How do you correctly use a Lab Power Supply?
I bought this HY3010D power supply and I haven't had much success finding shorts in motherboards (laptops mainly). I solder negative to any ground in the motherboard and solder the positive in mosfet, capacitor, inductor, etc.
Most of the time only V is lit up, A is 0.00 (CC light is ON and CV light is OFF). Out of 10, only 1 motherboard had the faulted component heat up. Would appreciate any technique you guys use, thank you. |

Re: How do you correctly use a Lab Power Supply?
This is one way of doing it: Build them and verify to see if it will work for you.
