Hi ,


The part numbers that you've provided is compatible with your machine and all 90 wattage. Hence, model name was used for manufacturer details and depending per region. As long as the part number is available in your region it should work in your device.

Yes the part number i stated b4 is for my region and is compatible for my laptop.


But what i trying to figure out is the model name. DC, LC and CC.

Would it have a specific model name for my laptop or region.


Right now i am using ADLX65NDC2A but i dont know if the 90w ac adapter should be ADLX90NDC2A, ADLX90NLC2A or ADLX90NCC2A

Should it be the same DC or maybe thats not availible in the 90w ac adapter or shouldnt be used with my laptop?

Lenovo Ac adapter 3 pin:


A 3 pin extension cord for a 3 pin lenovo ac adapter have to match the power cord? Which is 110V or do it have to be able to provide the lenovo ac adapter Input or Output power?
The extension cord might have to match the ac adapter power cord but sometimes the lenovo AC adapter use more power than what it state. Right?

The ac adapter need to provide 1.5A and 100-250V or 20V 4.5A for my lenovo ac adapter?

I need to buy a ac adapter to fit a 3 pin lenovo ac adapter.

Do the AC adapter(converter) need to convert the electricity for the lenovo ac adapter?
Do i need a Transformer/AC adapter(converters) or Plug adapters/travel adapters for the lenovo ac adapter?
