W530 battery life¶
After about a year of usage maximal charge of my battery dropped about 40%, which is way too much. On Windows there are some settings that “enhance battery lifespan”.
It seems that to enhance lifespan of your batteries you’ll need to:
- Charge it for longer periods (ideally allways to full charge)
- Don’t charge it to 100%, set full charge to 90-something%
There are no generic tools to configure such behaviour — as it all sits inside BIOS. This question on ubuntu SO helped me to find solution, but nevertheless it didnt work on my W530 laptop.
After instal you’ll need to insert following into /etc/rclocal.d (it will be called after startup):
tpacpi-bat -s ST 0 80 tpacpi-bat -s SP 0 90
It will do the following: battery will stop chaging after charging to
of current maximal charge) and battery will start charging only after it is
80% (which will cause that you will charge it for 10% capacity
It would be great it I could (for example) inhibit charging for (let’s say) 15 minutes after connectiong to AC, as I often connect the computer and then decide I need to go somewhere else, which is not healthy for battery.
