be hard to know that?
lacking 2nd pen to test., no? a new pen is $8
but why not reload the software and see ? or put in new battery.
no PC stated, i guess same name, i gather.
no OS stated, windows what? the book says
FreeDos,windows 2000 , XP or VISTA./
just a pen part number stated.
the pen has battery to run the laser tip
try to replace that?
some can be like this.
some have tiny coin cell, for sure all active probes DO.
seem the battery lasted 11 years, why expect longer?
i would not.
your HP pages are here.
HP support systems are slow today, they have problems.
I was going to RTM for you., the service guide but its stalling,.
or they are deleted the users guide as I click (odd)
what Id do first is learn to service the pen
the made vast numbers of pens and i dont see any books just on pens, other that what I put above.
