Y50-70 65W charger not working/recognized!

Greetings,

 

I have an original 135W, 20V, 6,75A rated charger (ADL135NDC3A) for my Y50-70 and it is working just fine! But since it's extremely bulky and inconventient I tried charging with a more compact and mobile 65W, 20V, 3,25A rated charger (ADLX65NC3A) but it doesn't work!

By doesn't work I mean it's not recognized at all, no compaibility/error messages, nothing ... like it's not plugged at all!

135W works as it should. Both have identical connector and I measure cca. 20V across both. So it must be some nasty electronics internally that is preventing charging, beacuse physically there are no obstacles for charging, except lower charging rate (power/current), but still, it should be plug & play!

Anyone had similar isues? Is there a fix for it?

Thanks,

-L

There is no fix.  It's good the power circuitry is smart enough not to overdraw the capacity of the small adapter causing it to overheat or damaging the computer

Same way circuitry should be smart enough to recognize it and simply limit the current to charger rated current. Obviously not the smartest one...
