Windows 10: The touchpad and keyboard on my HP laptop are not working.

The touchpad and keyboard on my HP laptop are not working. When I connect the mouse and keyboard externally, they work. Can anyone tell me why this is happening?

laptop keyboard and touchpad not working

Problem: computer starts up normally and goes to the password log-in screen, but nothing happens when I try to enter the password. The computer doesn't appear to see any keystrokes.
Solutions tried:

1. rebooted
2. removed and replaced main battery
3. attached USB keyboard
4. hit Enter key on startup: successful in opening the Advance Options menu, but am unable to take any of the actions because all require that I enter the laptop password
5. looked for an onscreen keyboard, but there isn't one because this isn't a touch screen computer

Why I think this is a Windows issue:

1. the computer recognizes when I hit the Enter key on startup
2. the USB keyboard doesn’t work
3. the keyboard touchpad doesn’t work, but the attached USB mouse DOES work

 

hp laptop touchpad issues

I understand the problem, some laptops have huge touchpads and also very badly placed, and to top it off don't allow for the touchpad to be disabled. I personally think that is because the laptop developers like touchpads a bit too much. These day, I wouldn't mind a laptop without touchpad. My best solution to this problem is: attach a keyboard and a mouse, that's also a better solution in general in my mind, as some laptop keyboards are not very good either, and with a separate keyboard you can choose out of all models what suits best. Know that you can also connect a keyboard and use the laptop keyboard at the same time.

 

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: 19.0.12.95 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.
