I am having a Acer Aspire 4820T. I just installed Ubuntu 12.04. All is good but the battery shows as not present even though it is. And I don't have the power cable attached.

Have tried the commands in this post :

"Battery not present" on Toshiba Satellite L500D

But I get:

cat: /proc/acpi/battery/BAT1/state: No such file or directory

and

jim@ubuntu:/proc$ dmesg | grep battery
[    1.525162] ACPI: Battery Slot [BAT1] (battery present)

So it seems to know it is present, but the directory /proc/acpi/battery doesn't exist:

jim@ubuntu:/proc/acpi$ ls
button  event  wakeup

How can I fix this?

Ubuntu 12.14 doesn't exist. Did you mean 12.04 or 12.10? Please edit your question as this might be relevant. –  the_Seppi Dec 25 '13 at 21:55
    
12.04 - edited, sorry! –  user2987039 Dec 27 '13 at 20:07

Well, I have one too and it gives me a lot of issues(internet, screen...). What you can try is to just keep reinstalling ubuntu until it works.
