    hibernation tab missing

    Hi there,

    I've just pieced together my car pc and loaded up windows (for the 2nd time).

    First time round, I had the hibernate tab in the power options however the VGA output wouldnt work with the lilliput. Found out it was the ATI Video driver so reinstalled windows again, but this time with out the ATI Video Driver. My Lilliput works fine, however i seem to be missing the hibernate tab. I checked under device manager, under the "computer" heading it says 'ACPI Multiprocessor PC".

    Anyone know how to get this hibernate tab back? Its kind of a big issue, i dont want the car to turn on and off at every change in ignition status.

    Likely a driver issue...IIRC, the hibernate tab won't be enabled if even one connected device can't go into hibernation (because of a missing/uninstalled driver supporting hibernation, etc.). Check that each of the devices installed on your computer have updated drivers specific to that component. I'm not sure, but if you have a ATI graphics card and Windows installed a generic graphics driver, that driver might not support hibernation.

    Out of curiosity...why wouldn't the ATI video driver's output work with the Lilliput? Lilliputs take standard resolutions and refresh rates, and most any ATI driver/card should be able to output 640x480 or 800x600 without issue. Are you SURE it was the driver?

    were you trying with windows ati drivers, or the newest ones downloaded from ati? the stanby and hibernate options will be disabled if the vid drivers aren't installed.

    hi there,

    everytime i installed the ati drivers for the vga output the screen just said "no input signal" after all the bios/dos stuff loaded up. So i thought it best not install the ati driver and let windows use what it thinks is the most appropriate. However, this has lead to 2 problems

    1. Hibernation mode has disappeared, and david you are right, if the correct drivers are not available to the system for the graphics card it cant turn it off for hibernation.

    2. video's dont play properly, they have lines all over them.

    The ATI drivers do support the correct resolutions, 800 x 480 is ideal for the screen, i think there are some issues with the refresh rate set up on my carpc. Reading some of the threads around, it seems its best to use 75hz or less with a lilliput. I will try that later tonight when i get home and see if i have any success.... will post results up on both threads...

    Cool...sounds like you'll work it out. Interested to see the results.

    right,

    I would have thrown this all out my window if it hadn't cost me soo much!!!!

    the Motherboard I'm using is a Commell LV-681. Its an AMD based Motherboard. The graphics adaptor is an "ATI Radeon Xpress Series". This runs the VGA output on the back. Its the latest driver.

    In the "list all modes" section (display settings-->settings-->advanced-->adaptor) there is a list of resolutions, colour types and refresh rates.

    I have tried using 800 x 480 @ 60Hz, no luck
    800 x 600 @ 60Hz, 70Hz, 72Hz, 75Hz, no luck

    I have no idea what the problem, on the plus side, i got the hibernate tab back, lol, see how much use that is with a screen that refuses to work....

    anyone have any thoughts???

    Could it be a problem with the screen itself? I have no idea what refresh rates your screen should support, but all the rates you tried are certainly reasonable. Could you just replace the screen?

    You might also try using powerstrip, a utility that should allow you to have much more control over all aspects of your graphics card, and might enable some additional refresh rates/options.

    Cant change the screen, spent $700.00 on it, lol. The screen is fine because it works with my desktop pc without any problems at all the resolutions and refresh rates. I think i'm going to try a PCI graphics card, and disable the onboard one from the bios, see if that makes any difference.
