Just Brought a new Aspire 5. When its plugged in for charging it gives a tingling sensation on the metal parts surrounding its keyboard. It isn't easily noticible, but when you move your fingers over the metal body, you feel a small current sensation. Should I call the service centre? will this Damage my Motherboard or other laptop circuits... plz help

    No, it shouldn't damage the mainboard. But does the tingling seem to disappear if you can invert the charger's wall plug? Jack E/NJ

    How do i invert a 3 pin charging plug? I've tried all accessible ports in my vicinity... it's the same problem in all. When I rest my finger/hand on any metal part of the keyboard area, the tingling sensation stops from all areas when i check with my other hand. As soon as i remove the finger/hand touching the metal part, the tingling sensation starts again.

    Does the tingling feel stronger or weaker when you place a finger on a KB metal part and then glide a finger on the other hand over a grounded metal part on the mains receptacle? If stronger, immediately notify the service center that the charger's output plug is not properly isolated from the mains. Jack E/NJ

    you want me to touch the KB metal part and the ground line of the socket simultaneously to notice any change?

    Even on 220V mains, any leakage should be less than about 50v but feel noticeably different than what you tried so far. You're also not trying to grasp the metal part but lightly glide a finger over its surface. You could also substitute gliding a finger over a large metal object such as a metal table or chair to act as a capacitive ground. If you're doubtful, you could use a multimeter with AC mV or V range first. Jack E/NJ

    It's most likely that the earthing (ground) of your wall outlet is either not installed or came disconnected.

    You can purchase a GFCI tester (couple dollars) and check the code readout.

    Thanks @Red-Sand . Other wall outlets apparently also gave tingling (@DJSocra >>>I've tried all accessible ports in my vicinity>>>). Poor grounds can affect the charger's external metal parts but shouldn't affect its isolated DC output unless the isolation failed. Jack E/NJ

    Thanks @Red-Sand , yes that's what came to my mind initially too, that's why i tried using multiple sockets. It happens on all of them. I also have a lot of other metal bodied electrical appliances which work on the same set of sockets without any leakage current. So that's why I'd this intense conundrum.

    OK. Are your mains receptacles 220V or 110V? Jack E/NJ

    My apologizes you're right @JackE

    JackE is most likely correct in that the charger is leaking AC in which case the current has found a low resistance path through your body.

    I second using a multimeter and check if there is any AC current. If there is any then contact Acer for replacement options.

    @JackE, Voltage 230V, Frequency 50 Hz

    @DJSocra >>> Voltage 230V, Frequency 50 Hz>>>

    Do you have access to a multimeter? If not, return the system or the charger to the vendor as defective for a replacement or refund ASAP. Warranty service will take longer. Jack E/N

    @Fahimalwyz4u18 No, it shouldn't affect the laptop. The issue is if the charger's output plug to the laptop is not well isolated from its 110 or 220 VAC wall outlet, then a significant AC voltage might build up on laptop's exterior metal parts giving a tingling feeling. Jack E/NJ

    To take back some negative comments about Acer that I posted yesterday. I checked my three pin plug adapter which enables my Acer laptop charger - US type plug - to be connected to the power (mains) outlet - British type. The adapter was the problem - very poorly constructed with some flimsy loose components - and very likely the cause of the leakage and tingling sensation. I have now connected the charger to the mains via an extension cable configured for both US and British type plugs. Now there is no tingling sensation. Apologies for the Boeing Super Max comparison and remarks which were uncalled for.
