P52 - Error after updated BIOS v1.28, laptop battery charge not working !

Hi All,

 

I have P52 with BIOS version 1.18 are working fine.

 

After update to new BIOS version 1.28,  the memory speed had improved to 2666MHz (my laptop have 96GB 2666MHz), but my laptop battery charge are not working.

 

  • I plugged it into my laptop, fully charged 100% and then proceeded to update the BIOS.
  • After the BIOS update was successful, I have reset the BIOS to default setting.
  • In the Windows 10 interface, I lost the signal of the device charging, even though the device is still plugged in with Power mode: Battery 1 & 2.

Currently my device only has 80% of the remaining battery power, I shut down the device and do not know how to fix it.

 

Please help !

Hi bupbechanh,

 

I just thought of something: What does Lenovo Vantage say about the status of your battery? It's in Hardware settings>Power, at the top.

 

Also, check Airplane Power mode (turn it off, uncheck "Enable auto-detection") and Battery charge threshold.
