Hi

Just a word of warning..

""If you intend to upgrade any of your hardware, do it only after you set up your new computer. For instructions
on setting up your computer, see the Setup Instructions or Quick Setup poster or Getting to know your
computer on page 3. If you have any problems setting up your system and turning it on, immediately contact
HP support using the procedures given earlier in this chapter. This must be done first before attempting to
upgrade your system.
By breaking the security seal on the back of the computer, you confirm that the computer was working
properly before you attempted to upgrade your system. After the security seal has been broken, your
computer is then, to the extent allowed by local law, covered under the terms and conditions listed in the HP
Worldwide Limited Warranty and Technical Support.""
