Dear Debian Users,
Thank you all for the invaluable assistance provided. Unfortunately, the issue
has resurfaced today. I don't believe it's related to the age of the hardware,
although my Inspiron 5547-A20 is from 2014, as indicated below:
Inspiron 5547 01 OCT. 2014
Some hardware details:
- BIOS:
- Vendor: Dell Inc.
- Version: A13
- Date: 05/27/2019
- CPU:
- Product: Intel(R) Core(TM) i7-4510U CPU @ 2.00GHz
- Memory:
- Size: 16GB
Today, the battery still had 66% charge when this strange problem occurred.
It's worth mentioning that in all these days, between my last post here on the
list and today, I always use the battery until it reaches between 20-10%, at
which point I plug in the charger and let it charge until it reaches 95-100%.
I ran the following commands:
With the power cable plugged into the power grid, i.e., the battery is charging:
:~$ sudo lsusb -t

usb3
:~$
After unplugging the power cable, i.e., the battery is discharging:
After a few seconds, the screen brightness is set to zero. The mouse remains
active, and I can use it for a few more seconds, when it also becomes disabled.
From then on, only the touchpad and internal keyboard are functional.

Any other suggestions? It seems to me that it's not related to power, however,
what is the specific list for energy-related issues?
My first post on the list is at:

Thank you very much.
