Hello friends, I am using a Lenovo Thinkpad X260 model laptop. The machine's touchpad and trackpoint stopped working after a while. Likewise, the toucpad keys do not work. Whatever I did, I could not activate it. Hardware-wise, the laptop has not seen any damage or liquid contact. I formatted. I did all updates of Windows. I downloaded driver from Lenovo Support. I did all updates via Lenovo Vantage. I did updates via Driver Booster. I downloaded hardware ID "ACPI\VEN_LEN&DEV_2014" and installed driver. It shows as Enable on BIOS. But I couldn't activate it. I also get "PS/2 Mouse No Detected" error above the Lenovo logo when the computer is turned on. How can I follow a path, I'm waiting for your help. thank you.
