2 monitors, laptop closed, power adapter removed = sleep

I have a Macbook Pro Retina 15 "
It is running Mavericks 10.9.2
I have the following setup working:
- 2 dell monitors plugged in via 2 thunderbolt ports
- The macbook lid closed
- The power adapter connected
The problem arises, when I unplug the poweradapter; When I do so, the laptop goes to sleep.
I would like to be able to unplug the power adapter, so I can treat the laptop battery better and extend its lifespane and quality.
How do I achieve that?
Thanks,
Brad

Mid-2009 13" MBP says "not charging" but seems to be slowly charging with power adapter

I have a mid-2009 13" Macbook Pro with 8GB RAM. I have the odd situation of the power indicator on top right of screen showing that the power adapter is plugged in, but the percentage indicator stating that the laptop is "not charging." I have been working on the computer for several hours and the laptop has only charged to about 27 percent according to the battery health application that is runningI have. It says the battery has gone through 281 cycles and is 2.4 years old. It suggests the battery should still charge to 92 percent of its potential. The battery is warm as is the power adapter cube, so something is happening. The little light on the end of the power cord is green but only two of the little green dots light up on the left edge of the computer.
Any ideas if this is a battery, laptop, or power adapter problem? Unfortunately, I don't have a second power adapter to test that idea. Thanks for any suggestions.

Recalling another similar thread, I can recommend you thoroughly clean the male and female MagSafe connectors. The gold pins and pads must be shiny bright and totally debris free. Use a Q-Tip moistened with alcohol, disconnect the power brick beforehand. Also, make sure the rubberized area around the connector in the Mac, where the magnet lies and the steel ring around the cable connector nestles, is completely free of anything that can prevent the two from fully mating and ensuring a tight grip.

Problem with Power Adapter. Please Help!

So, I recently noticed that when I try to use my laptop while it's charging up from a low battery it will randomly STOP charging. The annoying phenomenon usually occurs when I play video or surf online as the computer recharges from a low percentage (5%-50%). Now, I should be able to use my computer while it's charging, right?? Also, I discovered that the power adapter gets hot and makes a humming sound that grows louder right before it shuts off. The odd thing is, is that the laptop will charge just fine if I leave it alone. Weird!
I wouldn't be all worked up about this, but here is what has happened so far:
I have taken the laptop and power adapter to Apple several times and explained that the orange LED light shuts off and that I have to plug the adapter back into the wall to get it to come back on.
So far, the people at Apple have:
1) replaced the first power adapter (that did not work, so I went back)
2) gave me another power adapter (that also did not fix the problem)
3) actually replaced the battery (also did not solve this problem)
I don't know what to do because I don't want to look petty over a stupid problem. However, I have the warranty and this problem is becoming VERY annoying.
Any ideas or similar situations?
Thanks,
Aaron

Hi. Have you tried resetting the SMC: http://support.apple.com/kb/ht3964

Stop the sleep blinking light in lenovo g-470, whining sound from the power adapter , HEEEEEELP !!!

Hi, hope anyone can help me.
I own a lenovo b560 and a g470, the sleep light will blink when I go to sleeping mode, anyway the problem is not the light, the problem is the whining sound it produces the power adapter when the light start blinking, in both machines I hear that whining noise, but in the g470 is much louder, I don´t know if this is because I have a faulty adapter or something, the strange thing is that both adapters make the noise when I sleep the laptop, when I turn off or hibernate the whining sound disappear.
Also, I notice that the whining sound alternate in 2 types of sounds, one is high in pitch and the other lower, the high pitch is when the blinking light turn on when go to sleep and the lower pitch of the sound is when the light go off, and that is repeating until I resume the laptop, it´s very annoying, especially when I´m in a quiet room.
So my theory is that maybe somehow I can turn off the blinking light when the laptop goes to sleep and then maybe the whining sound will go away, but I don´t know, it´s only an a idea.
Any help will be appreciated.
Thanks !
Solved!

I can really understand your pain with this issue.
Kindly update the BIOS and display driver from the lenovo website then check if the issue persist.
The issue should be resolved after this.

Hp zv5242qv laptop with windows vista will not run on battery but will run on power adapter

Hello, I have a HP zv5242qv pavilion zv5000 series laptop with windows vista installed. I can run it on the power adapter with and without the battery installed but it will not power up on just the battery, the battery is new and fully charged. When I plug in the power adapter the battery light on the front of the laptop comes o then goes off, anyone have any ideas about my problem ?

Hello,
The situation you describe looks like the unit has problems with the battery, but you say the battery is new and is fully charged.
Then, the issue might be with the system board and maybe there isn't anyhting you can do.
You can try to remove the battery and the ac adapter, and keep the power button pressed for 30 seconds, then connect the ac adapter, turn on the unit, then when in windows put the battery in place, see how it is detected, the power level and restart the PC. See if the unit restarts with the battery in place, if yes, then shutdown the unit.
See what happens and report back.
Thanks,

Spilled Drink - Laptop won't recognise power adapter + screen backlight

Hi.
The other day, I had my 17" MacBookPro in a satchel bag, but made the foolish choice of leaving my Lucozade (Orange flavour if that helps!) in the bag.
Obviously, the Lucozade burst, submerging around two inches of the laptop, there part where the screen connects to the laptop, and submerging the power adapter port.
Now for around twenty four hours, the power adapter charged the laptop, but unfortunatly, the backlight on the screen suddenly didn't work, as in you could very faintly see it, but when you try to turn the display up, nothing happened.
Twenty four hours after the spill, the power adapter failed. I'm pretty certain it isn't the power adapter, which means the problems seems to lie with the power adapter port.
Now I opened up the laptop two days ago, (three days after the accident), and cleaned what ever Lucozade there was, and just in general cleaned up the insides of the MacBookPro (which is now around two-and-a-half years old.) Unfortunatly it didn't work.
So currently I have a MacBookPro with no battery power, and no screen backlight. So what i'm asking is for any advice at all!
Is it worth taking it to an independant laptop repair business? Would they be able to do much more than me?
Should I take it to a Mac shop? Would they know what to do?
Is there anything I can do myself?
Anyone else had a similar experience?!
Thanks a lot.
Christian.

I think the problem may be with the inverter board or cable. Do you have access to an external display? Maybe one you could borrow? If so, hook it up and see if you have good video on it. If you do, that would indicate that the video chip on the logic board is OK. And if you can get good video on the external, it would be a good opportunity to run the Apple Hardware Test.
One thing is that you really need to remove all traces of the Lucozade or you could have further issues on down the line. You could practice on the I/O board you removed. Flush it thoroughly with distilled or deionized water and dry it thoroughly (this could take weeks, maybe less if you have a warm dry place for drying). You could try cleaning any affected part this way, and it's possible--though not certain--that it could work again.
You probably have found ifixit and PowerBook Medic by now. Let me give you another link:
http://node123.cit.geneseo.edu/~stratton/ServiceManuals/
This is an index--you will have to find your specific manual and download it. But I think you'll find it useful.
Good luck!

MacBook won't start on battery/shuts down when power adapter is removed

Help & advice needed please.
My MacBook won't start without external power, it gives a whir then a click then nothing. Once started up, if I remove the external power it just shuts off.
The battery shows at 98% & charging. Coconut Battery shows the following:
Current battery charge 4126 (& increasing as I type)
Maximum battery charge 4200
Current battery capacity 4200
Original battery capacity 5200
80%
Battery loadcycles 111
Age of your Mac 6 months
Charger connected yes
Battery is charging yes
Does anyone have a clue why the Mac won't power itself on the battery when everything else seems like it works?
Cheers!

As of today, my MacBook and I have been together for 40 days. Yesterday, while I was happily surfing (on battery), it powered down with no warning. Okay, these things happen. I plugged it in, restarted, and all seemed to be fine. Battery was about 70%. I did other things on my other machines and when it was about 90%, unplugged it and everything was good. This morning after using it unplugged for 1.5 hours it did the same thing, but decided to only work with the power adapter, not on battery alone. When trying to boot without AC, it would try to spin the CD and then fall back into off. When on AC, if I pulled the adapter, it would last two seconds and go blank. I made an appt. with the Apple store (Fashion Show Mall, Las Vegas) for 3:20pm. I got there right at 3:20pm and the monitors showed I was 5th in line. Store was fairly packed, at least one patron at every display item. Monitors also said the next MacGenius appt. was "approx. 8:30pm." Glad I made an appt! I was served about 15 min. later, during which time the monitors had changed to "No more MacGenius appts. available today, please try tomorrow." However, one guy came by without an appt. and was told he would be put on standby and to come back in 30 min.
Once I explained my issue with my MacBook battery, my Genius tried one of his batteries. "I just want to make sure it's your battery and not your motherboard." My machine worked fine, so he said "No problem, I'll have you out of here in 10 minutes." He got me a brand new battery, tested it, and put my old one in a box on the rear counter with four others. He pulled the serial number from the "About this Mac" area, didn't need my receipt for purchase date or anything. I had even printed this page: http://www.apple.com/support/macbook_macbookpro/batteryupdate/ to use as ammunition, but didn't need it. He did approve highly of my dashboard widget "iStat pro", available here: http://islayer.com/.
So the battery issue is a very common problem, and one that Apple has tried to deal with as painlessly as possible for the consumer. My Genius did ask if the battery showed an "X" in the icon bar, and I said no. Just wouldn't run on battery. On the way out of the store, one of the 3 MacBooks, in fact the one closest to the door, had an "X" on the battery icon. When I unplugged the power, it shut down immediately! The moral of the story is to contact Apple immediately with problems and give them a chance to fix them. Hope this helps others.

Sleep and the Power Adapter...

I have been having iBook sleep problems and here is an example. working on ibook with power adapter in. i close the lid and it goes to sleep but wakes up and goes back to sleep then finally its asleep. ok i click on my mouse and it wakes up. another would be i manually go and click on the sleep option and while the lid is open it sleeps wakes sleeps wakes...finally sleeps. i close the lid click the mouse it wakes up... so i decided to reset the PMU and everything and did the same test and the same things happend. then for some reason i said let me try this with the power adapter unplugged. so i tried it and now the sleep function is perfect. i put it to sleep without the adapter and i press on the mouse and it stays asleep untilll i open it...weird but does anyone know what i could do to fix this when its plugged in? anyone else have this problem? thank you.
iBook G4 14 inch. & Imac G4 15 Inch Mac OS X (10.4.1)

Hello Steven,
I think the reason this is happening is just because of the mouse that is connected to the ibook. I have an external mouse that I connect to mine. When the ibook is connected to the power adapter, it will wake up if the mouse is clicked, because it is getting a signal, and therefore wakes up, then goes back to sleep (when closed) because of the switch inside the computer telling it to sleep. This also happens if you connect something to a USB port. I don't know exactly why this doesn't happen when it is not connected to the power adapter (Maybe to conserve battery power?), all I know is that it just doesn't happen.

Laptop won't turn on - the power adapter light flashes three times? G62 b29SA

I've been replacing the fan in my friend's laptop. I had a problem with the trackpad not working after I put it back together and that problem is not yet resolved but I have another problem preventing me from getting further. Now when I press the on button, the power adapter light (next to the socket for the external power) flashes three times and that's all. It flashes again three times every time I press the power button. It does this even with an external power source plugged in (I'm pretty sure that it's supposed to just stay on constantly when the charger is plugged in but the power source I have is a universal one set to 19 V - it has powered up with this plugged in before but I don't know whether it was taking charge from it). Any advice?
This question was solved.
View Solution.

I got the charger from my friend and now it boots up just fine. There seem to be many meanings to the three flashes based on my Internet searches but in this case it appears that it's some way of indicating a low battery.

"Universal Laptop DC car charger power adapter" for Lenovo g530

Hey there, I'm a complete tech numskull, so pardon me if this is incredibly naive. I recently made an impulse buy of an off-brand "Universal Laptop DC car charger power adapter" with the hopes of using it in a car with my Lenovo G530. I haven't gotten it yet but after purchasing it, I noticed the power adapter that came with my Lenovo is "AC." Is it possible to us the DC adapter with my laptop, where my cord says "AC"? I obviously don't want to fry my laptop and was wondering what I should look out for. The adapter was pretty cheap, which is another red flag but it also means I won't be out much if I made a mistake in buying it (ebay purchase).
Thanks in advance for your input.

It seems the spare is the new specs. Check these 2 spares. They are the same 4.74amp. http://www.amazon.com/Lenovo-3000-G530-444638U-Adapter/dp/B002Z209G6/ref=sr_1_3?ie=UTF8&s=electronic... http://www.amazon.com/COMPUTER-Power-Adapter-Cord-LENOVO/dp/B002MY2MLM/ref=sr_1_1?ie=UTF8&s=electron...

T60 - Lenovo 2623 laptop and Aluatek STD-19034 Universal Power Adapter

I have a T60 - Lenovo 2623 laptop with a standard power adapter that I got in an office lottery. It is a great system. I wanted to get a second power adapter to have in my day bag for the just-in-case situations and found an Aluatek STD-19034 Universal Power Adapter at Fry's Electronics. The device and their website state that they are compatable with the Lenovo laptops.
Part Model: STD-19034
Brand: AC Adapter - Original Aluratek Part.
Description: Aluratek STD-19034 AC Adapter open end :: Input: 100-250V 47-63Hz 1.4A
Output:19V 3.4A
http://www.adaptertech.com.tw/JP/16_ac_dc_switching_adapter.html?CID=2
Since this is a 65w adapter, my question is will the device really be compatible with my laptop. The standard Lenovo adapters for this laptop are either 60w or 90w. The Amp output on the Aluatek is between the two standards, but the Voltage output is 19 versus the standard 20. I don't want to damage my laptop.
What do you think ? safe to use ?

NOTE: Reviews may require prior approval before they will be displayed

Lenovo uses 20 V adapters, so from that perspective this is already looking bad. Also, there is different plug sizes and polarity, so you have to make sure this matches that with your normal adapters.
I would suggest you stick with the OEM laptop adapters.

Does a usb cab to 60 Watt L-Tip Power Adapter charger for Apple MacBook Pro Laptop Charger exist

does a usb cable
does a Usb cable to60 Watt L-Tip Power Adapter charger for Apple MacBook Pro Laptop Charger exist? i have an external battery pack i would like to use to charge my iphone and macbook pro.

Not that I am aware of. An Internet search on your part will be required. If you should find something to that effect, note it will not be endorsed by Apple and the magnetic connector will probably be in violation of Apple patents.
Ciao.

Any risk of using a 16v 4.74A power adapter for a laptop where it is indicated 15v 5A

Do i have to use power adapter to charge laptop?

We have an 11-inch MacBook Air (mid-2012) which came at the time with a power cord permanently (apparently) attached to a heavy (annoying) power adapter, which then becomes the 5 pin plug to charge the laptop. Is there a way to charge this without this bulky cumbersome long plug & heavy adapter? The small space where we use this & taking it anywhere makes this extremely annoying. Any help is appreciated.
Thanks!

Thanks Csound1… So this cannot be changed via USB or some other way the 5 pin plug can plug into some other lighter wall adapter? It just seems strangely cumbersome. The adapter looks like you could pull it apart or unplug it from itself. The ones I see online for sale (see attached photo) look like this. Mine has the same skinny wire attached to it (other end is the 5 pin magnetic plug to Air), but the other side of my adapter (in this picture where this looks like it would open), I have another thick wire which seems permanently stuck to this adapter and the end of that long thick wire is what plugs into the wall. Mine has this same "look" where you see the lines that imply it would open or be a plug of some sort, but this is where my thick electric wire is attached. Is that permanent or can I pull it apart and there's really a plug there to plug that into the wall (the adapter itself I mean). Hope I'm making myself clear.
Thanks!

Is the power adapter rated 100-240v for the HP Stream 13 Laptop ?

Hi,
I want to buy it. and i want to be shore about the voltage...
.....Is the power adapter rated 100-240v for the HP Stream 13 Laptop ?
Thank You.

I might have tested it myself a few months ago, I cannot remember the results but I believe booting from the SD slot is not supported by the UEFI firmware. It is mentioned here in the comments of this Amazon review for the Stream 11: "I have not been able to boot ANYTHING from the micro-SDXC slot. I can install Ubuntu on it, but I cannot boot from it. I don't know if booting is even possible."
