How to enter BIOS setup in Sony Vaio SVT11125CGS

this will be helpful

so technically you use assist button when system is off...... than from rescue select the bios :-)

F2 does not work on my svt14112cxs, instead with the computer off, press the "assist" button and then select BIOS in the menu.

T series laptops have an assist button which should be pressed to get the option to Enter Setup.
