W530 embedded controller chipset ?

[constsp]

Hello, folks !
I've been googling for type of Embedded Controller(EC) in W530 and couldn't find it.

Anybody knows what type of EC is installed in W530 ?
May be somebody made disassembly and noticed EC chipset (Renesas, Nuvoton e.t.c )?

Check also for T430, T530, X230.
For those EC changes have been made to bypass the battery check and/or replace the keyboard with a "classic" one from T420/T520/W520/X220.

Are you saying chipset in T430, T530, X230 is the same as in W530 ?
