Why is the laptop energized when not connected to the wall?

Umm. So I needed a larger screen for my laptop, so I plugged it into the desktop’s monitor, you see, so I would get a better view. This was when the laptop was running on a battery. But then the laptop became externally energized.

So I plugged it into the wall and it stopped being energized. The laptop is a Dell, so it should be of the utmost quality, and yet this happens. Is it supposed to do that? The laptop is not plastic or wood but metal, but I would have thought they would make thinking in their heads into the design, but maybe not?

Or is this completely normal and not supposed to happen at all? I mean surely that would be some sort of hazed?

Are you saying that you feel electric current from the laptop’s metal surfaces when you plug it into the wall (or, as it sounds, you unplug it)? If not, I’m not sure what you mean by “energized.”

I’ve read this a couple times and it sounds like, “If I connect an external monitor, I get a shock when I touch the laptop. When I plug the laptop into an outlet, the shock stops.”

Given the broken English in this post, coupled with the weird system-building ideas in the “how much is 35 kg thread” (which lacked the broken English, and had a lack of understanding of the metric system, which is used by almost everyone who isn’t American) I’m really beginning to wonder if the OP’s questions are sincere.

Yes, that is about it, really. I never noticed it before, because I’ve never needed to use the external monitor before. I mean I use the word “energize” because it sounds good and I’ve seen it used in similar places.

Umm, it is a genuine question. But the reason I asked how much 35 kg was is because I know the desktop I have right now that is a med tower but proper ATX is about 13 or 15 kg (just a guess) and it is relatively easy to pick up and walk around with, so I wondered if 35 kg would be the same.

I mean how would these scenarios come about if they were just made up? They are very specific, there is no way I could come up with them without them actually happening in real life.

It sounds like your monitor may have an electrical fault - possibly the grounding pins (and/or the metal shroud around them) is referenced to Live.

Or is it a CRT monitor and you’re putting the metal case of the laptop close enough to the glass for it to charge up with static electricity? (which might normally sink to ground when the laptop is connected to mains power)

Are you getting a ‘click’ or ‘buzz’ when you touch it?

You know it but it’s just a guess? Even when many people have already told you that your guess is wrong to the point of absurdity?

Are you using a grounded outlet for the monitor?

No, it is not a CRT monitor…

Hold on. I am am using BOTH the external monitor and the laptop monitor for productivity, so in what circumstances would I block the external monitor’s view with the laptop monitor? :confused:

The laptop is a fair distance away from the monitor. I could put up a photo to be really specific, though.

Well, the case is 8 kg, and it has a water cooling radiator and a heavy fan cooled video card, plus the other stuff, so it is probably about 14 kg at least.

I don’t know. I can’t see your desk from here, so I had to ask.

I’ve seen setups before where a CRT monitor was on a stand and the laptop was in front, so the top corner of the laptop screen was close enough to the bottom of the CRT screen to pick up a static charge.

The important part of my post was: Are you feeling a ‘click’ type electric shock, or a ‘buzz’?

The former is probably static. The latter is probably mains supply or similar.

Yes, but the screen’s plug has only 2 pins.

Well, it’s a constant stream of energy, not a short burst, so I would assume it’s a ‘buzzy’ effect. It kind of reminds me of a vibrating machine or a cat that purrs or buzzes when you rub it’s hair long enough.

your computer is shocking you, you know the reason, and you’re still doing this?

What do you mean? I am just asking what the cause is…? I am using it within specifications, so i shouldn’t have any energy penetrating to the exterior at all, none.

Stop feeding the troll…

If you are getting a continuous & repeated electrical shock from a computer when it’s connected to a monitor, and not just a static discharge - throw out the monitor and get a new one. Its chassis is probably shorted to a live wire inside.

No, a 35kg object is not as easy to pick up as a 13 or 15kg object. I hope that answers the question.

Your monitor is faulty in a way that is delivering current on a connector that should be at ground potential - and this ground is probably internally bonded to other metal parts of the device such as the casing.

So when you have your laptop plugged in to its own power supply, it’s got its own ground and this is protecting you from the current coming across from the monitor. When you have the laptop connected to the monitor on battery power, YOU are providing the path to ground.

Try a different monitor and see if the problem follows the laptop - I’m fairly sure it won’t - in which case, you should ditch the monitor (or return it if it is still in warranty)

Also, if it is indeed a faulty monitor, you’d probably get a shock from just touching the cable connected to the monitor (i.e. the end of the video cable that plugs into the laptop).

That’s the problem.

Needs to be grounded, or the common-mode EMI suppression capacitors float the chassis at 1/2 line voltage.

At least.throw the 2 pin monitor power cord in the trash and try a three pin cord into a three pin socket. You know the power cord on your monitor can be swapped, righr?

Well, it’s tied to a groundless adapter with a permanent output cord, so changing the cord would mean needing to change the cord and the adapter…

The plug that goes into the monitor is just a circular plug that goes right in.

Well, it was bought in the store like that, so I doubt the warranty would magically change the design of the original product.
