I went to add Ram to my Dell 7520. Two of the Ram slots are under the keyboard. I carefully watched the Youtube videos multiple times on how to install the Ram chips, Everything went well until........one of the little flex cable clips that hold the flex cable in place broke off. Not only can't I find the little piece, but after putting everything back together, the keyboard doesn't work properly. I can't find anywhere to find this little plastic thing....does this mean the whole laptop is garbage now ?
