OK a couple of questions about your MBP. Go to about this Mac in the Apple Menu and take a screen shot of the window that opens. I am assuming that you have upgraded to Mavericks on an older MBP but that may not be the case. If it's new I would be taking it back to the shop. Screen shot is performed by pressing Command + Shift + 4, use the cursor to select the window while holding the left key on your mouse and release, the screen shot will be on your desktop.
