I was recently playing a game, the touchpad has been having no issues before this, but during the game, the touchpad randomly stopped working, I restarted my computer and it hasn't worked since. I've attempted to install the Alps multi-touchpad drivers (it isn't meant for M6500, but it is meant for windows 10), but none of my attempts at installing have been successful it seems. Pretty much every time I install it, it says the installation has failed and doesn't give me a reason. I've also attempted to install the synaptics drivers (Is meant for the M6500, isn't meant for windows 10) that initially came on the computer, this successfully installed but didn't succeed in making my touchpad work. I would attempt to auto install the drivers, but when I go to the device manager, my touchpad no longer shows up in any of the options. The computer does, however, work with a mouse, but I'd prefer to have the trackpad working.
