Vibration of laptop case during charging

Good evening

Is the charger resting on the table near the PC? It might be the one vibrating and transmitting to the PC? (poor quality transformer/rectifier?).
Or maybe the rectified current is not "clean" and contains harmonics...

Otherwise, the best option is to return it to customer service, as this is not normal; you risk having problems with the hard drive in the long run, and possibly other issues...
If you've had it for 2 weeks, it's still under warranty...

If customer service doesn't want to help, make reservations by registered letter...

See you soon

Hello,

I have the same problem, but exactly in the opposite situation: the phenomenon only occurs if the power outlet is unplugged.
I feel the vibrations when I gently run my hand over the casing. At first, I thought it was the brushed effect of the aluminum against the fingerprints, but when I plug the computer back in, the vibrations disappear...
I've had it since yesterday, and I'm hesitant to return it (I went through a lot of trouble to set everything up on it!...)

Hello everyone,

Ah "delighted" to read that some of you are experiencing the same problem as me!

I would be interested to read your feedback on your experiences, what your customer services have diagnosed, the solutions found, etc.

I feel the same, the aluminum case vibrates very slightly everywhere. I can feel it and it's really very unpleasant. My boyfriend (with heavier hands, thicker skin) hardly feels anything...
It feels like we're in a Science Fiction series!!

I had the same issue with a friend's PC. No sensation on the plastic wrist rests of the MACs.

Asus X53SV 15 inch laptop bought brand new yesterday.
Following a call to FNAC customer service, I’m going to see a repairman in the store right away but I'm afraid he won't feel anything with his (big?) fingers!

Hoping to hear from you
Thank you.

Problem the same when brushing against the casing of a HP Pavilion dm4 and quite annoying in the long run (tension in the hands and wrists during prolonged typing). Probably related to the metallic nature of the casing as also noticed with a Dell Inspiron v13 in 2010 (titanium casing) and two ThinkPads (T in 2004 and X in 2009, magnesium alloy casing), but less pronounced than with the HP.

The phenomenon is diminished when the battery is disconnected although it doesn't disappear completely. It is amplified when connecting a monitor. It is also heightened when the power supply or the cable is tangled in a mess of wires...

At first, I assumed it was a vibration, but I think it's a bad ground (isolation) because with one hand on the PC and the other hand brushing against someone's skin the sensation of vibration is transferred to the touched skin... and I have the same issue with a metallic halogen light I've been moving from place to place... like the Dell and ThinkPads I've tried in various locations without noticing improvement. However, I have never found a solution...

EDIT: A lot of information here http://forum.macbidouille.com/lofiversion/index.php/t227461.html

I have the same issue with my PC and I think I've found the cause.

At work, I plug it into an outlet with a ground connection, and I don't feel any vibration.

However, at home, living in an old building, not all my outlets have a ground connection, and as a result, I feel the vibration.

Noticing the same phenomenon (I even transmit vibrations to people who touch me), I went to customer service. I was told that it was common with silver speakers (I don’t know what the material is). They all seemed to agree and be convinced by the explanation. And there you go.

Hello,

Having had this problem about 6 months to a year ago, I haven't taken the time to change my computer.

As a result, today the hard drive is in critical condition and may fail at any moment...

The power has also increased recently, don't let this problem linger. It's a loss in the making.

Best regards,

Hello Robisme

It is indeed very strange, especially when comparing the two cases...
There isn't much running in the PC, aside from the hard drive and fans, that could produce vibrations other than those possibly caused by the charger.

And we don't see why their speeds would vary depending on whether the PC is powered by the mains or not... But the fan speeds should adjust based on the internal temperature: do you notice any differences depending on the duration of use?
Because it does seem to be a phenomenon of resonance (amplification of vibrations at a specific frequency of excitation).

I think you should definitely send it back to the service center, because over time you risk damage. It would be a shame not to make use of the warranty...
And they should be aware of the problem...

In principle, they shouldn't touch the hard drive, unless they need to replace it if it has a defect (very unlikely, given the quality control of the drives). In that case, ask them to make a complete backup of the drive, and make a backup of your personal files yourself (you shouldn't have many).

Good luck...

See you soon

Hello,

I have the same issue with my HP Pavilion dv6, namely vibration of the casing when the laptop is plugged into the mains. How did you solve the problem? Did customer service respond to your issue?

Thank you in advance.

Hello,

The post is a bit dated, but for your info, I solved the same issue on a laptop with a brushed aluminum case by going to expose my problem at the retailer. I explained to him that a universal charger with a grounding plug would likely resolve my problem. He thought it was a good idea and offered me one as a goodwill gesture. And my problem is indeed perfectly resolved.
