Lenovo IdeaPad G50-80 Ubuntu battery not charging above 59%

[anuj agarwal]

Hi All,

I recently bought this laptop and it came with a pre installed DOS. I formatted it and installed Ubuntu in it and then came to know that Lenovo laptop has this feature to save battery life. I searched a lot on Google and tried several methods (like removing the battery and keep the power button pressed for 15-20 seconds) there but none seems to work. I don't want to install Windows for this.

If any of you faced similar problem and found a solution without Windows. Please help me out.

Thanks,
Anuj

Anuj,

It seems this is a "feature" of the Lenovo battery charging firmware: to extend the life of the battery, it does not charge above 60%. What's your battery life like when you unplug the AC? I don't think this is a Linux issue, but it's a good thing to know about.

Thanks Jeremiah for reply. I know this is a feature and not related to Ubuntu. But I am interested in changing these settings while in Linux.

[anuj agarwal]

My battery life after unplugging is decent so that is not a problem but sometimes I travel and want to use more battery life.

[Jeremiah Bess]

I gotcha. I am unaware of a method to change that.

[anuj agarwal]

Thanks anyway.

Your battery maybe out of sync with your laptop. Try the following to see if you can get back in sync

Remove both the battery and power adapter from the laptop.

Hold the power button down on the laptop for 45 ton 60 seconds to drain residual power in the system

Put the battery back in and run the laptop until it does a low power shutdown, try to delay that as long as possible.

Put the power adapter plug back in and keep the computer on (don't let it sleep or hibernate as well.) You can use the inhibite sleep applet in MATE or Caffeine in other Desktops to facilitate that.

Let the battery charge to full power and then restart to get the battery and systems firmware in sync.

It isn't about it being free. Rather, its about the freedom it brings.

I tried what you suggested but with no luck. The laptop still stuck at 59%.

[Shaun Marolf]

You may want to replace the battery soon.

Finally I installed windows in another partition and turned off that setting. It's working fine now.

[Jeremiah Bess]

Sorry we weren't much help with a Linux solution. What was the name of the setting in Windows, and where do you go to turn it off? This might help others with the same issue.

[anuj agarwal]

There is a Lenovo energy management software. Change setting from optimize battery life to maximum battery life.

[Jeremiah Bess]

Thanks. If you don't mind, now that I know the name of the setting, I was able to dig up a few more articles. Please let me know if any of these were helpful.

I also found these while I was searching. But these only apply to Thinkpad. I have an Ideapad which does not support these features.

Ideapad != Ideal for Linux.
