HP EliteBook 840 Aero G8 Motherboard Replacement

Introducción

This guide will demonstrate the replacement of the motherboard of an HP EliteBook 840 Aero G8. This replacement may be necessary as a last resort fix for a computer, as individual parts will usually break before a motherboard does. The main reasons to replace the motherboard will most likely be poor general performance or physical damage to the board.

The tools necessary will be a Phillips Head #0 (PH0) screwdriver, a Phillips Head #1 (PH1) screwdriver, an iFixit opening tool, a spudger, and tweezers.

It is important to note the prerequisite guide, the HP EliteBook 840 Aero G8 Speakers Replacement Guide. The speaker system must be removed to begin this replacement.
