My MacBook Pro retina does not work on battery backup?
Cannot run if I plugged the AC adapter, if I check battery heath it shows 29% charged and its normal state.
Try a SMC reset:

If there is no change, bring the product service.

Macbook Pro retina does not illuminate
Hi all
I have a 2015 13 "Macbook Pro, that will not start at all. Last night I came back after a day holiday and powered to the top of my Macbook for the first time in two weeks. The battery level was around 25%, so I plugged the magsafe and did some navigation / watching Youtube. I noticed the GET a little slow mac and a youtube video stutter a bit, but it was late so I was not too concerned and put the Mac to sleep mode by closing the lid.
This morning, after waking up, I noticed that the magsafe light was still orange, which seemed strange to me as he did pay for one night for a good 10 hours. I opened the cover, but the mac does not wake up. I pressed the power button and the computer booted. At first, everything seemed OK but the computer seems slow and internet soon.
As the bright light battery was still orange that I flew over the battery icon, which showed 100%. I unplugged the magsafe and he fell immediately to 0%, so I reconnected it. I went to make a diagnosis, however about 20-30 seconds later the computer shuts down.
Since then, he failed to power to the top of all and nothing I have try works. I tried to hold the power button down, but nothing. There is no edge and the caps lock button is not illuminated, so I know that is not a problem of display.
I left the magsafe plugged in for 4 hours, and it's still orange.
I have reset the SMC. While this life Magsafe turns green for a few seconds, and then turn the orange back.
I tried an another magsafe, which is the same, so I've reduced that as a problem.
I spoke to Apple support, who say it could be the battery and take it to an Apple store. My most close is a 150 miles round trip, and there is no reserves for the next 8 days. I'm sure this will be a hardware problem, but everyone does not accept that it is likely to be the battery? I did have problems with the battery before it and the charge went really well. Would not the Mac boot always if there was a problem with the battery while it is still plugged into the mains?
Any help or insight is greatly appreciated
There could be several reasons why your macbook pro turns on. Just throw the grounds up into the air and choose one.

Bootcamp 6 on Macbook Pro 2015 does not work
Hi all
I just bought a 13 "Macbook Pro retina 2015 and I try to use bootcamp version 6 to partition the 512 GB SSD 2 x 250 GB drives and one for Macintosh HD for Windows 10 but bootcamp fails every time.
I start the bootcamp assistant and the first screen's INTRODUCTION that gives just the info about backup etc.
I then select continue and get a second screen asking for the path to the iso file of Windows and what size I want the partitions I divide also (250 GB to 250 GB for Windows and OSX.
I then press install and it takes about 1.5 hours to partition the drive and download the Windows support files - SO FAR SO GOOD.
Macbook Pro then restarts and that's it - I am left with a blank screen and all I can do is, turn off and on.
When I look at the SSD then I see it has been partitioned to 250 GB for OSX and 250 GB for windows but while do I do?
If I restart Boot Camp Assistant it gives me just a button to RESTORE the SSD drive in OSX partition
I tried several times but just keep going in circles...
Can someone help me please?
Thank you very much
Mike
1 do you still have the OSXRESERVED partition on your drive?
2. what version of Windows you are trying to install?
3 Please manually download drivers BC6 and check the Bootcamp.xml for the Version of the product line.

Hello
It is not easy to say what the problem is here. Have you noticed something strange with LED power control? It is also possible that the electronic power supply do troubled. Try to talk with authorized Toshiba and explain the situation. If you open only one Notepad, uneducated, it may be simply worse.
Graphics card cannot be updated as on desktop computers. I put t know how it is on this model laptop but the graphics card is fixed on the motherboard and cannot be traded.

MacBook Pro (2014) does not charge despite an orange light when plugged
Hello
So my 2 year old Macbook Pro (retina) does not load when it is plugged in - spite, projecting the orange light. I have a battery (20%) and it is reduced whenever I use it and will be soon drained.
Some of the things I've tried
-Reset SMC - tried but no change after
-When I use the mac when it is plugged in the battery icon in the top bar done see the support - but there is no increase in % of the battery. Continuous use it starts to fall.
-During use (and what battery is plugged) - I checked the report system (about this Mac section) - in the energy sector - it is said does not charge (despite being connected, the orange light and the symbol in the top bar)
What do you think guys that it is? MLB? Battery?
What I have to replace or can it be fixed?
If you have the Apple store, take the machine evaluation. There is no charge for this, but you need an appointment. The first thing I would check would be the cable. You have another machine to test this with.

Plugged not charging - laptop does not work on battery
I have a Lenovo laptop running Windows 7 less than a year. But it does not work on battery now. Battery level icon said: ' 87% available (plugged in, does not support). Multiple, several times I tried to remove and re - insert the battery, restarting, uninstalling the 'Compatible Microsoft ACPI Control method battery' driver through the device, new material to re Analysis Manager - find the battery and re-install the driver, over and over again. Nothing works for me--and if I unplug the AC adapter, the laptop just dies instantly. Basically, it is as if the computer can see the battery, knows it is there and has the power, but don't give her a load or pull everything current. What is the reference for this? Anyone? Help, please! Thank you.
