Lenovo ThinkPad P50 charges only when switched off

Hello all,

 

I have the following problems with my Lenovo P50:

 

1. Lenovo ThinkPad P50 charges only when switched off. Charging light is switched off when laptop is switched on.

 

2. I removed the battery and plugged in the AC adapter power. The laptop won't switch on. The Ethernet lights switch on momentarily.

 

Does anybody know what's wrong? Many thanks. Ioannis

Hello,


Is the ThinkPad P50 in Airplane Mode?  If so, AC charging is disabled as a safety precaution (i.e., to prevent problems from drawing more current than an airplane seat power outlet can provide).

Hello Aryeh,

I have already tried this but the problem persists. I have tried another Lenovo power supply and it seems to work just fine. So, I think the power supply is busted.

Hello,

 

Is the the original power supply that came with your ThinkPad P50?  If so, it should be covered by its warranty.  If that's the case, call Lenovo support and see if it can be replaced.

I already did. Lenovo's sending a brand new one.

And we're back...

Move delayed but still coming
