Place the bottom plate and put in the screws.

There is a final test whether you put the correct screws in the correct holes. If you look through the holes in the bottom plate you should not see any screws, if you do, you must remove the bottom again and correct your mistake.

When everything is okay, you can put all the screws in place and start working on your computer again.

Hope this was helpful. I saved my daughter a quite expensive repair by bying a keyboard on ebay from China for 30US$ and doing the repair myself.

Good luck if you are going to try this yourself. And of course during this repair you could have installed another harddisk, have replaced the screen or have installed a new battery. The guide is just as good for those purposes.
