| MacBook Sleep Drains Battery
Maybe I'm just overreacting, but I think there might be an issue with my MacBook's sleep mode. It seems as if my battery drains a significant amount when using sleep mode. For example, last night I but my MacBook to sleep with 97% battery. When I awoke (7 hours later) my battery was at 88%. Is this normal for a MacBook? I'm under the impression that sleep mode should drain very little, maybe 5% tops during that period of time.
Now I have tried a few things to remedy the problem. I have insured nothing was connected to the MacBook, and I have put it to sleep manually from the Apple menu with the AirPort and Bluetooth off. Tonight I'm going to try putting it to sleep with the 512MB of RAM that came with the MacBook (I upgraded to 2GB). Any other ideas? -- Xbox Live Gamertag: cm50 |

| reply to cavemonkey50 The Macbooks may not be able to turn off as much as the PPC laptops when they sleep. I know with my iBook it moves maybe 1 or 2% with it asleep for like 5 hours. -- "Here's to the crazy ones. The misfits. The rebels. The troublemakers. The round pegs in the square holes." |

| reply to cavemonkey50 That sounds a little bit higher than mine, but I still have the original 512MB installed. Considering what the Sleep function actually powers, it's probably right on target for the amount of RAM you have installed. -- Once you go Mac, you'll never go back. |

| reply to cavemonkey50 That does seem a bit more than my iBook, but it doesn't seem too outrageous. Since the machine has to leave a few things powered to be able to instantly resume, memory is going to eat your battery life. I would guess the more modules you have, the more battery life it will eat. Of course I think those come with 2 modules anyway... |

| reply to cavemonkey50 Thanks for everyone's opinion. Last night I put in the original 512MB that came with my MacBook and I only lost around 2% of my battery. So the extra RAM must be the cause of the abnormal drain.
Now that I know nothing is wrong with my MacBook, I can rest easy. While I do lose a fair amount of battery power in sleep, I'll just have to keep that in mind when putting my MacBook to sleep for extended periods of time. Thanks again. -- Xbox Live Gamertag: cm50 |

I agree with the assessment of the other members here, this sounds very normal to me.
Every laptop I've ever owned has had battery drain like this in sleep mode.
Quite frankly, I rarely use sleep mode on my MBP. Tiger seems to boot in less than 30 seconds, so I never see the need for it. |

When you put your laptop to sleep, it backs up your RAM to the hard drive. In the case you remove your battery to replace it or your battery dies when you start it up the next time, it will boot up from the hard drive from hibernationn. But as jwsmiths4 says, its not user activatable. |
