**Thermal safety**: this machine shuts down very quickly, when the machine
exceeds 80c CPU temperature, which is far more conservative than on most
laptops (non-Dell ones), so you should make sure that your thermals are
excellent. More info available [here](dell_thermal.md). This is a known bug,
but otherwise the machine will be mostly stable.

Introduction
============

**Libreboot 20231021 and releases newer than this have ROMs available for
Dell Latitude E6420.**

ROM images for Dell Latitude E6420 are available for flashing in the Libreboot
releases *after* 20230625, or you can compile a ROM image for installation via
lbmk, see: [build instructions](../build/)

Only the Intel GPU variants are supported, currently. All models with Intel GPU
are assumed to work.

Unlike the E6400, this one does require a neutered Intel ME image to run. This
means running it through `me_cleaner` before flashing; the Libreboot build
system does this automatically, during build, or you can insert a neutered
ROM image using the vendor scripts, see guide:

[Insert vendor files](../install/ivy_has_common.md)

As with the E6400, this one is flashable in software, from Dell UEFI firmware
to Libreboot. Please refer to the installation instructions.

**To install Libreboot, see: [E6420 installation
instructions](../install/e6430.md)**
