Hello,

I was just wondering if anyone could help me with my confusion (I'm totally computer-parts incompetent).  

As long as I get an adapter, will I be able to use my AC adapter abroad, or do I need a transformer as well? Is my AC adapter dual voltage (I heard this allows you to use it with an adapter only).  I will be living in India for 4 months so I am just trying to make sure that my laptop will work.  I have the 65W 20V adapter.

Thank you for your help (sorry if this is a dumb question!).

Note however that you will need an adapter that converts your two-prong North American plug into the two-pin version that's used in India (and Europe.) You can buy one inexpensively at any travel accessories store. I've also seen them in dollar stores.

All the AC adapters I've ever seen for electronic devices have a sticker that indicates the acceptable input voltage and frequency. In the case of the Lenovo 20V/65W adapter the input voltage is 100 to 240 VAC and the frequency is 50 to 60 Hz.

Alternatively, you can buy a new cable, the section that goes from the AC/DC to the wall socket.

I bought one in the UK for less than 2 USD, which is cheaper than most adapter and is less bulky.

Hi,

does the following laptop has the internationally adapter? Can I used within 220V?

As far as I know all Lenovo notebook computers come with AC chargers that work on 100-240VAC. You may need an inexpensive mechanical adapter to convert from the pin configuration of your charger to the pin configuration that is used in local power outlets.
