Lenovo X260 keyboard issue - spacebar keystrokes sometimes missed
I'm a ThinkPad fan - I own a number of ThinkPads (an X250, X260, T450s, T460s, and a T470). I also use a ThinkPad T480 at work. Unfortunately, I have come across an issue on my X260 - it sometimes misses spacebar keystrokes. This is a very big problem for me because I type fast (around 120 words per minute). I have not experienced this issue with any of my other ThinkPads. I have firmware 1.40 installed (the latest available). I have over 400 days left on my X260's warranty. How do I send this laptop to Lenovo for repairs?
