Macbook Pro shuts down when the battery has drained, instead of sleeping.
Hi.
This is regarding the Macbook Pro's actions when the battery drains completely ('06 - '08 that I know of). In older Powerbooks, the mac would just go to sleep when the battery had drained. With the MBP's (running 10.6 or 10.7), the machine shuts completely down - losing anything not saved, and requiring a full restart and opening of all my work again. I've been reading through other posts on this topic and tried various solutions posted, but nothing has changed. Has anyone found a consistent solution I've missed?
It doesn't have anything to do with "Restart after power failure" being selected as someone suggested. I've always had that selected on both laptops and deskstops since forever, and it's not relevant.Also, zapped pram, reset SMC (tried the one for unibodies as someone suggested, but no change), etc, etc.
I'm on a MacBook Pro early 2008 (A1260) running Snow Leopard. It also was happening on my niece's MacBook of the same year running 10.7.x. I do have a new replacement battery installed, not a cheapie one, but not an apple one either. It has been working fine, no issues though - is lasting for 3 - four hours depending upon what I'm doing. This is very dissappointing if it's going to be the way Apple laptops are going to handle battery calibration (or just normal usage while on battery charge). I've always trusted my Mac to take care of business when in such situations, and leave me high and dry like it is now.
Thx.
