Hello,
recently I asked a technician(or whatever you call him) at my small local PC store, which he owns that store, to add another RAM stick for my Acer Aspire V nitro v7-791g. Since I couldn't be bothered with it myself, I thought it would be the best idea. So he did that and the next day I go to take my laptop back and when I get back home I notice that the touchpad/trackpad isn't working, there is no cursor on windows either. I connect my USB mouse and it seems to work, but not the touchpad, and when I disconnect the USB mouse, the cursor dissapears. I called the technician, he said that it happens a lot, I just need to enable it in control panel - mouse settings. I did everything, I searched everywhere how to, even fn+f7 or whatever which is supposed to disable and re-enable the touchpad doesn't work. In device manager only my mouse shows up, I can't find the touchepad. Installed synaptics latest drivers from their website, still nothing. No drivers, no touchpad, no cursor. Only my USB mouse seems to work. I called them two more times, but they just hung up on me. I feel like they messed up a cable or something which connects the touchepad to the motherboard, otherwise, why else would it not work? Do any of you know what could be wrong?
P.S. Sorry for my poor English skills.
