New MacBook Pro & Slow Sleep

Hello all, just received my very first MacBook Pro. I bought my first Apple ever about 6 months ago (2.0Ghz C2D MacBook) and had to upgrade to this baby. I'm loving the thing so much more than my MacBook, it is hands down 2x the computer. The only thing I have noticed that is not as great as the MacBook is the sleep mode on the MacBook Pro. When closing the lid (and opening it) it just takes longer to sleep and wake than my original macbook did. After doing some research I read about how the new 2.4Ghz C2D's have the new Santa Rosa architecture etc... Well it mentioned the new chipset features some kind of smart (or maybe they called it intelligent) sleep mode......could that be what is slowing down the sleep process??? Anyone?

Kev

MacBook Pro 2.4Ghz Core 2 Duo, Mac OS X (10.4.10)

I have noticed this too.

Is it just a change in the hardware and it doesn't do it as quickly as the G4 PB?

The added time for sleep is simply due to you having more RAM. As part of the Safe Sleep procedure the contents of RAM is copied to hard disk to preserve its contents again all possible power related issue. This however means that the more RAM, and the more RAM that is in use, you have the longer this will take.

I have a SR MBP 2.4 with 4 GByte of RAM, which needs 25 seconds to go to sleep after I've closed the lid, and some 3 seconds to wake up after I've opened it again. Doesn't matter whether I have lots of apps running or if the system is idle.

Closing the lid lets it go to sleep mode, but definitively not to safe sleep (or deep sleep, as some refer to it). The system will enter safe sleep automatically in case it runs out of battery power during sleep mode. If that happens one will see a progress bar during the next start up of the system, which indicates that the previously to HDD saved content of RAM is written back.

BTW, my C2D MacBook with 2.0 GByte of RAM takes only some 3 seconds to enter sleep mode. Looking at Ned's post my MBP should take only some 6 seconds to enter sleep mode.

I don't know why the SR MBP takes so long to go to sleep. I don't think it's the OS alone (had the same issue with 10.4.9 and 10.4.10). It might be because of the chipset. Either a pure hardware issue or a combination of the new hardware and Mac OS X. IMO it's not related to the amount of RAM.

Just my 0.02$.

I have been having problems with waking from deep sleep and am considering returning the system to normal sleep and relying upon it auto-deep-sleeping if power gets too low.

Thanks.
