Dell Inspiron 15 7537 - Problems AFTER Win 10 installed --- Battery draining to 0% After Shutdown and Computer does not wake up from Sleep

My laptop's battery was working perfectly with 8.1 and laptop was turning on after I put it to SLEEP.

After upgrade to Win 10, I started to encounter problems with battery drain and my laptop would not wake up after SLEEP.  I would have to HOLD the POWER button down and the computer would RESTART.

After charging my computer fully I would SHUT DOWN, and then 8 hours later the computer would not turn on (battery at 0% or 1%).

When I would put the laptop to sleep, my laptop would not wake up after clicking the power button.  I would need to hold the power button for the computer to RESTART.

I have seen suggestions from the community but I really would like to receive a response from a DELL representative so that I do not make any mistakes.

Please let me know what should be done to fix this problem which forces me to carry my power cord with me everywhere.
