Lenovo Z50-70 battery life runs quicky than it should

Hi everyone! I'm new here, so I'll try to do my best. I bought a Lenovo z50-70 two days ago and I found a problem with the battery. The thing is that it's life runs out pretty fast... it said that I have 3:21 hours remaining and two minutes later, just 2:40. It's like it dicreases 1% every two minutes. I don't know if it's a battery problem or something else. Someone has some ideas? Thank you in advance!

Hi Lulimares ,

 

 

Welcome to the Community Forums. 

 

Would the pc shut down if you allowed it to drain out on the percentage without connecting to a charger?

 

Step 1 . Power Drain . Remove the battery and unplug the charger . Press and hold down the power button to drain for 15 seconds.

 

Step 2. Set BIOS defaults by placing back the battery and charger and use the Novo button (page 9 ) to start . Press on F9 to load defaults F10 to save and exit.

 

Step 3. Uninstall Microsoft acpi-compliant control method battery from the device manager and restart . 

 

Step 4. Manual Battery Calibration.

Allow battery to normally drain off until pc would shut down , Charge battery until 100 % and observe if battery still would be fast draining. Take note of the battery status LED indicators (page 14) . 

 

Step 5. Updating BIOS from support site.  ( BIOS upgrade may pose risk of bricking if guidelines not followed as described on read me file ) .  You may call in Lenovo Tech Support for the version compatible for your pc and have assisted if needed. Likewise , they can provide you options for repair once the battery is checked as point of failure.

There might be a need to recalibrate your battery meter. The recalibration process is different from the old computer batteries since the modern computer uses lithium ion batteries which do not have memories unlike in the old one. Here is a video that details suggested steps to recalibrate your battery meter.

Hi Lulimares , 

 

Greetings. 

 

Not fully charging to 100% and not draining it to 0% can extend battery life but  Li Batteries may be calibrated every 2-3 months for refreshing the checmicals within . 

This is what I also do with my mobile phones li battery too. 

 

Good to know that it's better now. 

 

Feel free to visit our community at anytime. 

 

Goodluck to all your endeavors. 

 

 

Cheers

Hi bips007 , 

 

 

Welcome to the Community Forums. 

 

Have you guys tried the steps indicated above with the tech guys? 

 

As you may have noticed , it isn't always the battery or the model that can cause it since even the firmware can be controlled by softwares too. 

 

The tech team would definitely be able to isolate it and if on their conclusion that the battery is the issue , most likely they would provide the service to fix it . 

 

See if the steps work for you else call in tech support for the service as needed. 

 

 

Regards
