I browse the Internet using a USB wifi dongle and Windows and then take out the drive and use Linux for my own business. I removed the network and bluetooth cards, as well as the wireless antenna of that laptop, but I still notice that when I writing both code and on to the shell characters are miswritten or not written at all or apparently charaters get written in "temperamental" ways that hit to some "memory"/"intelligence". I also know that keyboards have internal memory chips.

How can you reset/wipe the keyboard controller? How could this be explained "technically"? What do you think might be "technically" going on?
Technically, I would think that you are experiencing either a hardware fault or a driver issue. I know that on my laptop, there is an issue wrt. some keys endlessly repeating under certain cirumstances and I have always thought it to be an issue regarding the driver rather than the BIOS' fault. I could not reproduce the issue outside Linux, but it only happens occasionally thus not sure if it is that. On desktop keyboards (mechanical ones...) I have experienced key chatter (duplicate keys when pressed once) but these were always hardware faults most likely caused by dust. That being said if somehow your BIOS or other firmware were corrputed it would be quite unlikely to be fixable for less than getting new hardware. On some (new and expensive?) Desktop systems, there are dedicated buttons to use a different BIOS located on a separate chip but I have never seen such a thing for laptops... HTH Linux-Fan
