3000 N100 0768B9G. Touchpad not recognized after cleaning
I had to open the laptop casing and used this to wipe the usually hidden edges of the sensitive surface of the touchpad with a damp cloth. After reassembling and starting, the touchpad seemed working as the pointer responded to the touch. I had to re-attach the keyboard. After that the touchpad was not recognized. The connection to the mainboard seems fine but I re-plugged it. If relevant or not (assuming the touchpad is responsible only for moving and clicking), if the pointer happens over a link, the URL is shown, that is the pointer is active. 1) The connection to the touchpad seems to have no plug, i.e. is soldered, and I didn't check it. Should I, even after a short intervention that I did? 2) There is a dark glossy bulging surface ca. 1x.5" on the bottom (back) of the touchpad. Just in case, should this be open or covered? 3) Should I need a replacement, how do I find compatible ones?
