Why does my laptop battery go flat when switched off

Why does my laptop battery go flat when switched off.
It only takes a day or so.
Any Ideas. I have tried to search the forums but cant find anything. I am shutting down not hibernating or going into low power mode.
I have changed the battery life option to close down when pressing the power button or selecting the correct shut down option
Any help appreciated.

Half an hour of searching and I have found this:-

My battery loses charge even when my VAIO is not switched on.

Solution:

This is normal, as the notebook (depending on the model) still needs to keep some parts on "standby" power even when the unit is switched off.
If you want to keep the battery full for a longer period, we recommend to take the battery out of the unit when not used.


What the hell have i bought. How can this be a good user experience I bought it to use away from my home not always with a power outlet handy any ideas or have I been conned by my trust of Sony as a brand?

Hi Ian1CovKid and welcome to Club Vaio.

Obviously the Vaio battery will discharge very slowly when switched off because power is always available to the Power Button to turn it on.

However, I would expect it to take two or three months to discharge the battery.

Please try two things for me as I do not have the problem and can only guess at a cause.

Firstly, fully charge the battery and remove it from the Vaio. After a day or so, reinsert it and see if it has discharged. If it has, then the battery needs replacing.

Secondly, check if the battery utility is the culprit. Before you close down, open Task Manager and kill the battery utility process (ISBMGR.EXE). Then close down normally and check for a discharge after a few days.

A second check of the Sony Battery Utility is to shut down, remove the battery for at least 30 seconds and reinsert. Check for discharge after a few days.

The suspicion I have is that the Sony Battery Utility does not shut down fully when the Vaio is shut down. Reinstalling the ISB Utility may be the way forward unless it is flawed.
