If your laptop is not on the list, you 9ll have to figure out yourself how to take it apart.<br><br> For this repair you 9ll need the following tools. 1. Soldering iron or soldering station.<br><br> I use Weller WES51 soldering station and for this job I set temperature to about 800-850°F. 2. I use high-tech rosin core silver-bearing solder from Radioshack with diameter 0.0223 ( Catalog #: 64-013 ).<br><br> I think standard rosin core solder will work just fine. 3.

The positive pin is not making a good contact with the motherboard and because of that power to the laptop cuts off when I move the power plug inside the power jack.<br><br> I 9m going to desolder the power jack from the motherboard, clean contacts on both power jack and motherboard and then solder it back in place - this is the proper way fixing the power problem. Start desoldering process with adding some new fresh solder to all three contacts. This will make old solder more flowable, easier to remove.<br><br> While heating one of the contacts, remove the solder from this contact using the desoldering pump. Repeat the same steps with all power jack contacts until you remove as much solder as possible.

Most likely you will not be able to remove the power jack the first time because there will be some solder bridges left between the contacts and traces on the motherboard.<br><br> Carefully wiggle the power jack without applying any significant force and at the same time heat up all contacts one by one. This will help you to remove the power jack. The DC power jack is almost removed from the motherboard.<br><br> Be careful. Inside the positive hole there is a copper sleeve witch connects the terminal on one side of the motherboard with the traces on the other side. If you are removing the power jack with force, you can pull the sleeve from the hole.<br><br> You don 9t want to do that. UPDATE: If you accidentally removed the internal sleeve, check out this post: How to fortify damaged power jack connection . So, do not apply any force and make sure the solder is melted when you are removing the power jack.<br><br> I hope you understand what I 9m talking about.

In order to get video on the external monitor you need three main components: mainboard, CPU and memory. I assume the video card is integrated into the .<br><br> If you get no video on the external monitor, it 9s either between these three components OR one of them is bad. You said the memory is OK, so it 9s either bad CPU or motherboard. From my experience CPU failures are very rare and if you didn 9t remove it while fixing the jack, most likely the CPU is OK.<br><br> I guess there could be a problem with the motherboard. Could I have damaged the motherboard or the video chip? It 9s possible.<br><br> motherboard bad connection Submit Comment Laptop Repair Help » DC power jack repair guide.
