I have read somewhere that Apple does this " underclocking" intentionally, for safety or marketing (to buy a new battery) reasons. I tried the interrock's (the 10th post) guide but it does not seem to work correctly and caused me a kernel panic related to the SleepEnabler. Moreover, the mouse speed significantly increases. By "VERY slow" I mean - games become unplayable (FPS drop from 60 to 6) and kernel_task starts using more than 500% of the CPU. Nevertheless, the main problem is, after some time, the laptop becomes VERY slow. Now, every time I plug-in the power cable, it starts straightaway (even without pushing the power button), turns off after a few seconds, and then starts normally.
#MACBOOK OS X BATTERY PRO#
and on the off chance that some dear soul at Apple gives a crap and might actually troubleshoot and resolve the problem.Recently, my battery randomly died and I had to disconnect it, otherwise, my computer would not properly turn on (MacBook Pro was restarting itself and turning off over and over again). So, I'm posting this mostly as warning to others with similar battery/charging/keyboard/trackpad problems. OSX upgrades - several upgrades since this problem started, and no resolution. MagSafe connector cleaning - all clean, no effect. MagSafe charging adapter swap - no effect. MagSafe daughter board replacement - I've done this previously for troubleshooting wife's Macbook Pro. Main board replacement - too expensive a "fix" for a problem that should not exist.ī.
which means I've done this 5 times and the method failed once) and (3) replace battery, which has worked 1 of 1 times (when battery disconnect didn't resolve issue).Ī. My only remedy strategy thus far is to (1) connect USB input devices if MBA is still working but keyboard locked, then shut down and reboot (50% success rate) (2) disassemble MBA to allow disconnection of battery from main board, then reconnect and try restart (80% successful. I lump the battery/charging/keyboard/trackpad problem together because the symptoms ytpically have direct 1:1 association. My assumption is that Apple is too lazy to troubleshoot this (apparently - per google results) common problem. I have created cases for it, chatted with Apple online and at store, had the device tested at Apple Store 2x and submitted for fix. Battery "X" appears, charging function stops, no battery recognized, and sometimes the keyboard+trackpad locks up and requires external USB keyboard and mouse if the device is still running. Mine: mid-2011 Macbook Air (MBA) that has exhibited power/charging problems repeatedly for 3 years. I have read this thread:, however it is concluded that the problem in the thread was related to the battery which is not relavant to my problem, however as advised on the thread, I established the system report for my battery as shown:Īnyone able to advise on what is going on with my Macbook Air? Any help will be very much appreciated. My Macbook Air is now Mountain Lion 10.8.2 however my Macbook Air still requires the charger before it can turns on and the charger will always have the green "fully charged" light turned on.
#MACBOOK OS X BATTERY UPDATE#
I re-installed the OS, refreshed the system and update whatever that is required to be updated. I arrived to another conclusion is that my Macbook Air battery was alright and that my mother board could be at fault. Īssuming my battery was at fault and with the help of some contacts, I replaced my Macbook Air battery with another battery to understand that I had the same problem with the new battery. When the Macbook Air (with the charger attached) is on, the battery indicated a cross sign while my charger had a green "fully charged" light. When I attempt to turn it back on, it was not able to switch it on until I re-attached the charger. My Macbook Air battery was charged in full, I was using it when I detached the charger to have it shut off without any pre-empt warning. This happened to my Macbook Air 3 weeks ago:
