L340 Problem with Battery

2021-09-06, 16:42 PM

Hope this message finds you well,

I have Lenovo L340 gaming laptop about a year ago. The worked very well with average range of 6-8 hours till I did the bios update that was made by Lenovo system update official website. The battery became very weak and with average 1-2 hours. Could anyone quickly tell me how to fix this problem? And how to do a flashback to the old bios if this one will not be updated to fix this problem? 

Thanks in advance.

The only way to do a bios back flash is to ENABLE it before you do a bios update.

 

 

As far as saving power, I would go through the bios bit by bit and see what can be turned off, if you are not sure what does what then please ask again for clarification.

It would also help if you post your  system machine type and model (MTM) and bios version but not your serial number.

Hello @Jermiah ,

 

Welcome to the Community Forums.

 

To add to teccky's suggestion you could  try loading the default BIOS settings to see if that fixes the issues.

 

BIOS reset

- Press the power button to completely shut down the unit.

- Press the F1 repeatedly on startup to enter BIOS.

- Navigate to the "Restart" tab

- Press "Load Default Settings"

- Save & Exit changes or F10. Some instructions on how to open the BIOS: https://support.lenovo.com/us/en/solutions/ht500216-recommended-way-to-enter-bios-ideapad


Hope this helps.
Regards,
Jack_Lenovo1
