x220 battery drain help

2012-02-03, 13:38 PM

HI everyone, i have Lenovo x220 with the following specs i7, 160 SSD, 8GB ram, IPS display and finally a 9 cell battery however i notice that when my laptop is turned off i lose about 15% - 20% of my battery charge which i believe is too much. I have set my power management plan to charge my battery once it reaches 30% and up to 90% max. I always update my software & i didn't make any significant changes to any of Lenovo’s installed software.



Is the battery drain that is suffer from especially when my laptop is off is considered normal? i appreciate your help

Go to Command Prompt, type

powercfg -devicequery wake_armed

If any devices are listed, they are semi-active when the computer is off. You can go to Device Manager, find the device, open it's properties, go to the Power Management tab, and uncheck the wake box.

Some hardware are still running when the system is turned off.

 

Enter in bios and try disabling all the features you do not need that requires power even when the computer is off, i.e.. Always on USB, Wake on LAN etc. After that, see what happens. On my x120e I loose only 1% of power overnight. 15% is too much.

 

Too, when the computer is off, try to listen carefully for any noise coming from the board... Just to make sure nothing is in short circuit... I hope not! :)
