In case some of you aren't on the device owners list I posted this to before, I created a script that will detect when you're plugged into a charger that's causing a slow (100mA) charge and will ask if you want to do fast charge instead.
Examples of such chargers include a car charger, the usb port on a Windows computer without the Neo inf installed, etc. -------------------- I created a script to monitor for slow charge and pop up a gui asking if you want to switch to fast charge mode. The default instructions install the script and an init.d script to start & stop it, as well as links to make the daemon start automatically. The page telling how to install is http://wiki.openmoko.org/wiki/CheckFastCharge-script >From the page: What it does Your neo will detect when it is charging slowly and pop up a gui to ask if you want to switch to fast charge mode. It will take a few seconds to detect that you are charging slowly. Details checkFastCharge will remember if you select slow charge and not ask you again. If you accidentally selected slow charge, unplug the neo from the charger for several seconds, then plug it back in. Next time the script checks, it will ask again if you want slow or fast charge. When you select fast charge, the script goes through a confirmation sequence, because fast charge can be dangerous for your hardware if the charger doesn't support 500 mA or more. Just click 'Confirm' four times to confirm that you want to go into fast charge mode. Let me know if you see obvious improvements, or if you want to make an ipkg of it (I will eventually do so myself...), or if you know a better place for me to host the download. Bobby > Am Do 28.
