Adapter light stays on even after removing from MacBook Pro

Hi,
I have a MacBook Pro. I noticed something odd last night. When I remove the adapter from the MacBook Pro (you know, the magnetic end that attaches to the MacBook Pro), the light on the adapter still stays green/on. I actually have to unplug the adapter from the wall outlet to make the light turn off. This never happened before.
Has anyone seen this before? Any advice?
Thanks.

I think that the light is controlled by the middle pin in the connector. Check it very carefully with a magnifying glass to see if any of the pins are bent or if there is any metalic dust in there.

Application which was removed from MacBook Pro Dock will not open. Why?

I dragged the Photoshop Elements (PSE) 11 Editor icon from the Dock on my MacBook Pro (Mavericks) because I had recently installed PSE 13. I still wanted to keep the version 11 Editor but not in the Dock. It dissolved in a puff of smoke as expected. When I went to Launchpad and the Applications folder in the Dock, PSE 11 Editor would not open. There was a question mark over PSE 11 Editor icon in Launchpad. The error message was that there were parts missing and I should reinstall it. When I go to Finder > Applications and click on PSE 11, where the icon used to be is a blank icon. It is named "Alias." When I click on the icon, the error message is "The operation can't be completed because the original item for "Adobe Photoshop Element 11" can't be found." I then when back to Launchpad and opened the PSE 11 Organizer icon. After it opened it, I opened the PSE 11 Editor from the Organizer. The Editor was fine and was functional. I then saved it to the Dock. I went back to Finder and the PSE 11 Editor is still not available. What the heck is going on??? I would like to be able to remove Apps from the Dock and still be able to open them from Launchpad or the Applications Folder. HELP!
Thanks, Bob

"The PSE 11 Editor I restored to the Dock from PSE 11 Organizer today works also."
Yes, sometimes that's all it takes. It's usually a matter of finding the original application nor the alias.
I'm still suspicious of Adobe since they seem to be going the way of Microsoft. If you muck about w/ the folders the application often stops working:
"___ __ cannot open because elements are missing from the application folder".

IPad disabled. Can't restore even after removed from FindMyPhone. Still getting message to remove from FindMyPhone when try to restore. Help!

My iPad indicates that it is disabled. When I try to backup from my PC, it tells me to disable FindMyPhone. I removed the device from FindMyPhone (couldn't see how to turn it off in iCloud) but, when I return to iTunes, it continues to tell me to turnoff FindMyPhone. I've verified the iPad isn't showing on FindMyPhone anymore. What do I do to get into my iPad? Please help!

apple ID does not allow me to change primary listed email address, this address does no longer exist and now need to get a secendary listed email address to become primery.

I had a similar problem, which prevented me changing my personal data on iCloud/apple etc. I found the answer on the apple web-site, "appleid.apple.com".
This site lets you change your primary country, and so lets you use the app store.

N8 charging light stays on, even with leads remove...

If I connect my N8 to my PC with the USB cable, the charging light stays on even after the cable has been removed. See this pic: http://img815.imageshack.us/i/imgp2508k.jpg/
I have to reboot the phone to get the light to turn off.

Can't delete a file displayed in ListView ("File in use") even after removing it from window.

I have a ListView displaying a collection of icons. The user can then select different icons (checkboxes) to do things like Copy or Delete.
Problem is, when I try to delete the actual file from the disk, I get an error telling me the file is "in use" ("vshost.exe", the VS runtime during testing).
I thought maybe it was because it still appeared in the window and was still in the ImageList, but even after removing it from both locations, I still get the error. My code:
Dim intCnt As Integer = 0
Do
ImageList2.Images.RemoveAt(intIconsChecked(intCnt)) ' Remove from collection.
lsvCollection.Items.RemoveAt(intIconsChecked(intCnt)) ' Remove from ListView window.
FileIO.FileSystem.DeleteFile(strIconPath & "\Icon" & Format(intCnt + 1, "00") & ".rsc") ' "+1" b/c Icons start with "01".
FileIO.FileSystem.DeleteFile(strIconPath & "\Icon" & Format(intCnt + 1, "00") & ".png") ' "In use" Error here.
".rsc" deletes just fine, so I know I'm deleting the correct file. Why does VS still think the file is still "in use"?
Thx

Mugsy,
Consider this as food for thought, even if you don't use it.
If you set it up right then you can control how it works. A reference is a reference and any left behind will cause you grief down the road when you try to delete things.
As an example, a simple class follows. It does *not* implement IDispose, although it does have a private shared Dispose method in it:
Public Class MyImages
Private _bmp As Bitmap
Private _name As String
Private _sourceFilePath As String
Private Sub New(ByVal bmp As Bitmap, _
ByVal name As String, _
ByVal filePath As String)
_bmp = bmp
_sourceFilePath = filePath.Trim
_name = name.Trim
End Sub
Public ReadOnly Property Bmp As Bitmap
Get
Return _bmp
End Get
End Property
Public ReadOnly Property Name As String
Get
Return _name
End Get
End Property
Public ReadOnly Property SourceFilePath As String

Return _sourceFilePath

When you look through that, look specifically at the "Remove" method and in particular, look at the order in which things are done. That's the critical part in this.
I tested it with a simple form:
Two buttons, a checkbox, and a picturebox. I also copied a small folder full of image files to my desktop since I'll be deleting a file from it. Following is the code for Form1:
Option Strict On
Option Explicit On
Option Infer Off
Imports System.IO.Path
Public Class Form1
Private miList As New List(Of MyImages)
Private Sub Form1_Load(ByVal sender As System.Object, _
ByVal e As System.EventArgs) _
Handles MyBase.Load
Dim desktop As String = _
My.Computer.FileSystem.SpecialDirectories.Desktop
Dim imgFolder As String = _
Combine(desktop, "Images")
PictureBox1.BorderStyle = BorderStyle.FixedSingle
For Each imgFilePath As String In My.Computer.FileSystem.GetFiles(imgFolder)
MyImages.AddNew(miList, imgFilePath)
Next
btn_RemoveFirstImage.Enabled = False
CheckBox_RemoveSourcePath.Enabled = False
End Sub
Private Sub btn_ShowFirstImage_Click(sender As System.Object, _
e As System.EventArgs) _
Handles btn_ShowFirstImage.Click
Try
If miList.Count >= 1 Then
With PictureBox1
.SizeMode = PictureBoxSizeMode.Zoom
.Image = miList(0).Bmp
End With
btn_RemoveFirstImage.Enabled = True
CheckBox_RemoveSourcePath.Enabled = True
End If
Catch ex As Exception
MessageBox.Show(String.Format("An exception was thrown:{0}{0}{1}", vbCrLf, ex.Message), _
"Exception", MessageBoxButtons.OK, MessageBoxIcon.Warning)
End Try
End Sub
Private Sub btn_RemoveFirstImage_Click(sender As System.Object, _
e As System.EventArgs) _
Handles btn_RemoveFirstImage.Click
Try
If miList.Count >= 1 Then
MyImages.Remove(miList, miList(0).SourceFilePath, CheckBox_RemoveSourcePath.Checked)
End If
PictureBox1.Image = Nothing
btn_RemoveFirstImage.Enabled = True
CheckBox_RemoveSourcePath.Enabled = True
Catch ex As Exception
MessageBox.Show(String.Format("An exception was thrown:{0}{0}{1}", vbCrLf, ex.Message), _
"Exception", MessageBoxButtons.OK, MessageBoxIcon.Warning)
End Try
End Sub
End Class
Running it is straightforward:
Now when I click to show the first one:
A different image is shown because that first one no longer exists - either in the collection or in the folder.
Closing/disposing all references is the key and the order matters.
Something to consider the next time around. :)
Still lost in code, just at a little higher level.

Adapter light stays on all the time...

My battery stopped charging on my MacBook a couple of weeks ago and since then it's had it's DC Inboard replaced, logic board replaced and battery replaced.
When I first got home with it last night the adapter was not working - just showed that it was plugged in but not charging - dh has a MBP and my adapter didn't work with his either and his power cord worked fine on my computer.
Today - tried my adapter again and it worked - but light stayed green even when it was charging - unplugged from my computer and the light stayed on, unplugged from the wall and the light still stayed on for a bit. Plugged it in again, didn't work at all. Plugged it in again with three prong into wall and it worked - is charging with amber light on right now however, when I unplug it from my computer the amber light just stays on. Also - my battery is 100% and the amber light did not change to green, said that it was still charging?
Am I making any sense at all? Do I need to get a new adapter or what the heck is going on now???
Thanks for any help you can offer.

The problem was the adapter itself - got it replaced and have had no problems!

Hello. Today, I was updating my iPod Touch 4th Generation to iOS 6. I unplugged the iPod when it was during the installation because it appeared to be frozen. Now the iPod is stuck at a light blue screen even after I reset it. How do I fix it?

You will need to do a DFU restore by holding the home and power buttons down (while the device is plugged in to your computer) until the device's screen goes black and as soon as the screen goes black, count down from 3 and release the power/sleep button, but keep holding down the home button. Then, iTunes will say the iPod needs to be restored. The restore process will take some time and even though the iPod may appear to be frozen, don't interrupt the restore.

After my 2011 MacBook Pro 17 died, I had to purchase a new MacBook Pro 15 to replace it.

I tried to remove Trovi from macbook pro but it doesnt go away

I tried to remove Trovi from macbook pro but it does not go away. Trovi opens right away

How to remove Trovi adware from Mac - MacSecurity
Helpful Links Regarding Malware Problems
If you are having an immediate problem with ads popping up see The Safe Mac » Adware Removal Guide and AdwareMedic.
Open Safari, select Preferences from the Safari menu. Click on Extensions icon in the toolbar. Disable all Extensions. If this stops your problem, then re-enable them one by one until the problem returns. Now remove that extension as it is causing the problem.
The following comes from user stevejobsfan0123. I have made minor changes to adapt to this presentation.
Fix Some Browser Pop-ups That Take Over Safari.
Common pop-ups include a message saying the government has seized your computer and you must pay to have it released (often called "Moneypak"), or a phony message saying that your computer has been infected, and you need to call a tech support number (sometimes claiming to be Apple) to get it resolved. First, understand that these pop-ups are not caused by a virus and your computer has not been affected. This "hijack" is limited to your web browser. Also understand that these messages are scams, so do not pay any money, call the listed number, or provide any personal information. This article will outline the solution to dismiss the pop-up.
Quit Safari
Usually, these pop-ups will not go away by either clicking "OK" or "Cancel." Furthermore, several menus in the menu bar may become disabled and show in gray, including the option to quit Safari. You will likely have to force quit Safari. To do this, press Command + option + esc, select Safari, and press Force Quit.
Relaunch Safari
If you relaunch Safari, the page will reopen. To prevent this from happening, hold down the 'Shift' key while opening Safari. This will prevent windows from the last time Safari was running from reopening.
This will not work in all cases. The shift key must be held at the right time, and in some cases, even if done correctly, the window reappears. In these circumstances, after force quitting Safari, turn off Wi-Fi or disconnect Ethernet, depending on how you connect to the Internet. Then relaunch Safari normally. It will try to reload the malicious webpage, but without a connection, it won't be able to. Navigate away from that page by entering a different URL, i.e. www.apple.com, and trying to load it. Now you can reconnect to the Internet, and the page you entered will appear rather than the malicious one.
An excellent link to read is Tom Reed's Mac Malware Guide.
Also, visit The XLab FAQs and read Detecting and avoiding malware and spyware.
See these Apple articles:
Mac OS X Snow Leopard and malware detection
OS X Lion- Protect your Mac from malware
OS X Mountain Lion- Protect your Mac from malware
OS X Mavericks- Protect your Mac from malware
About file quarantine in OS X
If you require anti-virus protection Thomas Reed recommends using ClamXAV. (Thank you to Thomas Reed for this recommendation.)
From user Joe Bailey comes this equally useful advice:
The facts are:
1. There is no anti-malware software that can detect 100% of the malware out there.
2. There is no anti-malware that can detect everything targeting the Mac.
3. The very best way to prevent the most attacks is for you as the user to be aware that
     the most successful malware attacks rely on very sophisticated social engineering
     techniques preying on human avarice, ****, and fear.
4. Internet popups saying the FBI, NSA, Microsoft, your ISP has detected malware on
    your computer is intended to entice you to install their malware thinking it is a
    protection against malware.
5. Some of the anti-malware products on the market are worse than the malware
    from which they purport to protect you.
6. Be cautious where you go on the internet.
7. Only download anything from sites you know are safe.
8. Avoid links you receive in email, always be suspicious even if you get something
    you think is from a friend, but you were not expecting.
9. If there is any question in your mind, then assume it is malware.
