|You may well be correct. The information about the time you have used the laptop was not included initially. I can't assume you read the manual. You would be surprised by some of the posts here. Also have to assume you know little, unless you state, or your post indicates otherwise.|
Did the issue with the volume control start at the same time as the keyboard issue, or aren't you sure?
Has the laptop been exposed to excessive moisture recently?
I would not assume the keyboard is defective or that it is the only defective component.
I suggest you post on the Dell forum. There are generally support people that field questions there. You could also try the FAQ at their site.
