Anyone please if you can just measure screen size of your T91 (height x width) in cm and reply to my post.
I know that the screen size is 8.9 inch wide screen diagonal.Thats 22.6 diagonal in cm, but I need actual height x width of the screen.
I appreciate and thank in Advance.

This is where math comes in handy.
We know the diagonal length is 8.9" == 22.606 cm.
We also know the aspect ratio of the screen is 1024:600, since it has square pixels.
Let x be the width of the screen, in cm.
Let y be the height.
We know that
x/y = 1024/600
Multiply both sides by y, we get:
x = 1024/600*y
Thanks to Pythagorean theorem, we know:
width^2 + height^2 = diagonal^2
Plug in the values:
(1024/600*y)^2 + (y)^2 = (22.606 cm)^2
1024^2/600^2*y^2 + y^2 = (22.606 cm)^2
3.9127 * y^2 = (22.606 cm)^2
y = 11.428 cm
1024/600*y = 19.504 cm
Therefore a 8.9" screen with 1024:600 aspect ratio is 19.504 cm by 11.428 cm.

You are beutiful mathematic 
. But you should know that the name of screen size "8,9 inches" not mean its accurate dimension. In addition you should know that vertical range beetween pixels most likely will differ from ones on horizontal. Therefore the ratio of pixeles per side will no correspond to dimetsiones ratio. Nominate ratio something like 16:9 not give accurate dimension either.
Much easier avail oneself of official datas .
This confirmed in that you get vertical size nearly 1 mm (!!! up from official data.

I have one myself, and being located North of the boarder, I have an all centimeter ruler.
Doing these measurements from the top surface, the diagonal is 27 cm. The HxLxW is 3x22.3x16.3 centimeters.
These are the dimensions of the base (the actual computer, where the keyboard and battery, etc. are found). The screen is not as wide, about 15.3cm for that last dimension. It's a fairly small netbook (certainly smaller than the Acer Aspire One, I haven't been able to compare to other netbooks), the keyboard makes good use of its space and the screen has a reasonable boarder size (considering this boarder space includes branding, webcam, two microphones, power switch, a rotate screen button and lights. The screen boarder takes 2cm on top, 1.3cm on the side and 1.8cm on the bottom in width.
Enjoi!
