What Wires Do I Need For A Dc Jack-laptop Repair - Meaning

The pins from inside of my laptop's 3.5mm headphone jack are not tightening any plug properly. Is there any way to fix it?

Depending on your laptop, you can either replace the headphones socket with a wire harness connected to the motherboard, the same thing many do with the power plug. Or if it’s soldered to the motherboard, it may need to be replaced and then find the appropriate new headphones socket and have it replaced. The labour should be about 2–3 hours in total if the motherboard needs to be removed, plus about $5–25 for the new plug, and sometimes it can be more labour if its a tight fit device. The price is fairly close even if the headphones plug is attached to a wire harness, due to the amount of items you need to remove to be able to get at then headphones plug, the wiring harness, and where it connects to on the motherboard.Some devices are really tough to take apart, time consuming or parts just aren’t available, forcing you to use used parts or get parts from some other dead device. This was a very common practice in the old days.

What are the coolest hacks you can do soldering a laptop motherboard?

Thanks for the A2A, but the only one I can think of is externalizing the power adapter port. I did a number of cheap and dirty repair jobs on broken laptops when I was in Tallahassee… hell I was homeless repairing laptops for college kids hanging out at the coffee shop. They had no money, and no time to wait for parts.So… I’d remove the damaged power adapter port, and instead connect heavy gauge insulated wires. I’d secure them in the case, so as not to strain their connection to the motherboard. So now there are two wires sticking out of the hole where the power adapter went in. I’d then attach one half of a $1.99 polarized power connector from Radio Shack…RadioShack 2-Position Male/Female Polarized Connector ($2.50 now)… to the wires coming out of the back of the laptop, and the other half of the connector to the power adapter.This might seem unusual, but there were distinct advantages.For one you could now YANK your power cord away from your laptop with significant force, and all that would happen would be that the power cord would orient in the direction of the pull, and then it would just separate like it was meant to. You could trip on the cord and it wouldn’t damage the laptop. The $2 fix was ugly, but stronger than the original pin-barrel power connector design that Windows based laptops use.I did that for a couple dozen people.

How do I fix the problem "plugged in not charging" on my Dell Inspiron laptop?

Thanks for A2ATry the following and hope that it fixes.Check if there’s any BIOS update available related to battery for your laptop model.Download and try to update but before updating perform below steps:-Power off the system.Disconnect any external peripherals (flash drives, printers, external hard drives) from the computer.Disconnect the AC Adapter and remove the battery from it.Press and hold the power button for 20 to 30 seconds to release the residual charge from the laptop.Reconnect the battery and the AC Adapter.Once the system is powered on and booted properly, re-seat the battery. Check if you still get the error or not.Boot the system to BIOS, tapping the F2 key on the Dell logo screen when you power on the system.Press F9 key to load BIOS defaults. Once done, press F10 key to save and exit. System will restart. Check if the error is still there.Try and wiggle the AC Adapter cable and check if that makes a difference.Alternatively, you could also try below steps:-With above 20% battery left,unplug the power cord from both laptop and wall outlet.Open the bottom cover and Remove the batteryDry Wipe the battery connectors with a clean cloth several times.Put the battery back in and cover,Turn the laptop on with battery only.Now plug power cord into side of laptop, then into wall outlet.Check if it returns to charging state.

My Lenovo laptop is plugged in but not charging. What could be the reason?

I have also faced this problem with my Dell Laptop. I have done a lots of research that time to overcome with this problem. First check that if the plugging wire is loose or not. If it is tightly connected then check whether the Laptop is getting charged with another charger/adaptor. This may be the problem of Adaptor of Charger also. If the Laptop is getting charged properly with other charger. Then replace your charger. Otherwise there may be problem in the software. Please check whether the BIOS is fully updated or not. If the BIOS is updated then do one thing I am telling the STEPs note it down:-NOTE: Don’t Uninstall BATTERY ADAPTAR uninstall CONTROL BATTERY METHODDon’t worry about that. It’s just a controller problem. Try Uninstalling the “Microsoft ACPI-Compliant Control Battery Method” in the Device Manger ->Batteries. If the Battery section is not seen in the Device Manager do the following: Control Panel-> Power Options and CHOOSE the POWER SAVER MODE and Check the Batteries section will appear in Device Manager. Plugged the charging cable into the Laptop and then Uninstall it. After that don’t shut down the Laptop remove the Battery directly. After 1–2 mint. insert the battery again. And in the device manager click the “Action” and Select the “Scan for Hardware Change” and See the PROBLEM HAS BEEN RESOLVED. If not Try RESTARTING THE LAPTOP it will GUARANTEE solved the problem if u have not problem in your wire or Battery.

Can laptops be charged via USB with a power bank?

Hi the following answer is what I provided for another question Ryan Sookoo's answer to Can I charge my Lenovo laptop with a USB?Yes it is possible. The battery may slow charge or just not reduce power when connected. I will provide the steps in how you can achieve this and the items required.ITEMS NEEDED:- DC to DC Step up power- USB cable (must be working and willing to cut it. An old printer cable or mouse USB can work)- Laptop charger (preferably not your original)USB power banks usually provide around 5V so I will tell you how to setup/test with the power-bank although it is not necessary if you don't have one.Obtain any USB cable and cut of the non USB endWith one end having a USB connector, strip the cable at the next end to look like the photo belowConnect the red wire to the positive input of the DC Step up inverter and the black to the negative.Depending on if the DC Step UP module you got has an LED interface you may have to use a multi-meter to adjust the output to 20v or equivalent to the output of your laptop adapter.When the voltage is properly adjusted you have to cut an old laptop charger to get the tip. DON’T CUT OF ALL THE WIRE. Cut so it looks like thisStrip the cable slightly so it looks like the picture and then insert the positive end of the adapter cable to the positive output on the Step Up Board and Negative to negative Output.If you have followed all steps correctly you should be able to at-least power on your laptop using USB connection.

What would cause a popping/crackling sound in one of my stereo speakers?

Most popping or crackling sounds in an audio system come from a bad or dirty connections. Sometimes they do come from a faulty unit or component, but in most cases it is a connection issue. Whether that connection is in the connectors, wiring, circuit board or components, or even just a bad solder joint, wherever that connection is, finding it becomes the main issue to tackle. There are some relatively simple methods that can be used to locate it.First identify which part of your audio system has the issue. The fact that it is only in one of your speakers is a huge help in identifying what might be causing the noise. If both channels had the same noise, this method would not work. You can easily identify the source by swapping the channels and seeing if the noise moves or stays on the same channel.For example, swap the channels the speakers are connected to. Does it persist on the same speaker or does transfer to the other? After swapping, if it remains with the same speaker ( other channel), then it is the speaker connections (or the speaker itself) that are problematic. If it is now on the same channel (other speaker), it is somewhere in the system, before the speaker connections. You can continue to swap different components back and forth, swapping channels and work back to where the source and component is identified.Sometimes just connecting and reconnecting the cables and components solves the problem, as the connection is improved. Good luck!One component that usually becomes noisy that way (more of a crackling sound than a popping one)is a potentiometer (also called a ‘pot’, normally volume controls, bass-treble-balance controls, etc.). These can be easily identified by rotating or sliding the controls as the case may be, and listening for the noise. These can be cleaned with the right solvents or sprays.Worst case scenario is a failed or failing component such as a transistor, capacitor, resistor, solder joint (actually solder joints are relatively easily repaired, just identifying the problematic one is the challenge!), etc.Once you have identified the part or unit in the system that is causing the noise, then it will be easier to decide how best to correct the issue (replace or repair).
