I have a notebook with power issues. I know the cause and what the problem is. Repair information is what I am after.
The Power jack on the notebook is loose and does not always allow a good power connection. Ill be sitting and working, all of the sudden the low battery alarm sounds. I reach arround to adjust the cord and sometimes I get a good conection.
It has become more frequent that I can't make a good connection. When I do manage to get a good connection I have to be still. The slightest movement will sound the alarm. It is a question of how much longer it will even work, then I have a dead PC.
The cord is good. I have tested with a voltmeter. The power is steady even if I bend the cord at the connector. So then, How do I fix the pin in the jack. Is there a way to tighten it? I am very fuzzy in this area but skilled with solder. I have thought of applying solder to the outside of the plug end (on the cord) to try and get a better connection.
Let me know what you think

you are going to have to open the laptop so as to get at the bottom of the board to resolder the power connector. once exposed remove all the old solder with heat & a solder wick or a solder sucker. resolder the connector pins with new solder. you might have to replace parts of the pads or circuit tracks but don't know yet til you have exposed the connector pins

I was affraid of that response. This notbook is a pain to open. Had to open it once to remove something stuck on USB. Took about an hour to get in. To bad the plastic supports are broken on both USB. Anyway I will have to wait till tomorow to crack this thing open. Ill post results. Should I find a replacement part for this?
Thanks

might be able to use the connector as there is possible cold solder joint that is causing the problem. if board is open might be able to replace usb connectors. i do this work all the time so know what i'm talking about

Oh Yea!! Lap top now fixed. I did not do anything to the jack. Was afraid I would not be able to get solder through all layers. So here is what I did.
I opened the computer and soldered Two wires to the bord where the jack connects. I ran the wires out the laptop lock slot. Yes I tied a knot in the wires to prevent pulling out. I then attached the two wires to pins. The pins went in a plactic socket. Finaly I cut off the end of the adapter cord. I took those two wire and put them on pins and placed inside the other half of the plastic piece. So now the power hooks up similar to a power supply outlet into a hard drive or something. Now it all works fine.
Total time of project: 3 hours. So there you have it.

Oh Yeah about the USB connectors. I discovered they are on thier own seperate bord. Tiny bord held in place by 2 screws. I wrote down the part number and will begin looking for it.

the solder would have flowed thru the barrel that attaches all the layers together as it is plated

I have the same problem. I got my notebook last year in August and in the end of September I smelled plastic burning. After while I found out that my AC plug is melting, from the beginning I was thinking that the problem is in the AC but it appears that the issue is in the power jack.
In order to get connection I have to adjust the angle and after that it starts making some ?electricity? sounds and gets hot. I still have warranty but I can not afford shipping fees. I was thinking to give to some company to fix it, but I?m little bit hesitating to do that. You never know what they do.
Is my problem very serious??? And how to deal with it???
Any suggestions/ ideas???
Thanks in advance,

Ghuch, anytime that you smell plastic burning, you have a huge problem. Contact the vendor who sold you the unit, and tell them what has happened. Maybe they will cover the shipping charges for you.

This is a shot in the dark. Does your power supply have three prongs. If so do you use a converter so you can plug it into a two prong outlet. If this unlikle hunch is correct then install a three prong outlet correctly. Pluging in laptops like this do cause many power related problems. There are always exceptions. Like I said this is just a hunch and may not even apply to you.

you have a break in 1 of the wires that is causing the electrical sounds & causing the cord to get hot. in effect you have an electrical short that can catch fire & burn your place down so get it fixed ASAP!!!!

I do have three prongs and do use convector with two prongs and the third one is just hanging out.
So what think do I have to change the whole motherboard or I just have to replace the power jack.
I just contacted with HP center they dolt me that I might change the whole motherboard, because the jack is integrated to in.
What do you think is may problem is big one or is that just power jack???

DDP You are probaly correct but it is highly likely the source of the problem was the outlet converter. Now the damage is done and must be fixed.
As far as replacing the outlet, You must make sure there are three wires behind the exsisting outlet first. If not then you will need and electriction to run to proper wiring. If there is three wires then you will connect the lose one to the new outlet. Simply replacing the outlet to three prongs will be inefective if you do not have that third wire. Im guessing you have an HP,Compaq or Dell.
By the way, If you choose to send the notebook in for waranty work don't tell them you used a converter. That will void the warenty. iIt is even in your manuals not to use one.
Good luck

I checked my AC cable on another notebook just like mine and--- even my AC plug is half melted it was working perfectly no problems at all no sounds and ugly stuff.
So as it seems the problem is power jack!!!!
HP told me that jack is integrated on the motherboard. And if the problem is jack is it easy to fix??? Do I have to replace only that???

if still under warranty get it replace because if you open it, you could void all warranty & is possible there might be a recall that they haven't told you about so send it in to be fixed by hp

Sounds like the same problem I'm having. I've got an HP zt1150 that started smoking. After ripping the thing totally apart, I have found that the tiny power receiver box where the power cord plugs in has been fried. It was loose before and I'm sure it just wiggled until the soldering came apart. There was probably an arch when I plugged it in that charred the box. I took it to CompUSA and they said they could resolder it for $800. I'm willing to give it a try myself for that much!!! Anybody have a clue where to get one of those boxes. I found one at Radio Shack that was close, but a not close enough. It has the number 020408 on top of it. It has 3 prongs that would solder into the motherboard, but one of them is TOAST. No way to solder it. If anybody has any ideas where to get one, please let me know.
Thanks!

take old 1 to an electronic supply store to see if they have same or similar type 3 prong jack. if can't get same than get 1 of same size & layout & that the pins do the same thing as old 1. $800!! i can do that for a lot cheaper than that as that is what i had worked before fixing/repairing circuit boards

i have a similar problem. about 3 years ago, the power jack on my laptop (only a year old then) broke so that i had to hold the cord in a certain position to get a connection. i had it fixed at a local computer place and it's been fine until now. it's doing the same thing. i know much more about computers now and i would rather fix this problem on my own rather than dishing out another $100.
when i open the notebook, what exactly will i need to do? do i just need to resolder the jack or will i need to replace it completely? i found the jack i need on ebay for only 5 bucks or so. would i just need to get that?
thanks

when you open the inside of the laptop, look at the prongs that go thru the circuit board from the jack. wiggle carefully the jack to see if just the prongs move or the prongs & the solder move. post results

My machine still suffers from the same problem. I went to local HP office and explained the issue, the guy told me that he has to look inside and will tell me if it fixable. So after three days I give them a call to check up what?z up? Unfortunately, I had negative answer. They could not fix it because they were not familiar with the motherboard and the only thing that I got from them was that I have to change the whole motherboard.
I?m pretty sure that the problem is in the power jack, but lately I have observed that if I put my plug from AC into the computer and will hold the cable in horizontal position, I still able to get power into the machine. It still makes electrical noises but there is not much that I can do.
As I have mentioned in my pervious massages I still have warranty. When I asked to the guy who opened my machine about warranty, he said that they have not touched anything inside just opened and there nothing happens with warranty. However, when I got my laptop back, I noticed that there is missing one screw.
I?m voiding warranty? i want to fix it in the sates.

If what you say is true then the first thing you should do is kick those guys in the nuts. You should not say you service something you don't understand. About the srew. will depend on when they notice it is missing. If the see it before they start surgery then your probaly screwed. If they catch it after surgery then your OK.

My Dell Inspiron 3800 stopped powering up using the AC Adapter, the only way I could use it was with the battery. At the end the battery was depleted. I found this company through google and they did the job. Desktops are much more durable. Their web page is: www.tech4home.net/powerjacksinfo.html.
I bough a new Toshiba machine, so far so good... hope nothing happens to it.
