X250 Main board Replacement

#1 Post by fleamourian » Sun Jul 28, 2024 10:27 am

As per HMM states, only a Lenovo technician can change serial numbers & the boards unique identifier. Should I give up now? I blew backlight fuse on original board by not disabling internal battery before opening her up.

This HMD program will do it also.

Thx! That gives hope. Something to research. Replaced board on T21 & X200, they more complicated these days.

DOS or FreeDOS & this executable on a pen drive suffice? There is mention in HMM of all devices having unique codes. Is setting MB ID enough to boot? & how to handle connection of internal battery without frying the backlight fuse or Reading The Friendly Manual?

Most important is a proper MTM or TYPE, S/N is basically irrelevant.
Make sure to type in the fields properly, as shown in that program, no false space or dash.
