Download the latest driver for the touchpad device and install on your laptop. Note: If Windows didn’t find any driver, We recommend visit laptop manufacturer’s website for the latest available drivers. After that restart windows and check Touchpad started working properly.If available Windows automatically download and install them for you.I also notice that the pop-up help ion dialogue boxes vanishes within a second or so, before giving time for it to be read. And follow on-screen instructions, that automatically check for the latest available driver for the touchpad device. When trying to switch between programs using Alt-Tab the box containing the icons of running programs disappears very quickly without giving me the chance to make the switch.
Select update driver, then search automatically for updated driver software.
