apple macbook pro 2011 charger replacement

I was able to reproduce this at the apple store on a 17' 2011 model as well but I'm curious if this also happens on the 15 and 13 inch models. I have a 2009 MBP 17' C2D 2.66GHz, and although the recharge time goes up by 20-30% in the exact same test, it at least still charges the battery. Now watch the battery indicator's recharge time value and you should notice that it'll start going up significantly in time and at some point it'll say 'Recalculating' and eventually it'll give up and say 'Not Charging'. The 'yes' command basically causes an infinite loop of the letter 'y' to be display in the terminal window which also taxes your CPU in addition to the video playing in Hulu.ħ. Then open Terminal and type the command 'yes' (without the quotes) and hit enter. Open up safari and go to Hulu and play any TV show to drive up your cpu usage.Ħ. Plug in your MagSafe and let the recharge time in the battery indicator calculate and stabilize (give it about 2 mins to get a stable time value).ĥ. Change your battery indicator icon in the menu bar to display the info as 'Time'.Ĥ. Let you battery drain to about 80% or less.ģ. Here is a simple way to try to reproduce the problem:ġ. I figured that this may be due to a design flaw where the power unit cannot supply enough tower to feed a CPU that's being somewhat taxed (i'm talking about 25-50% usuage) and recharge a battery. I thought that I may have a bad MagSafe so I tried the one from my 2009 MBP (both are the 85W version) and bam same problem. Then at some point the magsafe light went green and the battery indicator showed 'Not Charging'.

I was at 5% battery life and the computer was plugged in recharging and the battery indicator all of the sudden went from somewhere around 2.5 hours recharge time to 10 hours to 15 then 20 hours. I noticed the giant fluctuations in time when I booted one of my VMs which used up like 15-20% overall cpu usage. In summary, I noticed that depending on CPU usage, the battery reacharge time will greatly fluctuate to the point where the laptop just stops charging the battery.

Hey everyone, I discovered a problem on my 2011 MBP 17' which I was told that 'it's perfectly normal' and I want to see if you guys can reproduce it on your new 2011 models as well (please indicate your screen size).
