with reference to your inquiry, I very much regret to inform that, as HP has not yet started bundling Windows XP 64 operating system or any upgrades for it, therefore, HP cannot provide any drivers or techncial support on upgrading to Windows XP 64 Bit operating system. However, depending on the requests that we are receiving from our customers, HP may as well release the 64Bit drivers. As soon as the drivers are released, you will be notified through email. Also, I request you to keep checking the HP support and drivers page of your Notebook for the same.
However, I am providing you the web site wherein you can find the drivers. Please refer the web sites below which can provide more information and can help you.
NOTE: The URL(s) above will take you to a non HP Web site. HP does not control and is not responsible for information outside of the HP Web site.
I hope that the information provided would be helpful. Thank you once again, for using HP Total Care and giving us an opportunity to serve you through email Support. If you need any further assistance or clarifications, please do not hesitate to reply to this mail. We would be delighted to assist you.
In closing, let me add that we appreciate your business and support. I take great pleasure in helping an esteemed customer like you.
