140e flash2.png|frameless|200x200px]]
[[File:X140e flash3.png|frameless|200x200px]]

To switch from the stock firmware to coreboot, [[External Flashing | external flashing]] is required. Before switching to coreboot, make sure you are using the latest OEM BIOS to ensure the latest EC firmware is on your device. The SOIC-8 flash chip is easily accessible from the bottom of the laptop. With the rear panel removed (3 screws), the flash chip is under a piece of black tape and next to the RAM. A Pomona 5250 clip is recommended over generic clips to avoid colliding with the chassis frame. A 3.3V programmer should be used; flashrom will need the "-c W25Q32FV" argument to flash the chip. The CMOS should be cleared when switching to coreboot, the battery is next to the flash chip and can be disconnected to wipe the CMOS.

=== Debugging ===
This laptop does not have a serial port. Because of this, the most practical way to get debug output from coreboot is via [[EHCI Debugging]]. Connect your EHCI debugging device to the yellow always-powered USB 2.0 port immediately next to the power input jack.
