The schematic will first direct you to check the battery connector. Using a multimeter, measure the voltage at the contacts on the main board. According to repair guides, you should see a steady voltage between 3.7V and 4.2V . If this is absent or low, you know your problem is either the battery or the connection itself.
Use a digital multimeter in continuity mode to test the path from the connector pins to the small silver test points near the screen. Apply a jumper wire if a trace is broken. Issue C: Keypad Failure (Some or All Keys Not Working)
