    Hi,

    I've a problem with my Z930-164 : The battery loose around 8% every 12 hours while it is off.

    I've the latest bios (6.80) and the latests drivers. I'm with windows 7 64 bits.

    By trying many things, I've founded that it is the option : "Sleep and Charge" in the bios. By default it is on Auto mode (1.5 A), there is a 2.0A mode too. If I turn it off, the battery only loose 1% every 12 hours while it is off.

    In default mode, why it does not power the USB while sleeping ONLY if there is a device ? Not to drain the battery !

    It is a huge problem no ?

    null

    The enabled Sleep & Charge function affects the battery working time.
    Sleep & Charge allows to charge external connected devices (like smartphone) even if the notebook is in sleep mode.

    Furthermore enabled “Wakeup” options (Wake up on LAN, etc..) which are available in BIOS would lead to battery discharging.
    Therefore disable these options if you don’t want to discharge the battery.
