Lenovo T430 Battery Life 1+ hour on life saver

Hi, I have had my T430 since August of 2012 at the start of college. I am currently running windows 8.1 pro and I recently just noticed my battery life issues and after installing lenovo settings I discovered that my battery's capacity is at 27% of the original capacity. The battery life is really bad, e.g. it says 15 minutes remaining at 25% on POWER SAVER mode.  I have google this and it said to "reset my battery" but unfortunately 8.1 Lenovo power manager doesn't have that feature.  I am just wondering if anyone had any suggestions for what to do?  Will I just have to get a new battery?

Re: Lenovo T430 Battery Life 1+ hour on life saver

you would have to have a pre-Windows 8 OS to gain that crucial battery reset function. This is one reason why i dislike running Win 8 on ThinkPad.

Hi,

 

Welcome to Lenovo Community Forums!

 

Capacity of a battery declines as the battery ages, with the number of charge cycles and time at high temperature. Under average usage patterns your battery maintains approximately 70% of its power capacity after the first year of operation.

 

If you feel that the battery backup is too low, try doing a battery firmware upgrade and BIOS update. Check the Lenovo support site for any battery firmware updates for your particular model. Most power is used by the display. Try to set up a power saving scheme with only necessary things powered on and lower the display brightness to improve the battery backup.

 

Refer this knowledgebase which explains some tips to improve battery backup.

 

I’m sorry to inform you that as of now, in Windows 8/8.1, there is no specific tool/software provided by Lenovo to perform a battery gauge reset. If you are running Windows XP, Vista and Windows 7, the battery reset procedure is pretty straight forward with the Think Vantage Power Manager installed.

 

In Windows 8/8.1, battery reset have to be performed manually. Battery reset can be done manually by fully charging the battery, fully discharging the battery and again fully recharging your battery. This will re-calibrate the battery.

 

Best regards,

Mithun.

I think you have both capacity and consumption rate issues.

Recalibrate your gauge first. If that doesn't work (battery is actually bad), then you'll need to replace it.

Then make sure your drivers are properly installed (especially NVIDIA Optimus if you have a late-model T410 with Optimus).
