    Laptop keyboard and touchpad randomly do not work

    Ever since I've upgraded my dad's laptop to Windows 10, the keyboard and touchpad stop working randomly, and would work only after I restart the computer. (logging off, switch user, standby mode doesn't resolve it.)
    There is no pattern to it. Sometimes it would be ok for a few days, sometimes it would happen again after a few hours. I mostly do internet browsing on the laptop.

    When the problem occurred:
    - The keyboard AND the touchpad would both stop working at the same time.
    - USB mouse still works. (I do not have an external keyboard to test)
    - The lights on the keys themselves (eg caps lock, wifi) would still remain on if they're activated but cannot be toggled on/off as usual.
    - The device manager still showed no problems with the mouse or keyboard.

    Things I've tried:
    - sfc /scannow
    - disabled sticky keys
    - used the generic drivers for keyboard and touchpad
    - reinstalled the drivers for keyboard and touchpad
    - updated to the latest synaptics driver
    - made a new synaptics trackpad profile
    - disabled touchpad when using the USB mouse

    Laptop stats:
    HP Pavillion dm1-4002AU
    Windows 10 Home 64bit (upgraded from Win7 and then reset to a fresh state)
    AMD Radeon HD 6230 Graphics
    6GB RAM
    Synaptics Driver Version: 06Jul15
    Synaptics PS/2 Port TouchPad
    Lenovo ThinkPad PS/2 keyboard

    This is very exasperating. I would appreciate some help in stopping this problem permanently, thanks.

    Been there, done that, and in every case in my personal experience (Lenovo and Dell tablets and notebooks) the Synaptics driver was the problem. I notice that the generic Synaptics drivers on their download page are up to version Have you tried one of these (you probably need the SMBus version)?
