Inspiron 1520 TouchPad Troubles :\ Please Help!
I have an Inspiron 1520 with Vista Home Premium. I know this sounds crazy, but if my laptop is left on for more than 5 hours my touchpad goes beserk! I have minimal control over it, and when I try to close out of different windows it will get stuck between minimizing & maximizing them. If i minimize a window and try to bring it back up from the task bar, it will get stuck trying to do both maximize & minimize intermittenly. Does anyone know of a possible solution for this? Or should I just contact Dell and have the laptop replaced. I have owned it for about 3 weeks now.
Thanks for any help you might provide,
Rick

Chignik,
This issue is specific to the Inspiron 1520 and Vostro 1500. It has something to do with the specific AC adapter rev on some of those systems. Your issue is unrelated, and should be raised on a new thread.
To all on this thread,
I need to ask a favor of you all. If I or tech support have replaced your AC adapter, could you please send me a Private Message with your service tag? I have been asked to provide service tags of affected systems wherein the AC adapter has been replaced. I apologize for not maintaining the records upon dispatching the parts, but I did not forsee a need to do so at the time. My mindset was to just get the parts out and resolve your issue. Apologies for any inconvenience, and thank you in advance for your PM's.

I'll give it a few days before I send the old one back.

Hi Bill,
I have a brand new Inspiron 1520 that is exibiting this problem, and from reading other posts in the thread I'd like to try a new power supply.
FYI, I was able to get my cursor to stop behaving erratically by uninstalling the Dell Touchpad application and installing the driver from synaptics web site all in safe mode.
This didnt COMPLETELY solve the problem. I still had to do a lot configuration adjustments. I've now had the machine running 24/7 for almost a week, switching between battery and power supply, and it seems to be working okay (not perfectly... the cursor will still jump, just rarely now where it was almost constant before).
I'm really hoping this will take care of the problem because for one otherwise this has been the machine of my dreams (the Nividia graphics are GREAT for work.... like having two monitors), and of course I was pretty exasperated and disappointed when after setting the machine up the pointer kept jumping all over the place.

If you want some fun, trying playing chess with an erratic pointer.
Good times....

Unfortunately it looks like I also have the floating pointer problem on my brand new Inspiron 1525. The label on the power adapter reads: CN-0YT886-73245-7CH-3479
REV A00
I tried adjusting the touchpad sensitivity, but that didn't help at all. A couple days ago I downloaded and installed the ALPS Pointing Device Driver (whatever that is) from the Dell Updates page, but it doesn't seem to have helped much. I haven't been able to determine exactly what triggers this weird jumping and floating behavior with my pointer -- it isn't happening all the time although when it does happen, it is maddening. I almost alway use my laptop with the power supply plugged in.
To test what is going awry, Bill B. has suggested that I try running my 1525 just on battery which I'm doing right now (at 82%) with no problem. Then I will try running it with the power adapter plugged in and presumably recharging. Finally I will remove the battery and just run it on the adapter -- a challenge as I have never removed a laptop battery before! I'll keep you all posted on the outcome of my experiments.
Is anyone else having this problem with the Inspiron 1525?

Okay, everyone, here's my report:
My Inspiron 1525's touchpad/pointer worked fine on battery with the AC adapter unplugged. I let the battery run down to 77%. Immediately after plugging in the AC adapter, the pointer started jumping around, and about five minutes later, the pointer started floating.
I sucessfully removed the battery (a cinch --easier than removing a flashlight battery) and am currently running the laptop without a battery. I had one short instance of the jumping pointer a little while ago when one of those flashy video banner ads appeared on the local newspaper's website at the same time as one of the people on my buddylist signed in or out (I could tell by the sound effect).
Uh- Oh. I lost control of my cursor just now for a minute or so when I was editing the paragraph above.
Sooo... My Inpiron 1525's touchpad / pointer seems to work fine in battery mode, has a problem definitely when the AC power adapter is plugged in and recharging, acts out sometimes when running on AC with the battery installed (I think this happens when the computer has been running for a while), and sometimes when the battery has been removed and the computer is running from the power cord.

Didn't mean to create an impression. It's just that so far, every single replaced adapter has resolved the issue. Investigating ESD factors is up to the failure analysis guys who had me request whole unit captures- of which I was able to beg my way to 2, even with upgrades offered. Hopefully that will be enough hardware for them to do what they do. In the meantime, I am going to do what I do, and replace the part that seems to be correcting the issue on every single case reported to me here so far.
Did you try your HDD in a can? Did you get a replacement adapter and put it on top of the touchpad to test, or did you just prove one side of the theory?... Curious to know. And as far as vacuum cleaners, they are not regulated to pass any ESD testing with PC's that I have ever heard of. They are notorious for causing ESD issues and have been since the inception of the PC.

You guys should go back and read message #55 --
I am totally convinced that the TouchPad problem is a matter of its susceptability to electrical "noise", or interference. My situation (identical symptoms that everybody is reporting) was due to an old SimpleTech external hard drive in the vacinity of my wife's desktop. Someone else reported these symptoms when in the vacinity of an old vaccuum cleaner whenever it was turned on.
You people who are changing power adapters are merely changing one that generates enough interference to make a different to others that don't.
Try placing the power adapter module as far away of your computer as possible, and/or stick it in a metal cannister, and see if that makes a difference.
This is a horribly frustrating problem until a way is found to fix it -- I'm just suggesting that Dell experiment with additional shielding of the TouchPad, and not create the impression that this is due to "faulty" power adapters.

I just recevied the 65 Ac adapter and it seems to fix the problem for the time being , the only problem I face is that, my system tells me that 65 Ac adapter is being plugged , so that system would take more time charge and may run slow , I guess we just have to deal with this prompt , instead of having the curser moving drastically
I couldnt find the link ,I read that pdf file day before yesterday ,in that a engineer found out why the problem is occurring , I don’t know If I Am wrong ,but it depends on the sin wav theory (can hardly remember what he wrote )…will try to look at at again and will post that link here

Satwick,
The 65 Watt adapter was ordered by mistake. The agent who ordered just happens to be a friend of mine. I contacted him and asked him to send you a 90 Watt adapter. He's doing it right now, and you should get it Monday. In the meantime, you will be ok with the 65 Watt-er for the weekend. Just use the return label to ship it back. Sorry about that. It was human error in choosing the wrong part number.
