Flex 3-1480 battery discharges even when totally off/shutdown (NOT sleep mode)

I have a Flex 3 that is only 4 months old and notice that even when the laptop is totally off (powered down, no lights on, not hibernate or sleep) after a day or two the batter charge upon bootup has gone down significantly.

 

I am talking a reduction of say 40%.

 

I am under warranty and I have to run this "Battery gauge reset" routine and do a few other checks before they replace the battery.  Although I can't imagine how looking at windows power options can impact what the battery draw is while the unit is OFF and windows is not running....but guess they have to go through their script.

 

Anyway my question is on this Battery Gauge reset.  I have read things where this takes all night or something and people have to turn sleep mode off on their laptop? That is not in the official instructions so for those that have had this issue or run the reset do you just "press the button" or do I need to make sure the laptop stays awake.

Also, what is it actually doing??

 

Is this type of battery drain a known issue?  To me it sure seems like just a bad battery....

Thanks,

Hi BJBBJB,

 

Yes it is just a press the button and let it run. It should not take longer than about 30 mins to complete.

 

Its not a known issue but it does happen from time to time and i agree you may have a faulty battery but the troubleshooting steps need to be followed as they sometimes do fix the issue.

 

Hope this help you and let us know how you get on
