While I never found it to be a problem I do read of stories like yours. As HP is the author and more of this thing any guess by me would be just that.
Ask the company that made this one.
I am looking for further information on 'HP Tuneup' and 'Healh Analysis'.
The former was run for 6 hours today without change in screen display. No indication of run time, what was going on, or the results of the 'tuneup'. Thi run time is unacceptable since it monopolizes my computer and I don't know what the beneits are.
I have beeen unable to locate further info on these topics in manual or HP website.
