I have a Lenovo 3000 N100 and my battery gets low real fast (sorry for bad English)
i read somewhere to execute
cat /proc/acpi/battery/BAT1/info and check out design and last full capacity if they match that it is good if they don't my battery is properly dead/broken
well as you can see they match
present: yes design capacity: 4800 mAh last full capacity: 4800 mAh battery technology: rechargeable design voltage: 11100 mV design capacity warning: 420 mAh design capacity low: 156 mAh cycle count: 0 capacity granularity 1: 264 mAh capacity granularity 2: 3780 mAh model number: PABAS024 serial number: 3658Q battery type: LION OEM info: SAMSUNG
After that I did some googling and thought I found a fix. I added
/etc/default/grub. I fully charged the battery but still when I take out the adapter I immediately get message box that says
battery critically low. Then when it gets in sleep mode and i connect my adapter again and wakes up from hibernation my screen is all white and black.
I found in Askubuntu that you should put
aspm=force in this line
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pcie_aspm=force" and not in a seperate line
when i did that immediatly to 2 min then to 27 min then 24 min then 15/22/19/11/12/8/5/1
43 min battery, but hibernation still crashes
How do I solve this?
