post windows 10 install; touchpad doesn't work!

[Akede]

Driver status between a working and non-working laptop are the same. Interestingly, although the touchpad remained unresponsive in Windows, it still could be used to wake it up from a sleep state.

Driver status checked with "sc query type= kernel" and looking at Synaptic states.

No registry modifications helped. Now looking at it as a power status matter. There are no BIOS options for ACPI and it seems overly engrained in device manager, well beyond what it was in the days of WinXP/2K. Going to try disabling Window's ability to power down devices to save energy, as I can reproduce the issue repeatedly by closing the screen and opening it again immediately.

Updates as they come. Hoping to get this solved once and for all, and save a ton of people a lot of time. I'm absolutely sick and tired of this issue.. and it's either going to get fixed, or I'll be posting a YouTube video of how much stopping power 4 HP laptops have for a .40 hollow point round.

It seems when it fails the device gets an event in device manager of "not migrated" and of interest, is the flag within the details of "present: false":

Example of "device not migrated" resulting in touchpad failure:

Device ACPI\SYN1EFE\4&26bd7bf7&0 could not be migrated.

Last Device Instance Id: TERMINPUT_BUS\UMB\2&2C22BCC9&0&SESSION1MOUSE0
Class Guid: {4D36E96F-E325-11CE-BFC1-08002BE10318}
Location Path:
Migration Rank: 0xF000FFFFFFFFF102
Present: false
Status: 0xC0000719

After an exhaustive effort, I absolutely cannot find what the hell status 0xC0000719 indicates. A lot of people get the status for variou drivers, but there is no list of what the status codes mean. Is it a timeout? Is it a failure of specific meaning? Is it a device failure? Is it a driver failure? Who the f*** knows!

At any rate, it seems closing the screen again and re-opening works more often than not. Research into this status code is ongoing. It could be a status code coming back form the driver itself. 

Going to try wiping the driver entirely, then installing it with Windows 8 compatibility mode... as it seems pretty much anyone that gets this status code with "device not migrated" is running Windows 8.1 or Windows 10, but Windows 8 and lesser seems to have no problems.

A must is also disabling Windows 10's auto update for everything, otherwise it will keep updating the driver to the latest version from their repository: Go into Control Panel, then click Advanced System Settings. Click the Hardware tab, then click "Device Installation Settings" and select the "No" radio. Otherwise, Windows will keep overwriting your carefully selected drivers with whatever is most recent. It appears the most recent for Synaptics in Windows 10 is the most unstable.. but in every care, it's a "migration failure" coming from a sleep state/lower power mode/period of inactivity.

Hey, thank you so much for this driver! I am having the same issue (3 years later... c'mon, HP) and have been trying absolutely every proposed solution on this forum to no avail. But when I started using this driver and restarted my computer it started working again! So, thank you again for restoring both my touchpad AND my sanity
