Hp Prime screen has interference's lines when touched with finger - COB160 - 07-10-2017 01:01 PM Hi, when I touch the screen of my Hp prime calculator in order to see calculus's history, the calculator displays horizontal lines as a interference... is it normal? Another problem I have is that when I type this integral https://www.dropbox.com/s/c14kw9gsmpltrb1/IMG_0514.GIF?dl=0 wich has simple result (displayed in the image I linked), it appears a hourglass in the place of the battery status and it happens 2 kind of things: Either the calculator restarts displaying hp logo and a big (x^2+y^2=1) expression or the calculator does not respond any more. I am now waiting for the calculator to run out of power. How can I fix these tho bugs? they happened since I bought the calculator. sorry for my English RE: Hp Prime screen has interference's lines when touched with finger - Joe Horn - 07-10-2017 06:02 PM (07-10-2017 01:01 PM)COB160 Wrote: ... the calculator does not respond any more. I am now waiting for the calculator to run out of power. No need to wait. Poke a paperclip into the reset hole in the middle of the back of the calculator.
