Battery drain while in sleep mode (Windows 10)

Hi,

I have windows 10 pro(with asus zenbook 14 pro ux480fd), and when closing the lead and entering sleep mode(I made sure of that in settings)

it drains the battery almost as if it wasn't on sleep mode. after contacting asus, they said it has to do with microsoft. 

are you aware of this issue? is there a working fix to this? 

just to compare, I have another laptop (6 years older) which can stay on sleep mode for a week. 

any help will be appreciated.

Looks like previous format wasn't liked , again this is from Battery Report

Hi Shivj

Please try this fix:

Open Device Manager (accessible by right clicking your Start Button)

Expand the Batteries section

For each device in that section:

Right click and choose Uninstall

Shut your laptop down

Disconnect the power adapter

If you can, remove the battery from your laptop

Press and hold the Power button on your laptop for 30 seconds

Re-insert the battery, if you removed it

Re-connect the power adapter

Turn on your laptop
