Yoga C930 can't connect to wifi and often restart

Q: Yoga C930 can't connect to wifi and often restart

I like to keep my C930 in sleep mode. But sometimes after wake up, the laptop cannot connect to wifi (it cannot find surrounding wifi, and I cannot turn the wifi off). I will need to restart the computer to make the wifi work again. But when I restart the laptop in this condition, It cannot restart normally, it keeps restarting several times and until entering into repairing mode. I need to turn off the computer and open it again. It happens several times. It is hardware or system problem? And once I waked the laptop and screen didn't work. But it never happens again. Do I need to reinstall the computer or send it to repair?I just bought it for a month.

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

New YOGA C93013IKB with Bios 8GCN30WW. I have evertyhing up to date, but my wifi connection seems to randomly drop for about 10 seconds every now and then. Looking at the event viewer logs through my device manager I see an error message at the time of the wifi drops. Here is the event message I can see in the device manager  Device PCI\VEN_8086&DEV_2526&SUBSYS_00148086&REV_29\4&11c95301&0&00E4 had a problem starting.Driver Name: oem46.infClass Guid: {4D36E972-E325-11CE-BFC1-08002BE10318}Service: Netwtw06Lower Filters:Upper Filters: vwifibusProblem: 0x15Problem Status: 0x0 Do I have a faulty wifi module or is this something an update/settings change can fix? Looking through the forums with other post having wifi drops, it's recommended to uncheck a box in the power management tab but I don't even have that tab available in my wifi device. This is getting pretty annoying for something this expensive.

Hello, I've problems with the Wifi card. From time to time the wifi card is not recognized correctly and it gets the yellow exclamation mark in the device manager and says the device could not be started. I tried the latest driver of Lenovo website and the latest of Intel website. Same problem. If it hppens I have to reinstall the driver and reboot multiple times and plug in and out the power (I didn't find a proper way to fix it) and suddenly it is working again for some days. I suppose Energy saving/hibernating problems but I'm not sure. I'm just afraid that my new device is having a hardware defect ;-( Does anyone else have similar issues?Any idea how to fix it? Thanks in advance,Michael

Hi, I have tried to connect my Yoga C930 to some projectors at school. So far it worked fine in one classroom on one campus but failed in several classrooms in another campus. In the latter case, even I pressed Windows key and P and chose duplicate, nothing showed up on the projector screen. Then I saw a student using X1C6. I asked him to try. He just plugged in the hdmi cable from the podium to to his laptop and images showed up on the projector screen immediately. So, it means it is not the problem with the projector but problem with my machine or USB-C to HDMI adapter.  I can use the same adapter to connect a former X1Y3 to the TV at home. It worked fine. Using the same adapter and same TV with the C930, it does not work. Anybody knows what is wrong?

Hi,My brand new Yoga 720-15 IKB doesn't connect to my workplace wifi network which is a Mikrotik network. It does though connect to my home network or a mobile hotspot and works fine with them. I have installed all Windows 10 updates and Lenovo Companion updates. I have manually updated wifi card driver, I have also tried deleting network card and installing it again - but no success. Still doesn't connect to this one particular network in my workplace.To make it stranger my coworker has the same brand new Yoga 720, the only difference is that mine Yoga is grey and his is platinium color. We discovered also that two, supposedly the same computers  have different network cards (he has Intel, I have Qualcomm Atheros QCA61x4A. This is a bit weird).I have also found out his Yoga connects easily to VPN at our workplace, my doesn't.Any ideas how to solve it? EDIT: my current network card driver is 12.0.0.295

So I have had this HP Spectre for about a year now and it does not connect to my home internet unless I restart the modem. I restart the modem and it will work for a while. If i ever turn my laptop off or sometimes even close the laptop the internet will not connect and I will have to go unplug and replug the modem. This is extremely frustrating especially because of how expensive this thing was. Samsung Galaxy, siblings mac's, siblings iphones, even my Xbox One all connect to the internet but it is only this computer that always has a problem. I moved away for a couple months and at the house I was staying at my laptop connected to the internet with no such problems. I'm kind of assuming it's some kind of problem with this laptops adapter and my internet but that  makes no sense because my internet is fine with all of my other devices.  I have the latest LAN driver installed as well. This is a rather annoying problem and any insight would be much appreciated.

I have been relatively happy with my Yoga 900, but I have run into an odd situation and would appreciate any help.Specifically, my device functions well with my home router, but if I move to an area of the house where the WiFi signal is weak, and I get disconnected from the router, I seem to be unable to re-connect to the router when I then move back to an area of the house with a strong signal.I tried turning off the WiFi and turning it back on, but it still will not connect.It seems the only way I can get back online is to reboot.Is there a solution to this?For what it's worth, I do have the default 18.12.2.3 driver installed (Intel Dual Band Wireless AC 8260), and saw a post somewhere suggesting going to the Intel site for their driver.I am not someone who enjoys tweaking settings, so hopefully there is a simple step I am missing.Thanks so much to anyone who has time and willingness to offer a suggestion.

I bought my ThinkPad X1 Yoga for around $1600 CAD with 2 years on-site warranty. The Yoga C930 is usually around the same price or more expensive, but the yogadays promotion right now made the base model $200 cheaper even with 2 years on-site warranty. Would you guys say that at $200 cheaper, the Yoga C930 is worth it? It has dual fans and a bigger battery, those seem to be the main advantages.

As soon as I click the button to eject the pen, the laptop goes into sleep mode where I have to sign in again. The situation gets worse because sometimes the laptop would shut down randomly when the pen is ejected out or it is inserted back into the laptop.

I recently purchased the Yoga c930 to mainly draw on the go and do artwork in various apps and programs (mainly Photoshop, SketchBook, and Krita). However, this 2 in 1 is unable to download the wacom feel it driver ( I get a message saying that the wacom driver is not compatiable with the computer/tablet, which is wierd because the pen uses wacom aes technology) and I am having trouble with getting pressure sensitivity to work in almost everything I have tried to draw in. I even tried to change setting within the programs themselves, but the only one that really worked was Photoshop. Krita and Sketchbook still have no pressure sensitivity. There is also a Lenovo Pen Settings control panel for pressure sensitivity, but it does not really seem to make a difference in sensitivity when I change the settings there. Any suggestions as to how to get the pressure sensitivity to function properly on this computer would be greatly appreciated. I really don't want to have to return the laptop and get the Yoga 720 13" becuase this computer is really nice otherwise, but I'm starting to think that may be the only option if I want to have a better drawing experience.

Hello everyone! So after going back and forth which laptop i wanted i finally ended up getting a Yoga C930 which feels MUCH better compared to the 730 i had for about a day. The only concern i have for it right now is the fan noise is noticeable. I updated all of the drivers and did all of the windows updates, but it seems the fan is much more audible compared to the 730 i had. (I used the windows app and Driver Easy to do this) It's not entirely annoying but i do notice it. I also notice the laptop tends to get a bit warm. I know its only been a few hours but still its something i've noticed.  This is the exact one i purchased from Best Buy I've also noticed the Dolby Atmos Speaker System app apparently isn't compatible with my device? Also looking if anyone has recommendations on which usb c dongle to use so I can connect extra USB, display, and memory card reader? Some of the ones I?ve found on amazon don?t exclusively list if it works on the yoga c930

I have a brand-new Yoga C930 2-in-1 with a 1TB SSD and 16 GB RAM, which I'd like to run Ubuntu Linux on. I can't manage to boot from a USB (type A) pen drive yet, though. I managed to enter the BIOS (via this hint) and the "Boot from USB" option is "Enabled". When I exit the BIOS, though, saving the changes, having the USB pen drive plugged-in into the USB-A slot, Windows is booting up just normal. No USB boot happens, no boot menu is shown. Also, the usual pressing of buttons such as F2, F11, F12 or Del doesn't result in anything being shown from the BIOS. How do I boot from a USB drive then? Obviously, when there is a related option in the BIOS, it should be possible, shouldn't it?

I received this laptop as a replacememt of my defective yoga 720 the 18 October. After somw days of usage I can finally say that I ve got scammed by Lenovo, who sent me a testing unit with so mant problems! - Wacom pen and touch issues (such as ghosting and deas zones)- TouchPad gets disabled and became uselsss until next reboot. It also feels weird and it is kinda loose and imprecise! -KeyBoard acts weird and there is a noticeable input lag that I just can't stand since I am a programmer. -Hibernation/suspend/who knows who causes the impossibility to Wake up my laptop from sleep. When it happens I can only hard shut it down. - I've found some strange stats in the battery report that makes me think that I've received a testing unit with all of these malfunctionnality. My EMEA casw manager does no longee respond to my emails and I am willing to sens back this laptop and receive a refund or a new replacememt ( BUT NO MORE IDEAPAD LAPTOPS).

Lenovo Yoga C930 Impressions: Configuration Details ? 8th Generation Intel Core i7-8550U Processor? Windows 10 Home 64 - Upgraded to Pro? 14" FHD (1920 x 1080) with Dolby Vision? 12GB DDR4 2400MHz? Integrated Intel UHD Graphics 62? Iron Gray? Fingerprint Reader? Rotating Sound Bar with Dolby Atmos Speaker System? 256GB Solid State Drive, PCIe-NVME M.2 Since this is a replacement for the Yoga 920 I?ll use it in my comparison. I did have a Yoga 920 for several months.. The 12GB of RAM is an odd configuration but it is a nice in-between 8 and 16. I wish more manufacturers would offer this. I ordered from Best Buy and I paid $1299 for it. Ordering the exact same configuration direct from Lenovo would have been $1625. Not sure the reason for the massive price difference... I got the Iron Gray this time but I usually opt for silver (mica for the C930). It does attract fingerprints and smudges but for some reason it?s not as bad as I remember the Lenovo black being. I didn;t dig the light colored KB kets on the mica color so that was my main reason for going with the Iron Gray this time. So quick impressions: Screen Wow! For a 1080p screen this thing is fabulous. Brightness is improved over what i remember my 920 having but it still is not extremely bright. Speed It?s fast and snappy. I see no issues whatsoever and it?s on par with similarly equipped machines, as expected. The SSD is pretty fast. See screens... Read more

I just purchased a Lenovo Yoga C930, and the Pen doesn't charge in the dock unless I push the pen all the way to the bottom of the dock (and only if I'm putting the pen in, not taking it out), and even then it only charges up to 50%.
The battery lasts a while after I do this, and it takes 15 seconds for the battery to charge from 6% to 50%.
The charging contacts on the Pen itself seem straight and fine. 
The first day I used the pen, I used it heavily for a few hours and did not encounter a problem. 
Any suggestions? Is this most likely a problem with the Pen or with the laptop itself?

Today I recieved my new C930 laptop from Lenovo and right off the bat I knew that the touchpad felt bad.   The main issue with it is the imprecise touchpad.  When trying to make small movements or adjustments the cursor on screen does not reflect the movement I am making on the touchpad.  The cursor either doesn't move at all, moves in a different manner than my hand, or jumps randomly.Another major issue for me is trying to two finger click (right click).  Often times when I attempt the two finger click, it is registered as a single finger click resulting in a left click.  This problem doesn't seem to appear when I do a two finger TAP though.There are other minor issues im experiencing, but they are so minor that I would be willing to just put up with it. I've tried updating the HID-compliant touch pad and HID-compliant mouse drivers, but I am told that I have the latest drivers even though the driver versions are 10.0.17763.316 and 10.0.17763.1 respectively. (these drivers are from 2006)  I've also tried uninstalling these drivers and restarting my pc to download new drivers. Anyways, any help to solve this issue would be greatly appreciated.

Is the one that comes with the i5-version available separately? I haven't been able to find any guidance on lenovo.com and local pre-sales customer service didn't have any answer either unfortunately. Any guidance would be highly appreciated!
