Sometimes my keys work fine, like now. Other times, without rebooting, certain keys like the R, Y, 5, 0, do not work when I press them. Sometimes if I press the R and Y key several times, or press them hard, with greater force, the R and Y will appear. Other times, repeatedly typing the R and Y still dont get them to appear.
This problem happened, it seems, shortly after I disassembled my laptop. What would cause this problem? I think it may be one of the wiring connectors that connect the keyboard to the main unit, and not an issue with the individual keys. Should I reopen my computer, disassemble the keyboard, and reattach it, which of the 3 internal cables would affect this?
What should I try to fix this? Its very annoying having to use the “On-Screen Keyboard” to type the Y and R keys when they temporarily stop working on the keyboard.
It is not easy to give you proper answer to your question.
At first we don’t know which notebook model do you have and how old it is.
In my opinion keyboard connector has nothing to do if some keys need to be hard pressed.
To be honest I think you need new keyboard.
Only using new keyboard and test functionality you will find answer to your question.
