My toshiba Satellite L755-S5166, half of the screen black. The color changes from green to purple to dark. and I'm only working on half of the screen... what is the problem and How can i fix

"The screen is a 15.6? diagonal widescreen TruBrite TFT display with a native resolution of 1366×768. This display is LED backlit and a 16:9 aspect ratio."
(Driving this display is the Mobile Intel HD graphics chip. It supports 64-1696MB of shared video memory. This is not the card to play video games with.")

restart your computer and clean out battery

For me easy;

1) The Dell Inspiron 15R i5 Notebook PC comes with an Intel i5 processor, model 2410M (2.3GigaHertz frequency rate),

It uses DDR3 at 1066MHz, (Why would you?), or DDR3 at 1333MHz, and up to 8GB's of it.

http://en.wikipedia.org/wiki/List_of_Intel_Core_i5_microprocessors#.22Sandy_Bridge.22_.2832_nm.29_3

It has Intel HD Graphics 3000 graphics built-in. (It's in the Intel Core i5 processor. It is Integrated Graphics)

Ummm, no.

2) The Toshiba Satellite L755-S5173 Notebook PC, comes with an Intel Core i5 also.

Model 2450M Intel Core i5 processor;

http://en.wikipedia.org/wiki/List_of_Intel_Core_i5_microprocessors#.22Sandy_Bridge.22_.2832_nm.29_3

It comes with an Nvidia GeForce GT525M graphics chipset.

http://en.wikipedia.org/wiki/Comparison_of_Nvidia_graphics_processing_units#GeForce_500M_.285xxM.29_series

A LOT better than the Intel HD Graphics 3000 GPU (Graphics Processing Unit), above.

From what I can see it is a graphics chipset soldered to the motherboard,

http://www.irisvista.com/tech/laptops/Toshiba-Satellite-L755-L755D-L750-L750D/dismantle-laptop-3.htm

Click on the photo in Step 27. Bottom view of motherboard.
Look at the black Fan Assembly, and the copper curved Cooling Tube.

Go over to the far left of the Cooling Tube, to the rectangular silvery shape. Has 4 black screws in it. (This metal plate sits on top of the Processor)

In-between this rectangular metal plate, and the bottom of the motherboard, is the Nvidia graphics chipset.

Square dark green shape (Circuit board), with a smaller dark square shape in it. (GPU)

Means it isn't a graphics adapter card, and therefore not upgradeable.

Uses DDR3 Sdram (SO-DIMM) 1333MHz ram memory, and up to 8GB.

3) Lenovo G470 Notebook PC has an Intel Core i5, Model 2450M also.
UP to 8GB's of DDR3 Sdram (SO-DIMM) ram memory, at 1333Megahertz, too.

Intel HD Graphics 3000 is used also. (Integrated Graphics)

Ummm, no.

My choice?
The Toshiba Satellite L755-S5173.

Better graphics.

One of the things you ALWAYS look at for a laptop, because 95 percent of the time you cannot upgrade it.

(A LOT of laptop manufacturers state - Graphics Card, when the truth is it is not a replaceable graphics adapter card, as used in a desktop computer )

This means you are stuck with the graphics of the laptop, until you obtain a better one.

Hello there,

If that purple and green that is showing on your camera is the screen cover, then we can disable that. Go to camera settings/effects/disable the screen cover. If not then go to device manager/imaging device/and uninstall the chicony driver but do not delete, then restart the NB, then try to start the camera.

Hope it works.

Try connecting to an external monitor if display screen is only showing half of my desktop, the other half goes black or flickershalf of my desktop, the other half goes black or flickers various colors then it is the video card if not....have ur display screen changed.

next to the F1 key and the windows key (2nd upper key and second to last key) are two screws, usually under some covering. unscrew and lift top edge of the keyboard towards the trackpad to lay face down. Undo the wire ribbon by lifting the grey or brown tabs and remove ribbon and keyboard. Then install the new keyboard by inserting the ribbon on the place. Lock down with the tabs and put the plastic prongs (close to the space bar) into the laptop body first, and then close keyboard onto the final position. screw back in and thats all. [email protected] for any additional questions.

press and hold fn and press f11.it sounds like you activated the sticky keys
