Q: Lenovo Yoga 720 13IKB No longer charging

Hello everyone, I recently purchased a Lenovo Yoga 720 13IKB. I've only have the unit for about three (3) weeks and the batter is no longer able to charge when connected to the power supply that came with the unit. I checked the AC adapter to make sure that it was properly connected to PC and it was. I plugged it to different outlets and it didn't help. I bought a replacement powersupply from my local MicroCenter and still nothing. I checked the Control Panel, open up the Power Options to see if there were any settings in there but nothing to show why it wasn't chraging. Then Opened the Device Manager. Under "Batteries" I saw two items, one for the battery and another listed as "Microsoft ACPI Compliant Control Method Battery". I Opened each item, which will brought up the Properties window. Under the "Driver" tab looked for "Update Driver." I went through the two options and did the same process of updating drivers. I went through the driver update process for all options. Once the drivers are all up to date, I rebooted the laptop and plug it in again. Then i unninstalled "Microsoft ACPI Compliant Control Method Battery" completely and reboot. Still the problem persists. I even updated all the windows Updates. Then I opened Lenovo's Companion app. I updated all the drivers that need updating and nothing changed. I still have my PC connected to AC power and the battery isn't charging. I opened the lenovo setting app and checked under battery sectiong and the Conservation mode is off and the battery stretch is off as well. According to Main Battery Condition status is Good. I have contacted customer support and I've been waiting now on hold to speak to someone for one (1) hour. Can anyone else make any suggestiongs?

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)

Is it not charging at all, or just stuck at around 60%. I ask because there i an option in Energy Management to select Maximum Battery Life, or Optimized Battery Health, and if set the latter (which I believe is the default), it will only charge to about 60 percent of capacity in an attempt to prolong the life of the battery. Setting it to Maximum battery life will allow the batter to charge to 100% and you will get a longer run time, but you may have to replace the battery sooner. If you leave the laptop usually plugged in, then optimized batter health is the better option. Cheers,

My laptop is only 1 year old and just ran out of warranty 10 days ago. I'm still going to call and see what they can do because my battery is completely drained, will not hold a bit of charge. I tried different outlets, nothing. I am plugged into the right charging port. Lenovo Vantage says my battery health is poor. I did not run any updates prior to this happening. I just ran every update except the BIOS which is not allowing me to since my battery is at 0% and requires a greater than 30% charge for safety. I do not know what I can do other than buy a new battery and try it out. Is this a BIOS issue or a battery issue? My battery was completely fine and I was just using the laptop a few hours ago. I put it to sleep and came back to it completely drained and not able to charge at all. Does anyone have any suggestions?

Good morning, I purchased a Lenovo Yoga 720 13IKB 80X6 last november 2017 in the United Arab Emirates. Everything worked perfectly until July, when the laptop shut down and wouldn?t turn on anymore. I tried everything I could without opening the device and cancelling the warranty , but eventually sent it back in the store where I bought it, and they had to change the motherboard.  Now, not even two months later, same problem. That laptop doesn?t turn on anymore, and this time it also doesn?t charge (the LED on the side doesn?t light up).  I, once again tryed everything I could that i found on the forums without opening the device pressing the on button for various amounts of time, pressin the ''reset'' one with a pin... nothing seems to work. Problem is that I no longer live in the UAE. So now I have two questions : - does anyone have an idea of what the problem might be? - Can I still send my device for repair where I live now for free with Lenovo?s IWS?  Thank you to anyone who can help out, it?s very much appreciated. Sincerely,  A disappointed costumer

So my Lenovo Yoga would start to boot and the light on the side and keyboard would light up, but then it would turn off again. Then it would start to boot up (without the screen actually turning on) and turn off again. It would just cycle through this, so I held down the power button for 10 seconds, and now it does not turn on at all- no lights, no anything. Any suggestions?

Hi Just want to share my latest experience after reading many posts of Yoga 920-13IKB (i7-8550 / 8G / 512G / 4K screen) incompatibility with Lenovo USB-C Travel Hub. I had this new Yoga 920 laptop for about a week, replacing my previous Yoga 900 (13.3", QHD+, i7-6560U, 256G, 8G). I have been using the Dell USB-C to HDMI/VGA/Ethernet/USB 3.0 Adapter (DA200) with the Yoga 900 without any problems. However, I can say with certainty that the Yoga 920 is incompatible with the Dell DA200 adapter. After reading many posts, I finally decided to purchase the Lenovo USB-C Travel Hub (4X90M60789) as a replacement. I had a local store rang Lenovo to confirm that it would work with my Yoga 920 before making the purchase. It arrived yesterday, and with two days of using and testing the connections Lenovo USB-C Travel Hub (Ethernet/HDMI/VGA/USB3.0); I can say that it works as expected. I'm not sure why Lenovo does not update their website to include the model Yoga 920 to be listed on the "Hardware Compatibility" list, as this will simply for the enduser to check - http://support.lenovo.com/docs/usb_c_travel_hub

Hi Friends, I have encountered problem while installing new OS (Windows 10 PRO) on my lenovo Yoga 910-13IKB which we prefer more than the default Windows 10 Home because I have used it more for job related matters. But after it automatically restarts as this was also included on the installation process, the next process became a cycle of basic information request-wifi connection-express settings then restarts again, and the same process continuously repeats. Aside from it, the screen's touch screen feature and the mouse pad are not working. Can anyone help me regarding my concern. I have attached file with images. Thank you.

Hello, Recently my CEO had bought a Lenovo Yoga 910-13IKB. It came with win10 preinstalled. I had worked on it for about 10 minutes and than the problem showed up: our local WiFi network dissapeared. I immediatelly took my laptop and searched for WiFi networks but no there was no my SSID at all. Then I had restarted WiFi router and network showed Up, but as soon Yoga connected, same again no network. I googled for solution and I did uninstall EMC and Lenovo Utility but that did not resolved the problem. Then I had tried to uninstall all drivers and than download and install them again but still the problem is there. Wherever Yoga connects WiFi dies. I found that some routers recognize something like DDos attack and so I dissabled that option on routers but again problem is there. Please can u give me solution to this problem because my CEO thinks that I am not capable of doing my Job (IT technician/Network administrator). Best wishes Adis

For the life of me I cannot figure out how to start a new post on this site so please forgive me for hijacking this thread.  I have a Lenovo Yoga 910-13IKB Model Name 80VF that died about 4 months ago - battery quit charging.  It was three months past warranty...sigh.... I took it back to Best Buy and they told me my charging cable was fine and to get it fixed I'd have to send it off for 6 weeks and it would cost me a minimum of $500.00.  Since I was using this computer for my job (I'm self employed) this really wasn't an option so I went to the apple store and purchased a mackbook pro.  However, I would like to get this Lenovo fixed and use it as a backup.  My questions:1.  Should I replace the battery?2.  Lenovo seems to be out of stock of batteries:  Is there another source where I can buy on line?  I can't find anything.3.  Should I look at replacing the little circuit board that connects the power source to the battery?  I can't seem to find a P/N for it (I removed that back plate of the laptop). Any help or assistance would be greatly appreciated.  Support for this product from Lenovo has been underwhelming to say the least. Jeff BueNewark, Texas, USA

I've recently bought a Lenovo Yoga 720 13IKB, considering the battery as one of its biggest pros due to some reviews and adds I read in the Internet. Unfortunately, even after a 100% charge, I can't get no longer than 4h30 / 5 h of battery lifetime prediction / battery lifetime.  I have already decreased brightness, I almost have no apps running in background, but unfortunately it doesn't gets better. The situation is even worse considering that I'm not doing anything but surfing online, texting in word or taking a look at some pictures in Windows Gallery. Have anyone experienced the same problem? Can someone please help me? Is that true that we can get 10h30 (or a bit less, I wouldn't care) like it was advertised or that was just a commercial bait? Thanks in advance!

Hi.  I?m not sure if there?s already forums, which has answers to my problematics, so please don?t feel irritated if there?s already someone, who had the answer in a another forum .  I brought my Lenovo Yoga 720-13ikb for about 8 months ago and until last month, them there wasn?t any problems. But then it suddenly became slow and laggy and I don?t know why. I had tried to update my graphic cards driver to the newest and had recently performed a fresh start via Windows Defended Security Center, but it didn?t help. Do you guys had experience the same problem or do you know what could be a possible cause? I also have to partions on my SSD; a C drive, where Windows 10 and all my programs are and a D drive, where it seems that there?s drivers from Lenovo. Can I combine them to one my drive or should I just leave it as it is? And if I can, them how? Then I?m also curious to figure out, how my laptop overall health is, since I?m a student, so I want it to perform as best as possible. Is there a way to figure out a laptops overall health and how the condition of my battery is?  I hope that you guys can answer my questions or at least notify me of any other topics, which have the answers to my problems .

Hi everyone,I create this topic today with a recent purchase of Lenovo Yoga 730 13IKB,I'm hving a issue with main ltters in my keyboard (with AZERTY)Most of letters in AZERTYUIOP (1st layer of letters ONLY) is not responding, i must let press or press lot of time to write these letters, it's weird because it's in a frequency of responding/not responding (sometimes it's very long and sometimes normal and responding fast). This issue is present on Xubuntu 18.10 and Windows 10.I disabled keyboard functions on the bios but it isn't this functionnality that makes lag.So I think it since I made the latest bios update, I was on IDE Sata Mode and the Bios update changed it to AHCI sata mode.It's maybe that is making issue.It's a big problem because i need to write fast in my job. So what I can do ?

I had a nightmare with the wifi performance and I hope that this post will help other ppl avoiding the same fate. the wifi had significant delays while pinging the router and all the downloads were so slow and unreliable. the issue started after installing Lenovo vantage and activating the battery conservation mode. this can be resolved by either disabling "battery conservation" or change windows power plan, wireless adapter setting, to  "maximum performance" while using the AC or the Battery. unfortunately, I spent few hours to figure out this issue which is caused by a simple setting mistake by the vendor.

So my Lenovo Yoga 910-13IKB (Out of warrenty) was working fine this past Friday in the morning. I plugged it in to my charger, closed the screen and went to lunch and when I came back the computer was really really slow. So I opened the task manager and looked at the processor and it was running at 13% utilization and clocked at .38GHz (Normal clock speed is 2.70GHz) I restarted the computer a few times. Did a full shut down, then restarted in saftey mode and ran a root kit scan (Found nothing). I then powered it off so I could get all my files off before it died, but when I restarted it later that evening it was dead (Powered off at 50% battery) So now I am stuck with a dead computer that will not charge. My thinking is that something on the Type-C charging board shorted out somehow and caused an errant voltage that messeed with the processors, drained the battery, and prevented charging. It could only be like 3 things right?-The charging port board (Type-C)-The motherboard (Which basically everything is soldered to, so I would not replace)-The Battery Any thoughts? If this is likely the correct diagnosis I might replace the board, but I do not want to spend $100 for nothing.

Ok, so I bought my Yoga 910 (4k/i7/16gb/512ssd) just a few days ago and, besides the fan noise (which I am currently working on) as well as recently discovering the issue I am about to discuss, I absolutely LOVE this machine! It is a workhorse and the build quality is amazing. That's saying a lot coming from a previous Mac user... Anyway, I was looking around today while trying to get the fan issue resolved and I noticed that the Full Charge Capacity (FCC) of the battery is only 75410mwh, while the actual Designed Capacity is meant to be 78000mwh. It is about a 4% performance decrease basically right out of the box, is that normal? I only ask because I originally bought the FHD/i7/8gb/256ssd version, before exchanging it for the upgraded unit due to liking it so much, and noticed that the FCC on the original one was actually 80102mwh, quite a bit higher than the designed capacity. Not sure if there is a setting preventing the PC to charge to the full amount or what? Maybe I just got a battery with lower ratings? Any help would be MUCH apppreciated!

6 months ago I bought a Lenovo Yoga 520 14IKBR, and now it won't charge any more while turned on. If we plug it in, the led goes white - and starts flickering orange after a few second, the computer seems to think that the power is not plugged in, and the battery doesn't charge. However, if we first switch off the computer, and then plug it in, it does charge normally. I guess therefore that there is no hardware problem, but a software issue.Somewhere on the internet we found a similar story, and according to them the solution would be a BIOS update. And indeed, the computer says there is a BIOS update waiting to be installed.However - because the computer thinks that the power is not plugged in, the BIOS update refuses to install - 'please plug in power'... So ... first question is of course if that BIOS update would indeed solve our problem. If not, is there another solution? If yes, how can we install that BIOS update safely while the computer thinks it is on battery power?

The power cable icon will display for about a second, then dissapear, then display, then dissapear, etc.  It will even change the brightness of the screee as it attempts to switch power modes from battery to power.  The only way to stop this behavior is to unplug the cord completely. 3) The laptop shows that the power cord is plugged in, but states that the battery is currently discharging.4) The laptop shows that the power cord is plugged in, says its charging, but the battery continues to drain even though it says it is charging. Windows 10 is fully up to date.  We have run all Lenovo software updates so all Lenovo software is up to date.  The BIOS is also up to date (the June '17 BIOS).  There have been no recent new software installations or physical impacts / changes to the laptop. I have purchaced a 3rd party charger that matches the specs of the Lenovo charger and the same 4 situations happen.  I have confirmed that the charger works to charge other devices.

So I have a Lenovo Yoga 720 that is about 2 months old which was originallly not charging when plugged in (it said it was plugged in and discharging) and it was associated with phantom taps/clicks of the touch screen all over the place. I resorted to replugging in the charger and restarting the machine to see if it would fix it and sure enough it fixed the phantom touch screen tap issue but the charging issue kind of remains. When it is plugged in the battery monitor in Windows 10 says that it is at 11 percent currently but then when I take the charger out the percentage jumps higher and says that it is at 13 percent. And the same thing happens over and over again as a repeated process. Any idea what could be the issue and what steps can be taken to fix this??

My laptop suddenly stopped charging. I've checked the adapter, it still provides the USB power to charge my mobile phone. I can also charge my phone from the residual charge in the battery. So the remaining possibilities are that the charger isn't producing 20V power, the wire has gone bad or there's a problem within the laptop.  The replacement charger costs a pretty penny and will take time. Is there any way of checking if the wire or the charger block are working or not ? The alternative of taking it to Lenovo sucks, can't work for a while. ThanksRahul

A:Lenovo Yoga Pro 3 1370 not charging

First, is it still under warranty? Many are.   If it is, call support.   Do you know anyone with another machine where you can borrow an adapter?  The Yoga 700 and Yoga 900 use the same sort of plug except they have a max power draw of 65W.  The 700 and 900 don't work right on the Y. 3 pro's 40-w adapter, but your machine is OK with the larger one.  I looked at the adapter and the power cord and  it would be difficult to test the output with a meter, without shorting something out.  I have all sorts of tools and meters, and I takeapart and fix machines, so if it were mine, I would open the machine and pick up the input leads from inside and test with a meter.  If you are not comfortable doing that kind of thing, don't risk making it worse.  DON'T OPEN UP AND WORK ON A MACHINE THAT IS STILL UNDER WARRANTY.
