    I did.. Installed a fresh Windows 7 from USB on a Crucial M4. Gain seems minimal, boottime (taken from eventviewer) improved 2-3 seconds. Only ill effects (sofar) seems to be the fingerprintreader. There is a workaround for this issue, posted by Lenovo and that seems to work.

    So how long does it take you to boot with UEFI vs BIOS.
    From the time you hit the power button, to the time you see your desktop and can open a program.

    These Phoenix UEFI guys show booting to the desktop in about 12 seconds.

    Can you enabled UEFI after install, or do you have to reinstall?

    What is UEFI and when was it introduced on Lenovo ... - Lenovo Community

    Hmmm, might not be worth doing a clean install for UEFI after all.

    No it won't work as it uses a different partition format (GPT) so you'll need to reinstall if you want to use UEFI mode but as others said its probably not worth the hassle to gain a few seconds off the boot time.
