Hi, all of a sudden today some of my gestures stopped working. specific ones like swiping between desktops and mission control stopped working. I tried to go to mission control by doing a spotlight search for mission control and going directly to the app, but that didn't work either. It seems that mission control has just crashed completely. I am going to try restart my laptop now, so I will update this if it works :D thanks guys!

Try to unplug your adaptor (using battery state), if your fingerprint work good, it's mean that the problem is your electrity (in your house/office) have grounding problem. Try using shoes or something like that so your body don't make a direct contact /w ground. I dunno, how this problem could be like this, but my tips is work well.
SOURCE: Antivirus suddenly stopped Working
Download Malwarebyte's Anti-Malware, Ad-aware and Spybot, and run them all (one after another, not all at the same time) to see if you're not infected by some spyware.
Also run some anti-virus, like Avira - or even the online Trendmicro housecall (http://housecall.trendmicro.com/housecall/) to check for viruses.
And do that if possible disconnected from the internet.
If nothing is picked up by those programs, then you can try a system restore to a point where everything worked. Be sure to backup your data first, since you can loose some data with System Restore.

This could be a backlight issue, a board issue or an inverter issue. Look at the screen closely, if there is a faint image it's either a backlight issue or inverter issue. To weed out between the two you can just order on inverter, they're 20 bucks on ebay, if that doesn't work, replace the backlight. Backlight repairs are somewhat difficult. As much as I would like to be able to tell you a quickfix that will solve backlight the problem, you'll most likely have to google for guides that show you exactly how to replace the backlight or bring it in for repairs.I work for Mac Repair NYC and i have to fix this problem a lot.
