Inspiron 5150 AC power problem - system board repair
Well I've been thinking about repairing the board for sometime now and now I've just finished it : I dis assembled all the parts according to the instruction manual to
get to the motherboard. when I did, I found out there were few AC contacts on the board need re soldering because I could see cracks in the old solder.
I kept track of all the parts and screws,so I knew how everything would go back together again. I re assembled all just like the manual,took care of
the safety instructions like preventing static damage and so forth. Plugged it in and the yellow and green led lit up blinking which means it's charging and seems normal but when I push the power button it starts up by making the regular noise but after like 20 seconds it shuts down the power!! I did this 3 times and it shuts
down again. my question is: Is there any trouble shooting sequence for this kind of assembling that I can follow and figure out what went wrong? I'm just
so disappointed that don't know what's next or this is the end of it!!?

There are no AC components on a notebook mainboard - exactly what did you repair? The AC power ends at the power brick outside.
Did you do this properly - with a low-temperature soldering jig? Or was it a hack job with a soldering iron?

I re soldered 3 or 4 contacts of the female jack on the board where the male ac would go in. But my soldering iron is 40W .Is it too much? If so
then what do I need to do next? I also had to glue that female part on the board because it was kind of loose and for the same reason it would
disconnect frequently and it wouldn't charge the battery.Now the battery is charged after about 18hrs being on the ac adapter.
