Re: Dell Inspiron 2200 loose DC power pin connector
It seems the Dell Inspiron 2200 DC in power jack connector coming loose is a common problem with this laptop, unfortunately. If you want to try it yourself, grab a copy of the service manual which will guide you through the process of taking it apart (as well as putting it back together). Once you have the motherboard out, check the solder points on the bottom of the circuit board. On one I worked on, there was practically no solder left, but the jack itself was solid. Be careful with the soldering process, because there's an RV1 component too close to the power jack's pins and you can easily dislodge it if your soldering iron / tool isn't precise enough. If things go well, and the solder goes where it's supposed to, that should fix it.
Some people replace the jack entirely - a call you'll have to make yourself.
Re: Dell Inspiron 2200 loose DC power pin connector
Not that hard to do the repairs yourself.....The pin assembly is usually available on the web for $ 10-$20. Take your time taking the unit apart, take notes on the dis-assembly so when you go to re-assemble the unit you know what goes where. Once you get it fixed you might think about getting a cable retention device to keep the problem from re-occurring.
a 6ya Technician can help you resolve that issue over the phone in a minute or two.

You are right, most of the situations like this end up that the charging connector fixed / soldered to the motherboard get damaged because of shaking the connector when ever we connect and disconnect it .
1. Test power adapter for output voltage. Bend the power cable in various directions while doing this to be sure that there is no broken conductors in the cable. 2. If power adapter is Ok, connect it & see if the power LED on the laptop will glow when you jiggle the power connector in various directions. If yes, then the DC jack might be loose or damaged, & need to be either re-soldered or replaced. 3. If not, then disassemble the laptop. Remove any components that attach to the laptop's motherboard first (e.g. battery, hard drive, RAM, wireless card, optical drive, ... etc.) 4. Next, remove the keyboard & the LCD screen. 5. Finally, unscrew all screws that hold the upper cover & lower cover together so that you could gain access to the motherboard. 6. Inspect the solder points connecting the DC jack to the motherboard. Make sure that none of them is loose. If any, re-solder them. 7. Inspect the center pin in the DC jack. Make sure that it is not broken or loose. If it is, then you might need to replace the DC jack. 8. When you are done, re-assemble back the laptop.
Try attaching an external monitor to the laptop & see if you could get any display on it. If this is successful, then you might have either a faulty LCD cable or screen inverter board. The
LCD cable transfers data signal from the motherboard & video card
to the LCD screen. It also supplies high voltage DC power to the screen
inverter board. The screen inverter board works as a power supply for
the backlight lamp mounted inside the LCD screen. It converts low
voltage DC power to high voltage AC power needed for the backlight lamp
The connector is special to Dell, and not generally available. You may need to purchase a new power supply. The connector has 3 concentric terminals, and one is used to 'ID' the power supply as genuine DELL. A plain DC connector can be used, but the batterys will not charge.
Hello, If your screen is dim but still displays everything then please check if the screen's brightness has not been accidentally reduced. If that is okay, then you have a damaged screen inverter and it needs to be changed. If the screen does not display at all, then you may have to change your screen.
Take the laptop into a darkened room.
Does the correct image show, but very dim ?
If so, then the "back-light" in the LCD has failed.
It's about a $20 part, and it will take a qualified technician less than one hour ($60?) to disassemble the laptop, replace the part, reassemble, and then test the laptop.
You have either a faulty connector plug on the power adapter which connects into the laptop or the loose power input socket on the laptop is faulty. This is because you need to press the connector upwards to make electrical contact.
Test the connectot plug on the power adapter with a multi-meter, wriggle the connector to see if your get the voltage to fluctuate, if it does not then the connector is OK anf the fault is in the laptop power input socket.
If the fault is in the power adapter plug or the laptop's power input socket, this can be repaired, a techo would have no trouble in repairing these faults.
This could be a couple of issues. One, the computer could be over heating and shutting down. Ask her if her laptop was warm and if the fan was constantly running. The second possiblity is the cord that plugs into the laptop has become loose and once wiggled will cause it to turn off because the battery doesn't hold a charge. Have her put the laptop on the table and with the computer running wiggle the cable. If it shuts down its a bad connector. In this case find someone with mad soldering skills and re-solder the connector on the motherboard.
Armymason If this sounds like a good solution a high score is appreciated.
click your "fn" key and then press the brightness key on the keyboard (it will be a blue or green "sun")
If this does not work, plug an external monitor to the laptop, if the screen is good on the monitor, your LCD display panel is shot.
