    PowerBook Sleep

    I have a PowerBook that I will hook to an inverter, is there anyway to get the PowerBook to automatically sleep when it gets no power and to wake when it does get power?

    Edit: or even a button I can rig so that I just press the button and it sleeps, I press it again and it wakes up.

    Yes...to both. I don't have my 'book with me, but there are some Cocoa functions that can achieve what you want (could be built in to the front end, or as a simple standalone "monitor"-type program). I will post an example project later tonight or tomorrow that has both methods. Also, when hooked to an external screen, the pBook requires "AC" power, correct? So if it is hooked to an external screen and loses its power, does it go to sleep or flip to internal screen (I can't remember)?

    --m

    // edit:
    One question though, if the book is sleeping, how to you push the wake up button? Or do you mean a physical Powermate type button?

    powerbook sleep

    Here is my experience with powerbooks in cars.

    I've used three, starting with a PB2400 "Comet", a 15" Titanium and a 12" aluminum.

    They all behave the same. First of all, use a dc to dc converter instead of an inverter. The smallest one I've found is from lind. An inverter will work, but it will generate more heat and probably be larger.

    If you're using an external monitor, start up the powerbook with the lid open and the dc converter turned on then close it immediately. Otherwise leave it open.

    Let the 'book boot up.

    When you turn off the power to the converter, the powerbook will go to sleep. When you power it back on, it should wake up. In some cases it might need a click or some other input from the mouse, keyboard, trackpad, whatever you are using for input to wake up.

    The trick is to apply power to the powerbook before turning it on.

    Good luck.

    I have done a bit of experimenting. I set in the Energy Saver the "Put the computer to sleep when it is inactive for:" to one minute, which solves a lot of my problems. When power to the PowerBook is cut off, after a minute, it went to sleep by itself. When I plug it in, it does nothing but this is a start and it solves a lot of problems. When you turn your car off, after a minute it shuts itself off (I could set this to any amount of time). If I set it for 5 minutes, I can go for gas or whatever. I do have the problem of the display switching to the internal display. I haven't tried it but I don't think it will do anything because the lid will be closed.

    This is what I have in mind.......
    PowerBook G4 867Mhz
    8" Lilliput VGA (found in MP3Car.com Forum store)
    Running C-Car Project
    Bluetooth Apple Keyboard and Mouse
    Something to power those, I'll look at Lind (is there a solution to power the LCD as well?)

    Another question would be if I can wake up the PowerBook using the touchscreen. I'm trying to avoid using the mouse and keyboard but will have them stashed just in case.

    Anybody see problems, alternatives, anything to help me?
    BTW, I'm not really looking to get a good deal on the LCD, SUPPORT THE SITE!!!

    Has anyone used the adapter that came with it, I've heard negative things about it such as it shortens the bulb life. Are these things true?

    Actually, also recommend me a LCD that will work with a PowerBook with relative ease.

    I can wake up my powerbook using the touchscreen and if you turn the powerbook on and IMMEDIATELY close the lid, the computer should not return to the internal screen. It should stay focused on the external screen.

    The only thing is that I have to leave power applied to the screen all the time, but i have not experienced any problems with this as the ELO screen goes into a low-power mode when there is no signal.

    I can leave it like this for days at a time without problems.

    This is the behavior with my G4/500.

    The LCD should have it's own power supply so powering it should not be a problem.

    I like the CCar initiative, but it seems to have stalled. I still use iTunes and have written a touch controller in Revolution for it that does the job pretty well, albeit on the simplistic side. I will be happy to share it if you think you would like to use it as it makes it much easier to run iTunes from a small (or even a big) touchscreen

    How do you have the LCD connected so that it gets constant power?

    Edit:I know how the CCar Project isn't alive, but I do love the interface. It seems like the best out of all of the one's I have tested out. I will primary use this for music on short commutes and to play videos once in a while (which I could probably use conventional stuff like DVD Player or VLC/MPlayer.

    Edit 2: How should I wire all this stuff?

    The LCD has it's own power supply which is fed from a live battery feed as opposed to a switched circuit or a cig lighter power adapter.

    I've been using ccar occasionally, but hope it comes back.

    Wiring the stuff depends a lot on your car and your skill level.
