The two shift keys on my laptop's keyboard are randomlynot registering. I have confirmed that it is an issue with the keyboard itself by 1) installing the latest drivers for the entire system, 2) ensuring I am on the latest BIOS update, 3) ensuring there is no software intercepting the keypresses, and 4) using an external keyboard to determine whether it as well had isuses, and if keys would register when I used the laptop's shift key (they did). When the keys do work, they only work for a short tine; after a random amount of keypresses, they begin to fail to register. Some keys ('j', for example) cause this to happen faster than others, and no key appears to be usable indefinitely, without causing the shift keys to fail to register. As far as I can tell, this is an issue that only extends to the two shift keys on the keyboard.
Normally I would RMA the laptop and wait for a replacement, but I'm a university student in a computer science program, and absolutely cannot go more than a day without my laptop. I can do well enough so far with my external keyboard, but I cannot use it in lectures to take notes, so it is quickly becoming an issue. Because of this, I want to try to find a fix that I can use to temporarily fix the issue until the end of the semester, after which I can RMA the system. Is there such a fix available, or am I stuck with a faulty system until mid-December?
