Howdy . A while back I requested help when my tower did not start up after being away for a couple monts. Long story short , I was given excellent advice to pull the watch battery and put back in . I did and it worked! This time same story , I pulled battery it was dead so I replaced with new battery but this time not booting up. As I look inside the fans are spinning and all. I am noticing keyboard not lighting up .Any help would be appreciated , thank you kindly.
