# HP EliteBook 2170p

This page is about the notebook [HP EliteBook 2170p].

## Release status

HP EliteBook 2170p was released in 2012 and is now end of life.
It can be bought from a secondhand market like Taobao or eBay.

## Required proprietary blobs

The following blobs are required to operate the hardware:
1. EC firmware
2. Intel ME firmware

EC firmware can be retrieved from the HP firmware update image, or the firmware
backup of the laptop. EC Firmware is part of the coreboot build process.
The guide on extracting EC firmware and using it to build coreboot is in
document [HP Laptops with KBC1126 Embedded Controller](hp_kbc1126_laptops).

Intel ME firmware is in the flash chip. It is not needed when building coreboot.

## Programming

The flash chip is located between the memory slots, WWAN card and CPU,
covered by the base enclosure, which needs to be removed according to
the [Maintenance and Service Guide] to access the flash chip. Unlike
other variants, the flash chip on 2170p is socketed, so it can be taken
off and operated with an external programmer.

Pin 1 of the flash chip is at the side near the CPU.
