NO PC stated (wow1)
NO OS stated, XP, vista,w6/8/10? wow 2.
that is a relic PS2, mouse, nobody use those now, and PS2 parts are unique to the makers, eg: HP mouse fits only HP PC.
so.... how can I answer lacking all facts above missing.
why not buy a USB mouse and end the PS2 ERA.
end it. go to goodwill store, buy used mouse USB for $1?
next time tell what PC is there, it has name and model.
then buy real mouse. USB, not PS2.
my 2nd guess
is you do not own any such mouse,
in fact the numbers 143315-B21 , are not on the bottom of your mouse at all and posted to the wrong form.
best is to post at HP, or at least post to your PCs name and model form
mice come in many formos
- 9pin serial (super relics) D-shell shape conn.
- PS2 HP , or Compaq) green plug, year 2000 junk.
- USB (sold in all stores, even walfart has em)
- USB + wifi , wireless mice. (dead batteries?)
in each case the PC has model and so does the mouse.
only that matters first, then why it fails 2nd.
143315-B21 (this mouse is 18 years old now)
used back in the days of Compaq EN series Deskpro's 2000 year.
Pentium III era.
if that is your PC and is internet connected? are you?
that old PC has 2 USB ports, and any USB mouse works there.
and upgrade from nasty old PS2, green end plug mice.
next time post to your PCs, name (HP) and model.
here is one example of posting the EN series PC
