HP laptop keyboard. Some keys not working as expected.
HP 8470w. Keyboard key "k" not responding. SHIFT keys producing "z" and "q", respectively. After problem arose, BIOS has been updated, but did not solve the problem. External USB keyboard works.
Это хороший вопрос?

No liquid spilling on keyboard, and the laptop has not been dropped. However, I should mention that Windows 10 crashed (possibly because the harddisk was full during a software update) about a year ago, and the laptop has been without power for almost a year. Soon after the crash I was able to boot a Linux OS from DVD, and did not notice a keyboard problem. It was after a year without power that I discovered the keyboard problem during reinstall of Windows 10. The keyboard problem now also exists when booting the same Linux OS which worked a year ago. So I thought some BIOS/firmware data might have become corrupt during power down, and updated the BIOS. It should also be mentioned that the harddisk has been taken out a couple of times, so, a possibility could be that some mechanical stress has loosened keyboard wire connectors, although I cannot see how that is likely to happen, considering the location of those wires.
