Minor shock, static electricity on iPad 4

When I am using my iPad and touch the screen there is a minor shock sound, it sounds like a zip (static electricity). Could this be related to what is happening in China? Please help quickly.

this is normal behaivor and is usually just static build up. Recent reports on the unfortunate Chinese girl suggest she may have been using a counterfeit charger for her iPhone when the incident occurred.

Overheating and slight static electric shocks

Hi
I first want to say that I am in no way technical!!
I bought a Macbook Pro 15" late last year, so it is about 6 months old at this stage. I am concerned with 2 things. Firstly the heat that the machine is generating - I am not a gamer nor do I use many applications at the same time - usually all I have open are Finder, Firefox (maybe 3 tabs) and Skype. I did the iStat Nano app and the CPU is running at between 58 and 62 C. The heat is located on the top right side of the macbook (say from the bottom of the keyboard say the letter 'V' up and to the left edge of the machine). The rest of the device is about 10C cooler.
Is this normal? Can it be reduced? I can't even hear the fans but the iStat says that they are going at just under 2000 rpm.
The second issue is that on the edges of the computer I am getting mild (static) electric shocks. Is this normal(??)? I am not really generating much static myself so I assume it is coming from the device.
I would appreciate your views.
Regards
Adam

Hi adam, and a warm welcome to the forums.
A temperature of 58 to 62º for the CPU is really not all that high for an MBP (or any notebook running on a Core2Duo chip. It is the sort of temperature that usually occurs with moderate CPU use.The maximum operating temperature for these processors is around 100ºC. The fans usually start to kick up a little in speed when the temps reach around 70ºC, but won't reach full speed until it is significantly hotter than this.
Many people think that web browsers like Firefox or Safari are "low CPU" usage applications, but , depending on what sort of sites you are visiting, they can actually impose a substantial load. If you visit any sites that use Flash, for example, you will find that CPU usage by Firefox or Safari skyrocket.
Open up "Activity Monitor" (in your utilities folder) and keep an eye on Firefox's CPU usage while you visit various websites.
Head to http://www.cnn.com/video/ in Firefox and play the "lead" video , for example, and you will usually see CPU usage in Firefox increase to somewhere in the 60 to 80% range. Many, many sites use Flash for one purpose or another these days.
(Skype usually doesn't use much CPU, unless you fire up its video mode, in which case it too can become a heavy load)
So I wouldn't be worried about the temperatures you mention.
The "mild shock" matter that you mention is a longstanding issue with notebook computers of many brands. I first experienced it myself when using a PB12 in a remote part of Queensland a few years ago. The power supply of the unit that I was staying in was not properly earthed (and may have even had the "neutral" and "active" wiring reversed). I received noticeable shocks from the body of the computer.
Many people have also reported this issue when using the two pin "duckhead adaptor" in their MBPs, instead of the earthed three pin cord. It is also a common occurrence when using unearthed "two pin" power adaptors in a variety of PC notebooks.
It also happens with Dells - see http://crave.cnet.co.uk/laptops/0,39029450,49295100,00.htm and, it would seem, reading the comments HERE to HPs , Compaqs, Sonys, Thinkpads etc etc. Seems , in fact to be a common feature of Notebook computers when using 2 pin power adaptors, though the amount of metal that is directly contactable may affect the extent which people noticing it! http://forums.reghardware.co.uk/forum/1/2008/01/18/dellm1530_electicshock/ provides more examples from a wide variety of makers.
You will find further discussion of the matter with respect to MBPs at http://discussions.apple.com/thread.jspa?messageID=11031457#11031457
As long as the place where you are using your computer has a proper earth you should be able to overcome the problem altogether by using the power cord with the three pin , earthed, plug, rather than the two pin plug that lets you connect the power block itself directly into a powerpoint.
In summary, I wouldn't be unduly worried about either of your issues, though the "shock" issue can be unpleasant and annoying. I avoid it myself by always using the power cord with the earthed three pin plug, which resolves it completely as long as the wiring in your building is properly hooked up!

Static electric on the new iPad when charging

When I'm charging the new iPad, touching on the back cover will give static electric. Would it damage the device in long run?

Was gifted an Ipad missing an AC Adapter and cable. Bought new cable and adapter. Made the mistake of buying and using a 5 Volt adapter. Made the mistake of using the Ipad when it was being charged (plugged into the electric outlet). Made the mistake of returning and picking up the Ipad after walking across a rug. Blew out that 5 Volt adapter which no longer would charge another suitable (5 Volt correct) device. Bought 10 Volt adapter which would not charge my Ipad as well.
iOS devices charge of USB specification that means 5 Volts ONLY.
A 10 Volt charger would damage the device.
I believe you are confusing Watts & Volts.
Many USB chargers have a higher amperage (that means they can supply more current, not Volts). That translates to more Watts (overall power output).
It allows iPads to charge faster because they have more battery to fill.
The standard iPad charger is 10Watts (the spec isn't visible on Apple.com, so this is from external sources).
iPhones usually have chargers that supply 5Watts
The safest option…
Use an Apple charger that is rated for the device… as you can see Apple sell 5 Watt & 12 Watt supplies for iPads
http://store.apple.com/us/ipad/ipad-accessories/power (search for iPhone chargers etc).
None of this helps you speedgo, sorry. I don't know if static could cause issues. I would move it to another wall outlet, try other rooms - if it still happens take it to an Apple store & ask them for advice it may also happen at the store if the device or charger is faulty.

How to fix issues related to static electricity

I had my iPad connected to a headphone jack for an external player. There was a small static shock when I touched and unplug it. My iPad mini seems to now be having issues related to static electricity. I am clearly having a issue with the audio output thru the headphones. It works normal until the volume scroller gets to 3/4 up, then there is a very irritating static like noise mixed into the other outgoing sounds.
Also the battery seems to be losing power at twice or three times as fast as before. I've only had it a month and half. Can this be fixed somehow?

Hi
I have Iphne 4s/5.0.1 and I'm also stuck with same problem from last 5 days. I have restored/backup/updated the phone as many times as possible. I have been with Vodafone Customer Care (India) and now everyone knows my problem there, but there is no solution.
I have read and tried most of the solutions provided here. Please help me out.
Problem -
1. 3G / Edge working when restore as new phone
2. 3G / Edge stops working as soon as backup is restored
3. Copied and verified both of the files (8218978e4ab0a48035bb92653145a6be872ea858 (Restored new iphone & Restored backup iphone) have different settings. Replacing part of this file or even complete text of this file, changes the date/time stamp of file and on backup restoration it says "Corrupt backup" and phone restarts.
4. I dont want to Jailbreak the phone
5. Using any third party software to install new APN says "Only One APN can be installed"
6. Profile doesnt show any other APN
Is there any other way to delete this file (com.apple.managedCarrier.plist) or just change the section where in string value is "Portalnmms" to required value "iphone" along with key?
Please help me out.
thanks

Safety over static electricity

Today, I connected my iPod to my laptop, recharging it.
And when I touched iPod accidently, I was shocked by static electricity, and both iPod and the laptop is shut down.
I couldn't turn on the laptop for several minites. Anyway, they still work fine later.
My laptop is IBM Thinkpad T42, and iPod is nano 1GB.
And there is no plastic cover on iPod.
Should this happen? Or should I just keep the plastic cover on it all the time? I'm afaid that they may die completely next time, and I couldn't even get the evidence that iPod has broken my laptop!

Well I just had the Mac guys over and it seems that it's the electricity in the house rather than something wrong with the Mac.. Something for the electrician to take a look at.. Oh, and if u wear slippers or shoes u don't feel it

Can static electricity from a carrying case "blow out" a hard drive?

Can static electricity from a carrying case "blow out" a hard drive?
My one-month old MacBook Pro's hard drive died today. The Apple store employee said a number of things could cause it (like dropping it), but I have taken good care of it (never dropped it). The only thing I can think of is that when I take it out of the sleeve I have for it, sometimes I get a static electricity shock. Could this have blown the hard drive? If so, where can I get a nonstatic electricity case? (I got a new computer today.) Thanks!

It's quite unlikely that static electricity would affect the HDD. You may just have had a defective drive or there was some other event that damaged the drive such as leaving the computer running while in your carrying case or doing an abnormal shutdown or an electrical surge when it was connected to the AC adaptor, for example.

Static Electricity causing Aluminum Shelled Notebooks to freeze??

Once in awhile, when I come back to my computer, I get "shocked" by the aluminum body of my MacBook Pro (just for the record, this has happened to me too since the Titanium and the previous [same design] Powerbook) .... and it'll freeze the OS.
Nothing moves, and I have to hard restart.
Does this happen to anyone else? It seems like it happens when the static discharges on the trackpad.
What is up with this???

When using my PowerBook G4, I sometimes feel the zap of static electricity when I first touch it...and if my finger was close enough to the trackpad, the zap 'stuns' the trackpad for several seconds. It's difficult to move the cursor very far. After several seconds the responsiveness returns and everything is normal. This is with the factory power supply and either the two prong adapter or cable with grounded plug.
Also my Mac Pro (and my previous machine, a PowerMac G5) seems susceptible to static. Apparently my desk chair builds up a charge when I'm sitting at the computer for long periods and if I put the computer to sleep and then get out of the chair, the computer wakes back up. My G5 did the exact same thing. The other morning it was particularly cold and I draped a shirt over the back of my chair and the static from that woke the computer. As I walked into the room I could feel the shirt crackling and raising the hair on my arm.
The Mac Pro has a grounded plug, but the machine is sitting on a carpeted floor under my desk... I've been wondering if I should find a mat or something to put it on.
Crazy, huh?

Static Electricity Discharge

i just got a new macbook and whenever i put it in its case to travel it builds up a lot of static electricity and i get shocked, when i take it out and touch a metal part (screw or usb port). does this cause damage to the laptop? if so, how could i tell? it is important to note that the computer is off whenever i get shocked.

While a bit of static electric discharge probably won't hurt anything I wouldn't touch any of the I/O ports. There's some screws visible in the case that I'd try to remember to touch before you go plugging something into the USB or such port.
I've not really encountered too much static electricity in my MacBook (too humid in Indiana in the summer I guess) but I remember my PowerBook used to shock me. Never had any trouble with it.

Static electricity from mc700 new brand using 3 prong power cord

hi all ,
since 12 days i brought my macbook pro mc700 unibody , problem i've noticed that while i'm touching the laptop on the edge while the magsafe green and fully charged a static shock for me and for whom else touch it , i'm using my 3 prong power cord and the same thing in diffrent location , home,office and in dealer branch , that's my first time using macbook moving from windows and i'm shocked from first impression regarding MBP.

i went to the dealer in our country and tried the macbook but still the same shocked me and the tech. there ,when i tried to change the magsafe with spare one there it's works without any problem and without electric shock ,i'm thinking about changing the magsafe OR to buy the moshi sticker someone told me it's prevent the static electric shock.

Static Electricity feeling when touching Macbook Pro 13

Ive been experiencing a weird static electricity when I touch the laptop whilst its charging and im touching something else metallic connected to a power supply. if I slide my hand along the palm rest it feels like a vibration.

Been there.
Are you using a properly grounded outlet with all of your gear? If not, try that first.
If you are properly grounded, you may find that you have a problem at your physical location with respect to grounding/earthing/bonding and it should be checked out by a qualified electrician as it could be indicative of a dangerous situation.
In my house the problem was a poor earth-neutral bond, and once corrected by my electrician the shocks went away.

Zen Touch & Static Electric

Yesterday my Zen Touch was charging on the kitchen counter. When I reached over to touch it, I got a slight shock from static electricity. I was standing on a run at the time. Anyway, my Zen wouldn't turn on but the light on the power button glowed a steady blue. I'd never seen that before. Usually, the power light only glows steady when it's on and flashes when charging. I reset it using the pin hole and everything was fine. It's not anything I'm really cocerned with, since it was easily fixed with a reset. Just thought I'd mention it in case anyone else has the same experience.
Anyone else out there ever have that happen?
Sube

Believe it or not, the static charge generated just by walking across carpet in your house can be upwards of 34,000 volts. The charge depends upon things like relati've humidity and temperature.
It takes far less electrostatic voltage to damage the things in your player, like chips and circuits.
Because I am in a job where I learned that (and much more :P ) trivia regarding electricity, I am in the habit of grounding myself (i.e. - touching metal) before touching anything electronic.
Now, it is fairly unlikely that any voltage would get into the circuitry in your player, but if you love your Zen like I love mine, precautions are never bad.

STATIC ELECTRICITY

just wondering if anyone has ever heard of a person who the minute she goes near a computer, it freezes up. she thinks its because of some type of energy level, static electricity or some other reason

Some people do produce more static electricity than others.
But zapping a computer by getting near it would be an extremely rare event. And you says this has happened more than once.
I think we'd need more details about the computer and the person. It seems more likely a co-incidence, or something else about that person's technique in using computers.
(Some people are extremely ham-handed when it comes to technology. I recall one secretary who grew up on typewriters and never could master the difference between the Backspace key and the Enter key on a PC, because both had an arrow on them. Needless to say, interchanging these keys at random produced a very uneven work product.)

Static Electricity Shuts Off Pla

I pretty much can't use my Creative MuVo V00 this time of year because every time I touch something, static electricity causes it to shut down.

well if i were you, i would by the muvo v00 wriststrap/cade and put the case on [armband can be taken off] because its made of a rubbery material and should protect your player from static

Frequent static electricity from my iPhone 6

I kept getting static electricity from my iPhone 6, just holding it on its own (ie not whilst charging the battery) as I type my texts or browsing the Internet. It hasn't got a casing on. Is this normal? It's happening quite frequently, and it's quite disturbing.

HI
I contacted Apple & did as below as advised & I got my contacts back.
Before I started I made sure that I had a Icloud backup for my IPhone ( which was before the problem started ).[ Settings > ICloud > Backup. ]
IPhone reset - by 'Erase all contents & settings...
after the phone starts, choose to restore from Icloud backup.. & choose the Backup you think is without the issue.
VERY IMPORTANT.. Once the phone restores from the backup & the Home screen comes, put the phone in Airplane mode Immediately.
Now go to settings > Icloud > put the contacts OFF. ( Keep the contacts )
Now OFF the Airplane mode & go to settings > Icloud > put the contacts ON & select Merge.
I got all my contacts back which was there until that Backup.
Thanks again - Apple support.

How can I protect my MacBookPro from static electricity in my house?

How can I protect my MacBookPro from static electricity in my house?

I would not worry about that.
I woud sorry more about power surges (not a grave risk unless your power in your house is twitchy) and water/soda on the keyboard or dropping.
