Introduction

This guide describes the removal of the motherboard from the Nook BNRV300 device. This device is also called the “Nook Simple Touch.”

Removing the motherboard allows access to the display and the plastic front cover frame. Removal of the motherboard also enables you to work on electrical components.

Warning: Using metal tools on the motherboard or any electrical components could cause shock to yourself and/or your device. Using plastic tools reduces this risk, but pay attention when working on your device.

Tools

Step 1

Power off your Nook before working on your device. Hold the power button for about 5 seconds and select the “Power Off” option.
Turn the Nook over to find the power button along the back upper edge.
Wedge the spudger between the top of the power button and the upper edge of the device.
Push the tool down to pry the button up and off.

You should pull up from the bottom of the button. It will hing up and pop off easier and less chance of breaking the button. There is a hing on the top side of the button to pivot down to the bottom where the button is. The clips are near the bottom of the button. You are more likely to break the pivot pins doing it from the top.

Step 2

Using your fingers, take off the power button.

Step 3

Peel off the white sticker that is covering the screw head.
Remove the one 2mm-long screw using a size T5 Torx screwdriver.

Step 4

Slide the back cover down towards the USB port to release it. The pictures show the case being pried open but this should not be necessary.

There is no need to pry the cover off. Just slide the back cover down toward the USB port.

This right here! It requires little to no force to do this. You are more likely to break the clips if you force it open.

Oh man, this is absolutely right! Sliding it down away from the power button is so easy. I'm sad I didn't see this comment until after I had pried it off. I couldn't figure out how to put it back on after changing the battery, but sliding it back up is easy. iFixit should definitely update the instructions to clarify this.

Looks like they updated the instructions! Although they said “prised” instead of pried. :(

Step 5

Use a spudger or your fingers to gently pry the connector out of the white socket.
The back cover is now fully detached.

Step 6

Use tweezers to remove the brass-colored threaded fastener from the Nook plastic casing.

There’s absolutely no reason to do this. This part of the device is never touched again for the rest of the guide.

Step 7

Use an anti-static mat to prevent electric shock from damaging the motherboard and its components. Be careful when using metal tools on your device.
Using a T5 Torx screwdriver, remove the eleven 3mm screws.

Step 8

Place the spudger through the loop of the display cable. Lift the tool up, which will unhook the display cable.
Do not put force on the motherboard with the spudger. This could damage components on the motherboard.
Using your fingers, lift up the display cable.

Step 9

Using your fingers, gently lift the motherboard from the display.

Conclusion

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