Inspiron 7570 Cursor lags and completely stops working (Windows 11)

Did you check the condition of the battery when you had the system opened?  Is it perfectly flat or is it starting to swell?

Hello user_19ffd3,

I started to Google your problem, and it didn't take long to discover that you are not alone. The problems were similar while the proposed fixes were all over the laptop's hardware and software.

I very recently ran into a similar problem with a PC I recently built with an ASUS Z890 Pro Art motherboard and an Intel Ultra Series 2 i9. The reason I chose to offer the following solution, was because of the timing and the amount of time I "wasted" trying increasingly complicated fixes.

I was using a wired/wireless Logitech 903 Mouse. It had already given me BT attachment problems, and it, like your experience, began to drive me nuts with that similar lagging and stopping and starting. I swapped out different BT adapters, turned on/off settings, tried the wired version, switched to a Hero 502, updated drivers, and a whole lot more fixes, than were even remotely necessary.

I occasionally found some improvement as I continued to troubleshoot the lag, and out of the blue I decided to switch to a brand new mouse pad, and instantly the problem was solved. The lesson learned is one we have all learned before: if at all possible, steer clear of the more complicated proposed solutions; that are offered.

It could be, that you will need to rely on the in-depth solution offered by the MIT engineer, but it could also be like what I found on an obscure small forum. The owner took his laptop top off and discovered some small crumbs beneath his/her mouse pad. It was blown off with a can of air and the problem was solved. I didn’t read all of the posts, that were offered as solutions to this laptop user’s lagging, but the thread was long enough to say that this poor user was run all over repair manual. I read it, while looking for an explaination to my own lag, but didn't save it because it was for a laptop.

While you wait, try Googling your symptoms, and attempt to apply the rational suggestions and hope that you get to post your own solution. The most valued piece of information that I thought you shared, was that it came back on without any “known" help, that you provided. Did you move the laptop with enough force to create that short-term fix? Try jotting down everything that you can remember from the time the problem presented itself until it was working again, and then up to the point in time that the lagging returned. Try replicating or reversing your own observations.

Also, can you identify any other changes that also showed up that you can't remember being there before the lag showed up? Did you download or install or uninstall any software of any kind? Can you roll back any related drivers or even the BIOS. One thing that is almost certain; is that there is another user with the same experience, who has asked for help on a forum. I learned most of what I have needed from reading PC sites, PC magazines (at one time I was subscribing to five of the kind that were brought by the USPS mailman!), and forums like the DCF.

This will not be in a Dell manual and only if this works, are you allowed to mention me: Try closing the top and holding the laptop up-side-down, shake it gently, but like you are convinced that this is sound advice! On that list, try including and physical changes that your laptop was exposed to. Was it touched or used by another person? Did your dog walk on it, while it was in it's case!

I Googled back to 2021 and it brought me right back to Dell, to the link, below.

My very first DCF post was 2 decades ago, right after I had a Dell technician in my home, trying to get my first of 4 replacements, of the Dell XPS 600, to work at all. I barely knew what a hard drive looked like, when I offered technicians my assistance, which amounted to holding a part, or a wire out of his way. I was learning the names of computer component parts by asking each tech, “What is this called, and what does it do?"

You wouldn't believe how much I learned over the period of 4-5 months, and how useful that early "home-schooling" would become. I had more techs in my home, that combined, taught me how to assemble a PC! Most of the parts handed to me, were first shook by many of these techs. I never had a working XPS 600 in my home, but I did buy "up-side-down" to the XPS 700. Over a period of months, that 700 stayed inside the box, inside my garage. That story is the reason; that I am here suggesting an old "Dell Technician-Trick!"

I hope you will find the easy fix and that laptop serves you for a long, long time.

@ejn63​ I haven't had the system opened for a very long time but, the last time I had it opened was a few months back to get my battery replaced so I doubt it's the battery's issue

@XPS700GB​ My cursor started working today normally as well. Infact I'm using it right now to type this comment. I have no idea why is it doing this the touchpad is working perfectly fine but I just know its going to lag again in a few hours time and I can do nothing about it😭But I'll try holding it upside down and shaking it

@XPS700GB​ One thing is for certain, no I didn't download anything prior to this but when the cursor first glitched and lagged I had a pending Windows update so I naturally assumed its because I didn't update my laptop so I updated it but sadly that wasn't the fix. I downloaded a Dell touchpad driver as a last resort and restarted my laptop in hopes that would fix it but it didn't so I just gave up and shut down the laptop and the next day when I powered my laptop back on it started to work itself lol

@user_19ffd3​ Also I followed this post's advice as well downloading Synaptics file and what not the touchpad was driving me crazy. Here's that post:

@user_19ffd3​ 

If that was a third-party battery, they very often are of a different size by a slight amount than the OEM ones, and they can cause touchpad and keyboard issues as a result.  How does the touchpad perform with the battery removed?

Hi again,

Did you have any good news to share regarding the cursor lag symptom. I am amazed at the number of fixes offered for a problem like yours! It is almost guaranteed that someone, somewhere on a forum, has asked for help with a problem identical to yours.

This link, for Rapoo Mouse & Keyboard products, had an abundance of fixes for cursor unresponsiveness. The nice thing about a site like this, is that it reveals sources to check that one didn't know existed. The fixes applied to independent keyboards and mice, will often apply to laptop pads as well. (https://shop.rapoo.com/blogs/troubleshooting-fixes/mouse-lagging-fix). I bookmarked this link. There is a section that refers specifically to mouse pads.

I recommend that you read through the offered solutions for a poor response from mouse pads, keyboards, and mice in general. This site also covers the MANY options that can be checked in Device Manager. On my laptop I opened every item in Device Manager, related to mice, cursors, keyboards, Bluetooth, sensors, human devices. and looked at the properties of everyone. I also looked at the “Events” tab (under properties), which can provide an indication when an item became active and when it stops working. It is a tedious process. And when I had every possible one open, it was daunting to say the least. I would encourage you to rely on a reputable post like this one above, vs. a hit or miss attempt to find the right driver location.

I actually had a laptop dream related to a cursor that couldn’t be moved into a checked box, that needed to be unchecked! I don’t know why, but I woke up feeling panicked from the dream.

A couple thoughts came to mind, when I lay there awake at 3 am. The fact that your external mouse is working properly can help you remove potential reasons for your laptop’s mouse pad dilemma.

Do you experience the inability to control the precision of your cursor? That has happened to me, just like in the dream. Check all of your curser settings? Do you have a tail (trail) following your cursor? Speed settings? DPI settings can be adjusted down to see if you experience change. If not adjust back up to a higher sensitivity. Try adjusting each of the options you are given. Try a reset to the default settings.

I have experienced lag, when my system is being overtaxed, and by that, I mean; that I have too many processes running in the background.

Try determining how many processes are set to run when your computer starts up and how many are delayed start-ups? Usually, your antivirus software will have a feature to show you all of the processes that you can turn off when your laptop starts up. If you are unknowingly taxing your system, your lag symptom can be a sign of something (Performance) you'd want to take care of regardless of the lag problem. Try turning off every process or software that does not need to be running.

You can hit Control, Alt, Delete and get your Task Manager to pop up and show you all the processes that are running. (Or find it in the Start menu under Windows Tools) Check to see if you have multiple instances of a processes running? Example: if you have been online for several hours, it is very possible that you have 5 different instances of Edge/Firefox/Google (whatever you use) running at the same time. Plus, if your browser settings allow it, you could have things running that you didn’t know about. Consider running an extension like Adguard (I use a free addition.)

I have found that the only way to safeguard my Firefox default- browser choice, is to use my favorite utility software called Revo Uninstaller Pro to completely remove Microsoft’s Edge. That is not a necessary operation and it will keep forcing its way into action, which is an additional browser placing a drag on my system. Try shutting off as many safe choices that you can. Ex. If Adobe software is running in multiple applications, but you are not using any of them. Turn them off and don’t let them run at start up. Turn off your printer at startup. The number of things that are running in your background can possibly be your culprit.

Check out Revo Uninstaller Pro and their new addition, called Revo Registry Pro. It has a feature that allows you to change a whole lot of settings and get back the features of Windows 10 Pro. For example, you can move the start menu to the far left. There is a feature that turns off all Microsoft apps that are running in your background. These two utilities are put on every PC that I build for others; its that good. The registry clean is very stable and provides different levels of clean. You can try both for 30 days, and they could help you eliminate the reason for your lag.

Make sure that you aren’t running two different Antivirus applications. Even running Windows Defender with a 3rd party such as Norton, can cause mouse lag.

You had mentioned that after 4 hours, the problem would return. That was one of my 3 am thoughts about cursor lag, and performance in general. I remembered a number of times, after doing a lot of online work, on machines (that I no longer own) that were in need of more memory, had a slower mouse response. I discovered that a change in browser settings, corrected a problem that was related to the amount and kind of information being saved to my computer.

While using your laptop, if you are doing a lot of online work, try to manually delete everything that is being store in your browser. After that 4-hour time period arrives, do you notice any improvement with your cursor?

One last thing: get a cleaner, like the kind that you would use to clean your monitor screen, and spray your mouse pad and using a soft cloth and wipe it down so that is clean and smooth. Related to that, grab a can of air and with the thin attachment taped to the can, spray around the gap between your mouse pad and the laptop surface. It is possible that dust built up inside.

Let me know if you solve this problem. Thanks for the opportunity to offer some possible solutions. Hope that you are enjoying your weekend. where is home for you?
