  2. this was no help at all... my compac computer doesnt even have an enable vertical scrolling button im quite disapointed! inface ive grown to hate this stupid laptop! i will never buy anything from compac again why cant the mouse just work like normal laptops? oooh no instead the frigin thing has a mind of its own, it works when it wants to work, you could be in the middle of typeing up some important email and the mouse pad sends your curser to the middle of your message and bam! next thing you know your typing oh hey joe how ya doing, its been along time moon pies are also good with dessert wine, and thats how my cat wiskers became a i once was part of a mexican dance tribe but have sense eaten my shoes are a beautiful color....ya know what i am saying DOES ANYONE OUT THERE HEAR ME? i just cant take it anymore i wanna throw my laptop at the wall, oh wait, i already did, but it survived the impact, not a scratch on it. my replacement mouse that i had attached in the usb hole thing however..... has sense past on, into a hundred peices as i whiped it into the corner of the door frame! so....once again technology thank you very much for causing me so much grief and annoyance <<---annoyance? is this a word?

    1. I know what you mean. I actually have an "enable vertical scrolling" option. It is already clicked, yet the right side of my touch pad does not respond at all.

      To your concern about not having a "vertical scrolling" option. I thought the same thing. Ours is located in a different spot. Click the "+" next to "scrolling" and then you will see "one-finger scrolling". That is where the "enable vertical scrolling" is located. See if that helps you.

      As to the mouse having a mind of its own; yes, I have experienced the same thing. I believe that the sensitivity instructions given will help that issue though.

      I too am at the point of wanting to just buy another computer just because of the mouse issue. It has become a true annoyance. Back in the day, if I closed the entire laptop, waited for a couple of seconds, then reopened it, the touchpad would somehow "reset". This became annoying after months of doing it because it takes about 17 seconds for everything to reset again. Even that doesn't work anymore.

      To the writer/instructor of this page... thank you. Your instructions were superb, I truly believe my touchpad is defective. You showed me how to fix many other issues (i.e. the sensitivity issue to which the last writer was referring).

      To the last writer, you made me laugh out loud; I have experienced what you were talking about for several months and I have sent emails where I look like a complete numbskull :) I feel you, friend. This too may be my last compaq purchase.

      Thanks again to the author; your advice was very comprehensive.

  3. Ok, so I'm the third "anonymous" guy. I just wrote like an hour ago or so. Anyway, there is a trick that worked SOMETIMES that I was reminded of as I still researched the issue of the right side of my touchpad not working.

    If you press "fn" and "F7" and enable the "Karat Browsing", then that will work temporarily. One time, this worked for several days, while other days it did not work at all. I hope this helps. If I find something else, I will be sure to come back and report.
