The keyboard on my laptop suddenly started typing "t5" for "t" or "y6" for "y". Sometimes it just drops the t and y and only types 5 or 6. No other keys are doing this. Was working on a project when it just started. No food or drink nearby (so no spills). Any thoughts on it? Thank you

Makes sure your num lock is turned OFF for starters.

If I doesn't work you can maybe get one pretty cheap
