I have had this on an iphone 5. Apple sold me a new phone as it was not worth repairing and it was out of the 12 month warranty. Its possible to order a new part and do it yourself but unless you are totally confident and have the skills to open up your phone and reassemble it then its just not worth it.

What is the actual question?

look closely at the keys along the top of the keyboard (usually called F keys). one of them should have a tiny sun icon and the key beside it will have a larger sun icon. hold down the "Fn" key elsewhere on the keyboard while pressing the one of the sun icon keys to brighten or darken the picture. the sun icon keys may also be located on the Arrow keys (<-- --> etc.)

Could be a very easy fix....does your computer seem a little to warm when this happens? If so the fix for this could be getting a better fan.
Sometimes when laptops run too hot they have a safety that shuts it off to prevent damage from heat.
You can find laptop fans pretty cheap on some computer part sites, also making sure your laptop is free from dirt and dust helps keep the temp down.

When does it open on its own?Sometimes it is easy to be press the open button as you close it which of course opens it straight away.It can also fail to lock closed if not opened further than its initial amount that it does open.To close it after it opens you need to draw it back to rearm the mechanism.

You might try taking the battery completely out for about 60 seconds, and see if this does not reset whatever got hosed. Also, unplug any external devices (like wireless keyboard/mouse, SD card reader, ...) that may be trying to use the PCI buss, just in case something is hosed with them.

if you can plug in an external monitor and it shows on the external display then either the laptop screen is damaged or you have switched the display to external as default. If nothing shows then it may be a motherboard problem.

Check the battery. Check the power brick not connected to the docking station.
