Can static electricity harm my iMac?

I just moved into a new house and now have a new problem: static electricty. Almost everytime I come to sit at my desk and touch the computer, mouse or keyboard, I feel a small electric shock. Sometime, I even see a spark. Last night, while plugging in a USB device, I saw and heard a spark between the USB cable and the USB port. I got a little worried I might have zapped something inside the computer because this is what happened once with a digital camera.
It never happened to me in the previous house which had hardwood floors. This house has laminate flooring. I don't know if this could be the cause. Anyway, does anybody know if sparks like this can harm the computer or hard drive in any way?

Your Mac's case is grounded so it cannot be harmed by carpet shocks. If it were not properly grounded you probably would not get a spark, so that's a good thing.
Your new house may just be in a dryer location. Consider installing a whole house humidifier - they are not terribly expensive.
It is also possible that your last house's electrical wiring was not correct. Not your problem any more

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.

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.

PLEASE HELP! How can I tell if my Imac has been hacked?

PLEASE HELP! How can I tell if my Imac has been hacked? I see a few people have asked this question but the responses tended to be advice on what to do once you've been hacked, not what can done to find out if you have been hacked. I have a late 2012 model imac. My sharing was off and remote logging was off. I use an external router that send wireless to about 4 consoles in the flat. I don't think I have any firewalls up (now looking like a mistake). I think I'm possibly being hacked due to abnormal behaviour and most recently my camera was turned off all day (no LED) then I went to record something on Photo Booth, the application popped up displaying an image of me getting dressed (nightmare!) which happened hours earlier when the camera was off. This image quickly then disappeared and the camera began working normally. Very strange and alarming. Please help me. Any advice would be very much appreciated. Thanks.

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
Don't be put off merely by the seeming complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. All it does is to collect information about the state of the computer. That information goes nowhere unless you choose to share it. However, you should be cautious about running any kind of program (not just a shell script) at the behest of a stranger. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them. Ask for other options.
Here's a summary of what you need to do, if you choose to proceed:
Copy a line of text in this window to the Clipboard.
Paste into the window of another application.
Wait for the test to run. It usually takes a few minutes.
Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
4. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
5. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
6. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
7. Launch the built-in Terminal application in any of the following ways:
Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
8. If you see an error message in the Terminal window such as "syntax error," enter
exec bash
and press return. Then paste the script again.
9. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
10. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report the results. No harm will be done.
11. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with the words "Start Time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
12. When you post the results, you might see the message, "You have included content in your post that is not permitted." It means that the forum software has misidentified something in the post as a violation of the rules. If that happens, please post the test results on Pastebin, then post a link here to the page you created.
Note: This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

Usage of static electricity cleaner / brusher?

Hi,
I would like to ask if using a static electricity cleaner / brusher to remove dust would affect the iphone? I would usually turn the phone off during that.
Thank you!

Hi Japamac,
I live in a cave, but I think I will take your advice and cut back on the frequency. Is there a duster specially made for such? And if so, where can I get one? So, there is some sort of coating on the LCD screen? Thanks for the feedback.
Hi-
Where do you have the display that requires twice a
day cleaning? You're gonna wear it out, or, damaged
the coating on the panel.
Slow down, wipe less frequently, and get a soft LCD
panel dust brush for your all so often cleaning. That
won't harm the coating on the screen.
Here is Apples cleaning advice:

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

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!
Cheers

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.

Is anyone having an issue with their iPhone5 where static electricity is cutting calls and launching music??

I have an iPhone 5. I live in Nebraska where it is cold and dry right now and static electricity is everywhere. I use the the original equipment earpods virtually always for calls. Within the last several weeks I've started to notice if I move around in a vehicle, or move about my office or home while on a call, I will sometimes hear a small hint of static through the headphones and then the phone call cuts off or ends and my music player will start playing a song. COMPLETELY ANNOYING. In doing some testing since the issue started, I have experienced this now without the earphones both using bluetooth devices OR just the phone itself. I hadn't contacted Verizon yet, which is usually my first call since it is a corporate phone, and thought I would try the forum first to see if anyone else is having a similar issue. Thanks in advance for any feedback!

I just started having this yesterday. It's only happened twice, but it's annoying. My wife texted me that she was coming home last night, and it showed up immediately on my iPod Touch but not my iPhone. I opened my iPhone and it soon updated. Worked fine after that. Then just a moment ago today my wife texted me and the same thing happened. I heard my iMac and iPod Touch receive the message but it didn't display on my phone until I opened the phone and it showed up again a little bit thereafter. I suppose I'll send Apple some feedback on this issue.

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

W520 Overly Sensitive to Static Electricity- Return or Repair?

I just got a w520 with baseline configuration except for the 3x3 wireless card. I have upgraded the laptop to 16gb of ram and added a MSATA ssd. I love the laptop except for one issue: any amount of static electricity crashes the laptop. The laptop goes black, often with some quick graphical errors and then reboots.
Simply sliding the laptop across the bed causes it to crash (I can swing it around in air as much as I want). Putting the laptop into the padded (nylon?) sleeve in my backpack will also cause it to crash, even while the laptop is in sleep mode. I have had this issue since I have got the laptop on day one (before any upgrades). I was hoping the issue would resolve itself as a software issue. I have since realized it is a hardware issue I have no control over as it is repeatable even while in bios.
This situation leaves me with a dilemma: Return the laptop and possibly get one from a different model/manufacture, or turn it in for repair.
There is currently a huge thread about the issue and other sudden shut downs with the W520, so others have had the issue. However, given the number of laptops sold, I know most must not be having issues. In that case, sending the laptop in for repair should fix things. However, I have heard that the repair service does little to recreate situational problems and would not see or fix my issue, so I would be better off sending the laptop in as a return. However, a return might cost me some additional money and would surely take longer given the long lead times for the W520. Anyone have advice on what to do or any fixes?
Its unacceptable that my laptop has issues right out of the box.

Return it.
One thing about spending money wisely is to spend it on things that gives you the least problem, especially right out of the box.
If you spend it on a laptop that's already having issue straight up, why should you spend even more time on it to rectify the issue instead of having the manufacturer dealing with it? Money should be spent on things that are problem-free (as much as possible). Money should not go to something or someone (a company, in this case) that doesn't work right.
While my W520 is working fine now, I do feel your pain. I've gone through similar headache (not the same issue) with two W510.
Lenovo might try to charge you for a re-stocking fee, but they SHOULD NOT. It's as simple as Lenovo didn't provide you with a fully functional and stable product.
Let Lenovo know the issue is that they are incapable of producing products with high consistency of quality control, with low tolerant margin. It may be a tech design issue, it may be departmental polical issue (e.g. QA doesn't think a certain level of test is needed), might be a cost issue (too expensive to fully test every system), might even be a case of workers are working long hours...
Whatever it may be, it's an issue on Lenovo's end, not yours. it shouldn't become your problem, the customer's problem.

Static Electricity coming from all parts of the laptop

I plugged my laptop to my usb printer and i noticed there was occasional static electricity emitting from all parts of the laptop except the touchpad and the keyboards. Its freaky. And it was strong enough for me to feel through my bare hands. My MBP was on battery and not charging at that moment. What should I do? Is it a malfunction? PS: I live in Singapore where it is humid and I dont have carpeting so it is not rubbed static.

Welcome to Apple Discussions!
Does it happen if youtouch your desk before touching your computer?
Does it happen if you connect your computer to a three prong outlet with the three prong plug that comes with it?
Do you have a surge protector or UPS you can connect it to?

How do you fry your mobo w/static electricity?

i recently realigned my motherboard and it worked fine before i did realign it. It's not working at all right now, i can sort of hear it boot up but it won't go to the monitor. Is my video card fried or my mobo? I think it may have been static electricity because i was working on carpet X( DOH! So i want to have my computer back, please help.

Your PSU only has 20A rating on the 3.3VDC rail; for 1GB RAM plus a video card, this is clearly too low, and might be the problem, providing that you haven't fried something already, and something that can happen with a too-low rated PSU even without static electricity.
See my sig for what I run; you should have a supply that's rated 30% or better than your peak usage. Some people run Antec's 430W supply. I recommend no less than the Antec True480. Most people don't realize that the computer is only as good as the power it receives, and skimp on the PSU because it has no "bells and whistles." It's actually the most critical component.
I use the True550 because it can supply 530W independently to the three most important rails, +5, +12, and +3.3. It also gives me plenty of room for upgrades/additions. A bit pricey for power supplies, it, along with a good static kit, is STILL the cheapest insurance to guarantee nothing goes wrong when building/upgrading a new system.

Static electricity while charging iPhone 5

I get static electricity when i charge my iPhone 5 and hold it other people can feel it when they touch my skin it´s like the skin is buzzing, is this something normal.

It's not static electricity. It's a badly grounded outlet. It's harmless. Try plugging your charger into a different outlet or into a surge protector.

Static electricity on metallic surface while charging Satellite P

When my laptop is charging I can feel some static electricity on the metallic surface. In the beginning when i got the laptop it was very little, but now it is so much that you can feel it though another person.
any one knows about this problem.

Usually this small tingling appears due to contact electricity using 2pin AC adaptor,
Using an *3pin* AC adaptor should eliminate such tingling issue
