DC power jack repair guide. Do-it-yourself instructions.

This guide will explain how to repair a failed or loose DC power jack on a laptop computer yourself. Here’s my previous post related to DC power jack related issues.

Disclaimer: I’ve made these instructions only for people experienced with soldering and repairing computers. If you don’t feel comfortable doing this job, please do not open the laptop or you can permanently damage your computer. Take your laptop to a professional repair shop instead.
Use this repair guide at your own risk.

First of all, you’ll have to disassemble your laptop and remove the motherboard.

. If your laptop is not on the list, you’ll have to figure out yourself how to take it apart.

For this repair you’ll need the following tools.
1. Soldering iron or soldering station. I use a 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 0.022″ ( Catalog #: 64-013 ). I think standard rosin core solder will work just fine.
3. For removing solder around component leads. I use Edsyn Soldapullt pump, model DS 017.
4. 99% isopropyl alcohol and tooth brush for cleaning the motherboard from flux.
5. A new DC power jack, you can find a cheap one on Ebay.

Start desoldering process with adding some new fresh solder to all three contacts. This will make old solder more flowable, easier to remove.

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.

Grab the power jack and carefully try removing it from the motherboard. 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. 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.
Be careful. Inside the positive hole there is a which 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. You don’t want to do that.

So, do not apply any force and make sure the solder is melted when you are removing the power jack. I hope you understand what I’m talking about.

After the power jack is removed, clean all oxidized contacts with a knife.

Apply a fresh coat of solder to all contacts on the power jack.

The power jack terminals will look dirty because of melted flux.

You can remove the flux using the tooth brush and alcohol. It’s not necessary but it will make your job looking clean.

Apply a fresh coat of solder to all power jack terminals on both sides of the motherboard.

Now you can install the power jack back on the motherboard. Put something under power jack so there is no gap between the jack and the motherboard. Now you are ready to solder the jack back in place.

Solder all power jack pins.

The job is done and the laptop DC power jack is fixed. B-E-A-utiful!
Now just install the motherboard back into the laptop and you are done.

A hard drive replacement for your laptop will be a common issue that will continue to plague the laptop owners and operators of the world until the laptop hard drive technology moves to solid state drives, as long as there are moving parts inside that harddisk we will have to put up with head crashes and bad sectors. That’s not to say that any new technology won’t have a whole new array of unseen or even unheard of errors and problems.. not giving you a lot of confidence in your data storage am I.

I have one word of advice..BACKUPS.

OK, back to the info…

A hard drive replacement for your laptop is generally one of the easier jobs to do yourself unless you have one of the makes and models of laptop that doesn’t provide easy access to the harddisk, hiding it away under the palm rest or worse still mounting it to the main board. Luckily there are not a lot of these and most of the laptop makers now recognise the need to have access to the drive for various reasons.

Replacing a drive is simple.. generally you can remove 1 screw from the HDD cavity or enclosure and the drive can be removed by sliding it out.

Guys, don’t undertake laptop computer repair without reading this first. I’ll guide you away from making costly mistakes that could render your laptop computer useless.

First of all have a good understanding of what it is you need to do and what you might need in the way of tools. A big mistake people make is to sit down with a part and their laptop and use whatever they have around to open up the laptop and replace the part.

What you should try and have before you start..

1 x Philips Head Screwdriver type 0

1 x Philips Head Screwdriver type 1

Tweezers ( long nose )

ESD mat or grounded ESD wrist strap (ElectroStatic Discharge)

Needle nose pliers

A Teflon wedge or splade

Also take a look at the environment you are going to do your laptop computer repair in, static electricity can ruin your day and you won’t even know it..

Back up your laptop’s hard drive just in case you do something you shouldn’t have. Avoid doing your laptop computer repair in a carpeted room, use the kitchen or garage.

Keep in mind that if you are playing with the LCD the backlight inverter can give you a nasty shock if the unit is powered, switch the laptop off and unplug it, you should also remove the laptop’s battery and hard drive.

I understand that most people won’t have any anti-static gear like wrist straps and so on but if you are going to be doing some laptop computer repair on a regular basis, it may be worth while getting some, although the laptop you have may be a cheap one there is no point killing it off and dumping it in the trash.

Some points to remember when undertaking laptop computer repairs..

Don’t disassemble a machine if it doesn’t need it.

Use the right tools.

Try to do it in a clean environment.

Test the machine properly beforehand

Keep any parts you remove in a safe place.

Keep the screws with the parts they have been taken from.

Put the right size screws back into parts when it’s time to reassemble it.

Observe how connectors work before disconnecting them.

Make notes for yourself if you need to as you pull apart the machine.

Check all cables and connectors are fastened as you go along.

Try not to use screwdrivers to lever or remove plastic parts.

If a part won’t budge look for hidden screws or a screw you may have missed.

TAKE YOUR TIME.

Note: Some laptops have the screw holes marked with screw types and sizes. Some use symbols to indicate screw types. Take notice of what screws come out of where.

The laptop computer repair tips page is subject to many variations for different laptops and it is hard to be very specific. We have put this page together taking best and most common practices in mind.
