Hi Pamela,I know that a lot of people wanted an on off switch, but, I am glad to hear that won't eliminate the lock feature. I hope that the battery of whatever type, will be affordable enough that a user can afford more than 1. I travel a lot where I don't have electricity and carry an additional charged battery for my laptop. Even though that creates an additional cost, I don't use the laptop nearly as much as I use the Book Port. Fortunately, since I have only had minor problems with my Book Port in the more than 3 years since I bought it, I should be able to use it for some time to come.Your help a while back solved my problem and I thank you. Make it a great daySharon
