I have a Lenovo y400. Whenever I unplug the laptop, the battery meter shows 0:06 or less and the Laptop battery critically low message pops up. It hibernates once in a while, the rest of the time it increases gradually and shows the correct time after about a minute. How can I fix this?


Maybe you can try a power saving app like TLP. I've been using it since some days and it has been really efficient for my battery usage.

You can find a great configuration help for that here:
Is there a power saving application similar to Jupiter?

  • My problem isn't battery usage. It's that the amount of charge/time left on battery is read wrong initially, hence the hibernating. – topher Feb 9 '14 at 9:50
