Dell Latitude E5520

Return to index

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. This is a known bug, but otherwise the machine will be mostly stable.

Libreboot 20231021 and releases newer than this have ROMs available for Dell Latitude E5520.

ROM images for Dell Latitude E5520 are available for flashing in the Libreboot releases after 20230625, or you can compile a ROM image for installation via lbmk, see: build instructions

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

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: E5520 installation instructions
