Thanks for choosing FixYa and welcome to the site. To be honest, without running a diagnostic test, it is hard to tell. This is what you need to do next. Sometimes, it can be just a few things. Other times, it can fry the all the electronics. You should try to take it to the shop to have a scan done on it. They usually cost around 100 dollars. Without the test, it is like trying to find a needle in a hay stack. If you can't, all I can tell you is start testing parts and fuses. Look for any damage wires. If your computer is close to the battery, that may be what is bad. It has a metal shell. That may be the only problem but you just can't tell without the test.
