P52 only charges when lid is closed

2019-12-02, 20:36 PM

Hello,

 

When I first received my P52 with 45W adapter, the laptop would only take a charge when the lid was closed. When battery fully drains, laptop shuts down (even when plugged in).

 

I upgraded to 170W adapter and that solved the problem for ~10 months.  Recently the laptop reverted back to original behavior (using the 170W adapter).

 

Suggestions on how to resolve this please?

Hi!
First, P52 don't come with 45W adapters. They come with 170W ones. Could it be from another machine?

Second, make sure the Lenovo Vantage "Airplane mode" is not ON. Search the forum, there are plenty of mentions of it causing your problem.

If you got a 45W adapter with your P52, take that issue to your seller as it is NOT the right one.
