My dv7 is shocking me o.o

It does it more when it's plugged in.I'll accidentally touch the edge or get near the sides where the hdmi port is and it'll shock me. Once my hand was just resting on the left side of the keyboard and it slipped and it shocked me. -_- This happened with my older dv6 quad so i'm not really in the mood for an RMA (ill go under warranty when I have the time), but I'm wondering if this is normal for dv6/7 and how to reduce it if possible.

 

It is like 18v DC!! ... Do you want to explain exactly how you think you are being shocked ... are you using it in the bathtub? There is FAR more energy in a car battery (although less volts), and your skin resistance is way too high to feel anything if you grasp each terminal. Detecting anything should be impossible unless you are using your tongue (or thin skinned I guess) ... and to claim that you experienced the same thing on a different computer, makes me think you more likely need psychiatric attention.

When screens were backlit using florescent tubes, MAYBE [Quite a stretch] you could have a bad inverter ... these use LEDS ... no inverter.

 

Uh, if it's not grounded correctly you can definitely get little zaps. It happens.

 

then you have a defective power supply (or more likely static electricity) ... there is NO WAY a normal human is going to detect 18v under ordinary conditions... now if you are willing to use your tongue (or have open sores maybe) ... that could be a different story... and then getting shocked is NOT your worst problem.

(I sure hope all those electrical bioengineering classes weren't a complete waste)

Clearly not ordinary conditions. I did have an older Dell laptop that had a tendency to give out tingles.

OP, get the adapter replaced.

 

I'm using it on a desk plugged in. It's not all the time. Atm I can shove my finger against the ports and I feel just slight static, but yesterday my hand slipped to the side (desk + plugged in) and it felt like I was shocked and it HURT. (for a couple seconds lol)


Are adapters covered under warranty?

Side-note: what do you guys use to clean your screen/laptop for the dark umber color? it's getting kind of obvious now, though I don't really care.

 

I don't know about HP, but I never had an issue getting adapters replaced under warranty by Dell. If it's shocking you and causing pain, I would think they'd be willing to replace it.

 

weeeeeeeellll in MY electrical engineering classes we used to have this little thing called a nine volt battery.....and I could feel that...
seer

 

Yeah. Warranty covers adapter. I got mine replaced and it was shipped with 1 day delivery. However, make sure your outlet is actually grounded. GFCI may not have a ground. If you live in an old house, you may not have a ground. If the issue is your outlet, the new adapter will have the same issue.

 

yeah, on your TONGUE!
You could try the tongue thing on a car battery too! and burn part of it off.
Hook a 9vdc to an inverter (DC->AC) and jack the voltage way up you feel THAT too.
Insert the electrodes underneath the skin, and you are dead
A mere mortal would have a hard time detecting 24vdc or less, by normal contact
consider yourself special.

 

I did a search online to see if anyone else had the problem and when I read all of the replies I had to register and comment. I have a dv7 Core i5, ATI Mobility Radeon HD 5470. If I touch the side casing of the computer it shocks me. A little shock but trust me you can feel it and it stings. The first few times I thought it was just user error(like 90% of pc problems), like the casing had caught my forearm hair and pulled it, but now after at least twenty shocks I had to look online to find the solution so my laptop will stop shocking me. What surprises me is that all these people are so sure that it is impossible... Well believe it or not, it is possible. No real solution except sending it back on this forum.

 

My brothers macbook pro used to give me a HUGE shock when it was charging.
Im not talking about any ordinary shock which makes you feel uneasy, im talking about the kind of shock which may electrocute you.

Thats why, i never touched his or anyone elses MBP again.

 

I know this is a few months old but I had to add my 2 cents.

@Jerohm You have no idea what you are talking about or someone gave you wrong information. I guarantee I can build a circuit with a single 1.5v DC Double A battery that could kill you. Just cause it's low voltage does not mean you won't feel it. For example, have you ever heard of people making stun guns out of a disposable camera? Well those are usually powered by 2 double A batteries in series which would be about 3 volts. And if you've ever been bit by one, there's no way you would tell me that you can't feel it. Before telling this guy he's full of it, you should probably learn a bit about how electricity works. Now to go on topic, my DV7 shocks me as well but only when I'm barefoot or grounded good but that's because my apartment doesn't have any grounded outlets and it's not getting grounded. When I'm not being shocked though I can touch the brushed metal case anywhere and rub it a little and I can tell there's electricity running through it. I get a little statically charged. I unfortunately don't have a solution for you. All I can say is if you're plugged into a grounded outlet, take a multimeter to it and see if the outlet truly is properly grounded. If it is, like others said, it's probably a faulty adapter. If not, you found your problem.

 

yeah, maybe if you connect the electrodes under the skin(or tongue) and/or directly to the heart. Considering skin resistance, is an entirely different situation... and as far as PERCEPTION is concerned, voltage (or more importantly, amperge) DOES matter. Thresholds of PERCEPTION(not shock mind you) for AC and DC are VERY different; under 30vdc is highly unlikely, even by women. Most people have absolutely no threshold of PERCEPTION experiences with VDC whatsoever... unless they test 9v batteries with their tongue. Stay in school.

I had the same problem with my first zenbook, not only shocking but dragging the power cord across the lid would make sparks lol.

 

I had to register here and necro post just because this whole thread bothered me a little. My dv6 gives me a shock from time to time as well. It comes from the HDMI port usually when I am gaming. Just because the power supply only puts out 18.5 volts, doesn't mean that is the only voltage being used inside the computer. Consider this.
Power P(wattage) = I(current) * V(voltage)
My dv6 uses a 65W power supply so let us use that as an example.
And we will use your 30V in this example as well.
so,..

65W = X * 30V

X = 2.166

So as you can see a 65W power supply is capable of producing 30V with 2.166 amps of current if the conversion is being done somewhere inside the computer,, by some component.

Let's get a little more dramatic.

Let's use 1000V as our example here, I guarantee you 1000V at any amperage, you will feel the shock.

65W = X * 1000V

X = .065 amps

Once again A 65W power supply is capable of producing 1000V with .065 amps of current if the conversion is being done somewhere inside the computer, by some component.

This is called the Power Triangle, or Joules Law.

Just because you start with a certain voltage and amperage does not mean you are going to end up with that same voltage and amperage. The only thing that will remain constant is the amount of power (wattage) the power supply is capable of putting out.

So, maybe you need to go back to school instead of rolling your eyes and telling others to stay in school.

EDIT:
I just wanted to add, as a previous poster stated, the actual problem is probably due to a bad ground somewhere in your house wiring. Especially if you feel the electricity only while plugged in to a wall outlet. The whole purpose of a ground wire is to avoid having electricity running through the case of whatever device you are using. Immagine touching your washing machine and getting hit with 240v at say 7 to 10 amps. Ouch, or more likely RIP.
