Macsafe 85w still not enough when running Heavy program on Macbook pro 2011 Quad Core

Is there any official announcement from apple on how macsafe 85w works & design flow or diagram..??
We know the magsafe 85w is not enough to run macbook pro quad core i7 and their family.. But there must be some reason why apple only allow maximum 85w only.. rite
I run this multiple test on my Macbook Pro early 2011, 17" 2.2 Quad core i7, 8G ram, to proving that the 85W is not enough.
-Im running this test on both OSX & win 7
-the battery capacity is 20% when i running this test
-the power adapter "macsafe" is plugin when i run this test
1) macsafe 85w turn to green to stop charging when rendering HD movie in Final Cut pro 7 in OSX ( but then it will turn to orange to charged again after you cancel the render)
2) macsafe 85w turn to green to stop charging when playing high graphic game such "Razor F1 2010" in Win 7 ( but then it will turn to orange to charged again after you quit the game)
3) macsafe 85w turn to green to stop charging when editing AVCHD on Sony vegas Pro 10 in Win 7 (it will turn to orange to charged again after you quit the program)
4) when the baterry reach 100%. then I run all of 3 heavy program above.. the baterry will drain slowly until 93% then it turn to orange to charging again.
(this will happen only when you run heavy program) 85w macsafe itself also not enough to run these program.. still need little battery support..
As i know this will happen to all macbook pro since before Quad core model. You must run heavy program, then you can determin this systoms..
Lastly, I really hope that all of this symtoms are the "macsafe work design", & not the macsafe fault... & really hope this symtoms will not damage the battery because regullaly charge on & off.
Maybe This is why new macbook pro design,, you cannot take out the battery... It still need the battery support also, while plugin..
Thanks &
Sorry broken english..

"Maybe This is why new macbook pro design,, you cannot take out the battery... It still need the battery support also, while plugin.."
Yes — but only when you're working the machine very hard. Most of the time, 85W is ample.
"But,, we need the official announce by apple regarding this issue"
No you don't. That's how it works. What good would an announcement from Apple do you?

When i boot i get a flashing folder with a question mark. disk utility doesnt work or read my harddrives to boot with. i installed a new SSD and its not reading that either. i have a macbook pro 2011, any help?

So I came to this problem a while ago. M ycomputer basically froze so I was forced to shut down by holding the button down. When I started it up I got the flashing folder with a question mark. I started it up holding down the command and r keys which brought me to disk utility. Although my computer doesn't read that I have a hard drive to start it up. When I click on the disk utility app, I cannot verify or repair anything either. The buttons won't allow me to click on them. It also shows "Mac OSX Base System" which shows I have files and what not saved. I had been told that I need a new hard drive so I bought and manually installed a OWC SSD 240GB drive and when i booted the computer up it booted up yo the operating system fine with all my files and what not on there. After about twenty minutes, it froze again. I forced a shut down, restarted and the same thing happened. I am not able to choose my SSD to boot up, although thats probably because it doesn't have an operating system installed on it??
i have a Macbook Pro 13" 2011
any help would be great, I'm overall confused.

ryansaint11,
this isn’t Apple support; this is a user-to-user forum. We’re just fellow users of Apple products here.
If you want to boot from your SSD, then you should put the SSD where your HDD currently is, and put the HDD into the optical bay. (That setup will also get you the best performance.) At the moment, you’re still booting from your HDD. Note that you will need to format your SSD in Disk Utility [with the “Mac OS X Extended (Journaled)” format] so that you can install OS X onto it.
Since you have an Early 2011 model, it might or might not have originally come with grey installation DVDs. You will be able to find out whether it did or not by trying to use OS X Internet Recovery to install OS X onto your SSD. If it does not work, or if the installed OS turns out to be Snow Leopard, then it will have originally come with the DVDs, and you should purchase a replacement pair of DVDs from Apple or iFixit; those discs will have your MacBook Pro’s Apple Hardware Test and its iLife apps. If the installed OS turns out to be Lion, then it will not originally have come with the grey installation DVDs, and your Apple Hardware Test will be installed along with Lion, and your iLife apps will be downloadable from the Mac App Store.

Disconnect sound when running windows 7 on macbook pro 15"

First of all, here are some of my computer specifications:
     Using macbook pro 15"
     Mountain Lion OS X
     Windows 7
When I use windows 7, I occasionally here the disconnect sound as if I'm removing something from the USB port. This happened more frequently this evening when I switched from using the mac operating system to the windows operating system using bootcamp. I have had my computer for a month, and this has just recently started happening. I have run upgrades for both the mac side and the windows side on the 24th of October. I take good care of my computer and have not done anything to cause harm to the USB ports. Please help.

I have exactly the same Macbook Pro as yours but mine has the matte screen. I bought mine in September 2006 but it is classed by Apple as the 'early 2006' Macbook Pro because they released the 'late 2006' Macbook Pro in October 2006, a few weeks after I bought mine :@. As I said in my post, http://discussions.info.apple.com/thread.jspa?threadID=2307301&tstart=0 , Windows 7 is working fine on my Macbook Pro, so it should work on yours. Good luck!

When apple is going to have an update for mountain lion to fix the spinning wheel at start up and when a shut down my macbook pro 2011?

I bought a 2011 macbook pro after clean it up and reinstal Mountain lion, i did an update since then, whe i start up and shut down the computer gets a spinnin wheel which takes forever. I have read about this problem but i'm new at mac, and seem to be kind of complicated repair it. I'm wonder if anyone knows if apple is doing something to fix this? macbooks arent chip and i shouldnt go thru all the the time consuming to get it works how sopose to.
if some one knows anything or if there is anybody who can guide me step by step on how to fix this, i really will apreciate that.
thank you.

As cbs20 says...
Boot up holding command-r keys into your Recovery Volume.
The screen should give you these choices...
Restore from TM backup
Reinstall Mac OS X
Get help online
Disk Utility
First run Disk Utility Repair Disk, if you get errors run until no errors reported or reports "the disk cannot be fixed". Then, choose Reinstall OS X. This will be an install "in place" and shouldn't effect any of your own data or settings.

Still not able to input video on my Macbook Pro

I have a new MacBookPro. I used to be able to use my Dazzle Hollywood Video input device, to import tapes into my Imovie program. Since I got the new computer I cannot get Imovie to see anything other than the Facetime camera. I cannot switch to the Dazzle unit. Is there some trick to getting my computer to see the VHS tape?
I have tried everything I can think of .
Thanks in advance for any help you can give.

X-fi fatal1ty device not detected when running speaker selection wizard

Gx-fi fatalty device not detected when running speaker selection wizard? ?
System is a custom build, based off an ASUS A8N-SLI Premium, with two GTX7800 display cards. in a SLI configuration
Fresh installation fo Windows XP Profesional with SP3 slipstreamed.
Origional CD fails to detect the card, claiming a supported device is not present.
This card has worked prevously, and is verified as fully functional in windows Vista. ?
Please note Windows Vista can not be used.
I have tried about 30 different versions of the drivers (each on a clean installation) and used both clean and dirty boots, and nothing is working.
Before anyone points me at other threads in this forum, please note i have been scouring this forum for the past week trying every sugestion there is, and I have raised a ticket with Creative (who despite the prommise of a 2 day responce, have yet to respond)
I have tired multiple versions of the NForce drivers, NVidia display drivers, Creative Drivers, Bios updates, Chipset hacks and more.
does anyone hav a sugestion that is not already posted on this forum.

Tried it on one of the spare PC's in the house earlier (Nforce 2 based) - still no recognition of the card whatsoever, it's as if it doesn't exist.
I'm guessing that the card is pretty much toasted eh?

Hi I do not want iTunes to open up automatically when I turn on my macbook pro. I tried going to System Preferences Users and Groups Login Items and then I took iTunes off the list but it still opens up automatically when I turn on my laptop.

Hi r,
Make sure you close iTunes before shutdown. And you're quite welcome.

Text keeps disappearing when I select it to make type at all / make changes / edit. Type tool is not working. I am running CS6 on a Macbook Pro Retina (which I am hating!) 10.9.4 - wish I'd never upgraded.

I have followed the Apple Support instructions I did it 3 times and this message always appear: "The program can't start because MSVCR80.dll is missing from your computer" and 'Error 7' but still not able to run iTunes. Anyone have a suggestion... Please!

Try completely removing and reinstalling iTunes and all related components; you may need to do this multiple times. It won't normally affect the iTunes library, but that should be backed up anyway.

SAP Gateway- environmental variables not loaded when running brconnect

Hello
i have installed the Sap gateway on MSCS
and the RFC check in sm59 is successful,
However when i run a job in db13 it fails with "brconnect is not recognized as ......... "
<sid>adm has all environmental variables set correctly
SAPService<SID> has them too
when i run brconnect on OS level it works fine with <sid>adm and SAPService<SID>
however if create a brconnect.cmd file where i specify the command as
SET ORACLE_SID= ....
SET SAPDATA_HOME=....
C:\windows\sapcluster\brconnect.exe ...........
and run it in sm69 it works fine
Any ideas how to solve this, seems the variables are not taken when running sapxpg
, i don't want to edit the SDBAC for every command
P.S
set from sm69 returns only the system wide variables, however i have the two systems on this host, and can not make the environmental variables for ORACLE_SID and SAPDATA_HOME system wide as this will cause problem with the other sap system
Edited by: Yavor Markov on Apr 12, 2010 6:07 PM

Hi Markov,
Can you tell us with which user id you have installed SAP as well as check the sap services are running with which user id, if it is not <sid>adm then you have to check the environment variables of that user.
Also you can try adding c:\windows\sapcluster in PATH environment variable.

HT201317 When I view photos on my devices some are not oriented correctly. I used Picassa to turn all photos upright and then copied those photos into the upload file but they are still not corrected when viewed on my devices (ipads)

Generally I would not use Facebook for sharing any photos, it compresses the photos substantially, and when you have shadows and dark colours you get visible "bands" where there should be subtle gradients, ie at sunsets and sunrises.
It sounds like you are using two methods to upload to Facebook:
1. Sharing from within Aperture, which basically syncs Facebook with your Aperture album, so any changes made at either end gets synced, hence the deletions from Albums, although the original file should still be in your library, just removed rom the album. It is like a playlist in iTunes.
2. Exporting pics and uploading to Facebook from the browser.
I am not sure how method 1 gets compressed, but I know that uploading hi-res jpegs to Facebook using method 2 results in poor quality images.
I wouldn't even bother comparing option 1 or 2, and they will both be poor images once you view them on Facebook, as opposed to viewing uploaded images on proper image sharing / hosting sites.
Your problem is not with Aperture, it is using Facebook for showing your work.
If you export pics form Aperture at high res jpegs or TIFFs your images will be fine.
If you insist to use Facebook as your way to share your work, then your workflow should be this:
1. Right click images you want to share.
2. Select Export version.
3. Export as 100% size and ensure the export settings are set at 100% quality.
4. Upload this pic into Facebook.
This will get you the best image size and resolution on Facebook.
See how you go.

How do I enlarge the "presenter notes" window when running my presentation on an external display?

In the latest version of Keynote, the "Presenter Notes" window is a small horizontal field at the bottom of the presenter's computer screen. Only 3-4 lines of text can be seen. This means that when you have a few paragrahs of notes, you have to scroll through them as you are presenting. This is very cumbersome. In the previous version of Keynote you could change the relative size of the slides versus the "presenter's notes" boxes when running a presentation on an external display, but in the new version, I can't find a way of enlarging the "presenter's notes" field.
Also, in the new version, the preview slide doesn't show the initial text on the next slide if that text emerges as a "dissolve in" build when you advance forward through your slides. I always have the initial text on my slides automatically "dissolve in" after each slide transtion. But in the new version of Keynote, when in presenter mode, I can't see any of the text on the "next slide." This makes it difficult to anticipate what slide comes next . . . without going to the Navigator. Does any one have a solution for this?
Thank you.

I figured it out with the help of a post from a few days ago. Although posted for a different problem, I followed these steps from Cornelia-I and it worked like a charm:
You can change the link of LR to the images from the network drive to your local drive, best done on parent folder level: right-click the highest folder in library left panel, and choose update storage location. In the opening dialog window point it to your internal folder.
