Battery discharge whilst laptop is in shutdown

2021-04-28, 7:44 AM

Hi,

 

I have had two Lenovo ThinkBook 15 G2 ITL 20VE005AUK laptops and both have the same problem (I sent the first one back to the supplier due to this problem, but the 2nd machine is now doing the same).

 

The battery appears to discharge when the laptop is powered off (I have disabled wake on lan, disabled USB charging when off and disabled fast start up) - I only use the laptop through AC power and use the conservation mode. 

I have run the Battery Report and this shows no battery usage or activity (which I would expect, as I only use AC to power the laptop).

Vantage shows the battery as being in good condition and the battery has its full charge capacity.

 

If I leave the laptop shutdown and turned off for a day or two, the battery discharges by a few percent; however, the longer I leave the laptop turned off, the more the battery drops. For example, I turned off the laptop at 4:30pm last Friday and didn't turn it back on until 6:00pm yesterday (Tuesday) and the battery had dropped from 94% down to 62% despite not being used at all.

 

Why is the battery discharging when not in use?

Hi simontakel,

 

Welcome to the Community Forums.

 

Do you have any external devices connected to the laptop when it's turned off ? If so, then it could be because of the "Always On USB" or "Charge In Battery Mode" function in the BIOS.

 

 

BIOS Load Default Settings.
- Press the power button to completely shut down the unit.
- Press the F1 repeatedly on startup to enter BIOS.
- Navigate to the "Configuration" tab
- Set "Always On USB" & "Charge in Battery Mode" to 'Disabled'
- Go to the "Exit" tab, and click "Exit Saving Changes"  or Press "F10".

 

 

Hope this helps

 

Regards


Voithos

Hi @Voithos, thanks for the message but I don't have any devices attached and I have turned those setting off previously anyway.

Can you try manually installing the BIOS, Power management driver, and GPU driver from here: https://pcsupport.lenovo.com/us/en/products/laptops-and-netbooks/thinkbook-series/thinkbook-15-g2-itl/20ve/20ve005auk/downloads/driver-list/

 


Let us know how it goes.

Hi @Jwes_Lenovo - BIOS is already the up-to-date version and after running some update scans, Vantage and Service Bridge both say there are not any other updates needed.

Why would I need to do that though when all the drivers and updates are showing as updated?

I have the same isse with ThinkBook 14s ITL!

 

I have also bought two, boths have the same issue!

Updated the BIOS, nothing changed, disabled the USB Charging in BIOS, disabled the FastBoot in Windows 10, but did not get better, the battery drains after a full/real shoutdown.

If I disconnect the battery in the BIOS "for service", the battery does not drain at all, so the batteries have no problem, but if I want to use the laptop again, I have to connect it to the carger for a second, however the battery is fully charged and it is not good for the battery.

Beacause the laptop drains in powered off state there is no reason to check/update Windows drivers! Why if the Windows is not even running in this case???

Can someone from Lenovo please investigate this problem? There are multiple people reporting the same issue.

Is there a BIOS update planned to correct this?

Same problem here.

 

I bought a thinkpad 14ITL, still in warranty. 

In the evening I turn it off at 70%, in the morning it's less than 2%, with no usage at all.
