Windows 10 windows scheduler fails when laptop is on batteries

hello everyone,
I'm new to this forum - hope we will have a nice time

I'm trying for weeks now to schedule a task to run a jar file every day at 3:20 pm.
the trick is - I want it to work when my laptop is in "sleep" (not "sleep mode").

The best I got was that the jar was succesfully activated on time and when the laptop was on "sleep" , but the scheduler only made it when it was on AC power and never on batteries.

here is ALL I did:

1) setting "allow wake timers" to "Enable" in "Sleep" option on my power settings.
2) created a new task with the following check-box's marked V:

general:
run whether user is logged on or not.
run with highest privileges.

conditions:
wake the computer to run this task

Settings:
allow task to run on demand
stop the task if it runs longer than 3 days
if the running task does not end when requested force it to stop

my trigger is on schedule (as i said above)

my action is :

run a proggram,

proggram/script: C:\ProgramData\Oracle\Java\javapath\java.exe

add arguments: -jar C:\Users\Owner\Desktop\Print.jar
start at: C:\Users\Owner\Desktop

any advice on what may cause it to only run on AC power will be appreciated.
