This is my 5th startup problem, BUT, those I was able to use the One Key Recovery to fix it. This time though it won't get to loading past the initial Lenovo symbol before showing a black screen with an underscore and then I won't let me turn it off or use one key recovery.
VERY IMPORTANT NOTE: I NEVER< EVER DROPPED IT AND NO SHOCKWAVES Occurred IN IT IN THE TOTAL OF 5 YEARS OF HAVING IT!
