A1342 Suddenly shuts down during boot
Recently I bought myself a 2009 Macbook A1342. It was sold as "deffective" and I want to repair it.
The thing is when it boots, the fan is spinning at full throttle and after some seconds it shuts down. Because of the year of manufacturing, I believe the battery is dry so my plan is to use it attached to the power source (16.5V and 3.65A), but the problem even happens when the battery is disconnected.
I installed a known-good RAM memory and also changed the HDD with no success. Also installed a caddy instead of the DVD drive, just in case the HDD SATA was defective and same thing happens. I even got another mainboard and the same symptoms persist.
The only thing I haven't changed is the magsafe conector because I have noticed the magsafe charge indicator doesn't turn up when is connected.
Does the fact of using a non original power source adapter have anything to do?
I have bought a new magsafe adapter and I am having same problem. But the most weird thing is that when the main board an the magsafe are not attached to the laptop and I connet the plug the green/orange light turns on, but this doesn't happen when the board is in the laptop.
Maybe my trouble is because somehow, when the magsafe is in the laptop the power adapter doesn't make good contact in any of its pins, so the light doesn't come up and then there is not enough power to completely boot up the system.
Any suggestion is welcome.
Es esta una buena pregunta?
