Lenovo Charger Electric Shock - Lenovo P2 Guides, News, & Discussion

While charging the phone, I feel mild electric shock upon touching the back panel (metal part) of the phone. Using original Lenovo charger that came in the box. I tried different usb cables but same result

I think this is normal behaviour. My P2 does that aswell

[Q] Plug Adapter For Charger

First things first just got my transformer and it is awesome! However the little charger thing is rubbish the plug that connects to it didn't seem to want to connect so after applying more force I managed to sort of wedge it on. However it is quite loose and any movement stops it charging! Are you supposed to push some sort of tab to attach the plug or does everybody else have this problem? Its a UK plug BTW
I'd guess youre not pushing hard enough!
If you fingers arent going white and they dont hurt afterwards, you need to push harder.
When fully connected the flat bottom of the UK plug overlaps the bottom of the adapter by less than the thickness of a fingernail.
Apparently it's very difficult to connect the two pieces. Many people have said that they thought their charger would break with the amount of force needed. Maybe try pushing harder? I can't help you any more than that I'm afraid as I don't have my TF yet.

Once they are connected - Try taking them apart again, Impossible!
Gave it a good shove and broke that little plastic thing that sticks out off :-S nothing abit of duck tape didn't fix though. Still seems a shame the build quality of the tablet and especially the keyboard is very high then they give us a crap charger and tiny wire. Also one charger for both the tablet and keyboard!
I had this issue and it ended up bending the little plastic bit which I used a knife to push it back to shape and then managed to clip it in. This makes me think it wasn't perfectly lined up in the first place so guess you have to have it perfect otherwise you will end up breaking that little plastic bit off.

whoa you're right D: I just tried.
My charger was already connected to the plug. It almost seems like one piece. Do the US unit have one piece charger?

US chargers do not come in one piece...i know, cause i lost mine...:-T...waiting for asus or a 3rd party to start selling some adapters to charge...borrowing a friends charger in the meantime since he got a transformer too...

following a tip from another user i went to best buy and purchased a dynex dx-ua which comes with many different tips one being a usb tip. It works perfect for the transformer and the cord is really long. I finally have my new transformer charging since the plug that came with it did not work at all. the dynex dx-ua is 29.99 at bestbuy try it out if you need a charger.

Does this unit have a 15 volt setting to match the original charger?
The easiest and safest way is probably alligning it and oush it in on a flat surface. That's what I did and it went in without a sweat. These kind of chargers are quiet common now so manufactures only have one charger for the whole-world making it easier to produce and all they have to do is give you different sockets for different regions.

it has switches that go from 3.3 to 11 volts but its charging my transformer fine.
the dynex charges at 11 volts / 1.5 amps. its a much better idea then using the crap charger that is supplied. here is a pic of my melted charger.

'Shocking Sensation" Low current running through backcover while charging

My sensation has a low voltage current running through the cover while charging. When holding the device while plugged in you get "shocked" (its better described as a tingly feeling). I did not have this problem before but i first noticed it after i got my sensation fixed by Vodafone. I send it in for repair and i don't know wat the exact problem was but they replaced the whole motherboard.
Does anyone have or had the same problem or have any ideas what i could do about it because i don't really want to sent it in again after last time when i had to go without my phone for 3 weeks.
Charger is probably defective. AC current should never get to the phone, but is coming in thru the ground in the charge cable.

or as the antennas are in the back cover this could be another issue?
I have the same issue when I charge the phone with a 3rd party dock. I can't remember having the issue with the AC charger. I'm going to test this tomorrow. However, I don't see this as a problem.
I dont think it is the charger because it also accurs when charging via my usb port on my laptop with a different cable. Its just so weird lol.
Maybe it is indeed the antennas. I will try with a backcover of the sensation of a friend of mine, when i have the chance, to see what happens. It is not really a big problem but i'm worried this will lead to other problems.
I also facing the same problem since beginning of buying this sensation. I'm using the stock charger that come with the phone. I think this is normal. Its happen to all my phone before (HD2, Desire, DHD and now sensation).
No others side effect happen from this tingly feeling to the phone.
Stock psu provides 5V DC.
One suggested solution is carefully bend up the silver contact on the back of the phone.

yes bending the contacts works, and you're good with soldering iron try putting some solder on the housing itself to give full contact to the back housing. works for me and there's a thread on this (with pictures too) try a search for that thread

This issue may be due to it being repaired, I mean everyone has an off day and makes a mistake. But also you are not the first person that has posted noticing the tingling sensation you get when you are charging your Sensation either. So who knows this could be yet another small problem us users are finding with the device, I have not passed judgment yet.

This is highly unlikely, most standard USB wall chargers do not have a ground prong to connect to insert into the ground terminal of a wall receptical. Also a USB cable only has two wires for power transfer. Meaning one is for the positive and one for the negative to complete the circuit. Not to mention if this was the cause the OP would not be complaining about getting a tingle, but of constantly having to re trip a breacker or replace a blown fuzz.
I don't get shocked if I touch the phone while it's charging but if I touch it with the dorsal side of my finger/hand there is a slight buzzing feeling, like a high frequency, low amplitude vibration. This only happens if I touch it with only one hand/finger. If there are more contact points, the buzzing feeling disappears. So when I pick up the phone the buzzing disappears.

In car wireless charging

i just put in the wireless charging mat in my car and its great. very useful. the way im using it is perfect for me in case any of you want to do the same.
what i bought was the LG charging mat (the cheap one) and killed the speaker in it so it doesnt beep constantly. i always drop my phone on top of the center console when i drive and (i know i shouldnt but) use it constantly to switch through songs while its connected to my car with bluetooth. and do other phone stuff like text once in a while (may i burn in hell, i know i know). the qi charging mat fit perfectly on the center console.
unfortunately, that charging mat came with a wall charger and not a usb charger. so i bought a power converter that went from a car charging port to a wall outlet.
it all fit perfectly and seeminglessly. i guess it depends on the car because not all cars have their cigarette lighters arranged the way i do.
here are some pictures of the outcome.
That looks great haha, does the charging mat "grip" the phone with a rubberized surface (or something of that sort) or do you have to worry about it sliding around?
Sent from my Nexus 4 using xda app-developers app
That looks really good. I wish my car had its cigarette lighter in the center console instead of on the dash, if I do the same thing I will have wires running all over the place.
I would add one of those sticky pads on top of the charging pad to prevent the phone from flying off the charger in a short stop or sharp turn at 50 mph lol.
I have seen a few pick up trucks that have center consoles with a recessed cavity in it's armrest (late mode Chevys) that have potential for pad installs like yours.
Actually I have the ringke slim case on my phone so it doesn't slide around as much. But if the phone was naked, yeah it would fly off. The pad surface is pretty grippy though. Works perfect. It's even better because I put an NFC tag on it so every time I drop my phone on it, Bluetooth turns on, WiFi turns off. Lol
I can't see the images?

Does the N4 continually read the NFC tag when its placed onto it, draining the battery? or does the NFC only read once and shut off?

Mentioned it in the op. I bought a converter/amp to convert the power from the car charger to a wall charger equivalent. The plug of the charging mat goes into that converter, then the converter goes into the car.
And the NFC just reads once every time you put it there. So no I don't think it's continuous. But yeah it works great Lol.

It wasn't quite clear to me as you are actually using an inverter with the stock wall wart, and right?
I have to think that using a cheap inverter (square wave) to power an ac-dc power supply is extremely inefficient. You may not want to keep this plugged in 24/7 as inverters can draw a fair amount of current just idling.
I sourced one of these - http://www.bixnet.com/12vdcto19vdc.html - that would be far more efficient, and and draw virtually nothing at idle. Seems 19vdc is more common than I thought as it is a common input for laptops.

Idk much about electrical engineering. I just went to Fry's and asked which one would do what I'm trying to achieve. When the car is not running, the cigarette lighters don't get any power. If that's what you meant by leaving it plugged in. Yeah I agree though, you can't really get efficient wall socket quality power. But the thing I bought gives just enough to power the lg charger which is all I need. I'm leaving it plugged in cuz it's practically turned off when the car is not running. But thanks for the heads up. I was more concerned about it overheating but my car is smart lol. Inside the center compartment there is an ac vent lmao. So while driving, air will just flow there.
And that link you gave. That thing looks like it would be perfect for me Lol. I might buy that one if the one I got gives me problems

Battery suddenly dead on both dock and tablet

Until yesterday, my TF700 was working perfectly fine, but now I'm concerned as the battery in both the dock and the tablet have stopped working.
The AC adaptor's connected to the dock and I always charged both the tablet and the dock together for the most part.
I went to check the device this morning and suddenly found that they're not working at all.
Yesterday evening, I tried switching on the tablet and it would switch on and reach the ASUS screen, but not fully boot up.
I bought it from Amazon's Amazon Warehouse division and I have until the 31st to return this, but in the meantime, I'd like to know why the batteries have died on me suddenly and is there anything I can do about it.

If it's a genuine hardware failure, you'd have to return -- unless you're very proficient at handling and replacing sensitive electronics yourself (microwelding, for example).
It has been reported before, and could be fixe din almost every case by letting the 700 be dead for at least an hour, and then let it fully charge while off (!) -- just let it sit hoked up to the wall charger for at least 8 hours. Then try to turn it on again.
Good luck.

It never hurts trying -- you aren't exactly the first to describe this, but luckily, pretty much all of the others were saved.
I finally managed to get the problem sorted out as it seems that the connection to the port on the keyboard had somehow come a bit loose without me noticing it.
Unfortunately, I have a new problem in that the cable itself seems to have died in that it won't work any more with the adapter as it started crackling a bit when I knocked the connector attached to the AC adaptor itself gently by accident. :crying:

Well, I hope I am right in assuming this is not your luckiest week, huh? Is the cable damaged near the wall charging part? (That's what I understand.) The replacement cables probably are not that expensive, so I'd plonk down on a new one instead of initiating "daredevil repair mode".
Saying that gives me that MacGyver feeling. Duct tape and a pair of scissors would be all that he needs to fix this.
Oh, and maybe a pair of toothpicks and an old sock, just for looks.

The cable itself is fine (it's not worn down to the wire literally like a lot of cables and AC adapters you get for devices like iPods and Galaxy S II's), it's just that it has this weird burnt-like smell at the end connector that plus into the USB socket on the AC adaptor.
As for replacement cables, I'm surprised that they're not that easy to buy offline.

Agreed -- buying them offline is a definite hassle. I have seen them online, though, and you can even hunt down the charger parts or the TF101 and TF201 Prime. They will work flawlessly.
BTW and FWIW (gotta love acronyms), my charging cable smells a bit funny at the end too. This specific one has to put through a lot of power, so I'm not even that surprised.

Just giving you guys a update concerning my device: It seems now that both batteries don't want to work any more for some reason or other as of yesterday. I've checked both the official USB cable and a third-party cable plugged into the official USB plug and they're not charging up the device at all.
The tablet can connect to my laptop as a media device without any problems, but I'm confused as to why it's not working at all when plugged into a USB adapter.
In any case, I'm going to order a AC adapter from eBay later today and see if that works or not.

Slight wiggle with cable and charger port ?

Hey guys. I've searched but couldn't find a solution.
I've got a very slight wiggle between my cable and charger socket on my honor 8.
Now I don't know of this is normal or not ? I can very slightly wiggle the cable from right to left, and up to down.
Is this normal ? Do other people get this as well ? When I say wiggle I mean literally a mil or two up and down, left and right.
Edit. Literally just tried wiggling the power connector inside the phone with a pair of tweezers. And it literally doesn't move. So I'm thinking it's the cable that is giving the couple of mil wiggle room??
Cheers !
Why are you even fidgeting with your device like that? Is it charging when plugged in? You're going to cause more damage.

Eh?? All I did was plug my cable in to my phone and it felt a little loose/wiggly. So I'm just asking a legit question ?? I'm not going out my way to cause damage.
I've jumped from an iPhone 7 to android. (which to be honest is a good thing right ?) I'm just asking is all?!
And yes it is charging. But when you plug a cable in like that, is it supposed to wiggle as much as it does ?
There is room for movement left to right this is normal. What is not normal is placing foreign objects inside of one's connect and trying to pull it.. Like the other member said if it's working as it should charging sync etc leave it well alone..

Okay. Thank you. As I said. I'm used to an iPhone 7. Where the charger cable fits like a glove.
If this is normal to have a bit of wiggle room then I'm okay with that.
There shouldn't be allot of movement when you have your device plugged into the charger. If you can get allot of movement when wiggling the cable then I suggest you send it back to Honor for inspection. As the USB port maybe loosely connected.
it shouldnt wiggle, get it fixed on the warranty
It isn't normal, when I charge my phone, the cable is fixed like a rock
Ok. Thank you for the swift replies guys.

Take it to a repair center ASAP
I have a bit of wiggle too. The port is solid and does not move, so it must be between the port and cable connector. I would not worry about it. There is a lot of different connection types that has a bit of wiggle sometimes. You will notice if it becomes a problem.
Type C Port Wiggle
I just bought a new factory sealed Galaxy Tab S3 from B&H Photo and the charging plug when plugged into the tablet does have about a millimeter of wiggle room in all directions, left, right, up, and down. The charge never drops. The slightest touch doesn't cause the plug to wiggle, I'm talking about actually using a little bit of force, not much...just a little.
My other devices use micro B and the charging ports in those devices fit tight so I had the same concern too but it turns out that the Type C charging port is designed with that slight wiggle room for some reason.
Just wanted to add my 2 cents to this concern on hopes that this information serves useful to someone.
