Hi everyone.
I'm going crazy with a problem that affects my MacBook Pro 17 "(Early 2011).
Problem description:
If I use the Macbook so that does not require much performance everything works fine, but when I need to perform tasks that require more resources and processor passes 3.0 Ghz the light on the MagSafe goes off and the battery stop charging. When this happens I have to remove and re-connect the MagSafe the Macbook, but after a few seconds or minutes the problem recurs until the fourth or fifth time this does not work anymore, only works if I disconnect the MagSafe from the wall (if I disconnect the MagSafe on Macbook does not work, very strange).
I've realized attempts with three batteries, an original Apple (95wh) and other non-genuine (Sloda) purchased on Amazon (95wh) and both have the same problem, besides I tried with a non-genuine battery 65Wh (Lizone), the problem does not occur, the battery is charged quickly, but the processo only works on 0.8GHz.
I've also tried with two MagSafe adapters (85w and 60w) and the result is the same, low energy provided to Macbook with (2.0~4.0 Watts).
The coconutBattery reports that the batteries with 95Wh are being charged with 2.6~3.9 Watts and battery 65Wh with 40~55 Wats. It would be a coincidence that two batteries of 95wh (one original and one not) with the same problem? Or could be a problem with logic board when need much power?
This problem always happen if I need execute heavy tasks, when CPU increase the frequency for 3.0 for example, if I start the system and don't execute anything this problem don't happen.
Edit: a detail is that when Macbook stop charging, the MagSafe also is not detected anymore until I disconect from the outlet and conect again.
I've a MagSafe DC to replace in my computer, but I don't know if this is the problem. I must be sure of the diagnosis because an original new battery in Apple (Brazil) costs about R$ 1,400 ($ 500).
Thanks for help.
