Introduction

Use this guide to replace a broken motherboard on your Dell Latitude E7270.

The motherboard is what links all your components together to move information around. They are susceptible to age, shortages, and physical damage. A broken motherboard may leave your computer not working at all.

Before using this guide, check out the troubleshooting page to see if your symptoms match any that represent a bad motherboard.

This replacement requires a #00 Phillips head screwdriver.

NOTE: This guide requires removal of the back panel, battery, and cooling fan. The extra prerequisite guide steps are included in this guide.

    Not all the places shown are for motherboard screws; three are for the case screws. The motherboard screws are numbered on the motherboard from 1-9. Positions 2 and 3 are under the rear metal bracket. The rear metal bracket has 2 long screws and 2 short screws on the bottom, plus the 2 long screws from the rear.
