Question L390 wont boot when charger is connected. Remove charger and boots straight away.

[JohnDoer]

Hello.

I have Lenovo Thinkpad L390. When i restart OS the laptop shuts down but wont restart. Machine is on but screen is black. When i remove the charger, it boots right away and works like a charm. No error's are given when i connect the charger.

Edit: i have already opened the laptop and discharged bios battery, no help.
Edit2: when it shutsdown and wont start, theres a led in FN Lock and F1 keys.
Edit3: If i shutdown the machine and then push power button it starts normally. So this only occurs on restart

Did a different charger get you the same issue?

edit:
reinstall all drivers from the Lenovo homepage

eventually factory reset the laptop

Other than that, replace the battery

Actually did all these already. I also replaced the battery from another machine working fine and got same results. So its not the battery.

Have also tried with Windows 10 and Kali

Update the BIOS if available

Update the BIOS if available

This was already done by lenovo system update couple of weeks ago. Had my hopes up with that but it was a no go...

Which BIOS version is the BIOS currently showing ? Sometimes not the latest version will be updated by the system updater.

Did you download the drivers manually or did you use the updater for the driver updates as well?

Bios is showing R10ET43W (1.28)

Directly from the Lenovo homepage?

I had this problem when rebooting shutting down / starting Linux (Ubuntu), Windows 10 was working fine. I found the following:

BIOS 1.28 is the problem. Downgrade to eg. BIOS 1.27, and everything works just fine. Hope Lenovo will fix this in next BIOS release.

Hello again. Thanks for this. It helped but not anymore. Also i bought another similar machine and voila, the problem is also in this machine!!!! Its nice to boot remotely and find out it hanged in boot cause of a charger...

Is this second system located at the same place as the first system? If so, are they both using the same electrical source?

This seems like a possible power source issue. The likelihood of two systems, this far apart in time, having the same issue is quite small.
