    I have searched the forum and cannot find a reference to this problem....any help appreciated:
    1. SONY VAIO VGN-FE790G with Windows XP Home. Ran A-OK until recently.
    2. PC powers on and boots up normally with AC only. (battery removed)
    3. PC powers on boots up normally with charged battery only. (AC removed)
    4. PC will not power up with both AC and Battery connected, however battery led flashed rapidly as though it is charging.
    5. Have tried different battery, different AC, and removed all SONY management software.
    6. Updated the BIOS
    7. Windows Power Meter recognizes battery, but gives "remaining unavailable" status.

    I am assuming this is somehow related to the battery or the power management hardware in the PC. I understand there is a Power Board attached to the Motherboard. Could this be causing the symptoms I have?
