    Excellent advice. I now know not to destroy it and have a rep fix it. Thanks so much for your time and effort.

    I have the same problem. I've removed all the screws, drives, memory, and cooling heat sinks sinks but can't get the bottom cover or rear cover off. It appears that the rear cover must come off before the bottom cover will come off. The cover appears to be stuck on the side where the video and lan ports are. Can you walk me through the steps to remove that cover?

    Thanks

Hi, by dc power jack, if you mean the one at the back of your toshiba laptop, to replace, you may have to completely disassemble the unit and expose the back of the printed circuit board. This would involve removal of several small screws, panels, brackets, devices (hd. kb, cd, etc), connectors, cables. The screws would normally be small philips + but others might require a torx driver. Once the back of the main pcb is exposed, you can proceed to desolder the jack. normally there are 2 or 3 solder points. Simply insert the new jack and solder in place, reassemble and that should do the trick. However, if you are not comfortable with disaasmebly and soldering, it might be to your advantage to let somebody technically trained to perform the replacement for you. Hope this helps. Please let me know how it turns up. Regards.

Will not power on

When you connect the power, does the charge light lit up? this would tell you the power is transmitted to the battery, wich would mean your DC-jack (where the power goes in) is fine, and the problem might be fixed by:
  1. removing the battery,
  2. remove the power,
  3. hold powerbutton for 20 secs,
  4. re-insert power jack(not battery)
  5. press power on button.

If that didnt work, try the following to determine the DC-jack is the problem:
  1. remove battery
  2. insert power into dc-jack
  3. gently press the power plug into various directions while constantly pressing and releasing the power button.
  4. at some point the laptop should respond by turning on, meaning that you have a faulty dc-jack, which needs re-soldering or even relacement by soldering to repair.

Maybe you also notice that the power connector is very loose in the dc-jack, this might tell you that the dc-jack is the problem..

hope it helps..

I think I may have a problem with either the power cord or the DC jack in my 2200 Series Averatec Notebook. Even when it is plugged in, the laptop will not recognize so and drains the battery. I believe...

Hey

It's the plug that goes into your jack. Not the jack.

See what happens with the power cords is that when the wire nearest to the plug which it's connected to is bent or pulled it disconnects from the plug, preventing the power from flowing.

In a nutshell, don't move your laptop around while the power cable is hooked to it.

The solution I have for you my friend is to buy a new power adaptor for your laptop, DO NOT attempt at fixing it hence this can either causing injury to YOU or your laptop.

Best regards!

Can the dc power plug be repaired?

If you are referring to the DC Jack..(the port where your AC Adapter Plugs into) then typically No, THey are cheap enough that it is best to replace with new.... Yes they can be repaired, but chances are they won't hold up to the stress, and will just cause problems down the road...

Desolder The Faulty DC Jack... Go Slow, Use Solder Wick/Desoldering Braid... And A Solder Gun...Flip Motherboard to the underside of the DC Jack, You want to put a very small amount of FRESH solder on all Pin ends of the DC Jack - this will allow better flow of the solder when trying to remove...
Then Use The Desoldering Braid and slowly remove the solder from the DC Jack Pin Contact Areas... Do Not Rush or you will ruin the contact pads on the motherboard, you must make sure all solder is removed,,, if you attempt to rip out the jack cause you think its "good enough" you will end up pulling the C ring from the center of the Jack Pin Hole...

Once You Have All Solder Removed Use Some Flux Paste And Again go over each pin to ensure all solder is gone, then you can remove the faulty DC Jack...

Now.. Clean the motherboard where the DC Jack Was... Remove All Old Flux and take your solder gun and go over the Jacks contact pads so that you have fresh solder on all...

Now Add a small amount of flux to all the DC Jack Contact Pads and add alittle to the Pins on the replacement DC Jack.....

Then Solder The New DC Jack Into Place... Solder The BottomSide First... The Pin Ends ..

Then Flip Over and add small amount to the side negative pins and the power pin(s)...

Now you are done..

You can add Some Heat Resistant Automotive Epoxy ( Safe On Electronics) to the sides and back of the new dc jack.... this will double the strength and prevent future damage/wear and tear...

Acer 5920g no power

Your DC Power Jack is bad, or the area of the motherboard where the DC power jack attaches to, is bad.

The DC Power Jack, is the small port where your AC adapter,(Charger), plugs into.
This is an example of an average DC Power Jack, for an HP Pavilion laptop, not installed in a laptop yet,
http://www.megaemarket.com/dc-power-jack-hp-pavilion-ze4200-zt117420011721182125.html
If you click on the photo it will enlarge.

The DC Power Jack in the photo is upside down, in relation to how it sits on your laptop's motherboard.
Those flat metal pins shown on top, go down through the motherboard, and are soldered on the other side.

1.Sometimes when the 'charger' plug is in the jack, and is bumped, it can crack the solder joints for the DC Power Jack's flat pins. This makes an intermittent contact. Eventually there is no contact at all.

2.Sometimes it's a bad design of the DC jack, and just from ordinary usage of the user plugging in the charger, and removing it, this can crack the solder joints.

3.Sometimes the small area of the motherboard where the DC power jack is mounted, can crack away from the main body of the motherboard.
To explain:
Crude example;
Envision a laptop's motherboard as having a 1 foot square shape. (It isn't. It's irregular shaped) Now on one side attach a 2 inch square. This 2 inch square, represents the area that the DC power jack is attached to. A 'Peninsula', if you will. There are circuit traces that go along a motherboard. Think of them as Very, flat, thin, strips of copper wire. These 'wires' become stretched, and break as the 'peninsula' cracks away from the main body of the motherboard.

Solution?
Have the DC Power Jack replaced, or the motherboard.
DC Power Jack cost? About $6 to $8 dollars.
Labor? $100 to $150.
The tech has to completely disassemble the laptop, to just the bare motherboard in hand. Then unsolder the DC power jack, resolder a new one in, and reassemble the laptop.
Motherboard cost? About $150 on up. Depends on where you obtain it. (Ebay?)
Labor? $100 to $200.

Need to replace power connector on Acer extensa 4620z I have the new power connector

its so easy to write but tell you what its damn hard to do.

you need a very powefull desolder that can reach 350 degrees or else a 150W one.

the trick is to put more solder underneath each hole and so the new solder mixes with the old one and then it will melt.

you need a sucking pipe to **** solder out "without this u cant"

once the old jack is removed its so easy to put the new one and I am not even gona bother tell you how because i am sure you're smart to figure that out yourself, because if u get the old out you can put the new one in.

b very patient, take breaks, dont apply too much heat so the bits near the dc jack wont come off because of the heat.

check that solder isnt shorting with anything else.

Dc jack removel

I believe the DC jack is soldered to the board on that model. It must be unsoldered to remove (from the bottom of the board) and the new one soldered on. A soldering iron and a solder sucker (to cleanly remove hot solder) can be bought at Radio Shack, HOWEVER if you've never soldered before I would NOT ATTEMPT TO DO THIS REPAIR MYSELF! It's very easy to toast the motherboard if you don't know what you're doing. I would suggest finding a local electronics/computer repair shop that knows how to work with SMT components. Ask them for an anti-static bag for the motherboard and just bring the motherboard and new jack down to them to have the new one installed. It shouldn't cost more than $40 to replace that way and more like $20-30. Good Luck, El Duderino
