Acer Aspire R7-570 Keyboard Replacement Guide

I decided to write my first repair guide as I found that there were no other tutorials for this on the web, excepting this write up

While I found it very helpful, some misunderstanding almost led me to break the replacement keyboard. 

Note that the order in which I removed parts may not be optimal, and that while some can be removed in any order, others cannot.

Disclaimer: Attempt this repair at your own risk. I am not responsible for your actions.

You'll need a T9 torx screwdriver and a regular Phillips. Below is what I worked with.

Follow this guide to remove the back cover. 

Part 1: Removing the Motherboard

After removing the back cover, remove the battery connector and take out the battery. 

1. Remove the screws holding the HDD to the motherboard. Lift up the silver flap on the right and pull left to disconnect.

2. Remove the tape covering the left speaker connector.

3. Remove the left speaker connector and screws. 

4. Remove the connector and screws from the right speaker. 

5. Remove the left port module and bottom LED module ribbon connectors and screws. 

6. Remove the connector under the yellow tape and set the cable off to the side. 
(can be done later) 

7. Detach the WiFi connectors and remove the single screw. 

8. Remove the two display connectors. 

9. Remove the screws connecting the heat sink. Replacing the thermal paste under the heat sink is your call.

10. Remove the screws connecting the fan and the fan connector. Also detach the blue ribbon cable.
Do not remove the fan. 

11. Remove the top left module connector. 

12. Remove the keyboard connectors.

13. Remove the 3 (or more) screws holding down the motherboard. 
(Note the Wi-Fi module should already be removed)

14. Shift the fan to the left as shown to uncover the motherboard. 

15. The mobo should now be ready for removal excepting a single connector on the bottom side. 
I did not remove this connector, I just moved the mobo out of the way of the keyboard. 

Part 2: Removing the Keyboard

I believe there are around 50 screws to be removed here. 
I would take note of the locations of the screws you remove. 
(I drew circles on paper and set them inside the circles)

1. Remove the screws holding down the right shield. 

2. Remove the screws holding down the left shield. 

3. Remove the microphone with the help of a flathead as shown.

4. Remove the screws holding down the center shield. 

5. Remove all screws in center and carefully lift the black ribbon cable. 

7. Lift the keyboard as shown.

DO NOT remove the clear plastic from the black as I halfway did (luckily without damaging anything), misunderstanding the original write up linked at the top. 


8. Remove all screws around the edges. 

9. Remove all remaining center screws and make note of their locations. (I used a sharpie)

After removing all screws the keyboard can be removed.
These steps can be repeated in reverse order to rebuild the machine. 

Here is a clearer shot of where the center screws go on the replacement board. 


All parts dismantled: 

All back together!
