I have an Inspiron 1721 purchased in Dec. 2007. When I'm typing, the cursor will suddenly move to another place on the screen. Often, this means I start typing on top of what I have already typed. Other times, it jumps to some random spot on the screen and selects something, which then opens another window. It's infuriating. It takes a long time to type even one paragraph, like this one. This happens with either AC or battery power.
This is different from the erratic touchpad problems caused by the faulty AC adaptors, obviously. Has anyone else experienced this, and if so, please suggest a solution before I go stark raving mad!
Edited to add: I'm running Vista.
I had this problem on my Vista Inspiron 1720. It was terrible when the notebook was new last October, but I was having worse problems with my cursor inadvertently picking up chunks of open windows and moving them somewhere else on the screen or opening applications etc. I managed to improve things by tweaking the touchpad settings but I never got it right and, eventually, Dell swapped out the touchpad. The new one is much better and I don't seem to get the cursor jumps any more. It (the cursor) still occasionally seems rather unresponsive, though.
Thanks, Durdie. I've tried changing the touchpad settings and it hasn't helped. I also read an article in the Dell self-help area and I went all the recommended steps. It's just as bad as ever. Even typing this reply, my cursor has jumped back to a prior insertion point at least 5 times.
Also, I do have the problem with apps opening, apparently because the cursor has jumped there, and I've hit enter at the end of a paragraph.
I guess I'll have to contact Dell for a replacement touchpad. ARGH! I spent way too much money on this system for it to be causing me so much aggravation.
Sounds like you did get lucky! Albeit, it took six months to get the touchpad replaced. Another thing Dell said in their email to me was that when you're typing, if your hand even comes near the touchpad, it is likely to act up. I was surprised they took this position, since my dh has used Dell laptops for many years without this weird problem, and my 9 year old son has a macbook with a touchpad, which he has used for 2+ years, with no similar problem. I have observed his little hands brushing against the touchpad while he types, and he still doesn't have this aggravation.
It's very annoying and frustrating to know that it could take Dell six months to fix this problem. Tonight I am going to try out my DVD player, since I haven't done so yet. In fact, there are a lot of features I have not yet tried. Guess I'd better get busy, so I can get everything corrected at once.
Last night, I posted more comments with the intention of comparing notes with you but I included a link containing my service tag etc, so the moderators deleted it. (Sorry, Dell, I'll try not to do that again ). I'll have another go tonight.
