Hello everyone.
I'm having a very annoying problem. While I'm sure that most would find it a rather hilarious reading, I shall cut the long story short...
The laptop got water damaged and HDD failed. As the battery was fully charged I figured after I installed new HDD that perhaps the adapter died as the laptop worked perfectly fine but wasn't charging. After I got a new adapter it still wasn't charging the battery. However, in the meantime the battery ran out of charge and died. It then transpired that adapters are fine but somewhere in the charging circuit between power socket and motherboard something wasn't right.
I'm trying to figure out if it is possible to fix this, however I am unable to find any diagrams or references for the motherboard in question so i can't establish what may be causing the issue.
the first image is that of the motherboard itself (sorry about huge images, resizing them didn't work and .. well.. I didn't have time to upload new ones)
next image is of what i believe to be an issue part of a circuit
as you can see, first MOSFET is working and showing 19.34V on all S and D pins. the tiny (?? can't even see exactly what it is, is reporting power, but nothing toward battery terminals is reading any power. Since the battery is now dead and I don't have any others to try it on with I can't check which circuit sectors being fed from the battery itself are working.
I really need to figure out the problem and try to get it fixed. Laptop is just over a year old and it will be some time before i can either afford to get a decent replacement or buy a new motherboard. In the meantime, I am all up for troubleshooting, soldering, rebuilding or whatever I have to do to get this puppy going again.
