Archive for the Lenovo ThinkPad R40 in its Pentium 4 variant, as the P4 token in the name indicates, packed as RAR at 1.29 MB. No board number or revision is listed, so the exact contents remain unknown until extracted. Repair material of this kind is typically used to trace power sequencing, check rails around the CPU regulator and locate parts on the board. Make sure the processor version and the board number on your PCB correspond to the files, because mobile and desktop-class P4 builds differ in layout.
