Re: Yoga 920 won't charge anymore

2019-12-12, 23:59 PM

Hello Trailgem:

 

You said "So yeah... the factory reset didn't fix it. Lenovo literally tells you to purchase a new motherboard. Not true! I paid $41 for the part. Easy to install, works like a charm. "

 

Are you saying you paid $41 for a new Lenovo motherboard, and it resolved the problem with battery re-charge?  If so, what are you saying is "Not True!". 

 

I only got about one good year of use from the over $1200 investment in the Yoga 920.  I finally wrote off the investment with the battery re-charge problem.  $41 is not  a bad investment if it will fully resolve the battery problem.  The Yoga is current a paper weight, and I am skeptical to invest any more, but rather purchase a different, major brand (Dell, HP, other).

 

Please clarify you answer... Much appreciated.

 

Thanks

BroAl

I didn't buy the, mother board, charging port is separate from the mother oars and only connected to the motherboard by a ribbon. You can order they part on the Lenovo site for $41. No need to buy a motherboard. (That's what I've  saw posted from ) Lenovo support

Hello again Trailgem:

 

Thanks for your quick reply.  I am trying to find the $41 charging port you referenced.  Could you provide a part number, or guidance how to navigate the confusing Lenovo Shopping portal to find the same.  Thanks in advance

If you are comfortable try to disconnect the entire battery from the laptop for a couple minutes. I did this aswell as changed the charging port and it worked. I changed the charging port back to the original to see if it worked and it has been solid since. I had read something about a static buildup preventing the laptop from charging, not sure how accurate it is but worth a try. I hadn't used the laptop in a whole year so I took off the battery not expecting it to work anyway.

Thanks,

Sorry bud, not sure what the actual issue with these things are. I unplugged and plugged everything I could see on this thing. I also bought a new non oem charging cable and box from amazon. Not sure what did the trick for me. It's to bad I love the portability and style but to many bugs on them and it seems like a universal problem on the yoga 900 series.

Device ACPI UCM-UCSI. LENOVO YOGA 920-13IKB

2020-04-13, 6:57 AM

Hello, I use the laptop daily. I have been with the team for 6 months, so far everything is perfect.

Since yesterday the equipment takes a long time to load. 

Also, the USB-C ports do not work. Only 1 of them and loads very slow. From the USB CONNECTOR MANAGER, a danger signal appears: ACPI UCM-UCSI DEVICE. I

n Device Status: Windows stopped this device because it reported problems. (Code 43)

He updated the answers but the error continues.

I doubt whether to press the disable device and / or uninstall.

I do not know what to do. Please help. Thank you

This happened to my son's laptop as well. Just a couple of weeks after the warranty expired:

Although windows indicated it was at 74% it would not charge, the computer became really slow and the moment you unplug the power cable it would shut off.

I tested with different chargers, no result. Suspecting it was the battery I ordered  a new one, which took weeks, since the Covid-19 issue delayed all China imports. 

After the new battery arrived, I installed it and it worked... for a couple of days: 

Windows reported to charge it just a little (under 50%) although it was on the charger all the time. Suddenly it went back to the old crawl pace, 

and when you unplug the  charger it would turn off immediately. 

 

My guess is that the charging circuit on the board is faulty. Ridiculous for a one year old machine. Seeing this thread, it seems to happen with more people. As I 

already eliminated the net adapter and the battery as root cause, and most repair shops are closed, where can I obtain a repair manual to check the battery charging circuitry?

Hey, I did not have to replace the motherboard. Tried to find the part number, but I wasn’t able to. What I did... I logged I tot he Lenovo website, added my laptop in the support area. Somehow to found the area for parts (which is a 3rd party) anyway, wish I could be more helpful, the good news is, I didn’t have to replace my motherboard. It’s cost me $41 for the part. As of today, it’s still working. If I find the part number, I’ll post it.
