THE PROBLEM: When I connect the AC Power Adapter, the battery icon shows a charging symbol but the percentage is always stuck in that percentage. e.g. 5:33 until full (30%) which is a lot to reach 100%. This changes every time I plug and unplug: 12 hours remaining, 6 hours to full, 11 hours, and so on. Definitely, the OS is making bad predictions. The battery discharges normally in 3 hours of usage (normal behavior) but never charges when I plug it on. Also, even if I keep for 1 hour the charger connected, then disconnect it and then restart the laptop, the battery will still be in that % but now will discharge. This shows a healthy battery. I ran a health check and it's 88% of capacity, which means it can still store energy (it is a new device, I mean..).My battery went 0% two times so far and I was able to make it charge from there by: Turning off the laptop. Connect the AC power adapter (since the battery reached 0% and cannot turn it on without the adapter). Hold the power button for 30 seconds to perform an RTC BIOS reset. (After this the orange LED blinks 2 times indicating a successful reset). Accept the warning message about the successful reset. When Ubuntu is loaded, after signing in I unplug the AC power, so the laptop turns off. When I connect the adapter again, the white LED indicator turns on immediately meaning that the battery is being charged. After 2-3 hours of charging I disconnect and turn on the laptop without the adapter but with 100% of battery. THINGS TO KNOW: - Note 1: Every time I connect the AC Adapter, and the battery has more than 0%, this white LED indicator turns on only for 5 seconds and turns off immediately. This is kind of weird since this normally happens when the battery reaches 100% meaning that it does not need to charge anymore. - Note 2: I tried disconnecting the battery from the motherboard and performing a power reset holding for 15 - 20 seconds the power button, just like explained on the dell webpage, and then connecting everything back but nothing. I left the laptop battery disconnected for 24 hs and still nothing. - Device: Dell Inspiron 3515 bought in August 2022. - Hardware update: This version came with 8 GB of ram, so I upgraded it to 16 GB adding a SODIMM 8 GB ram. (October 2022). - Operating System: I installed Ubuntu 20.04 LTS and I'm constantly adding updates that Ubuntu offers me related to security and performance. - Bugs: - My touchpad for some reason sometimes gets sucked when I use the "double touch" gesture to scroll. (Drivers incompatibility indicators from the OS) I found this issue and it's an OS bug that has been reported already. - Sometimes when I open the laptop, the screen holds a video bug of RGB pixels but is distorted for 1 second, and then it shows the image. (Another indicator) - BIOS VERSION: 1.2.0 - Info in BIOS: AC Power adapter: <65W> (it is detected) - Dell Support Assist diagnosis: All looking great. No issues were found. Battery healthy and AC power detected successfully.   POSSIBLE SOLUTIONS THAT I CAN IMAGINE: - BIOS update? - Go back to the out-of-box windows 11? - Try another version of Linux? Is this a battery "charge cycle driver" problem or something similar? - I would like to receive warranty solutions. Thanks a lot for the support and I hope to get help.
