If you find that the keyboard on your Acer Aspire One 751 has become unresponsive or some of the keys are damaged, it is probably a good time to replace the keyboard. The good news is that the keyboard is fairly easy to replace on this model, as it requires very little disassembly. Before you begin, make sure you have a suitable replacement part. Use an online parts locator tool to find the exact replacement keyboard for your model. Follow the instructions below to perform the replacement yourself.

1. Before beginning any laptop repair, it is important that you power down the system and unplug all cables, including the power cable. Then remove the battery as well. This will protect you against the risk of electric shock and also protect your laptop from potential damage.

2. Open the laptop’s lid as far as it will go. Use a plastic tool such as a guitar pick to unlock the four latches located at the top edge of the keyboard by pressing down with the plastic tool or pick. The latches are above the F1, F6, F11, and End keys.

3. Gently lift the keyboard up just enough to gain access to the ribbon cable connector underneath. Pull up gently on the connector to disconnect it and remove the keyboard completely.

4. Connect the new keyboard to the connector in the same manner and snap the connector down in place.

5. Flip the keyboard down into place until it snaps into the latches you previously unlocked. Make sure it is secure.

At this point you can replace the battery and power cable and power up the system. Check to make sure that your new keyboard is functioning properly. If so, you have successfully repaired your laptop. Enjoy your new fully-functioning keyboard.
