    • You will need to remove the keyboard and palmrest screws, which require the use of a Torx T8 or flathead screwdriver.

    • If your N400c or N410c still has this screw, then you must use a screwdriver of the aforementioned Torx size.

    • If you find any Philip head screws holding the keyboard and/or palmrest in place instead of the Torx ones, then the system most likely had those screws replaced at one point in time.

    • Carefully lift up the front left and right corners,

    • then you will need to use a small plastic opening tool to lift 2 clips on the front. The palmrest should flip open and rest over the keyboard.

    • If you have a N410c, skip this point and go on to the next one. If you have a N400c, disconnect the ribbon cable that connects the trackpoint to its buttons on the palmrest,

    • Lift the palmrest and then you can flip the keyboard over onto the screen, then you can see and disconnect the backup battery.

    • If you bought a pre-made backup battery, you can skip this step and "follow these steps in reverse order".

    • Otherwise, if you have a CR2016, CR2025 or similar size/thickness coin cell, then read for how easy it is to tape the contacts to your battery.

    • cut open the sleeve and carefully rip away the tabs from the old battery.

    • Hold the contacts to the battery as you tape them together.

    • Red = positive | Black = negative

    • Don't put too much tape, but wrap it tightly. Of course don't do it too tight.

Заключение

To reassemble your device, follow these instructions in reverse order.
