Touchpad no longer working

Topic

I hope this is the right place for this question. I have an older Toshiba laptop with a touchpad (alps pointing device is the driver name). I’ve had it docked for a few months and been using an external mouse. Now I want to take it on the road and the touchpad doesn’t work. Zero response from touchpad or buttons. The driver is up to date (so I’ve been informed by Windows) and installed and working OK. Looking at Device Manager it says the driver is connected to a PS2 port. Huh? There’s no PS2 port on this laptop. There’s no sign of the driver in my startup programs so I’m guessing a Windows update has done this. I have no idea which one. (Win 10, 21H2).

Any ideas?

The Device Manager is right. The PS/2 port is an internal port. There is no physical connector… the touchpad is wired directly to the chip (southbridge, most likely). This was usually how touchpads were set up on older laptops prior to the Microsoft “Precision” touchpad specification (which uses the I2C bus). If there are any modern laptops that do not have precision touchpads, they would also be PS/2 devices.

Some precision touchpads can also be set to use legacy PS/2 mode, either in the UEFI/”BIOS” or in the OS).

Using Device Manager, I uninstalled the touchpad driver. Then rebooted. Then, again using Device Manager, I installed the touchpad device driver. I was given the option of 2 drivers, one about 3 versions newer than the original. So I installed that, rebooted and … yep. It worked. If an update downloaded a new driver because an old one was incompatible with the updated version of Win10, why the @#%& didn’t it install it?

Anyhow … problem solved.
