As motherboard on my Thinkpad T540p got damaged, just recently I replaced it with thirdparty MB. My original Model No was 20BFS10L00 The replaced Model no showing as 20BECT01WW.
Now the 6 Color-sensor/ system indicator (small Red led light) on Thinkpad emblem on front panel and near keyboard are not glowing. Can some one elaborate the reasons and help me in fixing it?
Thankuou in advance.
