Power adapter compatibility

Q: Power adapter compatibility

I have a Toshiba Satellite A215-S4807. I need a new power adapter. (there appears to be a loose connection in it somewhere. It only works when I king the wire a certain way.

This adapter from Targus says that it is compatible but it is only 70W where the original was 120W.

Would the differnce in wattage present a problem in trying to use this adapter?

Thanks very much for your help.

I recently damaged the slim tip of my AC adapter which is 65W and 20V (model number: ADLX65NCC2A). Would any slim tip adapter that is 65W and 20V be compatible with my laptop (Thinkpad yoga 460 bestbuy version)?

I have an extra older Vaio AC power supply, 19.5V, 3amps.

Can this be used with a Vaio that's AC power supply is 19.5V, 4.7amps? Plug polarity is the same.

A:AC adapter compatibility

No, the laptop needs 4.7 amps of current and the adaptor you want to use can only supply 3 amps. You will need to find one that is 4.7 amps or above.

Underneath the laptop should say what amps are needed, if that says 3 or less, then the old adaptor would be fine, if not then don't even btoher trying it as it could break something.

I have a new Toshiba Satellite 1005-S157. Want to use my old auto air adapter, but even their "TECH SUPPORT" will not give me a definitive answer on compatibility.

I THINK it will be OK, but I fried one hard drive a few years ago using the wrong Targus Universal tip. So I am a little paranoid.

What I have is this computer that says
DC 19V-----3.16A

And the Mobility auto air adapter that says

The computer I previously used it successfully with was a KDS Valiant 6380
which said
DCV 19-3.42A

Would appreciate anyone who knows about these things giving me a straight answer. Thanks in advance.

Hey, i'm just trying to find an answer to something. I just download the windows vista upgarde advisor to see if my computer could run vista when it comes out and the only thing it said wasn't up to par was that my network adapter will not work or be supported. And this makes sense, because when i downloaded the vista beta a couple months ago, i could get my internet to work. I just didn't think it was because it wasn't compatible.

Is this true? Doesn't anyone have a link or some info about unsupported devices? i have a CNET PRO200WL PCI Fast Ethernet Adapter. Will i need, of all things to upgrade, a new network adapter to run vista? :suspiciou

A:Network adapter - Windows Vista compatibility

The Cnet site is the first place you will here about Vista compatibility for their products.

If there is a problem with that card and Vista,it would be public pretty soon.

In the worst case scenario,a new card is only $10.

The tips I got with this Kensington 33197 power adapter have numbers stenciled on them like N3, N5, N19, etc. The tips sold on their web site make no mention of the "N" numbers and have numbers like K20059, K20050, etc. and there is no cross reference.

You can also see a complete reference for "N" numbers to all the laptops they support at the above link. Again, no mention of the numbers Kensington uses on their site.

I need a cross reference for these kinds of numbers.

Kensington referred me to their telephone tech support; but, there is a language or cultural barrier that prevents their understanding what I need.

Does anyone know of such a reference?

My laptop will no longer turn on.  When the AC adapter is plugged in, the LED light is white indicating power is arriving at the laptop. However, nothing happens when I push the power button. Troubleshooting steps I have completed already include: Hard reset (several times including after each step below)Tried starting without the batteryRemoved all removable components and reseated themRemoved all removable components as well as bottom cover. Cleaned with compressed air. Put everything back.Nothing appears wrong and nothing happened between the last time it turned on and this time that I am aware of. The laptop is out of warranty, and I am pretty handy with computers. Is there anything that can be suggested short of a hardware replacement that would help get this resolved? TIA

This is a common problem (I see lots of posts)
The problem source is the [Dell] AC adapter.  PA-21 Family, 65W, P/N: NX061.  It is made in China.
I have an XPS M1330.  Using Dell after warranty service, replaced the Mother Board twice, replaced the battery twice, replaced the AC adapter twice - not fixing it.
Turns out the power warning message is very informative.  It states "Please connect a Dell 65W AC adapter or greater for best system performance".  So, I plugged in my Dell 95W adapter - WOW Problem Solved.
A lab test of my new Dell 65W AC adapter shows it to be 64.6 watts.  If this unit gets hot (like after several hours of use), it may not put out the full 65 watts - the system may not recognize the adapter, it may power the system ok, but won't charge the battery.
These units burn out after only a few months of use. Their cables are too fragile. If Dell's or their supplier's Quality Control can't produce a reliable 65W product - I found seveal "Made In USA" universal adapters.

A:AC Adapter - Alert - "AC power adapter wattage and type cannot be determined"

Well my solution was simple.
I just removed the battery pack and powered up my notebook. Then I turned off the notebook replaced the battery pack and VOILA. The error message was gone.

Possibly a noob question, but please help if you know about this.

When buying a PSU I know I need the right Wattage for compatibility with my components. But is it important (or not) to also know the Amps and Volts and/or size the cables have that will go into the MOBO? Does this have anything to do with ATX/EPS? If so, what is ATX/EPS? I am cluless, please help me understand WHAT is important to know and what isn't. Thank you

A:Power Supply - Compatibility

Voltages are standard. Amps matter but mostly on the +12 volt rail(s), that's where most components draw from. Any quality power supply will have the majority of its power on the +12volt rails.

EPS is an extension of ATX adding extra power, stability, and connectors for higher end systems, they can be used in place of regular ATX power supplies. I think most good ones these days are EPS.

Hey guys,

My motherboard has recently blown and I've had to replace it. My only issue is that it has a different internal power source to my former motherboard and I'm not sure if I can utilise my old power supply with it. I've included pictures of the motherboard connection (the blue one) and the power supply connection. Power supply connection is for a larger connection but it works perfectly with the motherboard, except it is inserted into 4 slots rather than 8.

Is this safe? It seems to be working fine.

IMO, 40GB is way too small for the system drive. You'd be constantly babysitting it, moving files, and everything you do would have to be retargeted before starting a project. Windows 7 64 bit would use half of that space just for itself.

My experience suggests its best to have all applications of the same version, so Office 2003 pro would be the way to go.

If its not too late, you could try to get OEM version with the hard drive as the qualifying "hardware".

i want a graphics card along the lines of ATI X1900. it needs a 400W+ PSU, my system has a 250W PSU.

if i install a 400W PSU will it effect the other components in any way, eg... blow the motherboard? fry the HDD?

searched already for an answer but could find a specify yes or no... cheers guys

A:Power supply and mother board compatibility

Most likely no. There are some older Dell systems that had a proprietary power supply where the pins were switched around so that only a Dell PSU could be used.

As far as pure wattage goes, have no fear. 1000w power supplies are just as safe if not safer than that 200w in the current system.

Really, if your planning on investing in such a nice graphics card, you might as well put just a little more into the PSU as well, maybe a 450w or 500w.

Hi I am trying to build a cheap cost effective PC for playing World of Warcraft and other mmos and rts games.

Right now I am using a complete pile of crap. A compaq presario s4020wm with windows xp. It has an amd athlon xp 2000+ and only 352mb ram.

What I have found so far, but my ears are definitely open to suggestions:

AMD Athlon 64 X2 6000+ Windsor 3.0GHz Socket AM2 125W Dual-Core Processor Model ADX6000IAA6CZ - OEM

Ram: 4gb (2x 2gb 240 pin ddr2 800mhz)
Hd: 500gb sata
Os: win xp sp3

I chose this motherboard because of its cheap price for what you get with the graphics card for now, and being able to add a pci-e 16x 2.0 card on later.

The mobo is micro atx and says power pin 24 pin.
When choosing the case will anything that says ATX be fine?
Since micro atx is just atx but smaller?

Since the motherboard says 24 power pin the case MUST say it has a 20+4 power supply unit?

Some cases with a power supply do not say how many pin the psu is at all. Do I assume those are just 20 pin?
For example this one here, will work or not because it does not say if it is 24 pin and my motherboard directly says it needs 24.

I have an ASUS M4AGTD PRO, and it requires EATX power.
However, my power supply only has ATX and EPS power (Both 12v, as required by my motherboard).

I at first tried using the EPS cable, which worked. Sorta.
It wouldn't boot, but I can't exactly say that it was at the fault of the PSU just yet, as I had incompatible RAM (wasn't listed under the QVL) and CPU (wasn't listed under the supported processors), both of which are being replaced shortly.

It fit perfectly into place, as well. Which I can't exactly say for the other cable....

The ATX cable didn't work, but it's possible that I didn't place the 2x2 pins in their correct positions, as I've heard mention that it's still possible to power the motherboard with ATX when it requires EATX.

I'm troubleshooting several other things on my new build, so I can't exactly limit my issue to my power supply.

But I guess what I'm asking is whether or not my PSU is compatible with my motherboard.

If it is, then I can eliminate it from my list of suspects.

I'm getting a GeForce 8400 gs, and a 380W power supply.

The graphics card says "Minimum recommended power supply with +12 Volt current rating of 18 Amp Amps." I looked over the power supply specs, and none of the 12v outputs have an amp rating of 18. I read somewhere though that you have to combine the rails to add up to the amp rating? I assume that's for high end graphics cards, where you have to plug the psu directly into the card. I don't know what a rail is, I don't know how it would work for this graphics card, since it doesn't seem to require the psu to plug into it directly, Iz confoosed.

I am basically clueless when it comes to power supplies, so can someone please educate me in this, and PLEASE be mindful of how you explain it because like I said, I'm almost clueless about this stuff. Taking a couple more minutes to throughly explain this to me so I understand it well, won't kill you.

I don't want to sound rude when I say this, but it annoys me when people do this to me. I honestly don't care what graphics card or power supply you have, if it's better than mine and you think I should get it. I am well aware that there are graphics cards, and power supplies, that are WAY better than the ones I chose. I chose these pieces of hardware because of my budget.

A:Question about power supply compatibility with graphics card

It may be the way the specs are written on your PS... but
The graphics card does care what the output is... more than the motherboard or other component does...
A cheap power supply from 2005 or before had a better chance of not supplying the minimum power.... Now you can see all these specs for a quality power supply when you look at the descriptive information on the power supply section of Newegg, Directron, ZipZoomFly,, and many others... but only in the past year or two has it all been published.

For the last two weeks, every time I start my Dell INSPIRON E1705 while using the power supply I am greeted with the following message. "The AC power adapter type cannot be determined. Your system will operate slower and the battery will not charge. Please connect a Dell 90W AC adapter or higher for best system operation". I press the F1 Key and everything works fine. I've read about this on other websites and most say it's a design flaw in the power supply after the cord has been properly wound around the supply as designed. Apparently a few of the cords internal wire strands become broken and cause this message. My computer is from June 2006 and shouldn't be having this issue so early...or ever. This seems like a flaw that should have created some type of manufacturers recall since so many people are having this issue. I'm of course out of warranty, will Dell replace this free of charge?

A:Power Supply - "The AC power adapter type cannot be determined....."

You are correct, the failure is due toloss of the power supply ID signal. Sometimes this happens because of strain on the plug, which breaks the signal wire. Some even are so severe that the insulation breaks away from the plug; this is due to rough handling. The other cause is one or more of the power socket solder connections to the system board become broken. This also is related to severe handling. I have seen one case where all three power connections and three of four mechanical connections were disconnected. If the power supply is bad, a replacement will cure the problem. If not, then the socket is bad, and this will require a system board replacement. If you are experienced, you can try to resolder the connections. I am experienced and was not able to get my daughter's E6000 to work by resoldered. More recent Dells are using a replacable power connection board which is a much cheaper repair.

Hello aaronbaron,

Reseat the power adapter just means make sure the power adapter is plugged in good on the laptop and the wall outlet.

Can I use 45 Watt adapter for dell inspiron 15 5559?? I got the adapter along with the laptop when I bought it. But a warning is displayed on screen prompting me to use 65 Watt adapter... If so why 65 Watt adapter wasn't given with the laptop instead of 45 Watt?

A:Power adapter

The system is designed to support both 45W and 65W adapters - see the specifications here -
When you plug in the adapter to the system, does the adapter stay firm or does it fall off easily? Is the adapter frayed? Could you test with another power adapter if possible?
Restart the system and press f2 key to enter BIOS - check the adapter status in BIOS with and without the adapter plugged in. Also, wiggle the adapter cable at the end and see if the status changes in BIOS at any point.
Restart the system and press f12 key on startup - choose diagnostics. Let it run the diags and if you encounter any errors - make a note of the complete error and report the same to us.These are onboard diagnostics and they might possible pick some error if the hardware is not functional.

The replacement adapters for my model (dv6000) list the power output as 18.5 volts 3.5 amps 65 watts.

Will an adapter that was higher voltage amps and wattage work for my laptop that requires less??? This is assuming that the connector is the same which I'm not sure of.

Hi everyone.

I know that this is not really entirely related to a Windows 7 computer and especially to these forums, but I really need some advice on this and it would be great if anyone who has experience in voltage, amps and safety for laptop power adapters would be perfect.

My friend has just traveled down to my house for a week but has foolishly forgot his plug for the power socket on his power adapter. He uses this for his computer. Again unrelated becuase it is an Apple 45W MagSafe2 adapter.

So I was wondering if he could simply use a cord like this one below to plug into the adapter?
The black cord is 2.5A 250V~

The adapter is 100-240V~ 1A

These are both for input.

Any help would be greatly appreciated .

A:Power Adapter Problem

That white 'thing' appears to be for an Apple Macintosh MacBook/MacBook Pro [I have a MacBook Pro] and you might not be able use the black cord due to fit, the V-shaped notch in the black plug would have to let it be inserted. But it probably won't hurt to try as it's still a 110/120Volt source.

The MacBook power adapter also came with a piece that replaced that cord and has the prongs to plug directly into a wall socket/extension cord, maybe it's in his Notebook bag.

I have a compaq nx6325 lap top, which will not turn on at all. The power adapter
shows 18V between the inner and outer ring and appears ok, led on etc.But what's the tiny center connector for in the plug? Should there be a voltage on it to earth, or to the ring connectors?Finally,should I be able to power-up the lap-top with the power adapter plugged in, and the battery out?

A:Power adapter center pin

Sounds like the Centre pin has broken away and lodged itself in the plug. I cannot tell you which is positive and which is negative with regards to the rings on the plug. Because different Manufacturers use different combinations and with that different Voltages too. Generally speaking the outside piece is the male end and the receiving plug is the female -go figure-
Hope this link works you can see what I am mentioning, obviously this is not your cable but for the example of male to female ends the description matches the pictures ( not the 'Y' cord on the link )

Is there a maximum length for the dc cord? In other words why do they locate the adapter 1/2 way down the cord instead of closer to the outlet.

Is the small cylinder around the cord about 3" before it enters the laptop some sort of choke/filter?

I have a 90w power adapter from an older notebook that will work with my HP DV5-1015nr. 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. The problem I have is that the older power brick has two wires: core wire (+) and shield (-), and the newer power adapter has three wires: shield that is connected to the core of tip (+), black that is connected to outer part of cylindrical shaft that must be the ground, and white connected to inner part of cylindrical shaft (also negative?). So do the black and white wires on the newer adapter need to be soldered to the shield on the older one?   

A:Wiring for Power adapter?

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. Did you measure voltage and ploarity of all three connections with the brick plugged in? Tip is always + and ouside is always - on a HP, not sure what the third is, see if there is any voltage on it, It could also be some sort of sensor wire for the charging system on the mobo. Better to buy another adapter than smoke the motherboard on the lappy taking a chance. If you want to chance it just connect the two wires that are on the center and outside. Leave the 3rd odd one unconnected. probably can be found used for cheap.

Though I had posted this previously, but cannot find it anywhere!

Got an Altec Lansing Multimedia Computer Speaker System ACS41. Apparently they were used on a Gateway 2000 PC.
However, the power adapter was lost.
The speakers do not have any electrical specs on them regarding voltage, amps, and polarity.

Anyone have a similar set of speakers, or,
know of any way this type of info can be found out, in order to get the right power adapter for them. Do not care to fry them with an overkill. The speakers probably came with PCs running Windows 98SE, or Windows Millennium.

Prefer not to go to Radio Shack, they normally are rather expensive, and the people who own this do not want to go that route.

I have a 20 pin motherboard but the power supply I have available has a 24 pin connector. I've read that you can simply plug them together by offsetting the 24 pin one but so far I don't see that working at all (and 'never the twain shall meet', so to speak). I've found adapters but they all say something akin to

'allows you to connect your existing 20 pin power supply to your new 24-pin compatible motherboard'

You can use it the other way around, correct?



A:20 to 24 pin power supply adapter

Some mainboard connectors are 20+4 pins where the 4 pins unsnap from the 20 pins for use with boards with a 20 pin connector. If your power supply doesn't have that feature you would use an adapter such as this.

It says I need a 12V DC supply for powering the breadboard. When searching up for 12V DC supplies, I only get power supply's that plug into the wrong wall socket (I live in Australia).
Do I need to get something like the article suggests:

Or can I get something such as this:
If the first option is the only possibility, how do I get the plug to go into my wall socket?
Also, how do I get the other end plugged into the breadboard when the product just has a single plug on the end?

A:What type of power adapter do I need?

You can use the Ebay adaptor, the easiest way to get 2 wires is to get a socket that fits the plug, like this one :- and solder 2 wires to that socket.

The circuit at your link uses a 2 wire plug into the breadboard, you would have to get a similar plug OR you could push bare wires into the breadboard.

OR you could cut the plug off to reveal the 2 wires but they will probably be quite thin and may not connect well if pushed into the breadboard holes.

My neighbour was given a second-hand computer and asked for my help setting it up.

It is a Dell Optiplex 755 running Win7.

Currently installed graphics is NVidia Quadro FX 3500.

I looked up the service tag and this is not the original card (Original was ATI HD2400XT).

The issue I have is that the FX3500 is an 80W card, with the PCI-E slot having a max of 75W. On booting I get low power warnings from the NVidia card.

The card has a 6 pin PCI-E connection available for the additional power, but the PSU has no PCI-E power cable.

The only free power cables from the PSU are a couple of 15pin SATA cables. I have seen adapter cables for 15pin SATA to 6 pin PCI-E. Are these any good for my situation?

A:What's with the Yoga 3 Pro power adapter - it's a ...

Yes the Yoga 3 Pro power adapter is a USB charger too!

How does it work?

The special "fool proof" charging cord has two extra pins on the AC adapter end and two extra pins on the Yoga 3 Pro end. The extra pins only make a connection when the fool proof cord is plugged in to the Lenovo charger and the Yoga 3 Pro. When a regular USB cord is plugged into either the charger or the Yoga 3 Pro, it makes a regular USB connection.

Can I charge the Yoga 3 Pro with any USB charger?

No. The Yoga 3 Pro requires 2A at 20V, which is what the provided 40W Lenovo AC adapter supplies.

Can I charge a USB device with the Yoga 3 Pro AC adapter?

Absolutely. In addition to 2A at 20, the Yoga 3 Pro AC adapter supplies 2A at 5.2V (10.4W), enough to charge a phone or tablet. Works for iPad.

Where can I buy spare AC adapters and cords?

AC adapters with cords are sold in the accessories section of the Lenovo store.

Where do I find the part numbers for the AC adapter and cord?

Look for AC Adapters In the PDF Yoga 3 Pro Hardware Maintenance Manual.

What are the USB specs of the Yoga 3 charging port?

It's a USB 2.0 port. It provides enough power to charge an iPhone, but not enough to charge an iPad. If you want to charge an iPad, try the USB 3.0 port on the right of the Yoga 3 Pro.

I have a Inspiron 15 3541 touch screen and "misplaced" my power cord and adapter. I'm using a Dell adapter from a different computer, but when I turned on my laptop, I get a message requiring a system or admin password even before it boots up. Is this because of the different adapter? How many pins did my adapter have? What problems does a different adapter create?

A:Power adapter pins

The password that is showing up before your computer boots sounds like there is a BIOS password set on the computer.  Unfortunately if you don't remember that password then you are probably stuck.  You can probably go online and search and see if there is a way to reset BIOS on the laptop and get it to default and remove the password that is set on it.  If there is a hard drive password though then the only way to remove that if you forgot it is to install a new hard drive as the password will follow the drive, not the computer.
Your power supply should have only 1 pin.  Dell used the same adapter for their computers for a while, they come in different wattage though and if you use an adapter that is too low then it may not be able to charge the battery while you use it or at all.  If the plug fits and it is a Dell charger you should be okay to at least get the computer up and running.  If it is a low wattage charger and the setting is set in BIOS (usually is by default) you'll get a message from your computer telling you that the charger isn't powerful enough to charge the battery while in use.

I have a Toshiba Satellite laptop (circa 2003). I know my laptop battery has been drained for a while and I was almost solely relying on the AC adapter's juice to power my machine. Recently, I lost all power to the laptop. I thought perhaps my battery had finally had it so I bought a new battery. Well, then I couldn't charge my battery, so I bought a new AC adapter. I still have no juice. It looks like the AC adapter is working (the light is on it to show it's getting power) but it's not transferring that power to the machine.

I think it may be a bad connection between the adapter plug and the laptop. I don't know how involved of a fix this is.

Hi All, I am getting a very strange issue with my Lenovo SL 510. When i plug in charging while laptop is on it starts disconnecting power adapter every cople of seconds or some time is 5 second (no consistent behaviour).. i thought it could be my power adapter that is misbehaving. I removed battery and started laptop with ac adapter on. it worked fine no issues at all.  if i turn off laptop and put it under charging it get's fully charged and battery also lasts for couple of hours. so no issue in charging while laptop is turned off.. so that rules out possibility of issues with adapter. The issue is only with laptop  charging when it's turned on. it keeps disconnecting. it is really very annoying as get to hear beep sound Similar to hospital sound :-)

A:B590 - Power adapter, Use in New Zealand?

Welcome to the Lenovo Community !
According to the specifications listed on page #8 of your model's User Guide, your power adapter is a dual voltage adapter that will handle a voltage input of 100 to 240 Volts AC.  Since New Zealand's power standard is 230 volts,  all you will need is the plug adapter for the wall socket and you are good to go. 
Here is a link to the User Guide for your reference.......
