Battery drain while in sleep mode (Windows 10)

Why does my Asus Transformer book T100 battery drain drastically while in sleep mode?

Original Title/Subject: Battery

Hi All,

I have an asus notebook (UX501V).

When I put it in sleep mode, or just close it (not shut down), it drains fast.

My old windows 7 laptop could sleep for a week without loosing more than 1% battery.

Does anyone have a solution for this?

Thanks!

Hello,

Sorry but the answer is absolutely not helpful : 

In the answer, it is written that : "The issue could occur if there is**change in power management settings"

I can tell you that This is a brand new computer, and I didn't change any settings in power management.

Still.. the issue occurs.

I repeat (please read carefully): 

If I keep my laptop in sleep mode for a few hours, it drains my laptop battery, as if I where in wake mode.

In the answer I've been asked to provide the following information :

"What is the make and model of the Computer?"

It shows clearly that the person who answered didn't read my question!

I have stated that I own a Microsoft "Surface Pro 4" (Have you heard about this model?)

Sincerely,

I poked around online to try and see what solutions are out there.  I was able to run the powercfg/energy report in cmd prompt and got the report below.  The problem is that I am not technical enough to know how to resolve the errors found.   Does anyone know if there is step-by-step documentation out there to walk a relative lay person through these issues?
