Chromebook won't boot, unless plugged in

[SWATermelon]

So, my  2014 model Toshiba Chromebook 2 won't turn on, even with a full battery. I know it won't boot (and not just not activate screen) as the USB ports don't power devices. When it is plugged in, however, it boots fine with no hitches whatsoever.

 

My current theory is the battery is dislodged from the connector or has malfunctioned (Some of my previous Windows laptops would function fine with no battery, as long as it was plugged into the wall).

 

I would appreciate advice as to what to do and how to find out what model this is. I am fairly comfortable with opening it and doing some laptop surgery, but this will be my first time.

 

I did a Crosh (chrome's shell environment terminal) battery test. The output: 

crosh> battery_test 
No test length specified. Defaulting to 300 seconds.
Battery is charging or full (100.00% left)
Battery health: 81.42%
Please make sure the power supply is unplugged and retry the test.

 

But if I unplug the laptop, it won't boot

Like a Laptop. No strange odors or glaring warm spots.

I have had the same problem with a windows ultrabook. I suggest opening it up and checking the battery connector is, well, connected. If it is, the battery could be faulty. When opening it, I suggest doing so in a room without carpet, and make sure you use an ESD wristband or ground yourself first.

What happens when you unplug the laptop while it's turned on and running?

dims, battery icon goes red, and turns off. This takes about 3/4 a second. When I turn it back on, chrome browser says:

so then your battery is shot / worn out / defective. batteries only last so long before they won't hold a charge anymore. because it doesn't die instantaneously, and instead the icon goes red, then turns off, the battery is still hooked up, but dead.

 

because of the low cost of chromebooks, its not even worth replacing the battery in them anyway, so i'd just buy a new chromebook and use this as an always plugged in web browsing device at home or in the garage or something.
