I have a similar problem and am looking for a solution.
My problem is that I bought my MSI GT70 off of Craigslist and I checked everything is working fine. I get home, battery gets low, plug it in the wall and it dosent charge. I'm like $hit!
So Diagnostics are...
1-Plug in the wall charger and battery, turn on...nothing
2-Remove the battery, keep the wall charger.... nothing
3-Remove the wall charger use only battery, it turns on, for 3 min because the battery is empty.
So my conclusion is something is wrong with the wall charger or loose adapter or something.
I disassemble the laptop according to the following:
1-
A picture illustration with detailed descriptions, very helpful to keep track of screws etc
2-
Video step by step disassembly when the pictures aren't descriptive enough
I came to find the power adapter where it accepts the electricity from the wall to the motherboard fried a pin on the motherboard, one of the adapters pins. I hope I can simply swap out the adapter and call it a day or even beret just solder it back on like Jim Lawrence did. I have a simple soldering iron and I think I can get it done. But I want to know what caused the problem so I don't break the laptop after I hopefully fix it. Maybe someone connected the wrong power adapter and gave it too many volts? Maybe it simply overheated (I doubt it)?
I hope that I don't have to change the motherboard because a new one will cost me $450 on eBay.
Can I get some help? Advice? Anything! This is the first time I disassemble a laptop to the core. I am tech savvy but definitely a rookie.
