    I just got my MBP back from Apple because it wouldn't sleep at all; they replaced the logic board and a few other things. It will sleep now, but only with Firefox closed. If the browser is open and I walk away from my computer it won't sleep -- is this normal? Has anyone else noticed this? :eek:

    no that's indefinitely not normal but if you just got it back from Apple, why not call and tell them the problem?

    Because they will just tell me it's a software issue; it sleeps fine if Safari is open or iTunes or any of the other applications. It just refuses to sleep with Firefox open.

    Can someone do a quick test for me? Change your battery energy settings to sleep after 1 minute of inactivity. Open Firefox and disconnect the power cord. Let the laptop sit for a minute or two and see if the "pulsing" sleep light comes on. My screen will dim and seems like it's sleeping, but if the browser is open the "pulsing" light never appears and I can hear the fans spinning inside.

    Please test this out for me!

    Just opened Firefox (along with Vmware and XP) and it went to sleep when it was supposed to. I recently had a similary problem while running VMware and it was due to it running some background processes. Once XP suspended, it would go to sleep.

    I've noticed with Firefox that certain pages use a ton of resources, and thinking maybe your home page or wherever you're leaving the machine is running something. My Firefox homepage is Yahoo and it allows the machine to sleep. When I'm in the Yahoo mail page, resources run very high and doubt it would sleep.

    Thanks for the reply. At first I thought it was that because I tested with about 20 tabs open. Then I closed all the tabs and went to It still refused to sleep.

    I'm afraid Apple will tell me it's a software related issue (3rd party at that), as they just fixed it (by replacing the logic board) and it will sleep fine with Firefox closed. I'm thinking of reinstalling Firefox tonight and trying again; then a complete format if that doesn't work; then back to Apple as a last resort.
