4150 Start up Problem
My 4150 recently can not start up by AC adaptor, but it can start up with no problem using Battery.
The AC adaptor works fine.
And I chat with the dell tech, she said it might be the AC adaptor port on the mother board, so what do you guys think about this?
would it worthy to repair it?
Is there any good place to repair the Motherboard, not just replace a new one?
Thanks a lot, this is my first time to post, hope I can get some help, I spent lots money on this notebook, now the warrenty is gone, I am a little worried.

If the board is cracked or damaged, it probably cannot be repaired.

GeekSquad is Best Buy - I doubt they're equipped to do surface mount rework.

I can be fixed if you had the same problem as me.
I finally found my solution to no charging problem with my 4150 after taking it apart 3 times. I checked the boards and there is very little in solutions offered other than changing the mother board. I found an old post for a 4000 that talked about a broken power jack and soldering on a new one to the MB. That wan't my problem. After close inspection of the MB, I found a small block labelled FL1. The first time I opened the computer, I checked for voltage and it looked ok, but still no power. Back to the forums and no solution. As a final last ditch effort, I opened it again and poked at the FL1 and saw very small cracks in the solder where it connects to the MB, resoldered them, and now it works!!!
Now, I have found that power problems are very common with these computers.
from my hours of research, I have found that the jack is usually the problem, but if it is not, check the FL1. I am told that it is the motherboard's fuse. Tech support will not tell you about it. They want to sell you a new computer or MB. It can be repaired or replaced with a generic fuse. If your computer powers up in a docking station, that is the biggest clue. There is also a recall on some of the adapters that are defective. Overheating is common when dust clogs the fan and heatsink. Vacuum it out. You can download the disassembly instructions from Dell. If you have a broken power jack, you can find on this forum, instructions for making a replacement (again they are for the 4000 which refers to running a wire from FL1 to a spot on the MB to charge the battery. Skip that part) If you are handy with a screw driver and solder gun, it is well worthwhile taking an hour or 2 to fix it. Be very careful not to damage anything else or overheating the motherboard and components. You will have to completely dismantle it to get at the FL1. There is a hole in the bottom plate under the MB where you can see FL1, but I found it too small to reach through with my solder gun. Since you have already gone that far, you might as well take it off. If Dell spent an extra few cents on these computers, they could have installed a small replaceable fuse underneath. Just a small access hatch in the bottom of the computer would be needed.
