    Darter Ultra (daru2) wireless button.

    Hello,

    To all you guys that own a 'daru2' - When you press the wireless button, how many states do you have?

    I'll explain:
    Do you have:
    First Click - Wifi + Bluetooth ON.
    Second Click - Wifi + Blueooth OFF.

    *OR*

    First Click - Wifi On, Blutooth Off.
    Second Click - Wifi + Bluetooth On.
    Third Click - Wifi Off, Bluetooth On,
    Fourth Click - Wifi + Bluetooth OFF.

    You can test that from your laptop's boot screen, so you just test the laptop and don't have the effect of the OS.

    Please post your version of Ubuntu and Bios version.

    Thanks,
    Idan

    Re: Darter Ultra (daru2) wireless button.

    I have the MSI PR200.

    Using Ubuntu 7.10 and the latest Vista BIOS only gives me two options:
    BT and Wifi on
    BT and Wifi off

    I remember that when it was still running Vista (came pre-installed) I'd have four options:
    BT and Wifi on
    BT and Wifi off
    BT on and Wifi off
    BT off and Wifi on
    Plus there was an additional 'graphical utility' to manage which had to be on or off.

    Nevertheless, I feel that the two possibilities I have now, are more than enough.

    But aren't you wasting battery power with BT on ??

    Thanks,

    Yes, but I think (/me is no expert!) that the power consumption of the BT is rather minute.
    It's not like on a mobile phone where you have very limited battery time.

    I think I still get about 4 hours easily on a 9-cell battery with Ubuntu. Which is enough for me.
    With some more tinkering, I could probably bump that up a notch or two. But I'm too lazy...

    A friend of mine has the PR200 (it's like the daru2) and he runs Ubuntu with the 3.43 bios.

    He has 4 states with his wireless.

    I have only 2.

    What are the diffrences between 3.43 and 1.43 from your (PR200) experience ?
    If you enable AHCI on the 3.43 does it work exactly like 1.43 ?

    Thanks,

    Idan.

    Sorry m8,

    Can't really help you there, as I've never used the 3.43 BIOS (Win XP). So I can't really compare.

    I still keep the Vista recovery partition in case something goes horribly wrong (like when pigs fly etc.) so I honestly can't be bothered to switch to 3.43 just because of the BT switch.

    Re: Darter Ultra (daru2) wireless button.

    It's a bios update thing. It appears MSI decided that four states weren't necessary and disabled it in the latest bios. It's not broken, but there's nothing you can really do about it, save downgrade your bios.

    If you want to do that, I'd highly recommend getting a bios image from system76 rather than trying to get it from the OEM, because there are manufacturer and model number strings in the bios image that the system76 driver scripts tap into, and they won't work unless they match up. Even then, I'm not sure if they can support that course of action.

    Given that bluetooth consumes such a small amount of power, I wouldn't really worry about it.

    I was just wondering

    I'm not flashing yet...

    The funny thing is that I thought BT uses a lot of power.

    Let's say I'm using a BT mouse - wouldn't that "drain" the battery?

    Sure, but nowhere NEAR as much as wireless would, especially if it's idle. 802.11 uses way more power than bluetooth uses. That being said, the use case where you might want to use a bluetooth mouse or accessory and not have the wireless on is now gone, which is disappointing. It would be nice if MSI had made it a BIOS option to have a simple wireless button rather than removing the ability altogether.

    I'll look into it and see if there are any options (perhaps an alternate image or something). Worst comes to worst, I could probably patch an older BIOS image so that the DMI strings matched up, but that is, of course, a totally unsupportable, warrantee-voidable thing to do. You could also edit the sys76 drivers script and hard-code it to bypass reading from DMI and then just assume you're a DarU2 (they're in Python, after all).

    All of this is, of course, assuming that any update utility you might use would let you downgrade.
