Re: Re: Issue with USB External Keyboard, External Mouse, and Screen Brightness on Dell Laptop
10,916 V looks a bit odd to me. After your comments, I looking forward about the battery voltage and I found this: https://www.linkedin.com/pulse/how-choose-laptop-battery-king-sener/ "Voltage is closely related to the number of cells in the battery - typically a 10.8V battery has 6 cells and a 14.4V battery has 8 cells." https://superuser.com/questions/33207/laptop-battery-is-voltage-really-important-to-respect https://superuser.com/a/406492 "The first stage is adapter which is nearly 5 V higher than the battery rating voltage to charge it faster to the full. Now the second stage is the motherboard or processor which typically runs at 5 V and for that you have voltage regulator inside." At 98%, the voltage here is: battery present: yes rechargeable:yes state: charging warning-level: none energy: 36,0417 Wh energy-empty:0 Wh energy-full: 36,3858 Wh energy-full-design: 59,94 Wh energy-rate: 1,8537 W voltage: 12,734 V charge-cycles: N/A time to full:11,1 minutes percentage: 99% capacity:60,7037% technology: lithium-ion icon-name: 'battery-full-charging-symbolic' I found that this battery I bought in 2019. However, it is pretty good yet! -- Marcelo

Is it possible that the USB ports do not supply power once the laptop is running on battery? Does the NumLock LED of the keyboard go out?

[ … ] > 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 advice would be to prepare for a day when you see nothing from the moment you switch it on. Here's a log of what happened with my Dell D430 laptop, purchased in 2008 as a stop-gap, acquired by me in 2009. First the battery packs: 2014-02-12 Large battery started to go bad. Charging light started constantly flashing a pattern: four yellows and a longer green. Apart from that, everything works ok: the battery stays at five lights, and the acpi variables all show sensible values. However, the battery discharges much more quickly than it should, particularly early on, so some cells probably don't work properly. 2015-03-29 Started to switch itself off when the power cable was disconnected. It appears that the battery is not actually connected to the computer when this happens. 2015-03-31 The large battery finally gave up. When the charge button is pressed, only LEDS 1, 3 and 5 light up, but flashing. Otherwise, dead. Disposed of the large battery in Best Buy's foyer and started using the small one. And the screen: 2011-10-21 Started to switch itself off unaccountably every so often. No freeze, no kernel panic, but just like holding down the power switch. It will have been running a while, and usually it happens when the machine or lid is moved. 2017-01-22 After a day or two of slight flickering in brightness, the screen blanked out a few times during the day. The machine was still running, and so X could be quit and restarted, and rebooted too. The screen would come back, but often disappear almost immediately, even while the Dell splash screen was being displayed at switch-on. It went away entirely the same day. 2018-06-19 After being depowered for a week, the battery capacity had fallen to 2%. However, on AC the screen started working again, though it just flickered a little all the time. Took the opportunity to demote Internal HDD to below USB and Optical Drive in the BIOS. Got about three minutes before it reverted. 2020-04-16 Started to crash, and eventually failed to boot. Obviously difficult to diagnose when there's no display at power-on, so scrapped. If you're wondering why I kept it so long, I could use an external monitor to display its X server screen, but neither the BIOS nor the console would work that way, so I had to type blind until I got into X. With a 30 second countdown, I could operate the Grub screen blind. I also managed to install buster in text mode by copying what I typed while installing on another PC at the same time. (I might have been able to clone jessie into the other partition, but that would have then required two dist-upgrades.) Cheers, David.

What does a dump show when the battery is fully charged? I wonder if that voltage is too low to support the laptop. My two ancient Lenovos (2011 and 2012) are both showing much better values than that. The difference between the energy-full and energy-full-design values, and the capacity both lead me to wonder if it isn't time to buy a new battery (or maybe a new or refurbished laptop). -- Does anybody read signatures any more? https://charlescurley.com https://charlescurley.com/blog/

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.

I still believe it is excessively aggressive power settings in GNOME or in firmware (BIOS) setup. Maybe it is result of shooting own foot by tools like powertop or tlp. Anyway it is rather wrong settings than wrong behavior. There is a chance that the issue is with USB controller driver. Likely it is better to ask the same question in a user group more specific to power management.

Re: Re: Issue with USB External Keyboard, External Mouse, and Screen Brightness on Dell Laptop
Dear Debian community, Thank you for your insights. Unfortunately, the issue has worsened. Today, I observed that upon unplugging the power cable, within one or two seconds, the screen dims (brightness is set to zero), and both the external mouse and keyboard (USB) stop working. Even if I try to use the keyboard or mouse, they do not reactivate. Only the laptop's internal touchpad and keyboard continue to function. When I reconnect the power cable, both the external mouse and keyboard resume working automatically. However, I need to manually adjust the screen brightness. I have not installed the usbguard package. Could there be another underlying cause? Best regards, -- Marcelo

A shot in the dark: does that happen only when running from battery? Perhaps the laptop is powering down its (internal) USB hub to save battery charge. In some BIOSes there are knobs to control this.
