Anyone know for sure what is ACPI\INT3400\2&daba3ff&2 ??

I get an event on this device, and not much info on web, don't know what to believe
if this is part of Intel DPTF, I have tried both the OEM package from website for this Acer ES1, and the later Intel package, and both produce this error among others. "The driver \Driver\WUDFRd failed to load for the device ACPI\INT3400\2&daba3ff&2."

If I can't get some help, maybe I can help someone else help me! I dug through Device manager and came up with this:
it is associated under "Intel DPTF Manager" and the last "Event" recorded therein gives this sorta ominous message:
"Driver Management concluded the process to install driver esif_manager.inf_amd64_ed40dac16896d51f\esif_manager.inf for Device Instance ID ACPI\INT3400\2&DABA3FF&2 with the following status: 0x0."

apparently it no worky....

Maybe the above will help. In your system spec it says you are running Windows 7. Maybe the Seven Forum would be a better place to ask this.

No, I do some tech work so profile is useless.... lot of systems here to work on
this is an Acer ES1 runnign Windows 10 Home X64 on Intel Pentium N3540, standard ref spec from Acer.
the larger issue is very laggy bootup which puts warnings, criticals, errors in the performance log. while not unusual for Windows 10, I'm trying to knock down all obvious/overt issues and this is one.

that thread didn't address the issue.
I have a driver, so noted in my OP. but Windows reports the error I also posted.
the guess-answer would be that Intel issues bad drivers for windows 10.
voila'

In that case use driver for Windows 8 or 7. It should work. Also don't forget that other devices depend on chipset, so update the chipset drivers as well and the problem might fix.

wish that were true.
chipset drivers are the latest. [for the record, and for others that view this - as of this date I don't see any diff in the date/ver chipset drivers that W 10 wupdate installs vs going to Intel, fetching the package, and installing the Chipset drivers].
The DPTF are separate and distinct. Different Intel package, and most of the big OEM's feel obligated to spin their own versions for a variety of reasons, one being how the DPTF components are handled in the system's specific BIOS.
Lenovo, for instance, puts a switch in BIOS to enable or disable DPTF apparently because of early problems with the facilities under windows 10 [and maybe 8.1 but I have not observed the ills under 8.1]. Yoga 2 both 11's and 'pros' suffered serious degradations when DPTF is enabled and the device drivers [Intel] "properly loaded". The 'cure', and still is as of this date, is to turn off DPTF in BIOS.
Other systems do not have this luxury.
This little Acer I'm trying to remedy is one of those.
On it, however, I can tell no performance diff from the user's perspective, with DPTF installed or uninstalled. There should be a hit to battery life but if so it is very slight
