X260 battery drained to 5% during sleeping overnight

I have received my new X260 laptop a month ago (also my first Lenovo), I did a fresh install of Windows 10 Pro and a bunch of drivers. It has been working well until now.

 

Two days ago, I used it all-day with original adaptor plugged in. At the end of the day, I unplugged it and close the lid to put it to Sleep mode before I left work. The day after, I came to work and found my X260 battery was at 5%. I thought I have mistakenly set the Power Option so I checked and it was set to Sleep when I close the lid.

 

Yesterday, I did the same, put it to Sleep before leaving work, but this time I clicked Start > Power icon > Sleep to make sure it entered Sleep mode and I watched the red LED on the lid blink slowly.

 

Today I came to work and the battery was at 5% again!

 

I am suspecting that X260 woke up at some point during the night. I don't know how, no cables connected.

 

Please guide me if I need to update any driver or check any settings on Windows/BIOS.

 

Thank you.

Look through Event Viewer -> Windows Logs -> System to determine whether the system is unexpectedly coming out of sleep mode.  If so, see if there are any clues about why this is happening.
