Hi all,
I have an N53SV which is dead. When I plug the adapter in the LED on the adapter goes off. From what I have read this is because the adapter detects a short and cuts off power. I found someone had the exact same issue and they replaced the DC board to make it work again. My concern is that if I unplug the DC board from the motherboard and plug the adapter in, the adapter led stays on, so does this mean the DC board is fine and the motherboard is at fault?
When I got the laptop someone had already looked at it, and I could see a lot of components have been resoldered, and 1 mosfet (CSD17310) had actually been soldered on the wrong way round. I have put it back the right way round and checked all other components, none of them look blown or physically damaged (or the wrong way round..)
Does any one know where I can start looking for problems on the board?
Resistance between + and - power in on mainboard is 14.9kOhm
Resistance on DC board power out (to mainboard, not connected) is 5kOhm
Resistance on DC JACK is 0.5MOhm when not connected to mainboard
Resistance on DC JACK is 14kOhm when connected to mainboard
Thank you for reading and I hope someone can help!
