I have an old Dell Inspiron 2650 laptop. All of the sudden the keyboard no longer works. The mousepad works, but not the keyboard. This happened a few years ago, and then all of the sudden (months later) it started working again.
So, I’m back to using the remote keyboard I bought when the problem first arose.
Did I accidentally do something to shut the keyboard off? Just seems weird that it would start and stop working “spontaneously”.
Could be the connector has worked itself loose. Keyboards are not that hard to reseat. What’s the make/model? I can probably point you to a guide for removing it.
