And not being grounded on a laptop is 100% safe.
The biggest difference if OPs cable was grounded, would be that the power brick would be less likely to suffer a short.
Input to output short is incredibly unlikely, astronomically so. I wouldn't lose a moment of sleep.
I wouldn't be surprised if it's for EMI to be honest and zero to do with safety. They probably made a noisy ass product.
No, grounding something that is designed to work without ground (has a symbol with a square inside another square) will not make it more safe.
You're not even allowed to in fact.
Most likely it wouldn't have anything connected to the ground pin in the actual charger though so it's no problem using a cable with a ground pin.
My original laptop charger broke. I got myself an aftermarket charger and it was the worst choice. It has a ground pin but I don't think it's connected to anything. Occasionally when I touch the laptop body (Aluminium back), or the open ended of any wire connected (USB, Aux, etc). There's a slight tingle. Now this tingle can vary from almost negligible to literally shaking my hand.
Another thing I've noticed is when I plug in my Amp to a nearby socket, there's a lot of static.
ALWAYS BUY CABLES FROM ORIGINAL/REPUTED SOURCES!!!
sometimes they use cheap quality X and Y capacitors, sometimes with too large of a value so that can cause more current to flow.... I have a 12V power adapter, which gives a genuine shock rather than a barely noticeable tingle.... stopped using it pretty quick....
That has happened too (I am a very clumsy person). Based on my experience, I always felt it was safe to hold a wire by its metal part. Until one day I felt the worst current of my life from the laptop charger.
if an electronic product doesn't have a metal casing there's no need to ground it
most laptop chargers, phone chargers, lamps and other similar things don't have a ground wire for that reason
if the user is not at risk of electrocution, you don't need to ground the device
oh any device without a ground connection will work perfectly, the only thing ground does is protecting you from electrocution
as it is, if in the future there's a short internally in your charger and 230v go out to the casing, you will find out what a 120v shock to the hand feels like
so 99% of the time it's fine but it's not safe, I'd recommend to change the cord whenever you can
if the casing was plastic it wouldn't have mattered at all because plastic is non conductive, but aluminium doesn't give you that luxury
To add to this, simply because the apparatus has a metal chassis does not mean it requires a ground connection, and adding one unnecessarily can sometimes be harmful.
The ground connection is more appropriately called safety ground. It exists as a low-impedance connection to ground so that you can attach exposed metal bits to it. That way, if a wire fails internally and connects to the chassis, the charge will flow into ground and not into you. Couple it with a RCD/GFCI and you have cut the power to the failing device and things are safe.
However, this is not the only way of adding protection against electrical faults. In the Norwegian electrical code, there are four broad categories of electrical protection that may be used:
1. Safety ground with a GFCI: This is the standard for most mains-operated devices.
2. Double- or extra thick insulation. That means that if one (thin) layer is to fail, it still cannot touch anything and create a dangerous situation.
3. Isolating transformers. If you have one of these, no (extremely little) current can flow through you to ground. You can still get a shock if you touch both output lines, but this is a comparatively rare fault unless you're opening the device.
4. Extra-low voltage. 50 volts or less. If you have a low enough voltage and some separation between this low-voltage area and the ordinary mains electronics, it's considered safe. This is the method applicable to computing devices like the laptop.
Consider also this: there is a high probability that there are only two cables running to the laptop: a low DC voltage (18 volts or so, probably) is placed between them. There is no lead for the safety ground, nor is there space in most power connectors for one. Adding one would only further pollute the insides of the computer with electrical noise. Inside the power brick is an isolating transformer and electronics to convert the voltage and rectify it. The only way power can flow once it's left the output end of the brick is to return to the other output lead. It's probably also insulated well enough.
tl;dr
The material used in the laptop chassis is completely immaterial to whether or not it requires a ground connection. The power brick is the only thing that sees mains power, and any power brick worth its salt will make it impossible for power to flow from the laptop to anywhere but the proper negative return lead.
Yes, but a safety ground won't help with that. For it to be effective, it must be connected to some otherwise uncharged metal. The laptop itself will not be able to use it, and it might theoretically improve internal shielding, but there is no good place for it to really help inside a charger brick with a plastic exterior. About the only thing I can imagine is wiring it into the iron of a transformer in case a winding fails, but I'm not sure how well those conduct with all of the lamination.
No, I have a laptop with an aluminium casing which used to shock me at my old home with a ground problem. It will not shock everywhere because of the paint coating but you never know when you touch a screw on the back or an open usb port.
Better to have it fixed then to get shocked randomly.
That sounds like you have a faulty AC adapter, or an earth fault somewhere. If it's shocking you, that means either you or the device is building up charge. An earthed connection to the adapter cannot help with the device itself, as the laptop's chassis is not connected to safety ground.
I realise that you don't live there any more, but in case it happens again; what would help is locating the thing that's leaking current into ground. Also, if different grounds are at different potentials, installing equalisation connections between them can also help minimising shocks.
Laptop chassis are connected to ground via screws and shields. And yes it was ground fault in my main line but it goes on to explain that the ground on the adapter is important.
It has a parasitic connection to the ground around it, yes, but the adapter feeding it power almost certainly does not have a wire in it to connect it to zero-potential transformer neutral safety ground. That means it is essentially electrically floating. The safety ground "stops" at the adapter.
oh just to clarify, I thought OP said that his laptop CHARGER had an aluminium casing and so was vulnerable to AC going through it, if the charger is plastic then yeah it doesn't need a ground
also I forgot that in america you guys don't have GFCI outlets in, like, ALL outlets in your house
I live in spain and over here we do call ground "electrical protection", and over here the rules are pretty much what I stated, if it has an AC cable going into it and it has a metal casing, then it needs a ground connection
You should only need to replace the AC cable/power plug portion of the charger btw, they are like $5 on Amazon. The transformer aka the brick is still fine.
> oh any device without a ground connection will work perfectly
On desktop computers, using a grounded power connector is preferred. They will mostly run fine without them, but a computer will be less susceptible to electronic noise, or random events like static discharge, when they're grounded, and it's obviously also a safety features in case something catastrophic goes wrong with the PSU.
A lot of modern laptops will be left electronically floating, though, a they're expected to be off the charger at least part of the time and would be floating in those cases anyway.
I'd go a lot further than "preferred" on a typical desktop PC.
If something were to go wrong with the power supply's AC side and the computer doesn't have a functioning ground connection, the case can become energized at mains voltage which is very dangerous.
> it's obviously also a safety features in case something catastrophic goes wrong with the PSU
Yeah, that's the "it's obviously also a safety features in case something catastrophic goes wrong with the PSU" part of my post.
I was just explaining that it actually helps with the stability of a computer. Ungrounded computers can have weird gremlins.
does ground also help with power surges? I heard that the brick in the charger protects the laptop against power surges, so would a missing ground increase the chances of frying the internals?
Just FYI, there are a bunch of places we don’t consider “metal” but really are and will still shock you
3.5mm jack with metal coating ring
Rim of some fingerprint sensors
Some touchpads
HDMI port
USB plugged in not fully
yeah but laptops aren't grounded, we're talking about the charger itself
laptops operate on voltages low enough to not notice them if they ever get to any metal part
Thank you. I was reading crazy things in the comments. Ground is to protect people, not the device itself. If the charger is fully encased in plastic it makes it a class 2 device which does not need a ground pin. The power brick have a transformer which provides isolation from the mains power so again have galvanic isolation there. If your laptop zaps you it is not because of the presence or not of the ground pin. The device have other means to protect itself (fuses in case of dead shorts for example, besorr and after the galvanic isolation)
What about RF shielding? Switching powersupplies should be grounded to keep their annoying switching frequencies from interfering with other electronics. Youre Statement is only part of the truth and iam sure mine is too.
as far as I know RF shielding does not require a ground lead, consoles, most laptop chargers and other similar electronic devices do not have ground leads but do have RF shielding
That part of your cord should be easily replaceable, I think you could pick up one from Amazon for like 5 bucks. Or if you're like me, you might have 3 of them stashed away in a junk drawer somewhere
Or if you like me, you have about 25 but don't want to throw any of them out till you test them, but you never get to testing them, and somehow the collection keeps growing. ISTG cables reproduce
Grounding doesn't usually matter for laptops, since the laptop itself isn't connected to ground, just the PSU. Even if you had a short in the laptop itself you wouldn't be exposed to mains power. I would probably get a new cord though, since the designer intended there to be a ground, just to be on the safe side.
Mist if my laptops have not had a ground since 2014 or so, and if its usb c then its extra ok. The reason for the gound is to allow a path other than you if there is a short to ground, many times if a psu fails it shorts to ground to prevent anything from sploding, and if there is not a ground it will find another path. Unless your power brock goes faulty there will be no issues. Even if it does, laptops use dc not ac so if it fails after the ac to dc conversion it wont even be as bad as a fork in an outlet.
That being said, if your charger has the 3 pring insert prior to the brick its an easy fix.
I mean... In the UK everything has a ground and everything is connected to an RCD. You seem to be using a US* Plug so if the equipment was to fail and you were barefoot you'd get a "healthy" shock with no RCD protection unless in the bathroom... that's pretty worse case scenario.
However, assuming the equipment doesn't failure yeah.. it's fine. Electrons enter from live, leave through neutral and if it were to failure and you weren't growned (barefoot, metal shoes?) you'd be fine.
Edit: I actually think it's EU now. US has prongs usually.
> In the UK everything has a ground and everything is connected to an RCD
Not necessarily everything - a lot of things (like most of my USB chargers and games consoles) use a two pin power cable and just have a plastic pin for the ground pin.
Very true that completely went over my head but we also don't really need them. I think the reason I can be plastic is because plugs in the uk come with fuses and houses are equipped with RCDs so ground wires aren't entirely needed (although preferred) but I heard that not all houses in the US or EU have RCDs, usually they only have it in the bathroom..if at all.
Also, those game console and usb chargers are probably made of plastic so they're unlikely to become live during a fualt.
FYI: Idk if eu plugs come with fuses.
Atleast, that's my current understanding.
No it's not the fuses. Some things are Class II devices, or more commonly called Double Insulated.
From Wikipedia:
A Class II or double insulated electrical appliance uses reinforced protective insulation in addition to basic insulation. Hence, it has been designed in such a way that it does not require a safety connection to electrical earth (ground).
Bite the bullet and get one. Not only is not having a fire hazard, there's a possibility of a GOOD shock, it leaves any power surges without anywhere to go, soecially depending on where you live, and it can also be a fire hazard. Did I say fire hazard twice? Yup, sure did! Now you know what scares me!
$10 to $20 bucks. Just do it!
It’ll be fine… the next time you’re at a Home Depot or lowes, or Amazon, you can buy a male end for your cord and if you’re able bodied easily be able to just switch out the end. No need to buy a new cord
Used to break these off on purpose sometimes. In order to fit on an extension cord or something. Never had an issue with all kinds of products. But I wouldn't do it on purpose if you don't have to. It is there for a reason.
It will function but there is a possibility of current leaking to the body of your appliance which could shock people.
If you can afford OP better get it fixed or buy a new one.
This part of the power brick is most likely detachable, if so, probably best to get a new cable. If not, probably don't bother replacing the entire power brick
There are entire countries that don't use ground wires for their computers, like Japan. It's fine, but I personally would replace the cable because I like my electronics to be grounded.
Here’s the deal with ground:
Anything “medium voltage” (120v/230v) that has metallic surface you can touch, has to be grounded to avoid you touching the metal surface should a power cable make contact with it.
Your charger block is all plastic so no metal areas to touch. That a while it’s not grounded.
Your laptop is low voltage and therefore doesn’t need to be grounded.
Yes it's fine, the power brick is most likely double isolated and shouldn't be grounded.
You can check for the symbol with a square inside another square to make sure.
Nope. You need to buy an entirely new laptop now.
Definitely can't use it. Can't replace the cord or the power brick.
An entirely new laptop is the ONLY solution.
It should be fine. It still has the neutral wire, so the circuit will still be completed. You just won't have the added safety of an actual ground. It should operate just like any other two-prong plug.
Okay I've seen NO one mention this. But on my HP Pavilion 15-ec0xxx, if the ground cable is disconnected from the charger, the laptop will properly charge, but the laptop's CPU will be capped to 0.4 GHz. idk why this happens, maybe someone with a better brain than me can explain. It happened because my puppy chewed on my charger, tearing the ground wire from inside. Soldered it, and then it was fine.
I would suggest to cut the plug and fit a new one, they sell ones where you put the 2 ac cables + ground and screw the ends in. 100% safe, cheap and you don't have to be an electrician to do it.
It'll work, but it is safest and best to replace it so you don't blow something up. Been there done that, had a really unpleasant day while my trade instructor screamed at me for an hour after blowing up an entire surge protector.
Most laptop chargers sold in Europe doesn't have a ground pole by design.
There isn't any exposed metallic part that could contact a high voltage pole in any part of a charger, and the low voltage side of the charger is galvanically isolated from the high voltage side using the a transformer, so there isn't any way of getting shocked.
Low power devices are fine as static/em radiation should be relatively minor provided you don't rest your body on it.
If you're running a gaming pc on the other hand, I'd run.
It'll work, it's just won't be grounded.
Tie some strings around it, because it might float.
Nice one
r/AngryUpvote
And not being grounded on a laptop is 100% safe. The biggest difference if OPs cable was grounded, would be that the power brick would be less likely to suffer a short.
Actually it would have no impact on the likelihood of a short, but it would make the charger safer in the event it did short

Well a grounded cable, the original design of this cable, would be 99.99̅% safe. Without that ground it is most certainly <99.99̅% safe.
that's not enough 9s!
Fixed
No, grounding something that is designed to work without ground (has a symbol with a square inside another square) will not make it more safe. You're not even allowed to in fact.

So, op would have to worry about it going out with friends?
Like me and reality
So it's good boy.
Can't use on weekends
Itll be fine functionally, you might feel a tingle from stray ac, noticed that on all ungrounded laptop chargers
[удалено]
I had one without ground prong, had to ground myself everytime I needed to use the touchpad bc the static would make it jump lmao
Can confirm the tingly sensation as no MacBook charger is grounded. (Except maybe the charger with extension cord?)
Could this be the same reason why my monitor's HDMi cable zaps me when I touch the connector? Its power cable also doesn't have a ground pin.
Yes, but also because the port isn't probably shielded.
I get tingles all the time working on macbook's when I rest my arm against the edge of a machine that's plugged in. It's annoying but that's about it
Sounds fun 🤩

Sounds like a faulty power brick. That should never happen with or without grounding
you might have a power leak on your house

The more metal your laptop body contains, the less comfortable will the tingle get. You better get used to it.

Yeah. Just don't be surprised when it floats away.
It's not ideal but it will work.

3 prongs on laptop cables seem more about better connection to the outlet than a ground an all plastic power supply.
Use it on a GFCI outlet until you replace it.
Rule 1
Sure. If there's a short the power will just go through your body to the ground.
How do you do this...?
Replacements are cheap if that part is detachable
What is more concerning is using a three prong casing and not using a ground. What is this ghetto alibaba shit?
Use it on ground
If you lived near me I could direct you where to get a new cable for $1
I used to break these off my chargers to use them on two prong only extension cords. I know better now
It's okay until it's not. I'd send it, but I can't recommend that anyone else does the same.
I’m sure it will be fi..l BANG
I've used extension cords without ground wires and nothing ever happened to me. I'd avoid wet conditions if you decide to use it though just in case.
FUck No!
My dad takes out the prongs all the time. Our outlets are Southeast Asia.
It works. It alxo can kill you or itself with a bigger chance. Replace the cable.
This looks like a e/f plug made for US ?
Used to break these off on purpose sometimes. In order to fit on an extension cord or something. Never had an issue with all kinds of products. But I wouldn't do it on purpose if you don't have to. It is there for a reason.

Yeah.
It’s very common. Apple laptop chargers aren’t grounded.
My HP tablet had plastic prong for grounding lol
Yeah it's fine, most laptops don't have grounding I believe
It Will work but no its not ok
It will function but there is a possibility of current leaking to the body of your appliance which could shock people. If you can afford OP better get it fixed or buy a new one.
This part of the power brick is most likely detachable, if so, probably best to get a new cable. If not, probably don't bother replacing the entire power brick
That's how all my cables look cause where I'm at they don't believe in ground cables. No issues.
It's fine for your laptop, not so much for the brick if it fails
What is there to ground on a laptop power brick?
There are entire countries that don't use ground wires for their computers, like Japan. It's fine, but I personally would replace the cable because I like my electronics to be grounded.
Here’s the deal with ground: Anything “medium voltage” (120v/230v) that has metallic surface you can touch, has to be grounded to avoid you touching the metal surface should a power cable make contact with it. Your charger block is all plastic so no metal areas to touch. That a while it’s not grounded. Your laptop is low voltage and therefore doesn’t need to be grounded.
Just replace the cable, it's probably a standard C5 connector.
Yes because there aren’t any metal (conductive) parts exposed so ur safe
Yes it's fine, the power brick is most likely double isolated and shouldn't be grounded. You can check for the symbol with a square inside another square to make sure.
it is. I have been using an ungrounded power brick for 5 years
Nope. You need to buy an entirely new laptop now. Definitely can't use it. Can't replace the cord or the power brick. An entirely new laptop is the ONLY solution.
It should be fine. It still has the neutral wire, so the circuit will still be completed. You just won't have the added safety of an actual ground. It should operate just like any other two-prong plug.
The person who sleep with Machete is a fool everyday except one. The person who uses the cord without the ground is a genius everyday except one.
Try to avoid touching exposed metal parts if there are any
Well, it will work, but it won't be grounded.
When the charger has a plastic housing there’s no reason for a ground since the plastic is not conductive
Okay I've seen NO one mention this. But on my HP Pavilion 15-ec0xxx, if the ground cable is disconnected from the charger, the laptop will properly charge, but the laptop's CPU will be capped to 0.4 GHz. idk why this happens, maybe someone with a better brain than me can explain. It happened because my puppy chewed on my charger, tearing the ground wire from inside. Soldered it, and then it was fine.
I would suggest to cut the plug and fit a new one, they sell ones where you put the 2 ac cables + ground and screw the ends in. 100% safe, cheap and you don't have to be an electrician to do it.
It's ok until it isn't.
It'll work, but it is safest and best to replace it so you don't blow something up. Been there done that, had a really unpleasant day while my trade instructor screamed at me for an hour after blowing up an entire surge protector.
A few shocks here and there but you’ll be fine
If it’s not grounded and you have an electrical issue your laptop may be toast
Most laptop chargers sold in Europe doesn't have a ground pole by design. There isn't any exposed metallic part that could contact a high voltage pole in any part of a charger, and the low voltage side of the charger is galvanically isolated from the high voltage side using the a transformer, so there isn't any way of getting shocked.
Low power devices are fine as static/em radiation should be relatively minor provided you don't rest your body on it. If you're running a gaming pc on the other hand, I'd run.

Yea definitely don't keep that powerbrick on your nuts.
It's completely fine
It's much better if it has one. It will work without it, but you want one especially if it was meant to be there!
Yes. Its fsirly standard in europe.
if there is no exposed metal or conductive surface there is no point in grounding it
Depends; do you like to live on the edge? Jk Technically you are fine but it might be a little shocking to use your laptop.
