A laptop charger is essential to have on hand, and replacing one is a pain and can be expensive. There are a few simple tips to follow when it comes to extending your laptop charger's life. Laptop chargers have two parts: a transformer and a power cord.

ATX, WTX and other standard and proprietary power supply (PSU) cables connectors pinouts

The transformer is the brick that converts the current from your power outlet from AC to DC, and the power cord connects the charger to the outlet. Over time, transformers can overheat, which can cause internal damage. Simultaneously, any section of your power cord can wear away and expose the wires inside. Maintaining your laptop charger's integrity will help ensure you can safely charge your laptop with it.

Here are six ways to do it. While it may be tempting to wrap your laptop power cord in a tight pattern to keep it organized, doing so can shorten the life of your charger. This practice puts repetitive stress on the thin copper conductors inside power cords and can cause them to break. To avoid this, loop your laptop power cord loosely to avoid crimping the wires and if you can wrap it a different way each time to avoid repetitive stress on the same section.

But not just any power strip——make sure it has a built-in surge protector. In addition to offering convenience allowing you to plug in multiple devices with only one outletpower strips with surge protectors can protect your laptop, phone, and other electronic devices from power surges that can damage your device.

The transformer can get hot during the charging process. To avoid overheating while your laptop is charging, make sure it's placed somewhere with plenty of airflows e. Exposed wires are a big no-no, and extended contact with sharp surfaces like table edges can wear away the rubber protecting the wires in your laptop power cord. Whether you often move your power cord from one place to another or have a designated charging hub, ensure your setup doesn't expose these delicate wires to sharp edges.

Water and electronic devices don't mix, so it's essential to avoid situations where your laptop power cord could be accidentally exposed to water as this can cause electrocution, damage to your laptop, or both. This means not charging your laptop in or near your kitchen or bathroom.

If your laptop charger comes into contact with water, disconnect it from the outlet at once and move it away. Thoroughly dry the charger and make sure it is completely dry before deciding whether to use it again. Of course, this means you'll have a backup when one breaks down. But opting to have two in your possession is about more than being proactive. It can help reduce the wear and tear of both — and will likely improve their life span.

Reserve a cord specifically for travel, and leave your other charger in your living room or bedroom. Only use the travel cord while you're on-the-go and the living or bedroom cord while you're working in the house and in those rooms. For you.

It only takes a minute to sign up. Connect and share knowledge within a single location that is structured and easy to search. I have an HP notebook that is dead. So I thought abount using its power supply to play around with my arduino and my DC projects. So I removed the jack of the power supply. The problem is that when I removed the jack came out 3 wires: black, white and blue. What is going on? Cant I use a notebook power supply as my hobby power supply for arduino, LEDs? I believe it is the remote sense voltage to the converter output.

It is usually fed back to a 2. If the supply detects a short circuit or an open circuit on sense feedback, it shuts down then the hiccup circuit retries to see if the fault condition is fixed.

I have used this feature in universal chargers to devise an adjustable output voltage with a trimpot and a few other parts like in an LM regulator ADJ.

It may be one of those "smart" power supplies that is expecting communication with the laptop it is intended to power. It powers up the laptop, but if nothing is heard within a few seconds, it shuts down.

The third wire is the communication channel. If this is really what is going on, then no, you won't be easily able to use it for hobby projects. If it's a popular model, someone may have reverse engineered the protocol or somehow obtained the specs and published them on the web.

Look around and you might find directions on how to hack the supply. It puts out I got the same reading before I connected the blue wire to white. But then I accidentally shorted the white and black wires and the power supply shut off and its LED went out.

So I tried touching the blue wire to white why not? The LED came back and on the power reading was the same So I soldered the blue to the white, covered everything with shrink tubing and it is running my little LMbased speaker just fine. I use a simple virtual ground circuit to create a positive and negative 9. So from my actual experience, here's what works: you can either leave the blue wire unconnected to anything or connect it to white. Sign up to join this community.

This is done via the pins or pins connector. Type 4. Easy quick connect and disconnect coupling. The original ATX systems had pin main connector P1. The motherboard has a pin eatx and a 4-pin atx 12v connector. Connectors really do get hot if you overload them so the safest thing to do is use a real 24 pin power supply on a motherboard with a 24 pin connector.

They were originally intended to interface the ICA to the AH2, 4KL or AT, but could be used with many other Icom radios of that era with the pin Toyota car stereo wiring diagram harness pinout connector. Thanks for the replies. Jadi dapat dikatakan bahwa konektor ATX 24 pin pada dasarnya merupakan konektor ATX 20 pin yang ditambah dengan konektor 4 pin, sehingga kedua konektor ini bisa digabungkan atau dilepas sesuai dengan motherboard yang … The compatibility rules between 4 and 8 pin connectors have a lot in common with the rules for 20 and 24 pin connectors.

Specifications: Featuring 90 degree turning, this connector can beautify the motherboard cord routing and reduce the height of the power cord. The new connector series reflects the trend with matching housings and inserts.I have a 90w power adapter from an older notebook that will work with my HP DVnr.

I transport my notebook between home and office. I'd like to utilize the older power brick, so that I won't need to transport a power brick back and forth. The tips on both adapters, of course, are of a different diameter. My multi-tester identifies that the tip is hot for both adapters. So do the black and white wires on the newer adapter need to be soldered to the shield on the older one?

Just a guess, since it is 90watt, they may have run the extra wire to carry the load, shield is always much larger than center tip wire.

If you want to chance it just connect the two wires that are on the center and outside. Leave the 3rd odd one unconnected. Using the outer part of the plug as ground black wirethe center pin shield wire reads 19 VDC.

I get the same voltage when measuring the inside of the cylindrical part of the plug white wire. Logically the hot shield and white wires on the new plug need to be connected to the hot wire on the older adapter.

I learned that the white wire to the inner side of the cylindrical shaft is solely for the power adapter's use: it measures the voltage drop between the 19VDC, feeding this info back to the adapter. How sad that HP was unwilling to be supportive and provide this information.

An electronics engineer that is familiar with Dell products kindly shared the info with me. HP used to offer the best support, but that no longer seems to be the case. Hi, Me too had an old HP laptop charger which died last night. Now I wanted to make my old laptop work again and needed that type of charger which is not available and tomorrow is Eid hollyday, so I am doomed. I have another HP product CQ41 which died 6 months ago but the charger remains. Checked working. So I decided to use it for the old one.

Still needed to change the plug. As I measured the connection with avo meter found black one attached to the pin in the toy freddy x toy bonnie gacha life, red wire connected to inner cylynder and the white one is connected to the outer cylinder.

So I connected the white wire to the shilding wire and red wire to the core wire of the old 90w adapter's plug. Didn't find what you were looking for? Ask the community.

Thread starter twm Start date Mar 18, The "smart" pin center pin on laptop power supply connectors is used for the purpose of the computer being able to determine the amperage or wattage, if you prefer of the I found a thread relating to this topicbut it is closed, and it did NOT provide the answer that I was looking for, anyways.

I believe that the pin voltage will vary between around volts to maybe volts. The higher the voltage, the more current amps the PS can deliver.

I run into the broken off center conductor wire scenario regularly. I suppose that is the one that always breaks first because it is the thinnest of the wires going to the plug, from the PS. I use one of those 6. But the interesting thing is that I had the PS connected to a Dell laptop once, and it would run the computer, but refused to charge the battery. When the PS was plugged into it, a message would come up on the screen stating that the type of the PS could not be determined.

Assuming that ALL brands of laptops now use the same type of power connector, is there any sort of "standard" among manufacturers that correlates center-pin voltage with PS capacity, or is it wide open to whatever they decide? If there is a standard, could someone please provide me with the link to some sort of "correlation table" showing center pin voltage vs.

PS capacity? You are talking about AC adapters right? I had a similar question when my Hp p 90 watt adapter with smart pin failed, I had a adapter with the right ratings but the wrong connector 2 pin laying around and was hoping to convert it.

I read a few threads looking for info and also could not find any conclusive awnsers. I expected some complex circuitry but it was a verry simple one. This is for a 90 watt adapter. For my laptop there are 2 different adapters available, a 65 watt and a 90 watt version, so there could be a difference in smart pin signal voltage to indicate power rating. I converted the adapter I had with this cicuit and it works perfectly so far.

Hope this helps. On a 65 watt adapter, the center pin measures 13,5 volts whereas the inner ring has 19,5 Volts. I will solder a 2,2K resistor in series with a 1k resistor between ground and 19,5 volts, in order to have about 13 volts in the middle for the sensing pin.
