What changed since the last time you were able to use the display? My laptop was plugged to my external monitor via HDMI. And then when I plugged my laptop via AVI, that's when I noticed I can't switch back to my laptop screen. I never had the setting "Make this main display" before though, but that option is now enabled to be the external monitor, as I can't switch back.
Is it getting very hot? nope
Is it in a humid environment?
nope

It's weird how the screen name will change under Device Manager. It had always been called Vaio, now Display Flat Panel (1024x768). My real display is 1600x900...

Are you able to get to the Advanced Boot Options menu, by pressing F8 multiple times
when booting the laptop?
If so select Enable low-resolution video (680x480) then try to swith back to the laptop display
using the Windows-Key+P and selecting Computer Only.

Ok, I will try that.

Some other info I thought of, my color and everything seems to be different than before. I don't know whether it's the AVI cable but colors arn't as vibrant now on my external monitor.

Do you mean since the problem started, the colours ar less vibrant or when you started in low resolution mode?
By the way, by AVI cable you mean VGA?
