JOcean is correct that the AC adapter itself is 220V compatible (adapter label says 100-240v).  You may need to acquire a Dell 250V power cord w cloverleaf end to plug into the adapter though if you are moving to UK. [IMAGE] Dell MGJN9     [IMAGE] Dell J663C  
How can I tell if my desktop is 220V compatible. I will be moving overseas from US.
