I found instructions for taking apart an Asus L3800 or Asus L3C laptops. Apparently both models are the same or at lease very similar.
Let’s say you repaired the laptop, assembled it and now it gets power but will not turn on. What could be wrong?
1. If you removed the CPU, make sure it’s seated properly inside the socket and the socket is LOCKED.
2. Make sure the memory is properly connected to the motherboard and making good connection with the slot. Try reseating the module inside the slot.
