Q: Lenovo Yoga C930: Laptop switches modes randomly, sometimes thinks it's shut and just goes black!

Hi. My keyboard stopped working out of the blue, and whenever I open the laptop it goes into tablet mode. Switching to laptop mode does not fix the keyboard issue. Any help?

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.)

Problem seems to have fixed itself, but I'm still worried.It's like something is making the laptop confused. Sometimes it doesn't know if it's in tablet mode, laptop mode, or closed. There's been times where the screen just shuts off, and I need to close and open the laptop again to get it to work. In fact, it was this that caused the issue in the first place.Is there anything that might be causing this system confusion?

Hi forums, it seems that my old 11S might be breaking down on me...So laptop mode, tent mode all work fine as far as I can tell.  However, when I fold the laptop all the way (Tablet Mode), it will start bugging out, constantly locking and unlocking rotation, and enabling and disabling rotation. I can't quite tell if this is caused by physical motion, but if it is, its sensitive to the slightest jolt or pressure.  At this point I'm attributing the problem to hardware, but is there anything I can do to remediate this?  I don't really mind opening it up either, its way past warranty.  Thanks!

Hi The laptop was working perfectly until i updated the intel HD graphics driver to version 23.20.16.4849 (27/10/17).  As soon as I did this, the machine would not wake from either sleep or hibernate mode when the lid was shut. When I open the lid it will either enter staright into a black screen, and I can hear the fan spinning with lights to the right hand side but no further activity. Sometimes the Lenovo log appears on the screen first and then enters into a blank screen state. I am on Bios Lenovo C6CN34WW 29/10/15 As soon as I press and hold the power button to turn off, and then turn on again the machine loads into windows perfectly, with a visible display.  Any suggestions how to fix this? Thanks

Greetings, I have a Lenovo Yoga 730 15 with 4K and NVIDIA GTX 1050, which has a screen that blacks out at random. Based on what I read in other threads, it could be an issue connected with the auto-brightness and auto-dimmining settings. So, I turned those features off. Though it has been happening less, it's still happenning. Could anyone tell me what other settings I should check to resolve this issue? Thank you for your help.

Hello, I would like to preface this by saying that I have spent a lot of time trying to figure this out myself and I would greatly appreciate your help. My laptop is a Lenovo Yoga (Machine Type Model 20CDX00) that has problems with shutting down and sleeping sometimes. The problem started after I restored my laptop with a clean copy of windows 10.  I installed all of the drivers and I also updated my BIOS.  I noticed that sometimes my laptop would not shut down completely and the battery would just drain in the blank screen that I couldn't do anything about.  This also happened with sleep to.  Not all the time, but sometimes.  I tried to turn of hibernate and also fast start-up.  But, that did not work.  I, then, restored my computer again and I tried to reset the BIOS to the original BIOS.  I am still having these problems even after the restore which makes me believe that the BIOS is at issue becuase it is ROM and would not have been changed by my restoring of the laptop.  But, I did try to reset the BIOS to a previous version.  So, I am stuck and I do not know what to do.

The pen that comes along with the Lenovo Yoga C930 isn't working on my laptop. The battery shows full and I barely ever use the pen but I have many plans of starting to use it. It really saddens me that I left an HP laptop for a Lenovo just to come to this problem. It has only been 1 month since I've bought this laptop and I barely use the pen but then it doesn't work anymore. There was a time where I didn't charge the pen for a whole week but I put it back and didn't touch it ever since. It's impossible that anything could have happened to the pen because I left it in a drawer. The touch screen works perfectly fine.... I don't know what to do and I am really really sad/disappointed. I need help with this if anyone can let me know of anything I can do or what's wrong?

My first ever Lenovo laptop is coming next week and I am so excited because it has been a big investment for me!! I hope to make it last at least throughout college, and since I can be kind of klutz, I?m already looking into what protective measures I can take. I found a lot of cases on amazon, but the main design flaw seems to be that they don?t allow the laptop to go into tablet mode, which is a bummer since the reason I bought a 2-in-1 is for doodling. Anyhow, I?m just curious as to what other Yoga users or what recommendations there is. Thanks in advance!

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).

Is this normal? i expected to get around 9-10 hours for the web browsing. Also keep in mind i am on better performance so not the best performance or anything. Ya if i lower the performance even more i might be able to get a little more but i dont think thats normal. I dont have the 4k version either just the regular.

Torn between battery life or better display. I do occasional work with graphics and have been wanting a touch screen I could draw on since I was a kid (I am a genXer, enough said). On the flip side, the whole point of a laptop - esp a 3lb/14in screen - is portability. I've read that the small screens don't matter much with the resolution differences, but when I viewed them side by side, I could see a difference with images (but not so much text). If there wasn't such a huge difference in battery life, I'd just get on the 4k. Either way I have the option of purchasing a 4k screen (that I can't draw directly on) or an external battery pack (that I would have to lug around).As such, I am curious to know why people choose a UHD over the FHD? Are you happy with your choice? Did you find a workaround for battery life on days you needed to use it for long periods of time (such as travel or presensations)? Thank you!

A:Lenovo Yoga C930 users - why did you buy the 4k screen?

The battery life for me is great. The model I purchased was an excellent deal and came with UHD. But, my I do have touch screen and the C930 comes with a pen, so you can draw on it. Many people prefer the FHD over the UHD. I've had both and really don't have a preference.

Hey folks, I got the Yoga c930 and so far I'm loving it, save one issue--my shift key feels kind of loose (but sticky) and makes a different noise if you accidently hit it the wrong way.  Since it's not a pc-breaking issue, I don't want to have to send it in unless something else goes wrong, but I was wondering if anyone has tried any DIY maintenance on Yoga Keyboards.  I'm worried I might break a clip since even though their are videos for the Yoga 710 on YT, I don't know if they switched up the mechanism for this generation.  It sitll registers the click, so functionally--no issue, but it feels like a defective key that could just completely break out of the blue.

Hi, after purchasing my Lenovo Yoga C930 in November 2018 it worked completely fine until 4 days ago. At some point, I started noticing some slight flickers in the form of very thin lines that would span over the whole screen width. I then updated the Graphics Card drivers which solved the problem for two days, then it came back. Since yesterday, there are now some hug screen flickers (similar to this, but a bit less bad: https://www.youtube.com/watch?v=6SIHJYWsFCI ), which are increased if the laptop is on battery mode as opposed to when it is plugged in. I tried to see if there was a difference between the different power modes in battery mode, but it doesn't seem to be the case.All the drivers are up-to-date and I am very dependent on my computer for work, so I would rather not send it in if I can avoid it in any way. Has anyone had this issue with a C930 and managed to get rid of it? System information:Windows 10Intel(R) Core(TM) i7-8550U CPU @1.8GHz 1.00GHz16GB of RAM Thanks in advance for useful feedback!Cheers,Julia

Good day, I just received the Lenovo Yoga C930 and the pen doesn't work. The laptop does't recognize it and there is no way (app or settings menu) to install it, syncronize it or try it. Microsoft Windows 10 pen settings is for the surface pen and the Lenovo Pen settings is for the Lenovo Pen with the top bottom. Nothing for the fancy new pen that is stored in the laptop (not even in the product guide - way to go Lenovo!).  I have been trying to call several times Lenovo technical support and the dial menu is horrible. I haven't been able to reach a technical support representative for the Lenovo Yoga C930. This is the worst service per purchased item prize I have received in my life.  I really hope that someone can help me. This purchase was supposed to be a good experience and so far it is just pathetic.

Hi Oolee,
 
Welcome to Lenovo Forums.
 
Did you try booting from safe mood? There is also a chances, if your cables are intact and not loose (VGA Cable), or the monitor loses power.
 
Please go through this HMM for hardware assistance.
 
Method 1:
Any external hardware can cause this (like a keyboard or mouse can cause system to sleep to save the power) 1. To change this go to ?MANAGE? by right clicking on the ?MY COMPUTER ? icon on the desktop . 2. Go to DEVICE MANAGER. 3. Click on the keyboard or mouse or any other USB devices and right click on them and go to PROPERTIES and select POWER MANAGEMENT and untick the appropriate box.
 
Method 2:
Control panel > Power options >Choose when to turn off the display (look for this in the side bar)  Set ?TURN OFF THE DISPLAY? to NEVER Set ?PUT THE COMPUTER TO SLEEP? to NEVER. And then continue to ?Change advanced power settings? Go to "SLEEP" Set "SLEEP AFTER" to NEVER. Set ?ALLOW HYBRID SLEEP? to OFF. Set ?HIBERNATE AFTER? to NEVER. Go to ?DISPLAY? Set ?TURN OFF DISPLAY AFTER ?to NEVER. Press APPLY and then OK.
 
Let us know how you get on.

Shashi

I just purchased a Lenovo YOGA C930-13IKB this past Thursday (5/16) from Best Buy & found that the lower left & upper right corner do not sit exactly flat on a hard surface causing it to wobble.  Doing a quick search online I found numerous reports of other Lenovo laptops with this concern but was curious if anyone has come accorss this on their new C930 & if so what was the repair/replace remedy? I checked all the rubber "feet" on the bottom & they all appear to be of same size but yet there is a few mm gap (screen open or closed) on left as you can see in attached picture. Greatly appreciate any help & guidance...

A:Brand new Lenovo Yoga C930 wont sit flat

Welcome to the Community!
 
I've run into this with a number of appliances and devices. Sometimes, it's a warped cabinet. Sometimes, the rubber feet are slightly different (usually due to a bad glue job). Sometimes, it's the surface, itself. The "redneck" fix is to just use an emery board on the rubber pads until it sits flat. But, since you just bought it and if it's out of your tolerance, I'd haul it back and make them unbox and test the replacement in front of you.

I just got this Lenovo a few weeks ago and it has worked fine until today! The screen was flickering every few seconds, so I followed the steps I saw on the forums to fix it. Nothing worked, so I tried rebooting my computer to see if maybe the drivers needed the computer to be restarted to work. Now, the laptop won?t turn on. The LED shows the machine as being powered on, and the keyboard will light up, but the screen remains completely black. The Lenovo logo doesn?t show up or anything. I?ve tried rebooting with the AC adapted plugged in (even though the battery was fully charged), I?ve tried restarting holding down shift + f8, and holding down the volume up key too.

Hello, We have 3 docks (Dell D6000, Thinkpad USB C dock, and a pluggable usb c dock) at our office and just recently purchased this laptop to connect with one of the three docks and use 3 external displays. For some reason, when connecting monitors to all 3 ports on all three docks, we are unable to get all 3 displays and the laptop. We can only get 2 displays and the laptop as a third. That being said, on the pluggable dock, we were able to get all 3 externals and the laptop as a fourth about 1 in every 15 or so connects. Otherwise we get 2 displays and the laptop. If we disconnect one of the displays, we can get one that was off to turn on, but we are again stuck with 2 displays and the laptop. The Think pad docks gets all of the displays, but at horrible low resolutions (it has 2 DPs and a VGA). Their is no consistency at all and I'm trying to avoid returning the laptops. We have checked that the latest drivers are installed and installed the displayport drivers from their website. Another weird thing is that sometimes the docks are charging the laptop and other times it shows "plugged in, not charging" on all 3 docks. We have a dell that is not as nice body wise, but connects to all 3 docks and gets 3 external and the laptop, but these yogas are nicer. Is what I'm trying to do possible with this laptop?

I was quite concerned about the 20Mbps download speeds with this NEW laptop on my Asus AC87. It uses the 5GHz MIMO with beamforming and should get 95Mbps. My Note 9 for instance with 2 x 2 MIMO gets 95Mbps. It is a HUGE and disappointing difference. All I did was go into the settings and change the bandwidth from 80MHz down to 40MHz and so far the problem seems to be solved and it didn't affect the speed of other wireless devices. I'm wondering of course if anyone else experienced the same issues. This may mean I'm getting a lesser theoretical speed but the practical speed is what counts and it works now. Grant

Hi All

(Windows 10)

Bit of a conundrum on my hands. My laptop ASUS ROG GL553V is powering off instantly and consistently within 10 - 30 seconds of being powered on. Some small amount of background:
Less than a year old (so could return for warranty);
Had an issue with the ASUS ROG Gaming Center spinning the fans up to 100% when gaming and causing the laptop to shut down automatically. This was rectified by uninstalling said software entirely. No issues for 2-3 months since;
The shut down doesn't occur when something particular happens, it is seemingly 'time based' (like it's overheating and if you see here: https://rog.asus.com/forum/showthre...-Overheating-Throttling&highlight=speed+crash this is super common).

Instead, the laptop (cold as anything, no heat whatsoever) will shut down in bios, starting windows, logging in and sometimes I get 5-10 seconds of desktop time.

Putting it in the fridge netted me a small extension of time, but very very little. Just enough to see that the UEFI reports the CPU as 105c. HWM (briefly open) says the CPU is at a comfortable ~40.

Now obviously the CPU isn't 105c as I would absolutely be able to feel that melting a hole in the laptop, and HWM knows it's not. The UEFI is somehow detecting the CPU as 105c, and triggering a shut down. Now to me, the obvious solution was to update the UEFI via pen drive but I won't have enough time! And insofar as I understand, a halfway updated UEFI is a quick way ... Read more

Whenever I'm playing high performance games my laptop switches itself off.

All the signs point to overheating, but I think it's something else. Firstly, I can switch my laptop off immediately after this happens with no obvious ill effects. My laptop actually has overheated before and I couldn't switch it on for a good 30 minutes afterwards.

Secondly, the switching off seems to happen somewhat randomly. On Saturday, my laptop switched itself off at least 5 times, however the next day, I played Team Fortress 2 for 3 hours straight without any problems, and my laptop was a fair bit hotter during the 3 hour session than it ever was during the LAN Party. Today it's switching off even more frequently, I can't even get 30 minutes of gaming in without this happening. Outside of high performance games, my laptop is perfectly fine.

A:My laptop randomly switches off.

Welcome to TSF.

I would look into other possibilities of the random restarts. It doesn't look like a malware related issue. Have you ran a memory check yet? Google for memtest and use that tool to run a memory test.

There are probably malware that may cause this kind of issue, but I'm leaning more towards a hardware related issue. Try posting in the hardware board for more help.

Hi,
My Dell Inspiron 15R 5520 laptop switches off at completely random times. I've given it for service 3 times and the frustating part is during their testing, it works completely fine so the repair guy can't figure out the problem.
After it switches off, it doesn't boot for a while and just gives black screen and a bunch off beeps. ( 7 of them at intervals)

I did a diagnostic and got a CPU fan error 2000-0511 Validation 130122.

Please let me know what is this issue and how to solve this. 
Regards,
Mandar. 

A:Laptop switches off randomly

Sounds like the CPU fan is not working -- leading to overheating and shutdown.  Start by replacing the fan:
<<www.parts-people.com/index.php?action=item&id=13933>>
<<www.parts-people.com/index.php?action=item&id=14456>>(the fan is different depending on whether the system has Intel or AMD video).
If that doesn't solve the problem, the mainboard is the next possible suspect.

Im having issues with the following for my new laptop: -when watching some videos on netflix, for example, the contrast of the screen changes almost as if the tv scene has a flickering light turning on and off repeatedly-speakers make static, pop sound and the volume needs to be at 100 just to hear something-in power options, there is no option to switch from balanced to performance. the only option is balanced Would appreciate help to fix these issues or know if others are having the same issue!

This is the same laptop that was causing problems way back in October 2003 (http://forums.techguy.org/t175403.html). To summarize briefly, I got it working again by removing one of the two RAM chips which was kaput and later installing another. Recently, however, the same machine has begun misbehaving again -- it switches off randomly. This is not hibernation or standby; the only way to get it going is the reboot.

After searching the interweb for a solution, I figured the closest answer was probably overheating: the fan did seem to be on a lot of the time. We purchased a cooling pad which certainly put paid to any heat issues -- and made life a lot quieter -- but the laptop is still randomly shutting off.

It doesn't seem to be linked to memory load -- it will fail while it is just idling -- and there doesn't seem to be any pattern to the problem: it will go days without going belly up and then fail twice in 30 mintes.

It has a firewall, anti-spyware and is anti-virus protected so I'm pretty sure this is not mal-ware related. All the relevant Windoze XP updates have been done. I even increased the size of the partition to make sure it wasn't a pagefile problem.

My next likely candidate is faulty RAM: either the chip that survived 2003's accident has finally begun to lose it, or the replacement chip is on the slide.

Is this likely? Or does anyone else have any ideas?
