MacBook not charging. Charging light blinks red and green (very low) than green in normal charge.

My MacBook's battery is dead. When I plug the charge the charging indicator blinks with dim red and green light instead of bright green light. Please help anyone has a solution to it. Last time I remember tye battery was 46%. I plugged in charger and put my iPhone and power bank in charge in Mac USBs. After hours I found that neither phone and power bank was charged nor Mac. Instead Mac's battery was also empty.

Hi harry.ptk,
Welcome to the Apple Support Communities! I understand that you are experiencing issues charging your MacBook Pro. The following resource may provides steps for these sort of issues:
OS X Yosemite: If your battery won’t charge
http://support.apple.com/kb/PH18601
- Reset the battery:
If you have a Mac with a removable battery, remove it and install it again, to make sure it’s properly installed. Refer to the manual that came with your Mac for more information about properly installing the battery.
- Reset the SMC:
Reset the System Management Controller (SMC), which controls how your Mac manages power. For more information, see the Apple Support article Resetting the System Management Controller (SMC).
- Get your Mac serviced:
If the battery still won’t charge, your Mac may need to be serviced. Take your Mac to your local Apple Store or contact AppleCare.

    I recently bought a classic 5th 30gb with 'very low battery'. After 12hrs charging its still same and randomly shows a white screen with this website. Does the battery need replaced or something else is wrong?

    What do you see on the iPod screen, when you plug in to the PC?
    My suggestions,
    Charge only using High Power USB2.0 port at the back of your PC and not the low power USB 1.1 port at the front of the PC.
    Change the USB cable, (maybe it is broken)
    Try a wall charger.
    Have a nice day!

    Yes if your model MBP has a removable battery.  If it does not: 
    Shut down the computer.
    Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
    On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
    Release all the keys and the power button at the same time.
    Press the power button to turn on the computer. 
    Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

    1) Make sure you have Blackberry Desktop Manager installed. BlackBerry desktop software
    2) On your PC, go to Start > Run and copy and paste the following line exactly (meaning with the quotation marks):
    "c:\program files\common files\research in motion\apploader\loader.exe" /nojvm
    3) The Application Loader Wizard will appear -- click "Next."
    4) In the "Connection:" drop-down menu, you should see "USB-PIN: UNKNOWN". Click the "Next" button.
    5) You should then see a list of applications ready to be installed for your Blackberry. Hit Next and Finish and you are well on your way to getting your Blackberry back to life. Congrats! Just don't disconnect anything and let the lengthy process finish completely.
    NOTE: If you do not see a list of applications mentioned in step 5 and instead see the message "The Blackberry Desktop Software does not have Blackberry Device Software for the device that you have connected to the computer. Contact your wireless service provider or system administrator," then you must download Blackberry's Operating System for your carrier and device.  BlackBerry Software Download Site
    Just select the appropriate carrier and network type, select your Blackberry model from the list and download the latest version. Install this download and follow the above steps again and you should be on the right path.

    See the not-charging topic of:
    iPod touch: Hardware troubleshooting
    Have you tried another cable?
    Another charging source? Does iTunes see the iPod when you connect to your computer?
    Look at the dock connector on the iPod. Look for abnormalities like bent or corroded contacts, foreign material and cracked or broken plastic.
    - An appointment at the Genius Bar of an Apple store might be in order

  • MacBook Pro won't turn on after crash. Magsafe charger LED light blinking rapidly

    Hi. I hope you can help me.
    I have a macbook Pro 13", from september 2012, which crashed earlier today:
    I was charging my iphone through USBport on my macbook (not an Apple USB-iPhone power-cable) .
    My MacBook was charging through the magsafe charger (about 30% power i think).
    I took the phone out to make a call, when that was done, I reconnected the phone to my mac for further charging.
    My MacBook crashed instantly. I took out the USB cable, tried to turn on my mac, but nothing happened. There was no light in the magsafe LED.
    The crashing has happened before, when I've been charging my phone through USB connections, but I've always been able to turn my mac back on.
    This time nothing happened when I pushed the power button. It had comepletely shorted out.
    BTW. Earlier today I received a "storage almost full" warning on my mac, and I was actually in the middle of cleaning that up (deleting downloads and trash files).
    Typical and just my luck!
    Now, a few hours later, I tried restoring SMC (shift+ctrl+alt+power), and now the charger LED is blinking rapidly (but faintly) orange.
    Do you have any ideas on how to fix this? All applestores nearby are closed today, I live in Denmark.
    Thank you so much in advance!
    Kind regards Emilie

    Try the SMC reset again:

    Then try a NVRAM reset:
    https://support.apple.com/en-us/HT204063
    Then try a safe boot:

    If no success, then you will have to take it in for service.
    Ciao.

  • Charger light blinking orange and computer won't start up

    My charger on my computer broke a couple days ago so I ordered a new one. While waiting for the battery to come in the mail, the battery on my computer went dead. Now I have the new charger and when I plug it into the computer it blinks orange but never gets a solid orange. Also, the computer will not fire up. Years ago I drained my battery dead and it took a little while charging before it fired back up. I'm hoping its the same problem but it has been over a hour now and still nothing. Anyone have any advise? Thanks

    I just came back from the Apple Store.  They think that the Logic Board is the issue and possibly other issues (They didn't say what).
    Below is a chart of what they will charge me to fix it.  This includes any defective parts, a 90 day warranty and re-imaging the machine I am told.  This is far less expensive than I can do it myself for.  I can't even find a logic board that is in stock for less than $449.
    I will update you if this changes.  I strongly encourage you to goto your local Apple Store and work with them and most of all be polite.

  • HP Pavillion G6 laptop wont turn on or charge - battery light blinks three times - SOLVED

    Ok So I was using my laptop on a regular basis. I shut it down the night prior by using the start shut down menu option. The next morning I went to turn it on and nothing. I did though see the side white light by the Ac adaptor plug in blink three times. I decided to purchase a new charger via ebay(8.99). I plugged it in and nothing. So i started reading different threads to help me fix this issue. I did not see,read  or find anything that truly helped me figure out what it could be so upon further research  I came across this link in the HP site:  http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&dlc=en&docname=c01732674&lc=en&product=5242926&tmp...  This helped me figure out what the light meant.. Hopefully it can help others who may have this same issue.
    So bottom line I did a battery reset. I unplugged every thing from my laptop(battery charger, mouse, etc) I took my battery out of the computer, (pushed in the circle black rubber button (on the back left of my laptop where the seam is) then held down the power button for about 30 seconds then put my battery back into my laptop plugged my new charger in and thus far the battery is charging and the white light is staying on to show a current charging in progress.. Hope this helps anyone else!  

    Try removing the battery and start it up that way and also do a hard reset which means remove the battery and with no AC adapter connected hold down the power button 30 seconds. Now plug in the adapter and try to fire it up. Yes, the battery can go so dead it keeps the laptop from turning on. It is not common however and quite the longshot. It could possibly even be the AC adapter. Do you have access to another known good one? Lastly, it can be the power jack and even the motherboard. It is really not good for a computer to experience repeated hard power-down shutoffs. If you want to kill a computer that is one good way to do it slowly and painfully. The power jack is a separate part from the motherboard and on a scale of 1-10 with 1 being replace the battery and 10 being replace the motherboard it is about a 6 or a 7. No soldering is required. This is the part you need:

    A computer repair shop wil likely charge about $100 for the repair.

  • I tried to update my ipod 4th gen. but when I came to see how much charge the screen was red and it wasnt charged and i cant use my ipod. the screen turned blue also one time, and now the apple logo comes up and its bright then dim and it stays there help

    I tried to update my iPod 4th generation while it was charging and when I came back to check on it the screen was red and it wouldnt go off, and my ipod wasnt charging like it was supposed to. I found out how to get the color of the screen off but my ipod always has the low battery thing and when I charge it sometimes the screen turns blue or the apple logo comes up bright and then it gets dim and stays there. My ipod wont turn on, and I really want it to work again. Help me please! Also, I noticed my ipod battery hasnt been lasting long as it should efore this happened.

    Try:
    - iOS: Not responding or does not turn on
    - If not successful and you can't fully turn the iPod fully off, let the battery fully drain. After charging for an least an hour try the above again.
    - If still not successful that indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

  • Officejet 7000 network not recognized. Lights blink at printer connection and then go out

    I plug in the network cable and the lights blink and then go out. The connection to the router is not established

    Ok,
    First, unplug both the printer and the router power for 30 seconds and check for any change,
    if the same persists, try plugging the ethernet cable from your printer to your PC and check if the same behavior occours.
    If so, than it seems like the printer eternet card is damaged, which will require service
    If it is connecting with your PC, so the issue may be related with your router,

  • Blackberry Curve 9220 Won't Switch stuck On only red light blinking RED LIGHT! HELP!

    Hi and Welcome to the Community!
    Please try this sequence...note that, throughout the entire 4h15m process, your BB must remain directly connected to a known-good wall charger (not PC USB, not a cradle):
    With the battery inside, connect your BB to the wall charger
    Leave it alone for 2 hours, no matter what the LED or the display does
    Remove the battery
    Wait 15 minutes
    Insert the battery
    Wait another 2 hours, no matter what the LED or the display does
    This has been known to "kick start" some BBs.
    It is also possible that your battery or BB has experienced a problem...to test, this sequence is needed:
    Obtain an known good and already fully charged additional battery...use it in your BB and see what happens
    Obtain access to a known good and identical BB...use your battery in it and see what happens
    The results of this will indicate if it's your BB or your battery that has the problem. Note carefully please that "new" and "know good" are not necessarily the same things. While rare, a "new" battery certainly could be defective. Rather, the simplest (and least costly, btw) method to conduct this test is to find someone with an identical BB who has no issues...trade batteries and see what happens.
    Good luck and let us know!
