SOURCE: 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.

I need to connect a VGA dell monitor my Toshiba Laptop


HDMI is digital
VGA (the 15 pin connector) is analog.
If your connector has the digital to analog interface it should work, but likely it does not have that chip and thus will not work.

Your description of the problem tells me it may never work as you have it connected. Possibly it might be that the monitor is required to be powered on before the laptop is booted, but that only works in some cases.

I have also seen some work if a 2-step connector is used.
VGA to DVI connector, followed by DVI to HDMI connector.
DVI was the step toward digital that came before the HDMI standard was implemented and was only partially digital. DVI and VGA do not carry control signals nor audio. HDMI carries both those as well as the video.

YMMV but I think it would be cheaper and more efficient to actually purchase a monitor with a digital input (HDMI or DVI).
Without the digital/analog converter interface a digital output device (your laptop with HDMI out) can never operate an analog device (your Dell monitor with VGA input).

Dell d340. need to enter admin password in bios to reorder boot sequence to accept usb first - its locked and i cant remember password. tried removing cmos battery and replacing but no good. help!


Try the backdoor password Dell

With a PSWD Reset Jumper Step 1Open the access panel to the password reset jumper if your Dell laptop has one. Consult your manual for the access panel's location. Some access panels have a tab you slide, while others are held in place with a screw.
Step 2Pry the plastic cover off the reset jumper with your fingernail. The reset jumper is a small pin port labeled "PSWD" with three pins. Put the plastic back onto the jumper over pin 1 and 2 instead of 2 and 3. Wait 90 seconds.
Step 3Pry the plastic off the reset jumper again and place it back onto the number 2 and 3 pins. Turn the laptop on. Repeat step 2 if the password is still present. Leave the plastic clip on pins 1 and 2 for a longer duration than last time.

Without a PSWD Reset Jumper Step 1Locate the reserve battery, also known as the CMOS battery, if your Dell laptop is not equipped with a password reset jumper. The CMOS battery's location varies among Dell laptop models. Consult your manual for the battery's location on your specific Dell laptop model. Many Dell reserve batteries are located underneath the main laptop battery. Remove the main battery and look for a sticker under it with instructions on removing the secondary CMOS battery.
Step 2Remove your Dell's reserve battery per the instruction manual or sticker located under the main battery. Removing the reserve battery resets the laptop's BIOS password. Wait 90 seconds, then replace the reserve battery. Reconnect the main battery.
Step 3Press the "Power" button to turn the laptop on.

Dell inspiron 1520 how do i connect to my tv


The Dell has a VGA port 15 pin DSub connector and if your TV has a 15 pin viseo connector the you need a 15 pin video cable. Check the connectors on the Dell and TV so you get the correct connectors. You will need to select the computer input on your TV so it can display the Dell computer video images.

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 .

Ac dies nat charge battery


If you are using a non-Dell power supply, then the laptop will run but NOT charge the battery. The reason, is that Dell supplies have 3 pins in the connector; a center pin and an inner and outer ring connection. It's their approach to 'lock-in' customers, but it just gets them mad!

MY DELL LAPTOP BATTERY IS NOT CONNECTING WHAT IS THE PROBLEM?


Usually that is caused by having bent one of the pins inside the laptop. Take the battery out, and look at the connectors with a nice strong light. See if one of them has been bent, or has jammed under the plastic connector dividers. If the connector is normal, then check the same connector on the battery. Also look for any severe blackening of the points of the connector. If they need to be cleaned, then use a pencil eraser, and very carefully drag it across the pins.

Then carefully connect it and it should see it.

AC Adapters in laptops


It is not a special chip that dictates if a charger can charge a certain laptop, but these two factors:

1) You need to have a power adapter/charger with the correct voltage and amps. Some common Dell laptops use 19.5V (volts) and 4.62A (amps). I have seen some Dell adapters with 3.34A (amps) as well. If you use an adapter with the wrong voltage and amperage, you could cause damage to the laptop's power supply and/or motherboard...or it just won't work at all.

2) The type of connector to the laptop. Different manufacturer's use physically different connector sizes and shapes. Some are larger and circular with a pin in the middle, while some are smaller with no pin. It depends on the laptop.

You can look at the voltage of the original charger on the brick part (the middle of the cord that looks like a brick). Make sure you get one that matches exactly.
