Battery-No warning

When I don't have my mac on the adapter, my mac shuts off without warning when the battery drains, and I loose all my work. It used to give me 15 minutes warning or so, so I could save my work.

I don't know what to do to get it back.

Apple, Mac OS X (10.4.7)

just have got the 3rd replacement of my macbook battery. after installing the first 3 times "going to sleep after the battery warning" worked.

the 4th time my book shuts down immediately (after battery warning and draining to 0%)

what seems strange to me is: in the beginning battery capacity was around 5200mAh. After failing to go to sleep the capacity is constantly between 5600 and 5700 mAh.

No system change, no new apps installed.

I consider to live with this failure.

I have tried your advice and it seems to work, at least one time. We shall see..

Apple Store replaced my battery (I had to show them screen shots I took showing date and Apple Profile charge cycles to prove I was having problems prior to 300 cycles.) They checked some stuff online and decided to give me a free replacement (my Macbook turns 1 year in October.)

So far it is working although if I have the energy status turned off on the menu bar, I get no warning of low battery. The Genius didn't know if this was normal behavior and I can't find anything on this at Apple.

I hope I don't have to post on this subject again. I know some of you have had 2 or 3 replacements only to have the same problem again. I still think it has something to do with that 2.2 (?) battery update.
