Hello everyone, I bought MacBook Air November 2013 in India. I am facing the same problem in my MBA after 6-7 days of buying date. Since it is my first device from Apple so I am following all instructions by the resellers and service center persons.
First I spoke to the reseller, he suggested me sometimes due to third party apps it may happen. When it happened again then he suggested me to go to service center. In between that I selected this discussion on Apple support community and started to get the comments about this issue. Then I chatted online with apple persons they instructed me to check settings of SMC and PRAM and suggested to go to service center. Then after, 3 times I have taken my MBA to service center:
1st time: they changed the settings in it and gave back to me by saying to observe the problem.
I observed for 2 days problem occurred and I informed
2nd time: they kept it for 4 days with them to observe and gave it back by saying that we have fresh installed the Mac OS10.9 since this issue was due to I have updated the Mac OS from 10.9 to 10.9.1
Within 4-5 days it happened again with one more problem of showing battery drain significantly by spot light. I continued to observe these issues for few more occurrences. In between that again I chatted with apple person and discussed both the issues.... amazing... again he told me the same settings as previously and observe.
3rd time: I took it to service center and told compete issue about the discussion with apple persons too. They kept it for two days and simply said that we have to chat with Apple technicians then only we say something. They chatted with Apple technicians and suggested me to keep the machine as it is till the Apple people update the firmware… When I asked… How much time it will take…? They said, “Do not know”!
Interesting point is that in front of service center person I showed this issue how screen crashes and how the battery drains happening and showing energy used significantly by spotlight. Even then those persons told me to wait for firmware update by Apple.
After take from service center, one more thing is happening with my MBA if I put my finger in front of webcam brightness of display goes dim.
When I asked to replace it or upgrade it to another machine then they simply raise their hand and we can do nothing for this. And told you have to speak with Apple persons
Now what to do? I am helpless…!!!
