I’m trying to set up my 7040U board from my 13" using the cooler master case. I had to order the extra 3v battery, which the case page didn’t say anything about. There were no instructions with it, or anywhere on the website, so I connected it the only way it fit. The computer worked, then I mounted it and now it won’t boot. I get a blue and green light next to the connected power cable. When I press the power button the fan spins for a few seconds then nothing happens. I tried swapping back to my laptop battery and I get orange and yellow lights instead of the green and blue and nothing happens when I press the power button.
