I use two needles to straighten the pin and put it in-line with grid. However when pin is pushed back and completely deformed, it will lose spring tensioning ability required for making good contact, it is over.ASUS pulls off every 25th or so board to test for defects, so that's 24 other boards that could be faulty that won't have the fault found on the factory floor before shipping. It happens more often than you can imagine, but less than you would hope because ASUS' QA is pretty good.
I've bent pins on a board before. The only way you can do it as neatly as the one OP has is from someone using a thin object that does not touch the other pins, or a faulty socket that wasn't properly checked on the factory floor. The pin is even bent backwards, which requires some effort to do.
Re: Asus. I am sure they check every single board on the automated production line for startup. It is why LGA socket was adopted - to facilitate automated testing. What you are talking about is the manual check up. Such board has already passed automated tests (means 100% working).
