My Asprie 5 (NX.HMPEU.005) laptop came without an OS - not even a recovery partition, just an empty SSD. I proceeded to install Windows 10 booting from a USB drive. First problems started when Windows did not recognize the touchpad, and during installation also the WiFi. I had to resort to using a cable to connect to the internet for the install process.
Once Windows was up and running the Wifi issue was automatically fixed, but the touchpad still did not work.
I finally managed to fix the touchpad issue by:
1) installing the Serial IO Driver (30.100.1915.1) from https://www.acer.com/ac/en/US/content/support-product/8007?b=1&pn=NX.HMPEU.005
2) setting the Fn button to “Function key” in BIOS, and
3) pressing Fn+F7 to enable the touchpad in windows.
I needed all 3 steps to make it work, simply doing 2&3 did not resolve the issue.
As an additional problem, when I woke the laptop from sleep, it would always wake into a BSOD. I finally managed to fix the issue by installing the Intel® Rapid Storage Technology (Intel® RST) Driver (17.8.0.1065) from here: https://downloadcenter.intel.com/download/29339/Intel-Rapid-Storage-Technology-Intel-RST-User-Interface-and-Driver?product=55005 as well as installing the other utilities on this page SetupRST.exe and SetupOptaneMemory.exe. Note that the IRST driver on the Intel page is a newer version compared to the one provided by Acer on the link under 1) above.
I am not sure if it also contributed to the solution or not, but in an earlier attempt to fix the sleep/wake/BSOD problem, I also installed DriverBooster Free from Iobit, which updated 12 drivers on the laptop including the Intel VGA and NVIDIA drivers. This alone however did not do the trick, only once the IRST driver was updated did the wake BSOD problem go away.
Hope this summary will help others facing the same issue.
