I have a little but annoying problem with my laptop. For quite some time my Asus K53SD (Xubuntu last LTS) 64 bits is shutting down without any demand when it have about 50% battery. I checked the power parameters (which I didn't touch) even if I see nothing wrong:

Perhaps, the system overvalue the real capacity of my battery?

Note: When I reboot my computer it shuts down immediately.

My battery is 'dead' (60 % dammage) according to Windows (CMD):

powercfg -energy

  • Seems awfully like a dead battery. How old it is? I had exactly the same problem with a Toshiba laptop 2 years ago, and had to buy a new battery. – Rmano Nov 04 '14 at 15:54
  • I bought it in 2013, almost two years ago. What is difficult for me to understand is that two weeks ago, I had not this problem. – Yilmaz Khan Nov 04 '14 at 20:37

Could be a few issues. The battery itself could have an issue or defect in it, depending on how old the battery is. I had a laptop I had when I was a lot younger that I always left plugged in and destroyed my battery so it couldn't hold a charge.

Also, how hot does your laptop get? Laptops typically shut themselves down to prevent damage if they get too warm. Take a look at your logs, usually there will be some kind of warning in syslog to hardware issues.

  • I don't think I have thermal problems but you know better :

    acpitz-virtual-0 Adapter: Virtual device temp1: +58.0°C (crit = +103.0°C)

    coretemp-isa-0000 Adapter: ISA adapter Physical id 0: +60.0°C (high = +86.0°C, crit = +100.0°C) Core 0: +60.0°C (high = +86.0°C, crit = +100.0°C) Core 1: +58.0°C (high = +86.0°C, crit = +100.0°C)

  • The numbers don't look unusual... but the point I was getting at is that if you don't typically let your battery drain completely, you end up damaging the battery keeping it from holding a charge. This is known as "solidifying your battery", which would explain why your battery dies at 60%. Also, take a peek in /var/log/syslog and see if there is any mention of warnings. Syslog cat's everything the system does. – Miliardo Nov 09 '14 at 19:33
