I have Lenovo Z500 laptop and recently migrated from Win7, where I used Lenovo utility to make the battery charge up to 60% (it said it would prolong its lifetime).
But after installing Ubuntu the setting still applies and the battery won't charge over those 60% and I couldn't find a way to change it so that it would charge to the battery to full. Any help would be appreciated.

Following on from the suggestion posted by karim samir, I tried this with success, but with a slight alteration to get around some permission denied errors that I was getting following the commands.
I'm using a Lenovo Yoga 2 13, running Ubuntu 21.10. Battery was stuck at 59%. It's now charging perfectly to 100%.
The commands that I used were:
Check Battery Conservation Status:
cat /sys/bus/platform/drivers/ideapad_acpi/VPC2004:00/conservation_mode
Result: 0 = disabled, 1= enabledDisable Battery Conservation Mode:
sudo bash -c 'echo 0 > /sys/bus/platform/drivers/ideapad_acpi/VPC2004:00/conservation_mode'Enable Battery Conservation Mode:
sudo bash -c 'echo 1 > /sys/bus/platform/drivers/ideapad_acpi/VPC2004:00/conservation_mode'Basically, I've inserted [sudo bash -c] and wrapped ' and ' around Karim's commands.
to manage conservation mode from linux there is a gnome extension that does the monitoring and switching (like Lenovo vintage on windows)
there is a also a manual method
::::::::: Conservative mode commands ::::::::
from terminal
sudo suwrite password
reading the current status:
cat /sys/bus/platform/drivers/ideapad_acpi/VPC2004:00/conservation_modeenable Conservation mode:
echo 1 > /sys/bus/platform/drivers/ideapad_acpi/VPC2004:00/conservation_modedisable conservation mode:
echo 0 > /sys/bus/platform/drivers/ideapad_acpi/VPC2004:00/conservation_modelet's see if the battery has been tampered with. Install TLP tools.
sudo add-apt-repository ppa:linrunner/tlp
sudo apt-get update
sudo apt-get install tlp tlp-rdwAnd then run:
sudo tlp startTo start the service and then
sudo tlp statto get the specifics of the battery.
Provide us with the output of that, specifically the CAPACITY parameter at the end.
1For Dell, it's available in the BIOS. There is Primary Charge configuration where I get to choose at what percentage, the battery starts and stops charging. And that would promptly apply across all Operating Systems on the PC.
I believe there must be something equivalent in your BIOS as well and the Windows utility should have changed that by directly writing into this setting. So patiently look into all the options in your BIOS and find this setting.
