I am wondering is it true that 3.17 and higher BIOSes for lenovo x200/201/s had some battery checks that made not original batteries not work. Also was it removed in later or modded revisions? Also wondering do I need SLIC version? Assuming I want to be able to install/service Windows from any media including USB sticks? Also here is my RW file, could anyone identify SLIC here: [SENDSPACE WEBSITE]/file/7s2wns
