Ok, the situation is that when the battery gets empty my Macbook doesn't use Safe Sleep and go to sleep. It just shuts down completely. What's wrong? Is the battery malfunctioning? Should I take it for repairing or what?
Yes, I have to press the Power button and then it boots up normally. Safe Sleep isn't working. And when my battery reaches its last it notifies me that it's gonna go to sleep in few minutes if i dont connect the ac adapter. But then it just shuts down completely.
Be happy it's just the battery. I had the battery replaced today by the "genius bar" guys after my computer exhibited the exact same symptoms. Just shuts down randomly when battery is running down instead of going to sleep or giving warning message. Heck, mine would go from 100 down to 90, then boom, shut off.
They replaced the battery, but I still have more problems. Over heating, locking up, rebooting, shutting off, stuck cursor (no mouse response), and more. They just want to keep on fixing it. Strange thing is, I get it back and its not fixed. I have had enough of the not genius bar, and apple care (or apple doesn't care).
