Hp smart ac adapter (power supply)

what is the difference between the ac smart adapter 90w-19.5v and 65w-19.5v?
if i use 65w-19.5v ac adapter instead of 90w-19.5v ac adapter , will it create any harm to my laptop or laptop battery..?

IF your notebook was delivered with the 90Watt unit and you switch to a 65 watt unit, you may find that you start seeing warnings popup onscreen that caution you that the power supply is no providing enough charging capacity.
It won't hurt the notebook at all, but it is not good for the main battery.
The warning means that the battery is likely to not be fully charged by the 65 Watt power adapter. If your battery does not get fully charged, its service life may not be as long as expected. The main battery is warranteed to one year. With most notebooks, owners get two or more years of use from a battery. That is only if the battery was charged properly.

Smart ac adapter power output is too low for this computer on business notebook 6830s

Hallo,
Sometimes he is charging, sometimes he isn't.
I think it's a bad contact between the plug of the power adapter and connector on the motherboard.
Can I do something to improve the contact ?
thanks

That sounds as if that could be the case. Is the power adapter an original HP or is it an aftermarket brand?
If your notebook was delivered with a 65 Watt Power adapter the it is recommended that you replace it with an identical power adapter. Don't try to second guess the engineers who designed the notebook.

I believe it is an original power supply; the model number is noted in my original post. I really would like to agree with you about second-guessing the engineers, but I have seen too many poorly designed systems, including one in particular from HP.
At my last job, our CTO was an HP fanatic, and owned the largest and most powerful HP notebook at the time. I helped him to order a docking station for it based upon the HP compatibility list. When the docking station was connected, he encountered numerous strange power-related problems, and especially had problems with USB devices connected to the docking station ports.
It turned out after a bit of experimentation that the power supply that came with the docking station was inadequate to power the set-up, and using a larger supply completely resolved the issue.
However in my case it does appear this might be a dead or counterfeit supply. I will test it on my colleague's notebook, since it is identical except that he is running Windows (SP)7. I will update you with my findings. Thanks for your help.
Cheers,

Will the MBA Magsafe adapter/power supply work on an MBP?

Similar, but inverse question to this thread:http://discussions.apple.com/thread.jspa?messageID=6167022
From looking at several high res photos online, I can see that the MBA angled plug may be physically identical to that of the MB and MBP. So, mechanically it's all good. What about electrically?
I don't really care about needing to charge the battery at the same rate as the 85w supply. I just want something smaller for use during class (3-4 hours); I usually charge my Macbook Pro overnight anyway (or keep it plugged in).
Thoughts? I suppose I'll have to go to an Apple Store with my 'Pro and figure it out in person otherwise.

I'd be VERY wary of doing this. No problem using an MBP charger (with its higher possible capacity ) on the MBA, but using a lower capacity power adaptor might result in overheating and consequent damage to the adaptor, with the further slight possibility of shorting resulting in the high voltage side making its way to your MBP , with disasterous results .
Pulling out the battery when using the MBA adaptor might let you just about get away with running it safely, but I personally wouldn't risk it. I don't even like to use our 60W MacBook chargers on the MBP.
(I see in the other thread that some people are suggesting that the 85W charger might "overpower" the other computers. As ricktoronto has suggested there, this simply isn't so. The excess ability simply won't be used.
Using a low capacity charger / supply, like the MBA one, in a situation of high demand , on the other hand, can result in real problems, Overload can result in internal component failure or fire in the power supply. My bet is that Apple products will be pretty well protected against such things though).

Because the XP597A3 (actually any of these product numbers; XP597AA, XP597A3, XP597AS) is a HP 2011x 20" LCD/LED widescreen monitor. The OP was looking for an A/C adapter power supply for the HP 2711x 27" LCD/LED widescreen monitor, which is product # XP600AA or XP600A3. The adapter power supply I linked to, is the correct part for the 2711x monitor.... that is why not those other parts.

New power supply adapter for MD-100

Is there any place where I can get a new power supply adapter (or a new power supply) for my Nokia MD-100 speaker? I have a UK adapter now, which was inlcuded, but I want one for swedish sockets instead. I have an "external" adapter now, but I hoping I can get a proper adapter which fits the power supply.
Thanks.
Regards,
Joakim.

Hi Joakim,
Do you have the original UK charger for the Nokia PowerUp? If it's the one with the removable pins would you sell me the UK pins? And perhaps someone else has the Swedish clip, I've got a spare USA one.

SBS 380 power supply adapter

Hi, I hope someone have SBS 380 speaker system.
Can anyone tell me the output specifications for ?What is your AC adapter model number?My AC adapter is 2V 2.9A output (model#MAG20290THG) but the manual indicates 10V 1.2 A !!...what is wrong?I bought this speaker system yesterday. It was the last one and the salesman had to pack the content because it was in shop window. I think he mistook the power supply adaptper of another Creative speaker system, not SBS 380 !!The store is too far and I can't come back. In order to prevent damage, I have not yet used my SBS 380.My power supply adapter is correct?Can I turn on my SBS 380? What do you think?Thanks in advance to all.byezizu76

I would go with what's listed on the manual... If I were you, I woudl return to the store and ask the salesman properly...and have if test it on the spot...

Laptop power supply "Smart Pin" ?

Hi All,
I'm an electronic hobbyist and wanted to use a surplus HP laptop power supply as a power source
for my experiments. It is a large 'brick' rated at 18.5VDC @ 6.5AMPS, I think (sorry I'm at
work). When I cut off the DC plug I was surprised to find a COAX type cable with 2 shields and
a center conductor. After a little surfing I 'assumed' that the third wire is the center
conductor, or the smart pin. Cannot seem to find how the "smart pin" works. Anyone know of a
link as to how this works so I can be "smart" about using this power supply? All I'm looking
for is some nice, regulated DC.
Buy the way, I own 3 HP laptops and administer hundreds of HP servers at work. Wouldn't buy
anything else!
Thanks...

Hello friend, ignore those websites just cut your hp charger, u will see 3 wires which are the first layer, second and third. Cut off the third layer to prevent shunting cause it almost damage my laptop. Connect your positive to the second layer and negative to the first layer and that solves the problem. Can also be used on dell laptop chargers too. Tested and confirmed. Don't forget to cut of the third layer first. Kudos

ASUS U81A Power Supply- Extra Adapter

Hi Everyone
So i just ordered a W540 as my work PC too swap out my old Dell latitude.
My company is trasferring from Dell to lenovo setups in all the offices.
We move arround with our laptops so we have a lot of extra power supplys from Dell (19.5 V 3.34A with round plugs).
My question is, will we be able to use an adapter like this one (http://www.ebay.com/itm/2PCS-New-Power-converter-Cable-Adapter-For-Lenovo-ThinkPad-Carbon-0B47046-/3...) to power our laptops instead of buying loads of new power supplies?
Best Regards

No. That power supply will supply 65 W at the most, which is nowhere near the amount of power required for the W540. You could try to rig it to work on an X240, which takes about that much power, but a W540 requires a 170 W supply due to its power hungry CPU and GPU.

Connecting the NI1744 Smart Camera and PS-15 power supply

Hi,
I have a NI1744 smart camera and a PS-15 power supply. Firstly is it possible to use this to power the camera (it's my understanding that it can)? Assuming that it can be, is this all I need along with the 15 pin D-sub pigtail cable and ethernet cable to connect and power it?
Also, is it possible to cut a D-sub cable I currently have to make a pigtail cable, or should the NI 951x be used?
Thanks

Hi,
Yes you can!
Your power supply is suitable for the smart cam. Use a D-sub 15 connector and wire +24v to pin N°5 common is pin N°15.

When an iPod is changing, Is its power supplied by the adapter or by the battery?

When an iPod is changing, Is its power supplied by the adapter or by the battery?

The power is always supplied by the battery, just the charger supplies power to the battery faster than the ipod uses it.

All of the A1181 polycarbonate MacBooks use the A1184 60W MagSafe power supply/charger and the A1185 battery. These are the Apple part numbers. Other manufacturers make equivalent replacement products, but the quality may not be acceptable.

Power supply/adapter for Motorola ONT1000GI4

I fell for the three service package when getting FiOS initially. It turned out I didn't use the phone at all and I haven't watched TV in months. I digress, during the install, I noticed the tech installing the battery which, according to him was to facilitate phone calls during power outages.
The battery backup unit started beeping periodically the past few weeks indicating it needs to be replaced (though supposedly, it lasts 5 years and I've had it for just over one.) I decided to disconnect it altogether which is when I realized that the ONT is powered directly by the unit with some proprietary connector that looks similar to an S-video cable.
I would like to purchase a standalone power adapter/cable to power it via wall adapter instead of having to use the big battery which serves no purpose to me aside from taking up space and being an eyesore. Unfortunately, I've been unable to find much info on the ONT model to help me in my search. Also, there's no power information on the ONT indicating the voltage and amps required.
Anyone have any ideas? Thanks in advance.
P/N is 567004-003-00
FA P/N (not sure what this is, but it's on the unit as well) is 573796-003-00

You cannot easily replace the power supply / battery unit ("BBU"). The ONT communicates with it to obtain status on power and battery. It's more than just supplying the correct voltage.
You have several options to deal with the low battery:
Remove the current battery and press the battery silence button.
Re-install the current battery and see if that turns off the warning beep.
Buy a new battery. Online prices are very good.
Earplugs.
Note that if you have a battery, the internet will stay up for a minute or two during power outages. If you want longer run time, you need to supply your own UPS.
Good Luck.

Unibody adapter can transfer power supply neutral voltage

I hope this topic has not been mentioned before.
I have been using my unibody with the supplied and noticed that in some countries I get a tingle when I touch the computer. This is because the supply neutral carries some voltage. Even 5 volts (on a 240V) supply can cause a tingle when the body is touched. By the way, this is not a problem with UK power supplies.
I am considering purchasing an isolating transformer. Has anyone else come across the problem?
I overcome it by using the computer only when on batteries. However, I do worry if a power supply neutral is not properly earthed you could get a shock from the unibody.
I wonder of apple has an alternative power supply with an isolating transformer, other that the switching power supply as supplied.
Unfortunately this problem is specific to metal bodies only.

Hello HantuUK, and welcome to the boards.
AS long as you use the power adaptor with the three prong earthed cord rather than the two prong duckhead adaptor the problem does not occur unless the power source that you are plugging into is improperly earthed.
Poor earthing can, of course, be an issue in some countries, especially in remote areas and older buildings.
I've run into the issue myself in some remote Australian areas.
There have been quite a few threads about it over the years, often with strong debate about the actual cause. The problem has been around for a long time. I first ran into it with my old aluminium Powerbook 867MHz 12".

Power supply fan dead - help? (400mhz AGP G4)

Hello!
Unfortunately, my PowerMac G4, a 400mhz, AGP Sawtooth model, has a dead fan.
Over the last few weeks, I've noticed that my G4 has been running quite hot. I figured it was due to the hot dorm room that it's being used in. Then, I noticed that when it booted up, it would occasionally make a vibrating, or rattling noise - I figured the fan was wobbling. Since air was comming out of the fan opening at the top, I didn't worry about it.
Today, I used the "Temperature Monitor" widget to check the temperature of my SMART Hard drive (the G4 itself is not sensed). It was 133 degrees!!! This is the bay on the back-right, just under the CPU fan. I looked at the fan again - not much airflow. I pulled out a flashlight and pointed it in, and the Fan that's inside the power supply unit is dead.
So, how can I fix it? It's far far too hot, so it's not usable until I can cool it off. The first idea I had was to take a particularly powerful desk fan, and make a paper "tube" that connects both to the G4 and back of the fan - so it'll pull the hot air out. Needless to say, this is not a good log-term plan as it's easy to fall apart and will have leaks, but it works for now. I realize you can buy power supplies, but for ~$100, it's far too much for the old G4.
Second idea: The fan is inside the "non-user servicable" power supply, but it's also next to the back of the G4 - right inside what appears to be a panel that holds the power supply in. At the very least, I'd like to make sure that the cable is attached and not loose, but I have to open the back. Is that possible or safe? If so, can I replace the fan?
My third idea was to attach an extra fan to the inside of the G4, on the outside of the power supply - pushing in. Unfortunately, the IDE cable from the DVD drive is in the way, and there's not much room for a fan. Plus, there's no fan power supply. Is it possible to convert an ATA power plug (there are 7!) to a fan-power supply? I'd require a small circuit and a lot of resistors, obviously! If so, what would I need to do to convert it?
Thanks a bunch,
-Dan
15" 1.67 Powerbook G4 (Jan 2005), 400 mhz AGP Sawtooth G4 Mac OS X (10.4.8) 4G Clickwheel and 5G Vid iPods, 2G iPod shuffle

Thanks!
Interesting, this "Piggy back power adapter" will allow me to plug the fan into one of the ATA/IDE cables? Or do you mean the extra port on the power supply? (it has one plug for the outlet>G4, then another to support something like a monitor or similar) The G4 has a DVD burner, but no ZIP drive, so this is quite do-able if it uses the ATA power.
When you say "lower rear", do you mean at the bottom? Below the power supply, to the right of the PCI slots? If so, this is the inflow for the CPU fan! I can understand mounting it outside the current outflow-vent for the dead power supply fan, although I'm not sure the best way to proceed with attaching the fan.
Another question: what tools and supplies will I need? I may need to remove the plastic cover on the back of the G4 - the one that is outside the power supply - as there's a gap between the gray plastic and metal chassis that lets air from outside the machine come in. The screws for this cover use a funky, hexagonal screwdriver. If I need to take this cover off, what kind of screwdriver will I need? Also, should the fan not include screws/etc, what's the best method to attach it? Glue?
Secondly, to cut a hole in the G4, will I need some variety of drill? I don't have one, so i'll have to borrow one... Since there's nothing in the ZIP slot, I can run a cable out through here (assuming it's long enough), and make a new bezel to keep the airflow inside intact.
Ah! One other (somewhat related) question: my USB 2 card includes a power adapter, for use when several un-powered devices (flash drives) are attached. It works just fine with a flash drive and a small media reader, but it's slow to sense the drives - I think it's low on power. Unfortunately, this power plug uses the same variety of plug as the floppy disk drives found on many win-boxes - of which the G4 possesses none. Is there an adapter/cable for this purpose?
Thanks, this is a HUGE help, I appreciate it.

HP Power supply PPP012H-S / 384020-002 compatibility with Pavilion DV5000 (DV5196EA) notebook?

I have a Pavilion DV5000 (specifically, DV5196EA) notebook where I need to replace its original power supply.
I also have an HP power supply from some other notebook (I don't recall what kind) which shows the same output specifications (19V, slightly higher wattage than the original), but it has the wrong physical plug on the end.
The original power supply has a tip similar to this:
The other power supply that I have, from some other notebook, has a larger tip which looks like this:
(Apparent sizes are incorrect in the in-line image uploads above -- the actual tip on the PPP012H-S power supply is about twice as wide as the tip on the original power supply of my DV5000 series notebook).
I tested both power supplies using a multi-meter, and confirmed that the power output of both is 19VDC.
I clipped off the current large barrel end from the PPP012H-S power supply and stripped the wires, intending to solder on a common replacement tip which matches that of the original power supply, but I found a surprise when I stripped the wires:
There are three conductors inside the sheath of the PPP012H-S power supply. An outer heavy braided shell just inside the outermost rubber-plastic insulating coating, inside which is another smaller gauge rubber-plastic insulating coating, with innermost two more normal insulated stranded wires - one in white and the other in blue.
I had assumed that the outer braided shell was either ground or EM shielding, but in fact it's a conductor. Using the multi-meter I found a 19VDC differential between that outer braided shell and EITHER the inner white or the inner blue wire.
And one more weird thing. Switching the multi-meter now to resistance mode, I had expected (given the voltage detection above) that the large thin barrel of the PPP012H-S adapter's tip would share one electric potential both outside and inside the barrel, with the very find centre pin being the other pole ... but no. There are apparently three conductive surfaces; the outside of the barrel, the inside of the barrel, and the centre pin, none of which are connected to each other.
Not wanting to guess that the power supply might like the idea of shorting the white and blue leads together, and observing (I think?!) that the tip of the original power supply has only two conductive surfaces, and therefore guessing that even if the PPP012H-S' intended notebook might care about whether it was being fed from white or blue the DV5000 would not care, I insulated off the white lead and soldered the outer braided shell and the blue lead to the new tip. Multi-meter again confirms a steady 19VDC in the correct polarity.
But when plugged in to the DV5196EA notebook, the notebook does not detect any power being supplied.
Crap.
Is there some kind of electronics smarts in the PPP012H-S power supply which makes it detect and refuse to supply power to the DV5196EA notebook? Or some not-quite-so-smarts but which still really wanted me to use the white lead instead of the blue lead? .. or is even the simpler tip on the original adapter (which I believe has only two conductive surfaces) actually a little less simple than I think and it does have three surfaces and I do need to attach all three of the conductors from the PPP012H-S to (Something, where?) on the replacement tip?
Yes, a bit of work to go through to avoid spending $50 on a new power supply, but I've got the parts and I thought I had the smarts and I enjoy the challenge (up to a point!)
Thanks for your help!
-Jay

can anyone tell me the pinout of a ppp012h-s power supply please?
