Adaptor to MacBook does not light up

It seems that my MagSafe adaptor is not working

Mine do that from time to time. The acid test is to check the icon in the menu bar. If it says you are charging or the percentage is 95% or greater and you see a electrical plug icon, you are ok. If you see a black battery icon, then the charger is not working. Wiggle the connector and see if it will start functioning again. If not, you may need a new one. If available, try a different one to see if the problem is the power adapter or the MBP.
You may also look at this Apple support article for additional information.

MacBook does not restart after software upgrade without power adaptor

Hi everbody,
I've done a big mistake while updating my macbook without power adaptor plugged...
After having started the installation, I had many other things to do and completely forgot the installation. So I guess the macbook stopped when the battery had no more power.
The problem is that the macbook does not start any longer, with or without the power adaptor. I've tried the different ways to start the macbook described in the faq, but without success. When I plug the power adaptor, there's no signal and the battery remains very low.
So, if someone has a way to restart my macbook, I'd be greatly happy !
Thanks

I've solved my problem by disassembling and reassembling the power supply.

Led Light on MageSafe Charger Does not light;MacBook Air Recognizes it but does not charge

So I've had my MacBook Air (Mid-2011) for over a year now. The reason I am posting this is because I originally had a 40W MagSafe "L" Shape that came with my MacBook Air. Well I accidently spilled Pepsi on it while it was plugged in and you get the gist of that. Well I had bought an 85W "L" Shape adapter and it works perfectly fine, no problems. I've had the 40W stored away for probably 5 months or so and recently got the itch to work on it and try to trouble shoot it. Being an IT student, I get a hunch to just take apart things and try to fix them. But anyway, I've reset the prongs on the L part itself, I've changed the plug in to the 3 prong AC instead of the "Duck Face" thing. I've checked for SMC updates and it told me my MacBook does not need it. Well when I plug in my charger, it is recognized immediately by my MacBook. But on the top where the battery level is, it says "Battery is not Charging" and also says "Power Source: Power Adapter". So I am a little confused as to why it won't charge. I let it dry out when this first happened in some rice but I am not sure that did anything for it. I also have cleaned it, like i said I reset the prongs on the L shaped adapter itself. I haven't on the other hand gone and opened it, just because messing with those adapters and any adapters can lead to you getting shocked regardless. So if anyone has any suggestions let me know, I would like to use this charger as a At home charger or my mobile charger when I go to school. Thanks!

"drying it out" does nothing as per the acid in the soda and sticky corrosive sugar and acid left behind.
Youve gone thru $100 worth of effort in repairing a $60 charger, and plan on more effort.
Either a used charger online would be a cheaper option and better than possibly causing logic board damage to your macbook Air.

MacBook Pro will not start up, get start up chime but screen does not light up. Any help?

Upon start up I hear optical drive checked, then get a start up chime but the screen does not light up. I have shut down by holding down power butto for 10 seconds also pulled battery and A/C power.

I had this same issue but after a new hard drive/ram install.
What solved the issue - and I hope this helps someone else who has the same problem:
1). Install new hard drive (with or without osx pre installed) or leave old one in in your case.
2). Remove all ram
3). Power on and wait 1 minute
4). Hold power button until it turns off
5). Install ram
6). Power back on
7). BOOM! It works again.

HT3964 My Macbook air charges intermittently. At times when I connect the power adapter it shows that power is coming in but says "not charging" and the led light on the power adapter does not light. At other times it charges normally. Any ideas?

Hey guys,
I am having problems with charging my mac Air. Sometimes it charges perfectly but then at times much as it shows that it's getting the power from the charger, it says "not charging" and the led light on the charger does not light up. Any help?
Rgds,

That can happen when you are Taxing the system. No Apple supplied AC adapter supplies enough power to both power the system and charge the battery at the same time when the system is under Heavy Load, when you are Taxing the system heavily. At those times it will draw power from both the AC adapter and the battery at the same time. So if it is drawing power from both it can't charge the battery while it is drawing power from it.

Broken screen (LED does not light up) help

ok..
so i have a macbook 13.3 white.. im pretty good with computers/etc..
So i turn on my macbook and the screen is dark.. but surely the macbook is on.. you can see the screen under bright light shined on the screen.
But the screen does not light up.
So i checked- my brightness settings.. then set power settings to normal.. set it to sleep and woke it up. NOPE.
I bought a new screen and installed it properly. NOPE same thing.
I bought a new power 'inverter'.. NOPE same thing
I bought a LVDS cord (chord connecting screen to the logicboard). NO same thing!
So at this point im real close to throwing it as far as i could from the side of the Golden Gate Bridge =/. but i refuse to.
I KNOW THERE IS A SOLUTION AND SOMEONE OUT THERE TO KNOW!
please help, and thank you much.

Definitely follow this advice. Makes life much easier. As for the code itself, first be aware that you can't just "sh" it. It runs using arguments, so you'd run something like
# ./enlighten increase keyboard
Though I wrote that script for zsh, I believe it should be compatible with bash without issue. Below is a much simpler version of the script which will only increase or decrease the keyboard backlights:
#!/bin/bash
#<- Configuration ->
kbd=/sys/class/leds/toshiba::illumination/brightness
kstep=15
self="$(basename $0)"
#<- Error Handling ->
E_HELP=44
E_PERMS=45

if [ "$UID" != 0 ]; then
echo "$self must be run with root privileges"
exit "$E_PERMS"
fi
usage () {
echo "Usage: $self [-h|--help] <increase|decrease>"
exit "$E_HELP"
update-kbd () {
permissions
sudo tee "$kbd" <<< "$new"
exit 0
#<- Run Contents ->
case "$1" in
-h|--help)
usage
increase)
current="$(<"$kbd")"
new="$(( current + kstep ))"
update-kbd
decrease)
current="$(<"$kbd")"
new="$(( current - kstep ))"
update-kbd
usage
esac
Assuming you have the correct file being pointed to, you should be able to just run (assuming you keep it named "enlighten")
# ./enlighten increase
Let me know how that works for you.
All the best,
-HG
Ok so i copied that script, and tried to run "./enlighten increase" but it said i needed to be sudo, so i did it with sudo, and it said "sudo: ./enlighten: command not found"
Then i just did 'sh enlighten increase" And this time it gave me:
enlighten: line 29: `update-kbd': not a valid identifier
I have no idea what that would mean.
When i google "`update-kbd': not a valid identifier" all it comes up with is my topic lmfao. Not much help there.

Blue light on I-trigue 3400 does not light up

Blue light on my I-trigue 3400z does not light up... any reasons for this error, the system is less than a month old...

Only reason, the speaker is faulty. The problem either lies with the power adaptor, subwoofer or volume control. Nothing much you can do now, contact their customer support or best get it exchange with the store.

HT1459 Just bought a new ipod shuffle for my kid and cannot set it up because it does not show up in itunes. Also the charging light does not light up. what could be wrong, as i am able to see both my iphone and ipad on itunes on the same pc?

Just bought a new 4th gen iPod Shuffle for my kid. Problem is I cannot do the initial set up, as the device does not show up on iTunes on my PC. Also the charging does not light up. Any ideas on what could be wrong, as I am able to see both my iphone and iPad on iTunes using the same PC?

I also tried manually underlining a few things on the new iPad and when highlighting a paragraph, it would skip a few lines and the line would go through a few as well. Looks like a major iBooks glitch needs to be addressed here.

New 13" Macbook Pro trying to connect to a Panasonic VIERA TC-L42U30 as second monitor. I've used multiple hdmi-thunderbolt/mini displayport adapters and multiple hdmi cables and still no success. The Macbook does not sense the second monitor (TV). Help?!

I've been a Mac since 2008, so I know my way around the system pretty well. This issue, however, has me stumped. I had an iMac until now and only now am I experiencing some difficulty with my new MacBook Pro. The model I have is the newest 13" Macbook Pro model and I'm trying to connect a Panasonic VIERA TC-L42U30 42" HDTV as a second monitor via the Thunderbolt port.
It worked the first two times and hasn't worked since, after 10-15 attempts with different configurations, turning things on n off, restarting the mac, unplugging the cables, adapters, TV, resetting the P RAM, etc... I've used multiple hdmi-thunderbolt/mini displayport adapters and multiple hdmi cables and still no success. No matter what I do, the Macbook does not sense the TV as a second monitor anymore.
I took the MacBook Pro to the Apple Store, and their "genius" there had it working fine with a DVI connection to a regular monitor. The Panasonic TV I have has HDMI connections and one VGA connection which does not support HD, but no DVI option. I want an HD connection to mirror or extend my MacBook Pro screen. At the Apple Store, they didn't have a Thunderbolt/Mini DisplayPort to HDMI adapter, so he could not try that out for me.
Anyone else have this configuration or another similar one with a Panasonic HDTV?
Ideas? Suggestions? Anything?! Help!!
P.S. I'm running Mountain Lion, if that wasn't already obvious. Everything is up to date in my App Store as well.
Thanks!

Hi There,
I have had the exact same issue but with a projector.
The issue lies with Mountian Lion 10.8.2.
I tried many a combination with no luck to get HDMI working.
Took my mac into the apple store and came to the conclusion it was the software, so I asked them to install 10.8 onto it (this is destructive so a backup is a must)
Bought my macbook home and voila, now displaying through my projector.
There is a small graphics update after 10.8.1 which seems to be the cause.
Hope this helps.
Thanks.

HT1338 I am still with 10.5.8 and my macbook does not show any software updates, i am willing to pay for a new software if it is needed, because i can't connect mi iPhone 5S or iPad mini to iTunes. PLEASE HELP!!!!!

How do i update 10.5.8 if my macbook does not show any software updates?

Upgrading to Snow Leopard
You can purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard - Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mountain Lion if your computer meets the requirements.
     Snow Leopard General Requirements
       1. Mac computer with an Intel processor
       2. 1GB of memory
       3. 5GB of available disk space
       4. DVD drive for installation
       5. Some features require a compatible Internet service provider;
           fees may apply.
       6. Some features require Apple’s iCloud services; fees and
           terms apply.
Upgrading from Snow Leopard to Lion or Mountain Lion to Mavericks
To upgrade to Mavericks you must have Snow Leopard 10.6.8, Lion, or Mountain Lion installed. Purchase and download Mavericks (Free) from the App Store. Sign in using your Apple ID. The file is quite large, over 5 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
     OS X Mavericks- System Requirements
       Macs that can be upgraded to OS X Mavericks
         1. iMac (Mid 2007 or newer) — Model Identifier 7,1 or later
         2. MacBook (Late 2008 Aluminum, or Early 2009 or newer) —
             Model Identifier 5,1 or later
         3. MacBook Pro (Mid/Late 2007 or newer) — Model Identifier 3,1 or later
         4. MacBook Air (Late 2008 or newer) — Model Identifier 2,1 or later
         5. Mac mini (Early 2009 or newer) — Model Identifier 3,1 or later
         6. Mac Pro (Early 2008 or newer) — Model Identifier 3,1 or later
         7. Xserve (Early 2009) — Model Identifier 3,1 or later
To find the model identifier open System Profiler in the Utilities folder. It's displayed in the panel on the right.
Are my applications compatible?
         See App Compatibility Table — RoaringApps.
Upgrading to Lion
If your computer does not meet the requirements to install Mavericks, it may still meet the requirements to install Lion.
You can purchase Lion by contacting Customer Service: Contacting Apple for support and service - this includes international calling numbers. The cost is $19.99 (as it was before) plus tax. It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
     Lion System Requirements
       1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,
           or Xeon processor
       2. 2GB of memory
       3. OS X v10.6.6 or later (v10.6.8 recommended)
       4. 7GB of available space
       5. Some features require an Apple ID; terms apply.

When i connect my ipod nano to my computer it does not light up and i get a message saying the usb devive has malfunctioned

I need some help here as I believe my ipod nano has crashed or something is terribly wrong. When I plug in the usb to my laptop I get a message saying the usb device has malfunctioned. My ipod does not light up. I have tried powering it on manually and nothing works. Help, this is going to ruin my workouts!!!

I'm not sure what the glitch was, but after I posted the problem, I called Apple and got a rep to walk me through some troubleshooting tips such as holding down the nano power button while plugging in the usb cable....nothing worked. Eventually, they scheduled a maintenance /replacement service.
I got the box yesterday and was about to put it in for shipping to Apple, when I decided to try connecting it to my laptop one last time. Viola! it started back up again and is currenting syncing as I type. Guess it was just a bad glitch of some sort. Anyone with a similar issue, perhaps you may want to wait a few days and see if it solves the issue.I hope this helps.

New macbook does not "see" my network, old macbook pro and iphones do...

Yesterday I installed an upgrade to my airport extreme base station, now my macbook pro and the 2 iphones in the household see the wifi network but the other macbook does not. It does see the neighbors wifi networks and will see it when I connect via a cable to the base station by no wireless connection... help!

I am having a similar problem. I have 19 iBooks in a classroom and, suddenly, none of them can see the AirPort Express network when they log on. Instead, the iBooks try to connect to a Windows-based school network. I have designated the AEBS network as the only preferred network but the iBooks NEVER try to connect to it first. However, if you click on the AirPort icon in the menu bar, the AEBS network is clearly visible and clicking on it immediately connects you to the AEBS network.
When I originally set up the network in January, everything worked just fine. After the upgrade to AE Firmware 5.7 and various OS X 10.4.5 updates, everything has gone downhill. I had the dropped signal problem that so many have reported. I downgraded to AE Firmware 5.5.1 and followed J. Exby's procedure to upgrade the AEBS framework. That solved the dropped signal problem. But now my iBooks cannot find the AEBS network when they log in.
I have set the AirPort Network Preferences to connect Automatically or to Preferred Networks with the same result. I have also set the option to "Keep looking for recent networks" and it never finds our AEBS network. Yet, the network can be accessed manually through the AirPort icon.
BTW, I use one of the iBooks myself and it works perfectly and finds my preferred network in 2 other locations with non-AEBS networks. But it cannot see its own preferred network in school.
This is really bugging my students--and me! Any suggestions? THANKS!

MacBook does not go to sleep lid is closed

My new MacBook does not go to sleep when I close the lid. I have to manually tell it to sleep before closing the lid.

I'm having the same problem too. I only noticed it recently!
I have Parallels VM installed, but not BootCamp, but just incase I restarted the Mac then with nothing running tried closing the lid but MacBook stays on. I've checked the Energy Saver settings, usual put computer to sleep after 1.5 hrs and put the display to sleep after 15 mins, but that shouldn't make any difference when I close the lid.
I don't have an external monitor, and i unplugged by USB mouse too.
Another thing I noticed yesterday is that even after leaving the MacBook idle for 1 hour, my screen had not dimmed, and Skype had not gone to 'Away' even though it is set to goto 'Away' after 5 mins. It's as if there was something using the computer? I dunno!
And Ideas?
And if I DO tell it to goto sleep before I close the lid, when open it again, I need to hit 'anykey' wake it!
