Hi Robert, Sorry for the very late reply - I had checked this out and the touchpad is not disabled.  It looks like some underlying API has changed in Windows 10, and now the touchpad HID (human interface device) that the driver looks for to hook on to is no longer detected by the OS, so all I get is a generic PS/2 mouse device. I have the latest chipset drivers, this is a totally fresh install (not beta - release channel) and every time Windows pushes a major update (I'm now on the April release which just came out to everyone), it reverts any changes I make (such as forcing the PS/2 mouse to be a Touchpad) back to not working and being a PS/2 mouse. I *can* get the touchpad to work if I force the PS/2 device to use the touchpad drivers (takes me extracting the drivers, telling the PS/2 mouse to use non-compatible drivers and picking the touchpad driver files to get it working), however it suffers from ghost touches, false clicks, and other annoying behaviour from time to time. This is going on for what seems like a year now - is there anything I can do to get the touchpad working properly?  This device, although out of support, is supposed to be Windows 10 compatible.  It would be nice if the touchpad worked like it used to.

I've been working on this for quite a while and can't seem to get anywhere (and I'm out of warranty). Ever since one of the fall creator updates to Windows 10 (I'm assuming 1709 - can't be certain since I was opted in to pre-release versions when I first noticed the problem), the touchpad device(s) have no longer shown up in Windows. Basically, the first update that I noticed problems was right at the same time a new touchpad driver got released via Windows update.  I applied the driver, then Windows applied the new OS and on reboot, my touchpad was nothing more than a basic 2 button mouse.  I blamed the drivers at first and tried to revert but couldn't.  After a lot of messing around, I wiped my entire OS and installed a fresh copy of that same pre-release.  After installing drivers, the touchpad was still not working. Since then I've done another full system wipe and I'm on official 1709 build which is what you get by default if you build a Windows 10 install USB (so I can't pick my version of the os).  I have grabbed the latest drivers from Dell for my laptop (chipset, etc... - all the required drivers) and installed them, but nothing seems to get the touchpad to get detected as a normal touchpad any more. The only thing I can do to get the touchpad to function beyond a standard PS/2 mouse (btw, that's what it's detected as - the SMBus and/or HID I2C device(s) don't show up under Human Interface devices at all, not even hidden) is to extract the Synaptics drivers, then using 7zip, extract the .exe bundle, navigate to the 64bit version folder and manually run the dpinst.exe program to force-install the driver files since any other way it tells me there's no need to install the drivers (since it can't detect the hardware).  I then force-convert the PS/2 mouse to Touchpad and it works - but it's jumpy and not that great (but only way to get 2finger scroll which I can't live without). I've run the hardware test, laptop is 100% fine.  I know the h/w is OK since it works on the PS/2 port.  Interesting thing is if I check System Info, under I/O and IRQ's, I can see the Synaptics SMB device entries, so I'm wondering if that means the system *kinda* sees it. There's no way I'm the only person with this problem - are there others like me out here?  Has anyone figured out how to fix the drivers to get them loaded and get the touchpad working properly?  Is there any hope at all? FYI, I've tried almost everything - if you think you have an idea, post it and I'll let you know if I did it already.

I had read that a new cable may be required as well, as the lower res doesn't require as many pins.  I was not aware of different manufacturers between models though, so that's good info to have. I wasn't counting on things to just work though - that's why I decided to ask here.  This model, Inspiron 15 3552, seems to be new enough that there's no internal pictures floating around, not to mention not many people in general decide to upgrade or even replace laptop screens and take pictures of it to go online. My hope was that someone here maybe has knowledge or pictures from the manufacturing perspective, making it a little easier to confirm if things would work or not.

I recently got a new Inspiron 15 which comes with a resolution of 1336x768.  It's not a bad resolution, though I'm coming from FHD and I have to admit that I miss the resolution. I've been looking around online and have seen a few people post about "upgrading" their displays with some success if they make sure to do their homework on what's compatible.  So, in that spirit I've been trying to do some of my own homework, though it's a bit difficult because this laptop model is relatively new and inexpensive so not likely that many will "feature" it for teardowns or experiments such as this. I've researched enough to know the CPU (SoC with graphics) will support FHD and I'm capable enough to do a full laptop teardown, change parts out and build it back up again.  What I don't know yet is if the screen from the Inspiron 15 7559 line (which is the only Inspiron 15 line that offers FHD) would fit in the 3552. My hope is that Dell wouldn't want to manufacture lots of different pieces so would make their lines similar enough that things may just plug in fine.  However, without someone at Dell or who has seen the hardware themselves to say if the mounting brackets and connector/board/etc... are similar enough that they would work I don't really want to spend $150 on a replacement screen I can't use or return. So, can anyone tell me if the construction of the mounts and position of the connectors and such for the 3552 model are the same as the 7559 model?  If there's pictures too, that would be a bonus.  I would have no problems doing a video of the upgrade if it's possible so that others can benefit from this too.
