Question about Dell Latitude C400 Notebook

On AC Power

My problem lies on the power side of things...When I connect the AC adapter/charger to the laptop, It has to be jiggled and moved around to enable the "On AC Power" indicator. (Pic of AC in taskbar) Is there any way to test whether the problem is coming from the AC adaptor or the DC on the motherboard...without going out and spending $100 for a new cord? I could really use any advise or direction...

Thanks in advance...

Here is a tutorial on how to resolder the DC jack:

You would need to take your laptop apart down to the system board. Here is Dell's site with the service manual:

Your problem most likely lies wih the laptop power connector, the power cord connector is not making firm contact, that is why when you jiggle it connects. It might be the cord, you can check it by connecting it to another laptop exactly like yours and see if this plays up on that laptop, if it does then it is most likely the cord/power adapter. Don't connect it to a different brand name laptop, different brands use different voltages.

To replace the power connector on the laptop could be expensive unless you do it yourself, the laptop would need to be completely dismantled to get to the connector. Get a quote, they may charge for a quote, unless you accept the quote which may then be offset against the cost of the repair.

I recommend if the laptop is more than 3 to 4 years old, I would not repair it, put some blue tack around the connector to make the connection secure/firm, and put the repair costs towards a new laptop.

SOURCE: On AC Power

you can get the adapter tested by an electrician or someone with a multi meter....that would be the first step....if the problem resides with the DC in then you'll need a professional to sort that out....what often happens with adapters though is that they don't produce enough ampage for the P.C....might be worth checking Dell support to see if they've produced an adapter for your model with a slightly higher ampage ...

Laptop is turning on and off


Remove the AC adapter (Charger)

PROPER method is to disconnect the power cord of the AC adapter, from power; THEN unplug the AC adapter from the laptop.

Same thing in reverse to plug the AC adapter back in.
AC adapter is plugged into laptop, THEN AC adapter is plugged into power.

Unplugging the AC adapter from the laptop, while being plugged into power; can cause a Voltage Spike.

You may get away with it for years, and several laptops; and have no problems.

However it only takes ONCE, to fry out the SMD fuses, Multi-Layer Ceramic Capacitors, and Power MOSFET's, on the laptop motherboard's DC to DC circuit.

Jus sayin'.

Moving on........

AC adapter removed, remove the Battery.
Press the Power On button in, and hold in for a count of 10 seconds.
Let go.
Do this procedure 2 more times.

(Draining residual power)

Reinstall the Battery. Attach the AC adapter, plug AC adapter into power. Let the Battery charge 24 hours.
Then turn the laptop on, and tell me what happened.

Toshiba satellite won't go on


Hello. It sounds like either...

1. Your power adapter is damaged/not working. Look and see if a LED is illuminating on the power adapter. If it is chances are it is working fine and the problem may lie on your laptop. If not replace it. The easiest way to tell if your power adapter is bad is to go out to Wal-Mart or your local technology store and purchase one of their universal power adapters. They are expensive but you can buy it, try it, and return it if it does not solve the problem.

If you are going to buy a new toshiba ac adapter, you may consider the following toshiba l355 charger:
Replacement Toshiba Satellite L355 AC Adapter 90Watt 19V 4.74A

OR

2. The DC pin on your laptop is bent/broken/loose. Look at where your power adapter plugs in on your laptop. Get a paper clip, bend it out to make a long paper clip and slightly push its tip on the pin inside your laptop. If the pin moves chances are either the DC pin needs to be soldered down or needs to be replaced. The part is usually cheap around $10 but the labor can cost more than $50

My laptop is not charging. i plug the power in but still doenst charge. im not sure if its on the power cords or on the laptop please help asap i need my laptop for school :(


Does the laptop work on AC ? Is the battery or cord/charged a replacement? First, try another cord/charger of the EXACT same specs as original. Second, Is the battery good? How old? Over 4 years? Have it tested. Beware of inexpensive aftermarket batteries and cord/chargers. I assume the laptop works on AC? If you unplug the AC , with battery in, the laptop shuts down immediately?

AC adapter 4750z


The solution to your problem lies in one of the following three areas:

1.) Your charger is faulty and is therefore not able to pass power to your laptops battery.

2.) The charging connector on the laptop has come loose from the contacts. Therefore a bad connection.

3.) Your battery is faulty.

I think possibility 2 is the most likely, although you will have to test possibility 3 by removing the battery and plugging in your charger and seeing if the laptop powers on.If it does power on then that rules out possibility 1 and 2 leaving a faulty battery.

If you need to buy a new laptop charger, the following to adapters are for your reference:

How to open the Asus R33030 charger to fix loose connection?


Power adapters are sealed plastic units, but you maybe able to open them by placing the adapter on a flat solid surface with the sealed joints on the surface and hitting the joints with a hammer to break the seal. Move the adapter around so you can hit the joints on the other sides of the adapter.
After you repaired the adapter you need to join the adapter halves together again and glue it with super glue.

I have an Acer Aspire One and when I plug the charger in I have to spin it or wiggle it or both to get the battery to charge. Once I have it in position it generally stays on charge, but if the cable is...


It could be either one Sarah.

The AC adapter's (Charger) cable, or the DC Power Jack where the AC adapter plugs into the laptop.

This is an example of the DC Power Jack not installed,

http://www.laptopjacks.com/view_part/Acer-Aspire-ONE-AOA150-ZG5-DC-Power-Jack-AC351816.html

(You can click on the three views of the jack to enlarge)

1) Check the DC Power Jack to see if it's in good repair.

Battery removed use a small flat tipped screwdriver, and Gently see if you can move the Center Pin around in the jack.
See if the Center Pin will move side to side a small amount. There is supposed to be No perceptible movement.

Referring back to the closeup photos of the DC Power Jack, the flat blade-like prongs are upside down, in relation to how the jack sits on the motherboard.

The flat prongs go down through the motherboard, and are soldered to the motherboard.
If the center pin of the jack is stationary, but the jack as a unit moves around, one or more solder joints, (Connections) for the flat prongs may be cracked.

The repair consists of completely disassembling the laptop, removing the broken DC Power Jack, and installing a new one.

This is a PDF file. The computer you are using now has Adobe Reader on it which uses PDF files.
After you click on the file name (One) it may take up to 30 seconds before you see the first page.
It may also take additional time for the file to fully download.

(Took 12 seconds just now for full download)

No perceptible movement of the DC Power Jack? Suspect the cable of the AC adapter right near it's plug. (Plug that plugs into the DC Power Jack)

Will Not charge with brand new a/ power cord it will at times power on if moved the right way but quickly powers off if moved the port inside looks to be fine But I hear there is a pin type thing inside...


The problem is with the AC adapter itself and is a very common problem with Dell AC adapters. My suggestion would be to get an aftermarket AC adapter that can be purchased on eBay as the Dell adapter is around 100.00. You can pick up an aftermarket one on eBay for around 20.00. The problem is a resistor inside the AC adapter that senses when a Dell branded adapter is inserted. What happens is that the resistor will get damaged and since it doesn't recognize the charger as a Dell branded one anymore it won't charge. However it will still run the laptop as long as it's connected. A lot of aftermarket AC adapters bypass this function and work perfectly fine.

On AC Power


It does sound like a power cord problem. You can test it by getting a digital mulimeter and checking to see if there is 19.5 Volts DC power on the contact points of the barrel plug that goes into the laptop.
