Thank you for this guide, I’d have struggled without it.

I had a bit of a dent where my power socket was, and it snapped the surround of the screw holding it in place, a replacement is £25 on eBay.

I figured instead of paying that I’d try using a glue gun to fill the void between the socket and the plastic wall behind it.

Also bizarrely my HDD was only held in by two screws, which is a bit strange as I don’t think I’ve ever had this laptop repaired before.

Thank you very much fot this guide. It helped me a lot since after remving all screws I had no idea how to procede. Step 8 and 10 especially were helpful for me.
