Battery not charging anymore (Dell Inspiron 7405 2n1)

English Applications
1

Hi, today while my laptop was plugged in, I saw that the battery icon popped up intermittently with the indicator showing that even though the battery was charging the percentage would decrease. Then the indicator completely disappeared so I tried to unplug the charger and then the computer powered off. Now the battery is stuck at 3% with the charger plugged in. I’m using a Dell Inspiron 7405 2n1.
Here are the output of upower -d

Hardware fault?

Can you post the output of

$ sudo dmidecode -t 22

And while you are at it, find your battery with

$ upower --enumerate

And then

$ upower -i <path to  battery>

This should provide some health stats for your battery.

I’m fairly confident this is not a TW issue (remote chance maybe).

Something I’d do is check for physical deformation like bulging of the battery - even a tiny bulge can be bad news.

I’d also check battery health using built-in diagnostic tools like Dell’s SupportAssist or via the BIOS.

Also, when the laptop is OFF (powered down), remove the battery, and plug the A/C power cord into the laptop … or dock the laptop into the A/C docking station.

Now power up and test. Same erratic issue, or no power up at all? Might be power cord, or receptacle at laptop., or laptop has internal hardware issues.

Might post to a Dell forum.

Try booting into the BIOS or UEFI (ie, before booting an OS). Plug laptop in. Does it charge?

If it doesn’t, then it’s a hardware issue. I’d also check for problems with the battery itself - physical deformation could certainly be an indicator of a problem.

Here is it. Getting an error for the 3rd one, not sure why.

Pleae use pre-formatted text ( </> ) for output

Easy … the command is expecting a [file] path to the battery.

A path does not begin with a ‘<’ character and does not end with a ‘>’ character.

Should be

#  upower -i /org/freedesktop/UPower/devices/battery_BAT0

Thanks, I left my computer off the entire night and this morning, the battery was fully charged but the battery health info in the bios was not available. Here is the output:

Sorry, I thought Blockquote was the way to do it, I will use preformated text going forward.

Then I connected my ebook reader to charge it and transfer some books (that was probably not the smartest idea). Then the battery started to lower, I disconnected the ebook reader, the battery started to recharge and then all of a sudden, it got disconnected and I had a critical alert saying that the system was going to hibernate because the battery is at 0%. Now it alternate between showing 95% battery icon indicator and system message saying “battery critical (0% remaining) the system will hybernate in 60 seconds”.

13

Looking at this, I’d suspect a hardware issue. Seen something alike in the past, replacing the battery solved it all.

14

Constantly plugging in to charge, at this point, (to me) is fruitless and is obviously not a solution.

Possibly missed a previous post of mine about troubleshooting this as a hardware issue. And it sure seems a high possibility at this point.

15

yes I will call a technician next week, I will probably have to replace the battery.

Just from the dmidecode output, I would say there is something wrong with the battery. For comparison, here is my output:

Dell’s support site has a section on battery troubleshooting. There may be something there that can help you.
