This is a beastly 15" Sandy Bridge platform from HP. It has upgradeable
graphics in the MXM-A 3.0. Only the Quadro 2000M that shipped with some
of these laptops is tested with Libreboot so far. 1000M is expected to
work as well. The very newest modules might not work, because the internal
panel is an LVDS one. Newest GPUs supposedly only support eDP panels.

GPU
---
This laptop has upgradeable GPU: it has a socketed MXM-A 3.0 card. So far,
only Quadro 1000M and 2000M (which shipped with the laptop originally) have
been tested with Libreboot.
These laptops shipped with eDP and LVDS panels. If you choose to upgrade the
graphics card, make sure it is compatible with the panel you have. Use the
following command to check:
xrandr
Or if using Wayland:
wlr-randr
If you have "LVDS-1 connected", your GPU upgrade needs to support LVDS.
According to [this forum thread](https://forums.macrumors.com/threads/2011-imac-graphics-card-upgrade.1596614/),
AMD's 1st gen GCN cards are the newest and most powerful to support LVDS.
If you have an eDP panel, you should be able to use newer cards than that.
As long as the card has an onboard VBIOS, Libreboot will execute it and
everything *should* work. **However, this is currently untested.**
