ThinkPad T400

+ + + +

+ It is believed that all T400 laptops are compatible. +

+ +

+ There are two possible flash chip sizes for the R400: 4MiB (32Mbit) or 8MiB (64Mbit). + This can be identified by the type of flash chip below the palmrest: 4MiB is SOIC-8, 8MiB + is SOIC-16. +

+ +

+ The T400 laptops come with the ME (and sometimes AMT in addition) before flashing libreboot. Libreboot disables and removes it + by using a modified descriptor: see gm45_remove_me.html (contains notes, plus + instructions) +

+ +

+ Flashing instructions can be found at ../install/index.html#flashrom +

+ +

+ Back to previous index. +

+ +

+ Thi T400 is almost identical to the X200, code-wise. See x200.html. +

+ +
