Einleitung

This guide will cover the replacement of the motherboard for the Dell Latitude E7470 laptop. The motherboard is the core of the system and as such can be the cause of a variety of issues; replacement could be the solution to a number of problems with a computer. Note that this replacement will require almost full disassembly of the laptop excluding the monitor so take care in sorting your parts and follow all steps carefully.

    • Remove the eight 4 mm screws on the back cover using a Phillips #0 screwdriver.

    After unscrewing the 8 screws, they stay on the back cover.

    • Use the pull tab on the battery connector to lift the connector straight up off its socket on the motherboard, disconnecting it.

    Personally, I would remove the battery as the first stage battery should be disconnected before any work is completed.

    • Remove the single 4 mm Phillips screw securing the bottom left corner of the battery.

    • If you are removing an extended capacity battery, remove the Phillips screw securing the bottom right corner of the battery.

    My laptop had 2 screws holding the battery. I am not sure why. It may be useful to check whether yours has 2 as well. Unlike the laptop’s back cover, after unscrewing the screws on the battery, you have to remove the screws.
