Powerbook 2400c/180 Fuse locations reference
Posted by: Alex on 2018-01-29 23:58:43
Hello

One of my 2400c's is experiencing GLOD so after a complete teardown all fuses were checked and continuity on those fuses exist telling me they are not the cause. In the meantime I took the opportunity to document all the fuses I could find and post images of their locations here for others to take advantage of. Please note that there are three logic board types from my research.

  1. 2400c/180 with jumper cables (forces machine to adhere to 16 bit PC card type) - from what I've read this is the most common type of 180MHz machine
  2. 2400c/180 without jumper cables (forces machine to adhere to 16 bit PC card type)
  3. 2400c/240 with cardbus (32 bit PC card natively enabled)


I hope these images help. In some case you may need to click the image to see a close up view yielding more detail. What is poorly documented here are the J connectors but that was not the main driver of this post.

That thing is RIDDLED with fuses. Almost as bad the Sony Playstations.

Hi thanks for making this post. However if it’s not the fuses, what could be the fault? Caps in power board?
