Thinkpad P53 Battery stops charging when turning airplane mode on

2020-03-07, 19:00 PM

Hi

 

I noticed a really strange issue today which gave me a mini heart-attack.

 

I was out and working on my P53 on battery. When it got to around 30% battery level, I turned airplane mode on, to conserve some battery so I could use it a little longer. Anyway, by the time I was done, the battery level was around 20% ish.

 

Went back home, plugged the laptop and turned it on. All of a sudden I got that error message that says something along the lines of "The connected AC adapter has a lower wattage than the recommended .. ". I freaked out. Last thing I want is to have to deal with Lenovo support and ship the laptop in for a repair.  

 

 

I tried many things, using different power outlet, disconnecting and reconnecting the power adapter, even unplugged the internal battery and tried to boot it just using the power adapter. Nothing helped. When I would get past the error message and manage to turn the laptop on, the battery wouldn't charge. My last resort was to use my USB-C charger from my T480s I thought I can charge the battery and try again if it helps. I should be able to charge it using the Thunderbolt port right? No luck, that one didn't charge it at all.

 

Finally I gave up, I thought I will just turn it on one last time, save all my work and do a final git push, before trying to contact support. Git push didn't work because I guess I was still on Airplane Mode, as soon as I turned off airplane mode, the **bleep** thing started charging and working as expected.

I thought maybe I am going crazy, how can the 2 be related. I tried toggling airplane mode a few more times and yes, for some odd reason, it doesn't charge when in airplane mode. It seems like a bug with the power management software.

 

Do you know if there is a place I can report this issue to be addressed? Not sure if it matters, but my laptop has wifi + wwan card.

 

Anyway, just wanted to put it out there and see if anyone else noticed this or if anyone encounters this issue and needs help.

I moved your post into the P and W model area. You might want to have a look at this post, however:

Hi

Thank you for moving it.

 

Yes I saw that article afterwards, but that doesn't seem like a solution, just a workaround. What if your battery is dead completely and there is no way to turn on the laptop to disable airplane mode? I was lucky it had a bit of battery left so I could turn it on and disable it.

Hi, I also have the same laptop (P53), and I noticed that in flight mode the battery stops charging, like you wrote

I'm afraid that if the battery runs out and the computer is in flight mode, I won't be able to charge the battery and not turn on the computer.

 

If you had any other solutions?

Following up on this myself, is there an actual solution to this problem yet?

A solution, not a workaround. Turn off airplane mode is not a fix for not being able to charge with airplane mode on.

 

This seems to be widespread across Lenovo laptops. 

It is a little crazy that my $5000 thinkpad laptop cannot charge with airplane mode on.

 

When laptop is completely dead and windows cannot be logged back into to disable airplane mode as well what is the solution?

Hello,

 

This is not a bug or a defect but a safety feature.

 

Airplanes with 100 Watt charging receptacles are becoming more standard, however, as I recall, the ThinkPad P53 requires a 170 or even a 230 Watt charger, depending upon its configuration. 

 

Plugging a device into an airplane seat power outlet that consumers 1.7-2.3 times the wattage could cause the outlet's circuit breaker to trip.  If there is an electrical problem with the outlet, though, an electrical fire could occur aboard the airplane.


The Airplane Mode option on the computer disables AC charging so that in case the computer is plugged into an outlet with faulty circuit breaker, it just won't charge, as opposed to starting an electrical fire aboard the plane in which you are flying.

 

Regards,
