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.
If a brand new system has such a problem, you should definitely contact the Dell Techies and arrange for either system repair or replacement. Do not hesitate, you have only 21 days from date of invoice to return it to Dell.
You are not alone. I have a similar setup, Inspiron 1520 w/ Vista. I have the Core 2 Duo 7500, 7200RPM drive, mid resolution LCD. See specs below in next post.
I am chatting with tech support right now about this issue. The pattern I have noticed is that it is not a problem on battery power, only on AC. Add to that while on AC, it seems almost tolerable on the lowest LCD setting and the hard drive quiet. But any brightness level up and or hard drive/CD activity it goes berserk. You can watch the misery on the synaptics touchpad indicator on the tool bar. Under constant pressure it flickers and the the left click indicator wigs out.
I think mine is headed back to Santa's workshop. Good luck.

As a futher follow up. The problem appears to be only when it is plugged in, more importantly and CHARGING. It is after being on battery for a while and I plug it back in that it occurs. If I have it fully charged on AC, no problem. If I remove the battery and keep it plugged in, no problem.
My system has some power hungry upgrades that may be why this problem hasn't been more widespread. (I am beginning to think it is a system design flaw not just my individual computer.)

I to am experiencing the same problems. At first I was having trouble finding others on the internet with this problem, but it seems to becoming more widespread. I recently bought the 1520 in December. I have only owned it for about a month. I just sent it out to the repair center and it came back to me in the same condition it left. Luckly, I downloaded the new driver that was released a day after I sent out my laptop to the repair center. I downloaded and installed it yesterday and was so excited that everything was working fine. However, after my battery died tonight I put the laptop on the charger and continued to work on my laptop, and started experiencing problems. I found this forum and it made so much sense! The night I downloaded the driver, I was using the battery all night and plugged it in before I went to bed. Again, today I used the laptop on the battery, until it died - then I began experiencing the same problems. It is a very strange problem. I'm conflicted as to call dell and order a replacement laptop. I'm afraid I'm going to experience the same problems. Right now, while the laptop is charging I have disabled "tapping" in the touchpad settings. This seems to have made the problem go away while charging. I also tested it and enabled "tapping" with the laptop using battery. Exactly as the last poster stated, it worked fine. So, I suppose I will call dell again and see what they can do. But for now, I will deal with the inconvenience of not being able to use the tap feature while charging. It seems like for the money I spent, I should be able to use ALL the features on my laptop!

Exactly as Hanna said, this is the same thing I am experiencing. The tech on the phone said they would replace the motherboard and the touchpad - but if everything else is working, maybe this is a hardware conflict type of issue...I really don't want to lose my laptop for another two weeks just to get it back and see that it's the same as the way I shipped it out. Hanna, do you know what they replaced on yours the last time you sent it in for service? At least we have 1 year warranties where we won't have to pay to repair it in case we do go that route.
I called dell last night. They updated my bios and the tech fiddled with my touchpad settings. Unfortunately, I think because he was connected remotely, the touchpad was not experiencing the same problem. The tech stated that when my laptop was sent out that they did replace the touchpad. At this point, I'm still having the same problem. When the laptop is on battery all is fine, but when I plug it in (and its charging) I have to disable the tapping function in order for it to work properly. I guess its not that big of a deal, it's just an inconvenience; especially since I spent $1500! I called the tech's manager again today and left a message as well as emailed the tech about the continuing problem. We will see if anyone responds today; if not they will be getting a call from me tomorrow. I'm just not sure what to do from here. If I ask them to replace the laptop, whats to say the new one won't have the same problem? So I'm at a loss. I could possibly be as you said a conflict between the hardware, because everything else on mine works fine.
My money is on a power problem. The fact that it only appears when the battery is charging seems to fit the bill. As I noted, the problem is present for me always when charging, but it is not as bad when the LCD is set to its dimmest setting. Also, when the hard drive light is flashing I can watch the Touchpad pressure indicator flickering in sync with the hard drive hits. I think they have a big problem on their hands. They are sending me a new one.
I guess I could be wrong about a hardware/power problem if this only occurs in Vista, anyone not using Vista having this problem?
