laptop battery draining heavily when shutdown

[M Vishnu Nampoothiri]

Recently I replaced my Toshiba Laptop's battery. With the Brand-new , Toshiba battery in place (fully charged), when I shut down the laptop for 12 hours, the power drains by 25%!. What could be the solution?

I don't know. If it's brand-new and from Toshiba, and the old battery did not do that, contact support and ask them to replace it.

Probably your laptop requires a battery calibration. (Your laptop may not have seen the 'true' ends of the charge level of the battery newly installed.) To do it manually, please follow the instructions on this page

If you require tools for doing the same, I read that Toshiba has released its latest bios updates including these features. So kindly consider updating your laptop bios.

Here is another tool for the same purpose which claims to help calibrate the laptop battery.

Hope you could solve the problem.
