That HID device is likely your touchpad. What are the Hardware IDs for that device?
Touchpad problems
- Thread starter Scanian
- Start date
That is my conclusion too, especially since the Hardware IDs are:
ACPI\_SYNA120
*_SYNA120

No, it's the DEV & VEN numbers we need to see.
OK, but the only DEV & VEN numbers showing is the parent reference, which is the serialIO driver.
PCI\VEN_8086&DEV_A368&SUBSYS_95E61558&REV_10\3&11583659&0&A8
This could also be the value you need, since it is located in the registry ACPI entry named SYNA1201 (no leading underscore) as Hardware ID.
ACPI\VEN_SYNA&DEV_1201
I don't know if this helps, but it is confusing to me. How could it possibly be a power failure when the finger print reader that is physically a part of the touchpad, works just fine?

VEN_8086&DEV_A368 is indeed the Intel serial port, but that it's not working is a problem you can't ignore - especially since the error it's reporting is a STATUS_DEVICE_POWER_FAILURE. Who knows whether this is related to your touchpad - it very well could be connected???
I think there are three possibilities here....
1. It's a BIOS issue, either a setting that's wrong or a BIOS bug.
2. It's a driver error, either in Windows or the Synaptic driver.
3. It's a hardware issue.
In the case of option 1; have you changed any BIOS settings? Have you updated the BIOS? Is there a BIOS update available for that chassis (don't install it, just check)? If you've made any BIOS changes (actually even if you haven't) I would find the 'Load Default Configuration' option in the BIOS setup and select that to be sure you're using all the defaults. Also give PCS a call, give them your current BIOS version and date and ask whether there is a BIOS update for that chassis and whether you should install it.
In the case of option 2, and assuming that you've already sorted out the BIOS issues above, I would do a fully clean reinstall of Windows, deleting existing UEFI partitions and allowing Windows Update to install all drivers and updates. Unplug all external devices before you do this and don't plug them in again until you've tested the touchpad. Once the install is complete and Windows Update finds no more updates, then test the touchpad without installing anything else or making any configuration changes. If it's still not working then I'd be pretty confident it's a hardware issue.
Option 3 is the only one left if you've already sorted options 1 & 2.....

Sounds reasonable. I only flashed the BIOS once after I got my computer, and that was with the download files I got from PCSpecialist or perhaps downloaded from Clevo for my model. The only setting i ever changed is the boot order. But I will check the version and load the default settings. There may very well be a hidden setting that has been changed for some reason.
The second option is something I really don't want to do. It takes forever. But I suppose I can put a clean install on another disk or USB stick, just to make sure it is not a hardware problem.
Thanks. I will post back when I have found time to do this.

Get Macrium Reflect Free and take an image of your system drive to external media (and make a Reflect boot drive). That will give you a quick way back to where you are now.
I fully appreciate your reluctance to reinstall but in situations like this you have little choice. You need to ensure that you have a stable and reliable OS platform and you can only do that by reinstalling.
Luckily I have a cloned drive, since I installed a new drive a few days ago, using AOMEI Backupper instead of Macrium. So there is room for not overwriting my current system. But this issue goes back a few months, so the new drive is unrelated. Like I said, as soon as I can find time to test it, I will get back to you. And thanks for the help so far.
First test didn't help. I loaded BIOS defaults and there was no change. I could note that the touchpad didn't work in the BIOS setup utility either. And when I think about it, I don't think I ever flashed the BIOS since there is no upgrade available for my model. I will attach a picture of BIOS version, even if you have no use of it, I can refer PCSpecialist support to this thread. I also found this while searching the web, pointing to a faulty power supply.

However, just to be absolutely sure, I will do a clean Windows 10 x64 install in the coming days, and post what happened.

Did you get this sorted? I bought a PCS high spec laptop about a year ago and the touchpad has always gone through periods where it was non-responsive then started working again. Regular and very frustrating but couldn’t do without it to send it back.
Bought another newer model for the office this week and couldn’t believe it had the same issue, but with the new one it was resolved by taking the protective film off the touchpad that comes on it when supplied new. The film was obvious with a blue tag to peel it up by.
Got me thinking and it turns out the older laptop has protective film too on the trackpad, but it was so well fitted and perfectly sized that I didn’t realise it was even there. So well fitted in fact that I thought I was peeling off he trackpad surface itself when after patitiently using my fingernail for a few minutes I eventually caught the edge of the film.
All seems to be good now. Feel like a right fool though.
Might help you. Might not!
