Power Adapter for travel: Grounding
I'm looking for a power adapter than I can use in Poland (coming from India). I can't seem to find anything on how I'm supposed to handle grounded electronics (such as my laptop). Would I need to purchase a European charger (or perhaps just the cable from the power brick to plug)?
Update: I'd like to clarify that this is not a discussion on whether laptops need grounded pins. There are other appliances that use 3-pin leads, like clothing irons.
Best Answer
Your laptop is unlikely to require electrical ground. For one, it would make it difficult to operate when on batteries. Various people are disagreeing with me here, very well, the main content of my answer remains unchanged below:
Poland uses type E Euro sockets: http://www.power-plugs-sockets.com/poland/ The ground "pin" is actually part of the socket infrastructure, not on the plug. A high quality adaptor should accommodate the optional ground connection.

The adapter accommodates the 3 prongs on the grounding type plug and the two prongs on the receptacle. Adapters have either a green wire or small green metal tab that allows the adapter to be grounded. By connecting the green wire or green metal tab to the electrical system ground, the grounding path remains intact.Go Travel Grounded Plug Adapter // Earthed Surge Protector

I purchased an earthed adapter in England. I haven't found it online, but I did find some that look like it. Some of these state they are not earthed and some don't say:
