Which screen do you have?

If you have the Samsung panel LTN140KT03401 (usually found on the T430 and T430s), see here:

Use either http://www.hwinfo.com/download32.html or http://www.cpuid.com/softwares/pc-wizard.html to determine your panel model number. If it matches the one I posted, install and use the ICC profile I posted (instructions and more info here: http://windows.microsoft.com/is-IS/windows7/Change-color-management-settings ).

If you kept original partitions from Lenovo you should have factory profile installed in the system folder. I've made clear Windows instalation so don't have one to give it's name or to check if it has LUT changing tag included.

If  you don't have access to colorimeter or spectrofotometer you should use this factory profile. There is no point to load any other i.e. one made by other user because - as you said - you could do more harm than good.

In fact the panel in T430 is realy poor in color management context: narrow native gamut - way below sRGB, native color temperature nearly 9000K - to much to correct it with LUT of graphic adapter. When I tryed to calibrate it to D65 I couldn't get satisfying contrast ratio (much below 300:1) and observed decrease of brightness.

The only way to get acceptable results is to make profile of your exact panel (to native targets) with proper calibration device. But even then changes related to viewing angles are more destructable then lack of native linearity itself.
