Hi @marshwaha here, I made a recent edit to this guide for the on/off switch, I added a link to the part and the part number along with a description of said part. Hope you see this comment. Thanks, @marshwaha

My biggest issue is apparently one of the screws came loose and fell out and now won't tighten at all...UGH!

The only thing you should mention is the size of the screw head, that would be helpful.

Hi Sarki, I think I may have found the solution to your bluetooth device not working. Read this article here’s the link:https://blog.macsales.com/46143-macos-10.... You have to delete the Bluetooth P-list heres the steps:To delete the Bluetooth plist file, follow these steps:

Open a Finder window, and browse to /Library/Preferences.

Locate the file named: com.apple.Bluetooth.plist.

Select the com.apple.Bluetooth.plist file and drag it to the trash.

Empty the trash.

The com.apple.Bluetooth.plist file will be recreated.

Go ahead and try using or connecting a Bluetooth device

I really hope that helps! If you have more trouble be sure to let us know and if you have sucess.

Can The RAM in this machine run with anything more then just 2GB's? I am just wondering.

You can save a lot of weight if lets say your installing a solid state drive or putting in a second hard drive but if you know that you use the CD/DVD disc drive a lot then you might just want to leave the drive alone.

So what if the HDMI port is broken? Would the mother board have to be replaced?
