Toughbook 12V power adapter

Q: Toughbook 12V power adapter

I recently purchased a Del Latitude 7202 Toughbook.
At same time purchased 12V power adapter.
The adapter was shipped separately. SKU 469-4546. The power plug did not fit computer.
It is too fat. Spent 4 hours with tech support and they told me the wrong part was shipped.
They said they would send a replacement. 10 days later I get a package with an HDMI cable in it.
Call support back, was told they would just issue me a credit and I can purchase one online.
I was told I needed part. 450-AAYR. Web page for that part lists the 7202 as compatible.
It arrived yesterday. Still doesn't fit. I am returning it as well.
What is required to get the correct part?

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

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?

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.

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.

Third step was to have toughbook boot from LAN with cable connected to my notebook. I never said I was smart, but but at least my notebook didn't crash. I got this message:

Hello everyone. I have Panasonic cf-74CCBAXBM. I have no sound since I have upgraded my OS to Windows 8 so I try Windows 7 dance edition. I can't hear anything from my laptop speaker nor I put on earphones/speaker.

I tried uninstalling High Definition Audio Device trying to replace it by Realtel / Sigmatel and other drivers I can't remember but it always say, "it don't match my device". And the Windows kept on re-installing the HDA whenever I tried to reboot.

So I started looking for other drivers in Device Manager to see what might have the problem. Under System device > system speaker > properties it says:

Device Type: System Device
Manufacturer: Standard System Devices
Location: on Intel (R) 82801GBM (ICH7-M) LPC Interface Controller - 27B9

Device Status: No driver installed in this device.

That is what it also says on Programmable Interrupt Controller, System Timer, Intel (R) 82801 G (ICHM Family) SMBus Controller 27DA. I havn't check the other drivers but I think those are the problem. I tried to find them but I still have no luck. Please anyone help me.

I have several Panasonic Toughbook CF-27 laptops that originally came with Win95. I recently loaded NT 4.0 and attempted to install 10/100 Ethernet NICs, but haven't been able to get them to work. I've tried both a Xircom RealPort and a D-Link DFE-650. I've had a little more luck with the D-Link, but it still won't connect. I first tried it with no card services installed, and the card wasn't recognized. I then tried it with Card Executive 2.0 for NT (recommended by Panasonic for this model), and that recognizes the card and shows it as "available for use". When I use the diagnostic program that came with the NIC (which must be run through DOS) I get an error:

D-Link DFE-650 PC Card Client Driver v1.05
Card/Socket Service is not found.
Please install PC Card environment before use DFCD.EXE

Card Services are installed and seem to function properly - the type of card is shown in the correct socket, with the I/O port and IRQ information displayed (and there weren't any conflicts that I could find - neither the I/O nor the IRQ were in use by any other device).

I can ping myself, so the bindings appear to be ok. The DNS and WINS settings are correct, and I'm using a known good line to test the connection. When I turn the computer on, all three lights on the NIC connector light up (10/100, half/full, and Ln/Act) with Ln/Act occasionally flickering. When I try to connect to the domain these lights will remain lit for about 5 seconds, ... Read more

I have a panasonic toughbook CF-R3 and the problem I have is that sometimes it turns on and the times time not. The LED is on and when I push the power button it turns off and if I leave it in the bag a couple of days then it works fine but as soon as I turn off again it will need some days to be able to start again. Very bizzare! Does anyone have any idea.

A:Toughbook won't turn on sometimes

When you shut it off, do you close the lid?

If you do, next time don't and see =over a period of several days if it starts ok.

If it does, then a sticky micro-switch on the close-lid circuit is likely.

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.
Also, please click my DELL-username and write me a private conversation with the service tag and your contact details(Name and Email) for case records.

Hello aaronbaron,

Reseat the power adapter just means make sure the power adapter is plugged in good on the laptop and the wall outlet. I would try powering off the laptop, unplug the power cord, take the new battery out. Reinstall the new battery only and try to power on the computer. If that does not work plug in the power cord and power up with the new battery installed.

It's an hp 6720s 13 months old, XP Home, HP 65W power adapter.

Laptop running fine on battery only. Laptop runs fine when battery removed and power adapter is connected. Laptop does not run fine when battery and power adapter connected - 100% CPU.

Also, the charge indicator light no longer works and the power icon does not show that the battery is charging, although it is.

I've updated the BIOS, restored factory power settings and tested the power adapter during startup and have the same prob with the CPU usage.

What could cause the power adapter to use 100% CPU? Please let me know if you need more info, cheers.

A:Laptop power adapter uses 100% CPU

Is this an Adapter obtained from HP as a direct replacement for the proper adapter as shipped from HP with the laptop?

Hi Guys,

I was hoping someone could help me out finding a power adapter for an old set of Harman Kardon speakers I have. On the back of the speakers it says ac 15v 1.1A so I assume I need an adapter that matches those settings.

Can someone plz help me out finding one that will work and is as cheap as possible.

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 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 Precision 7510 updated with the latest Bios and drivers. Today my TB15 arrived. I haven't tested connecting a monitor to it yet only a network cable and USB 3.0 stick - this worked fine.
I also tried starting the laptop from the button on the TB15 which also works fine.
However on startup I receive an error message:
"Alert! You have attached an undersized 130W power adapter to you system, which is less than the recommended 180W power adapter" ... message carries on a bit.
Now the thing is both the TB15 power adapter and 7510 power adapter are the same (identical part number) and  are shown to be 180W output.

I am planning on making this project myself but first I have one question. Here is the project I will be making:

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.

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.

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?

If not, what are the alternatives? New PSU? Different GFX card?

The Yoga 3 Pro power adapter looks like a normal USB brick, and the cord looks like USB, except with a kink in the connector at the Yoga 3 Pro end. Can I charge my phone or tablet with it?

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 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.

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.

I realized that the stock charger seems underpowered, at least the one I received with this unit, which I bought used "like new" on Amazon for $850. I was somewhat let down initially upon testing the system for performance, then I found it would double it's performance when on battery power. This indicated to me that the unit was able to draw more current from the battery than when plugged in. Having an understanding of power requirements and electronics, I realized the unit may benefit from using a higher wattage power supply. I bought this baby intending to run "Project C.A.R.S." which is purportedly the most advanced racing sim ever made, with awesome graphics blowing away all current Xbox/PS4 etc. platforms. I found I could run it reasonably well on battery power with the system dialed in using Intel Extreme and PrecisionX for pushing the CPU & GPU to their comfortable limits. Also something I've learned over the years is it's generally best to use the true HP drivers for GPU, manufacturers tend to custom tweak a given driver for their specififc model giving it the best performance even though the revision is never near the most current. Now, the big reveal... I decided t take a chance and buy a used 230watt HP power supply for $38 amazon, then splice the cord so the power adapter would fit this model. I went from not being able to charge while plug... Read more

I have recently rescued a 15 inch viewsonic lcd monitor from being trashed at my work. I did not find the ac adapter for it and would like to use one of my old PSU's to run it. Since the power requirements for the monitor are 12.0V 3Amp, I assume I can just use the 12.0V rail on a standard PSU and attach a tip to it (which I have from a broken universal wall-wort). Will this work? Can't I use any power supply/ac adapter that is capable of supplying 3Amps or more of current as long as it is 12.0V? Thanks in advance.

BTW...I did try a duracell battery charger ac adapter that ran at 12.0V and 2.5A for a short period (as to not damage the ac adapter) and found that the monitor works fine (just has a little fraying on the VGA cable). So I know it is worth converting a supply for it.

A:Use a Comp Power Supply as an ac adapter?

A 12-volt supply capable of 3 amps or more is all you need. Just be sure the polarity is right.

I have a 12-port network switch in my shop that's been running off a 5-volt leg of an old computer power supply for several years. At the time, the manufacturer wanted as much for the power supply as I paid for the entire switch and power supply the year before. Old computer power supplies are plentiful around here.

Seeing as my PSU is limited in the cable department i had to purchase a 4 pin to 8 pin adapter to power my PC.

Hi all. I'm semi-reliably informed that my main board is dead.

If my HD survived whatever traumatic event caused the above, I'd like to attempt to salvage some of the data from it. It's a Maxtor DiamondMax Plus 9 80GB ATA/133, 3.5 series.

So far, Ive found this adapter which seems like what I'll need to connect the HD to a laptop via USB in order for it to show up as a removable drive from which I can pull files. Note: I don't want to open the laptop & connect directly vice the DVDRW as it's still under warranty.

So, my question is ... what's the power source on the adapter for? Is it in case you want the connected drive to function as a working drive as opposed to just a storage device?

(sorry, no doubt this is a really dumb one, hardware's just not my thing )

Any advice on this specifically, or any general comments on the likelihood of success of this operation, gratefully received. TIA,

I just bought a wireless highpower adapter since my room is so far away from my router/modem.

I used the software that came along with my adapter to scan the surrounding network, but it didn't pick up on my net work no matter how many time I scan it. But it does pick up a few of my neighbors' wifi signal.

But I could connect completely fine with my laptop itself.

Need a power adapter for the MacBook Air 2010 with the "T" style connecter on the end.... the factory supplied charger with the "L" connecter if turned away from blocking ports doesn't charge the laptop and if I turn it to block the USB and Headphone jack it charge perfect.... does it on EVERY SINGLE CHARGER I try so it can't be the adapter but the Laptop being picky on which way the charger is turnedI know higher watt chargers will work and can be suggested (confirmed to work by Apple).....

A:Power Adapter for MacBook Air 2010

I'd check to see if there is a dirty connection. Clean with rubbing alcohol and q-tip if there is any gunk on contacts. If the connection in the MacBook is damaged then it should probably be serviced if even worth investing money into a 5 year old MacBook.As for the power cords, lots of complaints about them as junk.
