I went to plug the AC adapter in my M1330 and it turned off, while the adapter's light turned off. I found out that motherboard shorted somewhere. Dell wants to charge $500 to replace it. I'm thinking of getting a new motherboard myself, but this seems like a common problem with M1330 motherboards. Many "experts" on eBay offer to fix this problem. I'm wondering if they just replace a part on the motherboard, and what that is, because if repairing it just means replacing an easily available part, I can do that. Does anyone know if I can do that?
Just had the same problem with my M1330 - after pulling it apart and checking with a lab supply and our thermal imaging camera from work I traced the problem to cracked and shorted Ceramic cap C10. It's located near the connector for the battery charger board. Replaced it with another 10uF cap and it's all up and running again
