Dear HP,
I have spent a number of hours trying to find a replacement USB HP-5 Link (for a x4000 mouse).
I have found the manual http://h10032.www1.hp.com/ctg/Manual/c03088883.pdf which gives a bar code reference of 641900-001. However, I have run this through http://partsurfer.hp.com/search.aspx (together with all manner of other searches) but to no avail.
Please can you let me know where I can purchase one? There is nothing wrong with my mouse. I note that all major suppliers of wireless mouse/keyboards etc sell the "dongle" separately (they are on ebay).
Many thanks for your help.
Kind regards
