Battery found drained after shutting down.

Hello there,

I have a Dell Inspiron 3542 and for the past few weeks I have found that the battery drains after shutting down the laptop. The following is a step by step explanation of the issue :

1. After charging the laptop to 100 %, I clicked Start > Power > Shut down.

2. After waiting for like 5 minutes and ensuring that the laptop is, like "dead" ( no sounds, vibrations or anything ), I closed the lid and kept it on the table.

3. Next day, switch the laptop on and it does not turn on. The battery light flashes for a second and goes off. I connect the AC adapter and the laptop switches on. It shows 0 % battery.

I have run a full diagnostic check up of the laptop and the results do not display any issues related to memory, hard disk or the battery. Lid sensor also works perfectly.

However, I found something interesting. I checked the Event Viewer and I found the following logs :

1. Information 10-09-2017 21:16:51 User32 1074 None : 

The process Explorer.EXE has initiated the power off of computer DESKTOP-GJRG6VA on behalf of user DESKTOP-GJRG6VA\Dell Inspiron 3542 for the following reason: Other (Unplanned)
Reason Code: 0x0
Shut-down Type: power off

// That's when I shut down the laptop.

2.Information 10-09-2017 21:16:54 Winlogon 7002 (1102) : User Log-off Notification for Customer Experience Improvement Program

3. Information 10-09-2017 21:16:56 Kernel-Power 42 (64) : 

The system is entering sleep.

Sleep Reason: Application API

4. Information 10-09-2017 21:16:58 Kernel-Power 107 (102) : The system has resumed from sleep.

5. Information 11-09-2017 10:19:32 Kernel-General 1 (5) : 

The system time has changed to ‎2017‎-‎09‎-‎11T04:49:32.500000000Z from ‎2017‎-‎09‎-‎10T15:46:58.855067000Z.

Change Reason: System time synchronized with the hardware clock.

// That's the time I switched it back on.

As seen, the laptop was shut down on 10-09-2017 21:16:51. But, did it enter Sleep mode on 10-09-2017 21:16:56 ? and the log shows it resumed from sleep on 10-09-2017 21:16:58, but I did not see any response like the screen turning back on or something.

Does anyone has a solution to this issue ?
