Power cord or hardware

When I plug my power cord in, it charges, but the screen blinks brighter and then duller. The electric charge goes on and off. and off. The light on the bar at the bottom shows the battery and then the plug that it is charging on and off.

I REALLY wish HP would recall this power cord.
The power cord for my HP pavilion dv6700 has not worked properly since the day I bought it, I have the wiggle the cord around to get the blue light to turn on, same as many other owners of this and similar HP Pavilion notebooks. I used to have to keep the cord taped to hold it in the right spot so that it would charge, which is really pathetic. In the past week, it will not recognize the charger at all. Since so many others have had the same issue, I believe the charger is defective. This model is on the recall list for battery issues, but the barcode on my battery was not on the list of recalls. I've read so many other people have replaced the power cord numerous times which works only for a short period of time, so I really don't feel like investing in a new charger only to have it stop working in 2 months. I'm at a total loss of what to do.

Power cords for older hardware?

Hi,
Anyone know where I can get power cords for
a PowerMac G3 (beige short desktop) and
an Apple Multiple Scan 15 AV Display?
Willing to pay a fair price!
Thanks in advance,
--Prahas

The Beige G3 uses a generic , 3-conductor power cord that is available new and for cheap. I believe the monitor uses the same type. Some of the 16 Macs in our family have old power cords salvaged from dead PC computers. They are interchangeable

After reading and resetting everything with Keyboard I still get blank white screen. The only way I can boot to Mavericks is unplug power cord, push and hold power button while plugging power cord in. Fans at full speed.

After reading and resetting everything with Keyboard I still get blank white screen on 2nd? page of boot. The only way I can boot to Mavericks is unplug power cord, push and hold power button while plugging power cord in. Fans run at full speed, machine boots then runs normal except the dvdrw will not . The mid 2011 IMAC had the same problem with LION. I changed hard drives, formatted, and installed a clean install of latest os x mavericks. Any help would be greatly appreciated.

Use the uninstaller provided with the Sophos software. You can uninstall CUDA via the preference pane. Be sure you remove the com.nvidia.CUDA extension which is located in the /System/Library/Extensions/ folder. Not sure if Fan Control has an uninstaller so you will have to do it manually:
Uninstalling Software: The Basics
Most OS X applications are completely self-contained "packages" that can be uninstalled by simply dragging the application to the Trash. Applications may create preference files that are stored in the /Home/Library/Preferences/ folder. Although they do nothing once you delete the associated application, they do take up some disk space. If you want you can look for them in the above location and delete them, too.
Some applications may install an uninstaller program that can be used to remove the application. In some cases the uninstaller may be part of the application's installer, and is invoked by clicking on a Customize button that will appear during the install process.
Some applications may install components in the /Home/Library/Applications Support/ folder. You can also check there to see if the application has created a folder. You can also delete the folder that's in the Applications Support folder. Again, they don't do anything but take up disk space once the application is trashed.
Some applications may install a startupitem or a Log In item. Startupitems are usually installed in the /Library/StartupItems/ folder and less often in the /Home/Library/StartupItems/ folder. Log In Items are set in the Accounts preferences. Open System Preferences, click on the Accounts icon, then click on the LogIn Items tab. Locate the item in the list for the application you want to remove and click on the "-" button to delete it from the list.
Some software use startup daemons or agents that are a new feature of the OS. Look for them in /Library/LaunchAgents/ and /Library/LaunchDaemons/ or in /Home/Library/LaunchAgents/.
If an application installs any other files the best way to track them down is to do a Finder search using the application name or the developer name as the search term. Unfortunately Spotlight will not look in certain folders by default. You can modify Spotlight's behavior or use a third-party search utility, EasyFind, instead.
Some applications install a receipt in the /Library/Receipts/ folder. Usually with the same name as the program or the developer. The item generally has a ".pkg" extension. Be sure you also delete this item as some programs use it to determine if it's already installed.
There are many utilities that can uninstall applications. Here is a selection:
    1. AppZapper
    2. AppDelete
    3. Automaton
    4. Hazel
    5. AppCleaner
    6. CleanApp
    7. iTrash
    8. Amnesia
    9. Uninstaller
10. Spring Cleaning
For more information visit The XLab FAQs and read the FAQ on removing software.
Be sure to remove your two Login Items. Finally do this:
Reinstall Lion, Mountain Lion, or Mavericks without erasing drive
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu.
Reinstall Lion, Mountain Lion, or Mavericks
OS X Mavericks- Reinstall OS X
OS X Mountain Lion- Reinstall OS X
OS X Lion- Reinstall Mac OS X
     Note: You will need an active Internet connection. I suggest using Ethernet
                 if possible because it is three times faster than wireless.

Mag Safe power cord sparks when connected or disconnected--whereupon the MacBook Pro 13'' dumps date and time, and all passwords, plus any/all unsaved information.

I purchased my MacBook Pro 13" from the Apple Store in Tucson, AZ, in mid-January. Since then, every time the Mag-Safe cord is jostled, not even disconnected, sparks fly from the power terminal on the computer, the computer shuts down, and dumps its passwords, as well as the date and time.
Any work in progress is also lost.
I work overseas, and Apple's advice was to give them my credit card number, await shipment of a new power supply and cord, and then, when I return the old power supply and cord, i'd receive a credit. That won't work, as packages from the US to my location take weeks if they arrive at all. There is no Apple Store within a reasonable distance. Or, Apple suggests, when I'm home on leave in mid-June, I should bring the computer to the Apple Store for repair--I have only days in which to do that, but I suppose I'll need to try. My concern is that I'll need to return overseas without my computer and won't be able to retrieve it for months, until my next leave.
This issue shows up elsewhere online. Is there a short in the power terminal in the computer, or on the Mag-Safe power cord, or within the computer itself? It's a known issue, thus I wonder why it hasn't been fixed.

Odd, but here's a copy of Page 1 of the links I got:

Removal of Power cord leads to immediate shutdown despite fully charged bat

Yes,
My 2 week old Reconditioned MacBook Pro 15" 2.33/2gbRAM has started to shut down immediately when i take the power cord out.
I tried the SMC reset procedure 3 times (namely:
1) Turn computer off
2) Disconnect the AC Adapter and remove the computer's battery.
3) Press and hold down the power button for 5 seconds and then release the button.
4) Reconnect the battery and AC Adapter.
5) Press the Power button to restart the computer.)
No joy, still same problem.
What should I do next?
Any help would be most appreciated.
Thanks

I have been having several issues with my MBP (purchased 6-17-06) regarding sleep/shutdown/battery as have many others.
I called Apple Thursday (4-12) and gave tech support all of the following symptoms:
Does not go to sleep when lid is closed.
Sudden shutdown at various levels of available battery power.
Occasional, abnormal trackpad click (loud, hard?).
"Blinks" when woken from sleep to a blank, light blue screen.
Quiet buzz that stops when clicking or dragging the trackpad.
(Note: I do not have the bulging battery as some have mentioned.)
The tech support guy was going to have me zap the P-RAM, but I had already done that, with no effect. So next he had me insert the OSX install disk to repair the HD. There were no problems, so he issued a repair ticket, gave me a dispatch number, and sent out a box. It was on my step Friday and it will go out tomorrow (Mon. 4-16). I was probably on the phone a total of 20 or 30 minutes.
I expect it to be a logic board replacement, but I will update here when I get it back. My MBP will probably be back by Wed. afternoon if this is anything like my other experiences with Apple Care - very fast turnaround.
BTW - He was going to charge me $50 for the tech support, but I said it was a hardware issue, not software and it should not be my expense. He said he would "make a one-time exception" and not charge me this time, but I should really consider extending to the 3-yr Apple Care. I will consider it, but I know it's not right for Apple to try to charge anyone for this problem.
Sorry for going on for so long, but I want to make it clear if anyone is having these problems they should call Apple ASAP. Especially if you are still under warranty. They will/should fix it at their cost.

Edge 540 model : when I connect/disconnect AC power cord, screen goes dark

For the past few days, everytime I connect the power cord, the screen goes dark for a second. The same thing happens when I disconnect the power cord. Can someone help me find out what is wrong with it? Is it a hardware issue or is it just a momentary glitch (It just started happening yesterday)?
My laptop is brand new so I can use the warranty if i have to.
OS: Win 8
Thank you.

this is a normal behaviour it happens all the time. It is your refresh rate changing between different power setting. Set the screen refresh rate at 60 hz for both battery and with ac adapter connected this should prevent the momentary blanking of the lcd.

IBook screen goes black after unplugging power cord

I originally posted this topic in the wrong discussion group for iMac G4, the computer is actually an iBook G4.
My wife's iBook bought about 2 years ago shows battery 100 percent charged. But when she unplugs the power cord the screen goes black. Can not be restarted until she plugs in the power cord. It seems like it might be the battery. She got extra batteries when she bought it. Is there a way to tell if it is the battery before having to replace it?

Did you check on the status of your battery using "About this Mac" under the Apple on the menu bar? Click on "More Info..." and select Power under Hardware. It will tell you capacity and cycle count.
You may have a dead battery.

IMac power cord

I have an iMac I bought in Asia and it has 3 prongs. I brought it here with me when I moved to the US and have been using a plug adapter. It works perfectly fine, no problems at all.
My question is, is it possible to change the power cord with a US one - one that only has 2 prongs?

Yes, you can. Go to any hardware store and see if you can find one. Modern requirement is a 3-prong plug. There are adapters to use with 2-prong outlets that provide a grounding wire for safety.

Any hardware store should have one. It's a standard AC cord with a female connector on one end.

Macbook will not start up with power cord plugged in

hi,
my macbook core duo, wont startup anymore with the power cord.
It does work with a battery though. But the problem is that the cord is not charging the battery anymore and not even giving power to the machine.
the light on the cord is green. I tried with another power cord, it does the same.
i even changed the dc-in board, with no luck.
any ideas ?

I have the exact same problem. There is a buzz from the region where the power connection is, and I'm afraid it is a power hardware issue. Since the optical drive already quit on this first gen MacBook, I think it's time to chuck this lemon.

Boot issue after shutdown plus power - no problem after restart or after removing power cord

Hello,
I have a Pavilion Elite m9275.nl desktop. I experience boot issues after a regular shut down.
After a regular shut down and pressing the power button within a few seconds/minutes, it keeps hanging in the HP startup / BIOS screen, Windows 8 won't boot, the hard drive light doesn't flash;
After a restart from Windows (instead of shut down) it boots correctly from the c-drive. No hard-drive problems at all;
After a shut down and removing the power cord for 10-15 minutes, it boots correctly from the c-drive. No hard-drive problems at all.
When the PC does not boot, F10 (to enter BIOS settings) does not work neither, so it seems to be a hardware or BIOS issue.
I already replaced the CMOS battery and already loaded default BIOS settings.
During a succesful boot or after pressing F10 (to enter BIOS settings) the screen shows some disk information right after the BIOS. This is the screen that says something like "press CTRL-I to start configuration utility". During a succesful boot the hard disk light flashes shortly before displaying that screen. During an unsuccesful boot the hard disk doesn't flash.
Before replacing a hardware component, I need to know what to replace...
Could it be the hard disk controller or hard disk is defect?
Where is the hard disk controller stored?
Can I upgrade the firmware of the hard disk controller?
BUT: why does it work when I remove the power cord for 15 minutes or after a restart (instead of a shutdown and than pressing power)?
Many thanks in advance,
Sjoerd-Jaap Westra

HP ProBook 4530s orange blinking led, won't recognise the power cord

Hello!
yestarday I tried to open my laptop but it didn't start. i thought that maybe the battery was empty so i plugged the power cord, but nothing happened.
then I noticed the led near the power cord blinking orange. After a fast googling i came to this thread ( http://h30434.www3.hp.com/t5/Notebook-Hardware/charging-light-blinking-problem-with-hp-probook-4530s... )
using the 8-step guide I managed to boot the laptop just to realise that it won't detect the power cord!
It was really strange, because when I noticed this, my battery was already at 2%!
I shut down the laptop, and tried to open it without the battery, it booted normally, but it still can't detect that the power cord is plugged in!!!!!
On the other thread some mentioned to update the bios, but in my case where it can't detect the power cord, that's impossible, because the procedure requires the laptop to be plugged in.
Now the laptop won't start normally, I have to keep the power button pressed for 40 secs and then plug the power cord. In addition it won't work only with battery, and that is my biggest problem!!
What should I do now?

Hello @sakisg4 ,
To get your issue more exposure I would suggest posting it in the commercial forums since the HP ProBook 4530s is a commercial product. You can do this here Notebook - HP ProBook, EliteBook, Compaq, Slate/Tablet PC, Armada, LTE
The support page for your product may be helpful in the meantime: HP ProBook 4530s.
I hope this helps!
Thank you for posting on the HP Forums.
