Windows 10: Laptop drains full battery in sleep mode during the night

This is really putting me at my wits end! I'm not sure what's going on... I've checked the battery and it's functioning normally even took it to a local computer shop he said it's not the battery most likely. I disabled all the apps that can run in the background or come on during sleep... I'm confused what my issue is. The laptop is a dell inspiron 15 running windows 10. When I wake up in the morning to use it I press the power button and it just makes the noise as if it's turning itself off which it does I plug it in and it starts up fine... with 2% battery. I tried hibernation mode last night and still did the same thing so I'm desperate for a fix if anyone can help me solve this issue I'd appreciate it.

Battery drains while on sleep mode.


Sleep Mode has never been efficient. In all my years of using laptops, I've always just turned them off and on. Battery drain is normal for sleep mode. Some people have had issues with the laptops not powering off completely and draining the battery, but if that's your issue, there is an easy fix. You turn off Fast Startup and check a setting in Device Management under Intel Management Engine.

even mine has a slow battery drain, using Win 8.1. Even when powered off, not in sleep or hibernate, but off. It still uses the battery to keep the clock going.
Turn off fast start, as suggested, hibernate over sleep as it uses less power, and if you aren't going to use it for several hours, shut it off.

 

Battery drain in sleep mode

Hi,

I have an Asus UX430U and it's draining the battery when in sleep mode.

The cpu is running when in sleep mode. I suppose it should not happen.

The laptop is getting really hot and the whole battery goes off in around 1 hour in sleep mode.

Thanks to anyone who could help.
