Code malfunctioning via laptop but not via PC

Hi everyone I made a program that i upload on Nano via PC and it runs as it should but when i upload the program via laptop it malfunctions. The program doesn't behave the way it should. I have tried this via two laptops and i get same result but when i upload it via my desktop it works perfectly. I believe i have installed the required drivers correctly for ch340 on both laptops (one is windows 7 and another is windows 10) but the result is same on both. Weird it is! All suggestions are welcome. Thank you in advance

Please provide a detailed description of the malfunction.

Please post the full sketch.

Problem was i forgot to update the config.h file in library. Had to change the number of TLC chips being daisy chained. Solved!
