Since today I have a problem with my Lenovo P51 workstation laptop.
When the charger is plugged in and the laptop is turned off, the small ac adapter plugged-in indicator led on the back is turned on as normal. When I power on the laptop, the led will turn off and the laptop will receive no power at all. When the battery is removed, it is possible to boot into Windows, but after a few seconds the laptop will turn off.
I hope you guys can help me! This laptop is mandatory for my study.

I'm no expert, but I believe that this is normal behavior for Airplane Mode, in that it will charge the laptop when turned off only. Is this mode turned on?

Yes that was it! I mis clicked the airplane mode, but disabled it immediately after. The next time I started up the computer it acts like no power cord is connected to the laptop.
But the issue was the airplane mode in the power management window in Windows. When you disable the airplane mode at the internet options, the airplane mode in the power menu will still stay active! After resetting this to high performance the problem was fixed.
This is really something that should be patched by Lenovo or Microsoft! People can return their laptops to the shop because they might think it is defect if they don't troubleshoot themselves....
Thanks you some much for the help! Now I can finally take a shower after the heavy sweating haha.

Hello, I am having the same exact issue, but my computer will only flash on for like half a second, so I am not able to check the airplane mode option. Is there any additional information you can give me leading up to how you were able to/how I might be able to fix my Lenova P51?

In my situation it was possible to charge the P51 when its was turned off. When I turned the laptop on, the power was shut down after about half a second like in your situation. Is it possible to charge the battery for a while and boot in to Windows?

DaveW530, did you also check the power options? When you disable the airplane mode you also have to change this in the power settings manually.

I believe a 90w charger will charge the battery when the laptop is turned off
