Thanks a lot
I tried removing the battery before and it didn't work. This time I tried your second suggestion and removed all non-essentials and powered it up. It booted with only the essentials and I plugged in one device at a time until it stopped working again. However, I now have everything plugged back in and it's working just fine again. Maybe everything just needed to be reseated?
Anyways, thanks a lot for the help!
