Lenovo Flex 3 battery doesn't charge, ok to run without?

Hello,

 

I have a much-beloved Flex 3 maybe 10 months old.

First question: The battery says it's charging, but it's not actually charging. I"m guessing the battery's shot? I don't have the tools to open the thing up and try disconnecting the battery yet.

 

Second question: Assuming it's dead, is there any problem with runnning the laptop just on the power adaptor? I did see that for other models this seems to be ok. I'm outside the US right now and have little hope of getting a new battery until July. Every day the battery decreases 1%, and eventually it'll be gone. I can wait until I get back if I can run on a dead battery. Currently at 57%.

In case it's relevant, I'm in West Africa in 220V land.

(As a side note, I dropped the thing when I first arrived and the screen cracked, but it hasn't lost any functionality so far, so kudos to Lenovo for that!)

 

Thanks in advance for any help or advice. I do appreciate it.

Hi Tatooinedweller , 

 

Welcome to the Community Forums. 

 

Even without opening the laptop, you can try if the charging status LED (page 28) would change while plugged in for 1-2 hours not turned on. You may also create a battery report to check.

 

Usually running battery gauge reset as another option (but may or may not further exhaust battery) so it is better to start first with basic steps . If you have an active warranty coverage, try to get hold of technical support and have it reported this early and have the issue documented. Inform them your current location for further recommendation.

 

It would be ok to use the laptop on direct ac connection but plugging it on a surge protector is an advantage although the charger would say its autovolt ( for both 220/ 110v) capable.

 

Hope this help answer your query. 

Update us how it best goes on your end.

 

Regards

Sorry to hear that you are having battey "plugged in, charging" but the percentage doesn't go up issue. 

There are a few of us having the same issue and so far nothing has worked for us (even changing the battery!).

No one knows what the solution is and Lenovo has not replied to all the requests with a solution.

Here is the original post

Let me know if you can find a fix to the problem.

Thank you! 

Everything's a bit delayed due to internet connection issues, but I will try those fixes. 

 

See update below.

Re: Lenovo Flex 3 battery doesn't charge, ok to run without?

Update: I've found a corner of the software that tells me my battery is fine, but my adaptor has insufficient power to charge it. Additionally, when I boot it up right after I plug it in, it flashes battery mode (dim screen, not plugged in, etc) a few times before finally stabilizing. So it might be the adaptor? 

 

I thought my wall outlet might be bad, so I tried plugging it into my power stabilizer/converter (current is not reliable here), and it didn't show any success. 

 

Next, I tried switching to conservation mode, shutting down the whole thing and charging it for two to three hours. No good. 

 

The next night, I unplugged the cord from the outlet instead of just the laptop, thinking maybe that was harming the adaptor further and not wanting to lose any more functionality (I usually just unplug the computer overnight and leave the adaptor plugged into the wall, although everything is unplugged during the day). The laptop had been shut down via hibernate as I normally do.  

Then in the morning, I plugged it in, waited a minute, and booted it up. Battery was at 60%, the max on conservation mode. The internet was bad again, so I left for work; if anything further develops, I'll update.

Re: Lenovo Flex 3 battery doesn't charge, ok to run without?

So you're saying to charge with the computer in hibernate mode? Also, regarding your concern regarding the charger, I have replaced my charger and the problem persists for me. I have the same exact symptoms as you (including screen flashing from the plugged in/not plugged in constantly switching). I will try charging in hibernate mode tonight and report back tomorrow.

Re: Lenovo Flex 3 battery doesn't charge, ok to run without?

Update: I'm still consistently recharging to the maximum on conservation mode -- 60%.

I don't think it's a matter of charging in hibernate, because that's how I've always done it. I think changing the battery settings might have done it. Either that, or there's something about unplugging from the wall socket and then the laptop, but if buying a new adaptor didn't work this seems less likely.

 

Let us know how charging in hibernate worked! If not, try switching to conservation mode.

Re: Lenovo Flex 3 battery doesn't charge, ok to run without?

Thanks for replying again, I tried charging in conservation mode while both using hibernate and simply shutting it off to no avail. Was the conservation setting the only one that you changed before it started working again?

 

 

EDIT: Well, as of today the laptop will no longer power on under any circumstances. It seems that the motherboard has gone. I've had this laptop less than a year and have been plagued with this charging issue and the motherboard destroying itself. I guess I'm going to have to spend the money I was going to use for my tuition to buy a Dell or Eluktronics laptop. Good luck with the charging issue guys.

Sorry about your luck with the motherboard Smiley Sad

I hope that's not down the line for all of us, although mine's still under warrenty for another month. 

 

I was also making sure that it was unplugged from the wall before unplugging from the laptop. (And sacrificing small children-shaped USBs to the computer gods. Just kidding.)

 

It hasn't charged again since the last update, but the battery hasn't really fallen either.

 

Is there any way it could be a virus?

Re: Lenovo Flex 3 battery doesn't charge, ok to run without?

The diagnosis fot my laptop from a repair shop here in town was the charging circuit is dead and needs motherboard replacement. I opted out for not getting the MB replaced as it was expensive.

Since this is not my main machine, I'm going to try to find the issue on the component level and see if I can replace the faulty component. I was reading somewhere that it most probably is the MOSFET and is not that hard to replace. Let's see!
