got it working - put some resistor. but I think it should work without it also. Will try next time if it breaks again

thanks for replies

I'm thinking what would happen if I just connect outer shell with center pin.
In the chart I see
0 Ω = 135 W barrel

so maybe it will that it is 135W charger and it is going to work?

I wish I knew about this issue before and haven't thrown away old cable :/ where is that resistor? is it in the plug or in that thicker part which is ~20 centimeters before the plug?

does anyone know where from to get correct cable?

I have W520 and original adapter. I've changed cable for it and after some time PC started showing that adapter is not original and there is not enough power. It charges when PC is switched off. Does anyone have an idea what measures I have to check? My friend checked amperage and said it is ok ~8 o...
