    So I just got a new (to me) MBP refurb... it works great, i'd say 95%... but that last 5% is really driving me nuts.

    I like to run my laptops lid closed in the office (don't gimme any grief, it's not going to melt my display).

    But this new one won't do it.

    I connect the display and an external keyboard and mouse, and then close the lid to sleep the laptop, then I wake it with the keyboard/mouse, and it flickers to life (like my blackbook), but goes immediately back to sleep rendering it useless.

    I've reset the PRAM, and tried to delete preferences, any other ideas?

    I'd rather just get it to work as it should. This thing costs good money, it should work as described.

    I'm really looking for a way to fix it myself so I don't have to warranty it.

    isn t there an option in system prefs under energy saver to disable sleep?

    You shouldn't run it closed anyways, the heat escapes the keyboard and will ruin your screen.

    Just my opinion. I'm not sure why it wouldn't be working.

    The heat doesn't escape the keyboard. Running lid closed is fine for the new MBP, and even most aluminum powerbooks. It's a designed feature.

    I have seen MBP's running for days on end with the fans running at 100% and the screens are no worse for wear.

    I'm running mine lid closed right now. There is absolutely nothing wrong with doing this. I'm sure I put more use on mine than most users and I've never had a problem doing this. The heat escapes through the rear, where the fans are...

    Now, is your MBP plugged into the power cord when you close the lid?

    The ONLY way you can fix this is by doing an archive and install, and NOT install the Leopard Graphics Update.

    Tons of people have this problem on the Apple Discussion Boards (including me :( ).

    Also Apple is aware of the issue, and it will be fixed with 10.5.3 (whenever that is :hsugh: )

    Hey, so it's a free country and all, but have you guys ever actually felt the topcase of an MBP under load? Specifically the metal strip just above the F2-F3 area where the processor is? That fucker is hot to the touch, regardless of how much heat is channeled away by the fans. IMHO you'd have to be nuts to put a thin, thermally-sensitive polymer screen so close to a heat source like that.

    Apple does it all day long.

    :dunno:

    I see engineers do it every day, running cad, compiling, and whatever else you want.

    You can surmise and estimate all you want, but the results don't lie.

    This is not what I wanted to hear.

    Fortunately, 10.5.3 has been well seeded to devs so I can hope that it will be out soon.

    sure, but Apple probably doesn't give a shit about their own hardware breaking either.

    There's a lot of failure modes that can creep up over time in a situation like that, especially if the thermal loading is cyclic, which it likely is when computing.

    Remember, Apple hasn't even properly applied the thermal paste to the CPU die in these MBPs, they're already less efficient at removing heat in reality than they are on the drawing board. Maybe if the topcase wasn't getting hotter than what it's spec'd out to be that would be one thing, but in the real-life shipped units the thermal efficiency of the cooling system is compromised by excess thermal paste. I remember a couple guys who opened their core duo MBPs to reapply the paste properly, and found that they reduced the core temperature by over 10°C under load... that's a large discrepancy between design specification and real-world performance.

    Ya it sucks. There is also a bunch of other sleep/power related issues with that damn update. If I turn on my computer with the external display attached before I power it on. The max resolution my 24" will display is 1200x800. Also if I close the lid on the MBP, when I reopen it both displays will remain blank.

    Complete pain in the ass.

    what sucks is i have the exact opposite problem. when the lid is closed, it periodically wakes up and then goes back to sleep, shit is fucking annoying and it seems to be a common problem

    try using caffeine to keep your mbp awake
