    Hello There,I brought Drok Lm 2577 module in purpose to run my 19.5V 2A laptop from 12V battery.When I plugged it in,(Voltage set to 19.5)the laptop was switching itself every few seconds from charging/battery and so on.It means that I have not enough current flowing in?I accidentally burn out the SS36 diode on first module,then ordered a second one where I did the same.Now I have 2 modules with burn out diodes,and saw few videos how to fix it/doubling diodes=doubling current.Just wondering if it will work this way?Or its waste of my time/money and I need something different?Many Thanks
