I am writing in reference to your e-maill dated June 3, 200X.
I am sorry to say that we no longer offer the instruction manual for the computer and I am sorry that you have been having trouble with the battery only last about 45 minutes.
I am enclosing the instruction manual for the computer as well as I think that we will be able to send batteries that fit this model (1200). The battery cost $350.
Thank you for your understanding.
