I'm pretty good with tech, so I took apart this dock and another dock in my house and swapped parts to narrow down the...

Hi! Based on the info you gave, your battery is either unplugged or broken and needs to replaced. Have you opened it up to fix anything recently? I would just check your connection and make sure it is unplugged in before buying a new part.

From what I can tell from the info given, your screen cables are either damaged or not fully plugged in. I would re-open it and check the cable for damage and ensure that everything is fully plugged in. If that does not fix the problem, the screen may have gotten damaged somehow during the repair.

It seems like you already know the answer, and that sounds about right. Just to be safe, I would probably check the connector and make sure it is fully plugged in, as this could also be causing the problems that you are having. I believe that should fix the problem.

It seems like your Mac may have some of the WiFi plugs not plugged in or not fully plugged in. My first step would be to open up the Mac again and unplug/replug all wires going to the WiFi chip. Looking around online, this seems to be the problem that many people have.

Interesting. I would check the manual or online to make sure that the speed/capacity of the ram is correct for the slot and mobo inside of the laptop. In the past, I have had similar problems with other computers because I went above the maximum supported ram for the computer. If that does not work/the ram is the correct spec, I would try a different stick of ram and see if that works. Your ram stick may be bad and that may be causing the computer not to boot.

It seems like one of two things happened. First things first, I would clean your charging port, just to be safe and rule it out as a problem. Then, if that does not work, I would either open it up myself, or if it is still covered under Apple Care or some warranty, take it in to Apple. Even if you don't have a warranty, Apple will still let you schedule a Genius Bar appointment for free to find out what is wrong with it, and let you know the cost to repair it/whether it is covered under a warranty.

Hey! From what I am getting from reading (and please correct me if I am wrong), this rabbit just chewed through your HDMI cable? If it is just the cable that got damaged, try replacing your HDMI cable.

If your school gave this to you as a loaner for your schoolwork, Follow Dan's suggestion and do not wipe it. However (and from reading I hope this is the answer), if you got this chromebook originally from the school and it is yours (You purchased it or got it from some friend after it has been thrown away by the school), I would suggest that you forego ChromeOS entirely and install a lightweight Linux Distro. I would be slightly concerned if a school loaned this to me, as the one I have runs quite slow, and running any apps related to school would work, just run VERY slow, and the ChromeOS install on it is MANY security updates behind.
