If you're in the market for a new power adapter for your notebook then you might want to give the NB 120 from FSP Group a look. With six different connectors, it should be good for most systems, covering, as it does many of the major models.
The NB 120 is compatible with 19v input notebooks. It's simple to use and is no bigger than most notebook power adapters so will fit inside your laptop bag easily. If you want to take your laptop overseas with you, then you'll need an adaptor as it only comes with a cable for UK use.
