Toshiba Satellite S55t-B5335 laptop (with windows 10) and my 2, w, s, and x has stopped working time from time. There are times that it would not work unless I had push lots of pressure on to the keys. Can someone help fix it?
how old is the laptop? won't be a driver issue but the keyboard itself. had to replace a customer's keyboard after he spilt water on it & the enter buttons stopped working. replaced the keyboard working & I got paid for it.
I have a Toshiba Satellite A665-S6093 with a similar problem - a handful of keys just stopped working (but different ones from those you list). The "broken" keys are not geographically related in any way - randomly spread across the keyboard (unlike yours, 2-w-s-x, which are all in a vertical line).
I bought a new keyboard and installed it, and guess what - the exact same keys are still "broken." To me this confirms that the problem is not in the keyboard.
So keep that in mind if you think buying a new keyboard will fix it.
I ended up fixing the problem by getting a Logitech wireless keyboard. And then a new laptop.
