Touchpad persistently disables itself upon wake from hibernation/sleep ever since laptop purchase

[sameershake]

If you're wondering how I've gotten to this page after reading my frustration with this touchpad, luckily, the keyboard works and so does the marvellous touchscreen. The same cannot be said for this touchpad

In order to provide full details: The product number for this laptop is 2PR66EA#ABU. I bought this laptop in December 2017 from Amazon UK as a birthday gift and I have been having one persistent issue with this laptop ever since I bought it: the keyboard and mouse seems to disable itself upon wake from from long sleep. I do not believe that the issue is caused by one main problem, but a multitude of problems. The analogy goes like whack-a-mole: you think you only need to crush one bad mole, then three others pop up out of nowhere.

I use this laptop for study. and That means writing notes for college, revising them, and sometimes taking a break.

One issue: if I closed the laptop lid(which is by default, set to "Go To Sleep" in the control panel), or pressed the power button on the side (also by default goes to sleep), upon wake, 60% of the time, the laptop would think it was in tablet mode, and the mouse/keyboard would not work (but the touchscreen did). This is not an issue that could be easily fixed by putting the laptop back to sleep again (which worked, randomly, 25% of the time) or even restarting (worked 40% of the time), restarting again (probably worked 55% of the time) and again (not much more than 60% of the time). Sometimes, the keyboard would start working again but the mouse would not. Other times, the mouse would work, but no the keyboard.

However, I found a temporary fix: upon reboot, I would go into UEFI Diagnostics tool and perform a simple hardware test for mouse/keyboard. Then I would boot. This seemed to work for a two or three weeks when I stumbled upon it while playing around with the diagnostics tool in February - albeit, 75% of the time - until it didn't, in May/June, when it almost never worked as a solution.

Around that time, I was getting fed up with Windows in general - I installed a copy of Ubuntu Linux as a dual boot solution. The components were working fine at first, then I encountered the same problem on Linux upon waking from Hibernation(or as it's called on Linux, suspend). (Most of the time it would not work on start up, showing up as a PCIE Bus error).

I found the solution to the problem: for some reason, the PCI Express power saving tools (PCI Express Active State Power Management, or PCI-E ASPM for short) got in the way and automatically enables itself on wake. On Windows, I went into Control Panel > Hardware & Sound > Power Options > Edit Power Savings > Change Advanced Power Settings > PCIE Express > Turn Active Link State Management off on both Battery & Charging. (For Linux: I tried "pcie_aspm=off" in grub configuration but that didn't help).

Windows has worked extremely well almost ever since. almost. No touchpad/keyboard lockups for the most part. Then it started happening again.

I then came across the same issue on these forums here: https://h30434.www3.hp.com/t5/Notebook-Hardware-and-Upgrade-Questions/ENVY-x360-laptop-keyboard-and-...

Most of the stuff in that link did not help except disabling the Intel Integrated Sensor Solution. Now, 99% of the time, the mouse, & keyboard, always works upon boot on Windows. In linux, I still have to tweak it a bit: sometimes if I reboot into Windows from Linux and then restart and boot into Linux, everything is fine. Rebooting Linux itself from Linux never works.

Which brings me here. Now, since last week, the touchpad almost never works from bootup no matter what I do! Even worse it doesn't even show up as a device anymore on Device Manager in Windows (for linux: it doesn't show up as an input device using the xinput command in the command line, nor is there a pci-e error upon startup anymore) .

This is quite different to every other time I've had this issue as

1) the keyboard works on windows bootup 100% of the time. It's just the touchpad.

2) Every other time I have had this issue, the touchpad would still appear as a device that was working properly in Device Manager. It does not show a touchpad at all now.

Luckily, I followed these instructions on the HP Support Forums, telling me to remove the drivers and reinstall them again: https://support.hp.com/us-en/document/c00033108. Afterwards, the touchpad showed up as a device in the device manager and worked fine.

I wouldn't be here if it was still working. As of this morning, upon boot, the touchpad has completely stopped working and again, the touchpad does not show up in Device Manager. No matter what I do. Uninstall the driver. Reinstall the driver. Boot into UEFI Diagnostics (where the mouse works), restart the computer 3 times. Hard Reset. Nothing seems to work anymore.

If someone could assist me, or if someone can tell me if this is a hardware defect that I don't know about (I am still covered by warranty for two years), please let me know. I have college starting again soon and I don't want this to happen again.
