System is very slow after changing battery
My battery life was getting shorter so I ordered a new battery and replaced it with no issues at all. Put everything back together, plugged it back in and the iOS Yosemite took a very long time to boot up. Then after booting up the top menus didn't display for several minutes. The mouse is lagging horribly and programs take forever to load. I have tried rebooting it a few times and no change. I am not sure what could be the cause of this.....any ideas?
Lastly I saw an explanation on how to reset the smc which I did, not sure whether it worked or not but no change in the slowness.
