Check if the amber charging LED turns on when it beeps, that beep indicates a power interruption and would explain the lag as the processor is throttled from 100% to 75% when the adapter fails. Check the electrical wall socket and AC plug of the power adapter, don't use an extension cord. Try another adapter.
