I just bought a used HP from Ebay for my son and it requires a password to

this problem? Thanks.

The safest approach when receiving a computer from sources unknown is
to always wipe its hard drive clean and do a new, clean installation.
A HP recovery disc for Windows XP should have accompanied the computer
along with the original documents, manuals, utility discs, and a COA
(the Certificate of Authenticity) that corresponds to the version of
Windows XP that will be restored from the recovery disc.

If any of these are missing, then the buyer is essentially on his or
her own to rebuild the system. One might want to buy a retail version
of Windows XP Home or Pro (or, alternately, a Microsoft OEM version
for PC's without an OS). This is just the start. Next, retrieve all of
the applicable driver files and utility files from HP, manuals, etc.

OTOH, if one were to successfully crack or change the password, be
forewarned that whatever malware, spyware, viruses, etc., that are
persent may be released.
