My trackpad occasionally will just stop working. The buttons become unresponsive as well as the trackpad itself. Only way to temporarily fix it is to reboot. I and many others had this issue on Windows 8.1 but it seemed fixed after updating to the A03 bios. Now, on Windows 10 using the A05 bios, the issue is back. Is anyone else having this problem?
I also had some issues, the it was unstable and then after some windows updates it failed to boot. I decided to roll back and will be waiting on the upgrade. Looks like other Inspiron 7548 users are having issues
I too have been experiencing the erratic trackpad. I thought for sure that disabling the default windows driver fixed my problem but after a recent update is when the problems started reoccurring. Now I have the Etdware trackpad driver disabled. We'll see. It seems to me that the problem is random.
UPGRADE TO WINDOWS 10 VERSION 1511. Or the newest version that is available to you. I've not experienced any spottiness or problems since the update. The trackpad has been feeling really nice. Like how it should.
The trackpad is still not fixed for me. I'm beginning to think the problem is both hardware related and software related. Below are my findings.
I've had two different Inspiron 7548 laptops, each with identical trackpad issues. On both of those systems, I've had the trackpads replaced so in total, I have had four trackpads, each with the same problem. In addition to the trackpad(s) failing, I've had the motherboard fail and GPU fan fail. I really hate this laptop.
Insight to the issue:
For fun, I decided to boot Ubuntu from an external drive to examine how Linux drivers handle the trackpad. The trackpad worked flawlessly for a few minutes but then started spazzing out and moving around uncontrollably. This indicates there is a serious design flaw with the hardware, not software.

Although the issues manifest themselves in different ways across operating systems, the fact that issues are both present in Windows and Ubuntu indicates the trackpad is plagued by a hardware problem. At this point, I do not know what to do. Dell cannot fix the laptop; they have tried everything. Dell won't give me my money back. I can't sell a defective laptop. The only other option is to take Dell to a small claims court, which I intend to do sometime in the future.
I will never buy a Dell product again.
