Satellite Z830-10J Battery discharges when system is shut down
Posted: 24-Feb-2012 20:38

My new Toshiba Satellite Z830 10J ultrabook with Win7 64bit,. all updates, works fine and shows no deficiencies, there is however one strange exception.

When the battery is fully charded and i "pull the plug", the system runs on the battery for sometimes more than 5 hours, so i assume the battery cycle is ok.

When the battery now is fully charged again and i SHUT DOWN the system and do not use it for a few days,
then the battery is totally DISCHARGED to 0% and the system will not boot, until i plug it in.

This phenomenon occurs in less than a week. So: charging the batrery to 100%, switching off the system, pulling the plug, wanting to re-use the system after 7 days, yields to 0% battery charge.

Is there any specific reason for this?

greetings

Hello Roland

It is well known that battery looses capacity over night or after few days but maybe several percent or maximal 20% but it is not known to me that battery will be complexly empty.

Is some external device connected to USB ports when the notebook is off or notebook is placed on the desk without any connected devices?

Please enter also BIOS settings and disable every option that can be related to this issue. I don’t have this new notebook and BIOS is not known to me but check please all BIOS settings. Disable wake =up on LAN or USB sleep and charge.

I went through BIOS - WOL was only enabled when on AC power but for the time being i desabled it totally and i also disabled the "wake on magic packet" feature in the network adapter (though this works fine and i did already use it in my LAN but i disabled it for now). Sleep-and-charge was on AUTO and i disabled it.

The ultrabook was in a case and no device at all connected. Battery lost about 15% in 24 hours.
Now i will see if those BIOS settings did have an effect and i will let you know.

It appears that one of the BIOS settings (either the disabling of sleep_and_charge or the disabling of WOL) solved the problem and the battery did not loose any significant charge in the last day.
