The system cannot detect my battery (or AC adapter) since boot, and before a power event
like the following: (the acpi command provides no output)
$ acpiAfter I do one of the below
1. plug in AC adapter
2. remove AC adapter
3. cover my screen and uncover my screen
4. drain my battery to low power (probably 15% or 20%)
The system can detect my battery/AC
like the following:
$ acpi
Battery 0: Charging, 61%, 01:18:24 until charged$ acpi
Battery 0: Discharging, 61%, 05:17:15 remainingIs this a bug or solved issue?
or should I update my bios?
NOTE: This issue does not exist in Windows (8.1), on the same machine
The laptop is Dell Inspiron 14 7437, without touchscreen

I had this exact issue with my Inspiron 7537.
All I had to do was add the kernel parameter "acpi_osi=Linux" to grub. To do that, I added the URL to the wiki page to accomplish this and includes all boot loaders in case you don't know how.

It works! Thank you for your clear answer.

I'm glad I could help!
To complete the answer on whether it's a bug or not, it has to do with your BIOS expecting Windows rather than Linux. So you need to tell it that Linux is running and without the parameter, the kernel will return false if asked whether Linux is running. This causes some features to just simply not work.
If adding that parameter makes the screen's backlight to not work, you may want to add "acpi_backlight=vendor" to it also, but it actually caused my computer to not boot and seemed to not make a difference (probably should have mentioned that).
