I can't wake up my MacBook without power cord since firmware update

Even though my battery charges fine and it's on 99% full
it won't wake up without a power cord.
when I walk away from the computer and close the lid, when I open it again and hit the space bar nothing happens. I have to hit the power up button and still nothing happens. then I plug in the cord and I get the grayed out screen and see the energy coming back with the white stripes loading across the screen.
Now I just pulled out the cord with it on and sat there for 1 minute to see what happened. The computer shut down! My MacBook effectively can't get the energy off my battery. What is going on??
This just started 2 days ago right after it asked me to load new firmware. I don't even know why I needed to update the firm ware but all I know now is my Macbook can't live without the power cord now and I was fine before. HOW DO I UNINSTALL that FIRMWARE UPDATE?? or HOW do I fix this??
please help me

My macbook is presenting the same problem after firmware update. Resetting the smc didn't work, as well as resetting the pram and repairing permissions in safe boot mode. Help, please... my mac suddently turned to be a PC.... simply not working!!!!
I tried to clean the battery plate, as well, but i am able to wake my mac up only with power cord plugged in... after restarting the computer, by pressing the power key for 10 seconds, the battery works pretty good...

Can't stop Thunderbolt display from flickering white lines after firmware update (Yosemite)

I am having serious issues after the Thunderbolt Display Firmware Update 1.2. Running Yosemite on MacBook Pro and I am now getting white lines that gradiate from the bottom to the top of my screen across multiple browsers, apps and even the finder window anytime I move my mouse. I cannot take a screenshot (it stops when I try) but I posted a video here:
http://youtu.be/3zOKL1JFp5M
It is impossible to work this way and after 20 minutes of watching my screen constantly refresh anytime I move my mouse I am feeling nauseous.
Is there anyway to UNINSTALL this firmware update? I was not having this kind of problem before. Every once in awhile I was finding my Thunderbolt display would not wake up after sleep and I thought the firmware update would fix that, not cause more, crazier problems. It is causing this gradiating line problem on my Thunderbolt display AND my MacBook Pro screen, which is even more bizarre.

I updated and no issues with my 2012 Mini so may be computer related. I believe once a firmware has been "burned" into the chip it cannot be redone.

My macbook air power cord glows orange vrs green what needs fixed?

my macbook air power cord glows orange vrs green what needs fixed? the battery is not charging now, but the power connector glows green briefly and then goes to a steady orange. is this a power cord issue, a battery issue?

The orange LED indicates that the battery is in the process of being charged. Depending upon how depleted the battery is, it might take 4 hours to completely recharge.

How can I start up my macbook without using the power button ?

Hi guys,
I think my macbook's keyboard/trackpad/power have died. I was wondering if there's anyway to start up my macbook without the power button, I was thinking about an external keyboard that would hae a power button on it, I don't know ...
I have not used my Macbook for the past 4 days and i think it's making me sick ...
Thanks !

hey,
So i bought a G3 keyboard with the power button and i just received it but my macbook still doesn't want to start up.
It's pretty strange because my macbook was still running when the top case died and I had to unplug it cause i couldn't shut it down so I was sure that buying this keyboard would make it work but it doesn't. I am wondering if it could be from the power button that would be died cause when i push it, it doesn't feel like the one on my macbook . It's pretty hard to explain but could someone tell my how it supposed to be when i push the power button . On my keyboard it just goes down and goes up without doing anything...
I'm pretty sad cause I haven't used my macbook for weeks and i'm started thinking it will never start up again ...
Thanks

MacBook shuts off without power cord, even when battery is charged

I bought my MacBook in October. I've been treating it really delicately. But for some reason, it will not run without the power cord plugged in (as of yesterday morning).
If I pull it out, it shuts down. If I try to start it up without the cord, it shuts down. It gets about 2-3 seconds before it just shuts off. (It will run in sleep mode without the cord plugged in.)
And for a brief time yesterday evening, it worked without the cord plugged in.
This is my first Mac and I have no idea what is going on.

This is a recently common issue with Macbook Lith-ion batteries.
You have a defective battery, although AppleTech defines defective as a battery below 350 cycle counts. That's the lifetime of your $130 battery, which may average between 6-13 months depending on how you use it.
Some customers have had to buy 3 batteries in the past 2 years because AppleCare doesn't cover consumable items, eg. batteries.
check consumer comments at http://store.apple.com/1-800-MY-APPLE/WebObjects/AppleStore.woa/wa/RSLID?fnode=h ome/shopmac/macaccessories/power&revw=MA561LL/A
I'm hoping Apple will realize that a $130 macbook battery with a 350 cycle count lifetime, doesn't live up to "Apple" standards. Lith-ion batteries are known to have a 2-3 year lifetime not 6-13 months.
Customers shouldn't have to purchase AppleCare only to realize they have to continuously purchase new batteries every 6-13 months.
This is truly a manufacturer defect in my personal opinion.

Battery on MacBook doesn't work after Firmware Update

Hi - I updated my MacBook with the Firmware Update as soon as it popped up on the screen. My MB has been exhibiting the random shutdown problem. Everything worked fine until I restarted my computer, and now it will not operate without the AC adapter plugged in. If the power cord gets disconnected, the computer shuts down immediately. It is no longer portable. I've repaired permissions, which (of course) didn't fix the problem. Any ideas?

thats good news then in my case if its the logic board. The cpu whine has been driving me nuts(being excessively louder then most other macbooks with the whine) so I've been wanting to get the logic board replaced anyways.
Dont worry about the applecare though since we all should have it within the 1 year warenty still so all repairs should be covered.
Imo I'm considering purchasing the extended applecare protection plan if i can come up with the money( $249 is a bit steep for me) to get anouther 3 years of warrenty service expecialy with all the problems macbooks have been having.

MacBook Pro boot failure after firmware update

Hello,
I've had my MacBook Pro with a solid state harddrive about a month. Tonight I did an update (including a firmware update) and it has failed to boot. The fans run at full speed, but nothing boots. The screen remains blank. What can I do?

iTunes sound works - but no internet sound!!

Macbook pro power cord frayed and not charging

Ive just noticed I have the same power cord problem. I plugged in the cord into my macbook and noticed that the light did not turn on. Upon closer inspection I noticed the wire was frayed and was real hot. I have not moved my power adapter or have had something happen for it to be that bad. Im not sure if Im still under my 1 year warranty plan thing, but I was wondering if I took it into the apple store they would still replace it. So if anyone has been in this situation and knows the best option, besides spending the 80 bucks for a new one I would greatly appreciate it.

Hope you feel better.
I assume the OP bought it there and can certainly go back under the 1 year and show them another melted one as there have been enough melted ones for them to know this is a bit of a problem. He can call Applecare as well of course.

Macbook PRO EFI 2.3 firmware update broken

EFI 2.3 firmware update broke the network again. EFI 2.2 fixed what was broken in 2.0 & 2.1 but the
same problem is back in 2.3. Laptop wakes up and I have to wait about a minute for things to kick-in.
I am able to use utilities using system calls (ping, dig, etc) but Mail.app, Safari or anything else for
that matter is reporting that network is down (not sure if these are using an internal caching daemon
or something similar). On the initial 2.3 update the screen wake-up was also broken, I would touch
the pad or a key but the screen would remain dim and would light up after 30 or so seconds. Applying
2.3 twice fixed this issue. Following is an entry from system.log, you can see that the laptop is trying
to connect to the AP twice:

At one point I though it was Parallels that's breaking this, but disable/restart of Parallels did not help.
Any hits ?

Wow! Exact same issues here. Exactly! The same slow screen-wakeup and screen-saver freezes.
Additionally, any time I try to view video in a web browser, it freezes (other things seems to do it too, but the web video (e.g. youtube) was one thing which was a reliable/reproducible cause of crash). BUT, when I use gfxcardstatus to force Discrete graphics only, then it seems to work fine. Manually switching it to Integrated (with gfxcardstatus), or allowing it to automatically switch, results in an immediate freeze. The freeze is not a kernel panic; the mouse still moves, but the interface is totally unresponsive. Well, technically almost totally unresponsive: Ctrl-Eject did EVENTUALLY (like, after minutes!) bring up the shutdown dialog on at least one occasion. But that's largely irrelevant, I can't work like that.
I had real trouble trying to install the EFI 2.3 update - in fact, I have not managed to install it according to Software Update.
After "installing" EFI 2.3, upon restart I get a bad chime (the sad-Mac sort of noise) rather than the usual start-up chime. Then there's a noise as though it's trying to spin up a hard disk or something, which abruptly cuts off though. It does that a few times (brmmmm,chk...brmmmm, chk, ...). I force-restarted it with the power button, held Cmd-Opt-P-R and then it did it's usual restart, and then booted. But Software Update says that the EFI 2.3 firmware is not installed.
Sounds like a hardware issue to me. Any thoughts?

Early 2011 Macbook external display issues after firmware update

I have a 2011 MBPro 15". After performing the firmware update in late April, I have continual issues when I connect my monitor. The screen is blank and I can move the mouse tap the keyboard etc. The display may come up for a scond and then it will close and the machine goes back to sleep. More wiggling and the process starts over.
If I raise the lid it may bing up the external display. Restarting is the only sure fix.
I also was unable to make a presentation today because the projector I was connected to would not show the MBP display.
I tried all the key combinations, detect display etc. and nothing.
Can I somehow go back to the prior firmware? Other solutions?
SMC Version (system): 1.69f1
EFI Driver Version: 01.00.521

I recently did a software update to my MacBook pro and had a similar issue, on restart it gets to the apple logo then just shuts off, after multiple hours on the phone with apple care they told me that it was coincidence that it happened at the same time as the update and it would be costly to repair as it was either something to do with display or logic board. I took my MacBook into my retail location I bought it from and was told that they have had MULTIPLE people bring in macbooks with the SAME issue (I live in a really small city so the amount of people is quite large proportion wise) and that they could fix the issue by remotely resetting the MacBook at a cost of $130-$150. Relatively cheap considering what I was fearing, but if this is a common problem related to Apples update why are we paying to fix it and why is apple support saying its something major???

HT1237 MacBook Pro model: MacBookPro5,4 firmware update

I looked up the system report for my MacBook Pro and is listed: MacBookPro5,4. I am not seeing that model listed for firmware updates. How do I find the firmware update for my model?

Try downloading the Mac OS X 10.6.8 Update Combo. First do this:
Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. 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 click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
Now reinstall with the combo updater.

MacBook Battery Shutdown issue after firmware update - anyone reinstalled?

Has anyone tried re-loading their OS? I have this issue too (though my battery lasts about 30 minutes) and this it powers down. I called apple (my SN starts with 8609) and told them I had a battery issue.
They were not much help - they indicated to me that I am over my 90 days for phone support and that I would have to bring my battery in to the store to have it tested. They went further to say if it is a firmware issue and not a battery that is technically software and I would be charged $50 for battery testing if it passed. And that if there was actually a battery issue they would replace under the 1 year hardware warrenty.
My dilemma now is should I try and wipe/reinstall the base OS (which I was told will undo the firmware upgrade).
I thought I would check here to see if anyone tried this before swapping battery???
I seems that the firmware update caused the problem but I am not sure if the battery is still good and the firmware is just crap or if the battery might still be ok. Has anyone wiped/re-installed the os and fixed this issue?

thats good news then in my case if its the logic board. The cpu whine has been driving me nuts(being excessively louder then most other macbooks with the whine) so I've been wanting to get the logic board replaced anyways.

One Macbook, two power cords?

The two-pronged power cord fits the "magnetic" part of the cable nicely. It sparks with wall connections, though.
But my new Macbook also came with another cable; it has a three-way "male" connection on one end, with what looks like a small, tubular barrel on the other. How exactly does this second cable fit? Do I still use my "magnetic" cable? Why bother having a thick, three-way cable when my two-way "magnetic" one is thinner and smaller?
I can't figure how the second cable would fit anything. I've not yet seen any pictures.
Thanks!

The extension adapter has two purposes. It gives you more reach when you aren't close enough to a wall outlet using the two prong adapter. It also gives you a good ground that you don't have with the two prong adapter.

HP printers without power cords!

Hello,
Why HP's printers have been shipped without a power cords in some countries? Is it because HP aims to deliver it quickly and making the power cords would delay the delivery process?
Thanks in advanced

Hi,
Very good question. In my country, the laws protect comsumers and every electical machine MUST have a right power cord. Probably it's bit relax in your country and they (could me many vendors) can get away with that.
Regards.
