- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.

Pro won't start. Instead get a black screen and a beeping every 2 seconds. Light at front right corner of keyboard flashes in sequence with beeping.

If it is giving a single beep every two seconds, then it is not seeing any of the memory. You could try taking the back off, remove the memory module and reinsert to see if that corrects the problem. Or just take it to an Apple store genius bar and have the techs do that for you.
If you are uncertain about working on the memory modules, you can find on-line videos for doing so at OWC, http://www.macsales.com where you can see the procedure for your year, make and model of MacBook Pro.

X230 Win 8.1 Pro Fingerprint single swipe power on and login black screen

When i try to log on using the single swipe power on and login feature sometimes the screen will go to the login screen, the finger print scanner will flash, and then i get a black screen. I can see the mouse cursor, but nothing else. If I swipe my finger again, I will see the login screen again briefly, before it returns to a blank screen again. There is no way to get past this, aside from forcing the machine to power down (Hold down power key for 10 seconds).
Does anyone have a solution for this. Powering on the device and logging in with a single swipe is a really great feature, but I need it to not brick logging in.
Thanks for any help or advice.

I apologize I didn't already provide these answers initially.
Questions:1. Does this happen 100% of the time, or is it intermittent?
I have only noticed this intermittently.
2. Does it happen starting from full shutdown (press and hold SHIFT key while you shutdown the computer normally, then swipe to power on and log in).
I have only had this problem when resuming from a state of hibernation.
3. Does it happen starting from sleep (swipe to resume the system from sleep and log in)
I rarely sleep the system, but I recall it hanging once or twice when coming back from sleep as well.
4. Can you check "View all problem reports" screen in Action Center to see if any crash happens at the same time the problem occurs?
the only problem reports that corresponds with the times this has happened today refer to an problem with the Anti malware Service Executable with the summary being MpTelemetry.
5. Can you export registry at these locations:
a. [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Authentication\Credential Provider Filters]
b. [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Authentication\Credential Providers]
I have this, but unfortunately do not see how I can attach it this post.
Edit: Here is a link to download it directly. Once you respond I'll disable this.
Link removed
It should also be noted that I do not have a problem when single swipe is disabled. (So I need to swipe twice. One to power on, and the other to log in.)

Power Button Displays a Black Screen

After upgrading to OS X Mavericks, when I press the power button it displays a black screen. I'm assuming this is sleep mode. Before upgrading, pressing the power button would display a window allowing me to choose whether I wanted to restart, shut down, etc. Is there a way to get this functionality back? Is anybody else having this problem?
Thanks.

This is a feature of Mavericks. If you hit the power button it puts the system to sleep. If you hold the power button for a couple seconds, it will display the menu that you are looking for. Also, due to the ATX compliant hardware, if you hold the power butto for about 10 seconds, it will hard power off the system without performing a clean shutdown.
I am not aware fo any System Preference setting to change the behavior of the power button under Mavericks. There might be a method to control it via a command line setting, but I haven't spent the time to seach for one once I learned that I can just hold the button down for 2 seconds to get the menu.

My iPod displays black & white battery charge icon and sad iPod face. help!

I plugged my iPod into an older iMac; it froze and had to be restarted.
I restarted it and started listening on shuffle.
It would skip through all of my songs without me pressing any buttons.
I restarted again and it worked fine.
I came home and plugged it into my 10.3.9 iMac and the tracks started skiping and barely playing on iTunes.
I tried to eject it, but it wouldn't...so I unplugged it.
I then restarted it, but after the silver-on-black iMac icon came up, the sad iPod face showed.
So I pluged it back into the computer. It spontaniously restarted when I tried all of the steps of restarting and reinstalling.
Then it just displays a black& white old battery charge icon with a thunder bolt that flickers on the screen now and then.
And continues to restart itself with first the apple icon turning into the sad ipod face and then into the battery charge icon.
I really do not want to restore my iPod. I am hoping to keep my files but at this point, my future is bleak.
This happened last night. They said it might just be my battery so I kept it plugged in for about 10 hours. Nothing.
What can I do?
Please, please help.

Hello,
If a sad iPod icon or an exclamation point and folder icon appears on your iPod’s screen, or with sounds of clicking or HD whirring, it is usually the sign of a hard drive problem and you have the power to do something about it now. Your silver bullet of resolving your iPod issue – is to restore your iPod to factory settings.
http://docs.info.apple.com/article.html?artnum=60983
If you're having trouble, try these steps at different levels one at a time until the issue is resolved. These steps will often whip your iPod back into shape.
Make sure you do all the following “TRYs”
A. Try to wait 30 minutes while iPod is charging.
B. Try another FireWire or USB through Dock Connector cable.
C. Try another FireWire or USB port on your computer .
D. Try to disconnect all devices from your computer's FireWire and USB ports.
E. Try to download and install the latest version of iPod software and iTunes
http://www.apple.com/ipod/download/
http://www.apple.com/itunes/download/
F. Try these five steps (known as the five Rs) and it would conquer most iPod issues.
http://www.apple.com/support/ipod/five_rs/
G. Try to put the iPod into Disk Mode if it fails to appear on the desktop
http://docs.info.apple.com/article.html?artnum=93651
If none of these steps address the issue, you may need to go to Intermediate level listed below in logical order. Check from the top of the lists to see if that is what keeping iPod from appearing on your computer in order for doing the Restore.
Intermediate Level
A. Try to connect your iPod with another computer with the iPod updater pre-installed.
B. Still can’t see your iPod, put it in Disk Mode and connect with a computer, instead of doing a Restore on iPod Updater. Go and format the iPod instead.
For Mac computer
1. Open the disk utility, hope your iPod appears there (left hand side), highlight it
2. Go to Tab “Partition”, click either “Delete” or “Partition”, if fails, skip this step and go to 3
3. Go to Tab “Erase” , choose Volume Format as “MAC OS Extended (Journaled), and click Erase, again if fails, skip it and go to 4
4. Same as step 3, but open the “Security Options....” and choose “Zero Out Data” before click Erase. It will take 1 to 2 hours to complete.
5. Eject your iPod and do a Reset
6. Open the iPod Updater and click “Restore”
For Window computer
Go to folder “My Computer”
Hope you can see your iPod there and right click on the iPod
Choose “Format”. Ensure the settings are at “Default” and that “Quick Format” is not checked
Now select “Format”
Eject your iPod and do a Reset
Open the iPod Updater and click “Restore”
In case you do not manage to do a “Format” on a window computer, try to use some 3rd party disk utility software, e.g.“HP USB Disk Storage Format Tool”.
http://discussions.apple.com/thread.jspa?threadID=501330&tstart=0
C. Windows users having trouble with their iPods should locate a Mac user. In many cases when an iPod won't show up on a PC that it will show up on the Mac. Then it can be restored. When the PC user returns to his computer the iPod will be recognized by the PC, reformatted for the PC, and usable again. By the way, it works in reverse too. A Mac user often can get his iPod back by connecting it to a PC and restoring it.
Tips
a. It does not matter whether the format is completed or not, the key is to erase (or partly) the corrupted firmware files on the Hard Drive of the iPod. After that, when the iPod re-connected with a computer, it will be recognized as an fresh external hard drive, it will show up on the iPod updater.
b. It is not a difficult issue for a Mac user to find a window base computer, for a PC user, if they can’t find any Mac user, they can go to a nearest Apple Shop for a favor.
c. You may need to switch around the PC and Mac, try to do several attempts between “Format” and “Restore”

Advance Level
A. Diagnostic mode solution
If you have tried trouble shooting your iPod to no avail after all the steps above, chances are your iPod has a hardware problem. The iPod's built-in Diagnostic Mode is a quick and easy way to determine if you have a "bad" iPod.
You need to restart your iPod before putting it into Diagnostic Mode. Check that your hold switch is off by sliding the switch away from the headphone jack. Toggle it on and off to be safe.
Press and hold the following combination of buttons simultaneously for approximately 10 seconds to reset the iPod.
iPod 1G to 3G: "Menu" and "Play/Pause"
iPod 4G+ (includes Photo, Nano, Video, and Mini): "Menu" and "Select"
The Apple logo will appear and you should feel the hard drive spinning up. Press and hold the following sequence of buttons:
iPod 1G to 3G: "REW", "FFW" and "Select"
iPod 4G+ (includes Photo, Nano, Video, and Mini): "Back" and "Select"
You will hear an audible chirp sound (3G models and higher) and the Apple logo should appear backwards. You are now in Diagnostic Mode. Navigate the list of tests using "REW" and "FFW". The scroll wheel will not function while in diagnostic mode. For further details on Diagnostic mode can be found at http://www.methodshop.com/mp3/ipodsupport/diagnosticmode/
Try to do the 5in1, HDD R/W and HDD scan tests. Some successful cases have been reported after the running the few tests under the Diagnostic mode. In case it does not work in your case, and the scan tests reports show some errors then it proves your iPod has a hardware problem and it needs a repairing service.
B. Format your iPod with a start disk
I have not tried this solution myself, I heard that there were few successful cases that the users managed to get their iPod (you must put your iPod in disk mode before connecting with a computer) mounted by the computer, which was booted by a system startup disk. For Mac, you can use the Disk Utility (on the Tiger OS system disk), for PC user, you can use the window OS system disk. Try to find a way to reformat your iPod, again it does not matter which format (FAT32, NTFS or HFS+) you choose, the key is to erase the corrupted system files on the iPod. Then eject your iPod and do a Reset to switch out from Disk Mode. Reboot your computer at the normal way, connect your iPod back with it, open the iPod updater, and hopefully your iPod will appear there for the Restore.
If none of these steps address the issue, your iPod may need to be repaired.
Consider setting up a mail-in repair for your iPod http://depot.info.apple.com/ipod/
Or visit your local Apple Retail Store http://www.apple.com/retail/
In case your iPod is no longer covered by the warranty and you want to find a second repairing company, you can try iPodResQ at your own risk
http://www.ipodresq.com/index.php
Just in case that you are at the following situation
Your iPod warranty is expired
You don’t want to pay any service charges
You are prepared to buy a new one
You can’t accept the re-sell value of your broken iPod
Rather than leave your iPod as paper-weight or throw it away.
You can try the following, but again, only do it as your last resort and at your own risk.
Warning !!!! – It may or may not manage to solve your problem, and with a risk that you may further damage your iPod, which end up as an expensive paper weight or you need to pay more higher repairing cost. Therefore, please re-consider again whether you want to try the next level
Last Resort Level
1. . Disconnecting the Hard Drive and battery inside the iPod – Warning !! Your iPod warranty will be waived once you open the iPod.
In Hong Kong there are some electronic shops offering an iPod service for Sad iPod, the first thing they do is to open up the iPod’s case and disconnecting the battery and the Hard Drive from the main board of the iPod. Wait for 5-10 minutes and reconnecting them back. The reason behind which I can think of is to do a fully reset of a processor of the iPod. In case you want do it itself and you believe that you are good on fixing the electronics devices and have experience to deal with small bits of electronic parts, then you can read the following of how to open the iPod case for battery and HDD replacement (with Quicktimes)
http://eshop.macsales.com/tech_center/index.cfm?page=Video/directory.html
2.Press the reset button on the Hard Drive inside the iPod – Suggestion from Kill8joy
http://discussions.apple.com/thread.jspa?messageID=2438774#2438774
Have I tried these myself? No, I am afraid to do it myself as I am squeamish about tinkering inside electronic devices, I have few experiences that either I broke the parts (which are normally tiny or fragile) or failed to put the parts back to the main case. Therefore, I agree with suggestion to have it fixed by a Pro.
2. Do a search on Google and some topics on this discussion forum about “Sad iPod”
What should I do with my iPod? Send it or keep it?

Black screen and no illumination on keyboard

My macbook pro now when i press the power button doesnt have any lights come on the keyboard and the screen remains black. The battery indicator lights and the charger light works fine and I can hear the fan, but still the black screen and no illumination. I'm not sure of even the first thing to do as I am still fairly new to Macintosh. The computer isn't new I received it from my mother who hardly used it and had it for just about a year. I would really appreciate any help since this machine has made a huge difference in my student way of life. Thank you in advance for any help or advice. -Jenna

You may have to take the computer to the Apple store to have it checked.

G62-229WM - Battery charges but computer won't start/run on AC power.

I've got an HP G62-229WM, running Win7 Ultimate 64 bit, that will only run on battery power.   With a full, or even partially, charged battery and the AC adapter not plugged in, the computer starts and runs just fine. The little power icon down in the screens taskbar area shows the normal battery only icon and indicates the correct % of charge.
When I plug in the AC adapter (original HP 18.5V 65 watt adapter that came with the unit) the AC adapter light LED (located next to the AC adapter plug-in port) turns white momentarily and then turns amber, which indicates that the battery is charging.   This is supposedly normal.
When the battery reaches 100% charge, the indicator light turns white again, and remains a steady white, which means that the computer is connected to external power, but the power icon in the taskbar area still shows just the battery only icon and not the battery/plug icon. The operating system does not recognize that the computer is connected to external power and thinks that it is running on battery power only.
If I shut down, remove the battery and plug in only the AC adapter and press the power button, nothing happens.   No lights, no fan, no disk spinning, nothing.   The AC adapter seems to charge the battery just fine (and the computer runs fine on the charged battery) but the adapter will not start or run the computer by itself.
I first noticed this problem a couple of days ago when I was on the System Properties page and it said that the "Windows Experience Index" was 6.1 but that the rating needed to be re-assessed.   When I tried to rerun the assessment, it stated that the assessment could not be run on battery power only and that I needed to connect to external power.  Of course, the computer was plugged into AC power at the time which first alerted me to this problem.
Any ideas would be much appreciated.

Hi,
I see that a full charge results in only 51% of the battery capacity. Your battery is going south. It would be great if you happen to know someone with an HP power adapter like yours to plug in to your noetbook. The AC adapter output is within 10% of 18.5 volts so it is OK. I suspect a charging and power management control chip failure on the system board is causing the issue.
Best regards,
erico
