Computer Trouble (Again)
I just learned that now, when I unplug my laptop, it dies.
Even though it’s supposed to be mostly charged.
I didn’t know this was a type of problem that could happen.It’s probably not battery overuse because, until today, the battery could last for about 5 hours.
I was using the laptop, while charging it, for about three hours now (after having used it chargerless right before that).
Then I pulled the plug, because the battery was mostly full anyway, and it died.Then I tried turning it on chargerless and it wouldn’t responded. I started it up while plugged in, then unplugged it again, and it died again.
I tried this three more times with minor variations before concluding that, yes, it’s a problem.
So now I’m running it while it’s “”“charging”“”.This is an Acer Aspire running Ubuntu 14.04 LTS, which I bought in September 2015.
The battery is not easily removable, otherwise I’d remove it and put it back, since that works well for some other things.Does anyone know what I should do?
Ohhhhhhh…. thissssss…..
Lithium batteries are temperamental, and there are sometimes various controls to treat them in different ways such as “do not charge more than 80 percent, or discharge less than 20 percent, or whatever arbitrary limits you choose”.
This is most common on business style laptops but yours might have it too.
On Linux, the control of these may be broken or you might have set it accidentally. Do you have any battery buttons on your keyboard? I had this problem with the Dell they gave me at my old job which had an unlabelled button for “just don’t charge the battery ever” for some reason.
As far as actually solving your problem, I can’t help. It’s a rabbit hole. Possibly @thirqual may have ideas. But it’s a place to look.
(Oh, and this may not instantly recover if you boot with a linux thumb drive.)
try “acpi -b” in the terminal when the charger is in place; copypaste results below
>alison@alison-Aspire-ES1-511:~$ acpi -b
>Battery 0: Unknown, 76%…I am not sure what to do with this.
Okay, that is weird.
next: “dmesg | grep -i battery”
That “76%” is strange as I’d have expected it to be something like “0%” in the most simple possibility (not charging because of a software setting) but the “Unknown” is, well, an unknown.
>ailson@ailson-Aspire-ES1-511:~$ dmesg | grep -i battery
>[ 1.423993] [Firmware Bug]: battery: (dis)charge rate invalid.
>[ 1.424033] ACPI: Battery Slot [BAT1] (battery present)(Bold is from the original)
Did you have a software update at the time this change happened?

serinemolecule answered: The battery’s not easily removable but it is removable, just take a screwdriver to it. That’s a good first step. You’ll probably need to buy a new battery, though.

That sounds a lot like a bad battery or misconnected one.What is the laptop model number? I’ve never seen any that...
