Hi! Series 9 NP900X4D Solution? I am thinking I would flip up the keys with a small screwdriver and try to clean with isopropanol. Does that sound like a good idea, or does anyone have another suggestion? I found this video that could be of use. Problem: So I flipped over a bottle of balsamic vinegar at dinner and of course it fell over the keyboard and left a healthy pool of sticky vinegar flow down into and around the Backspace and Enter keys. I shut the computer down and left it to dry for 48 hours and while several keys had become slow/gluey afterwards they worked and the computer showed no malfunction. That was four weeks ago. Now the computer still works fine but the Backspace and Enter keys are becoming more gluey and sticky than ever. To the point of almost being unusable, since they have trouble to rise after being depressed.
