Why is my keyboard unresponsive at times?

Hi @rbortnick ,

Have there been any liquids spilled on the keyboard?

Are some of the keys literally sticking down in the operated position or is it that it just seems that way?

If it just seems that way, connect a USB keyboard and see how it works. If it is OK then the keyboard in the laptop is faulty and needs to be replaced.

If they are sticking down it is easier and simpler to replace the keyboard than to try and fix the keys as you can cause more problems than what you had in trying to repair them.

Here is a link to a video which shows how to replace the keyboard in a Toshiba Satellite A105 laptop.

Here is a link to just one supplier of the part. It is not a recommendation to use them, it is shown to give an idea of the price. There are other suppliers online that may suit you better. Just search for Toshiba Satellite A105-S4074 keyboard part for results.

Ensure that if you do replace the keyboard that you remove the battery from the laptop before you start, to avoid adding any unnecessary extra electrical problems on top of the mechanical damage that may occur if you accidentally "slip" with a tool or implement whilst doing the repair.

Hopefully this is of some help
