 1. Ensure that there is **no shorts** for C1 C2 C23 and that their resistance is at the MOhm level.
 2. Ensure that there are **no false shorts** between the IP2368 and Type-C pins and to GND.
 3. Ensure LEDs are oriented and colored correctly.
-4. Insert the battery with the capacitor fully discharged and ensure the red light blinks **4** times and then goes out.
-5. Insert a battery of less than **50%** capacity and apply 20V power to Type-C or C23 (**left** end is positive).
+4. When connected to a standard Type-C PD power supply and **without** battery, ensure the power supply should be around **20V** and **0.6W**.

 	1. Ensure the red light comes on quickly and without blinking.
-	2. Within 3 seconds of IC protocol negotiation, ensure the power supply should be around **0.6W**.
-	3. After 3 seconds of IC protocol negotiation, ensure the power supply should be about **24W** (12W for 5V, 9V, 12V, 15V).
-	4. After 3 seconds of IC protocol negotiation, ensure the voltage across R9 should be **10mV** (**right** end is positive).
