Model: Lenovo Yoga 700-14ISKProcessor: Core i5-6200URAM: 8 GB RamHard Drive: 256 GB SSDGraphics Card: NVIDIA Geforce 940M + whatever integrated graphics card comes with this model, unsure.OS: Windows 10 Hi, I've been experiencing a problem with my Lenovo Yoga 700 laptop where the screen remains permanently black. My computer will turn on, or so it seems, but nothing appears on the screen. I've tested many potential solutions to try to fix this issue, which I'll list shortly, but unfortunately nothing I've done so far has worked. This issue first appeared this past Monday on June 18th, 2018. I happened to be using my laptop at the time, when the screen suddenly went black. As far as I can remember there was no noise when the screen went black. I tried to get the screen to come back on by increasing the brightness and pushing the screen backlight button, but neither worked. So I forced shut down my laptop by holding the power button in, and then shortly restarted it to find the screen was still black. However, when powering on the laptop the fans work, the keyboard lights come on (and I can toggle them on and off using "FN + Spacebar", tho I've discovered that after the laptop has been "on" a little while, say 5 minutes or so, the keyboard light gets stuck on and "FN + Spacebar" will no longer toggle it off), and the Power Button Light on the side of my laptop turns on. Since then I've researched the issue for Lenovo laptops, and luckily most forum topi...

Hi,
 
I bought Lenovo Yoga 500-14ISK (i7 6200, 8GB RAM, 1TB, 2GB Nvidia). Machine performance is not as good what the specs looks. Machine took quite long to startup initally, when you close lid the machine goes into standby/sleep mode but upon opening the lid machine doesnt show up anything on screen and BIOS setting shows System Memonry a RAM as 0MB.
 
This machine has already been replaced once as it was brand new and found these issues 2 days after buying, they gave me a new machine but new also has same issues. I updated all drivers, windows update and even tried one key recorvery (also windows 10 reset - remove everything). But problems remained same.
 
Upon searching found that it was issues with other Yoga 500 machines too had same issues and there were some URGENT BIOS fixes. Being techinical guy at first thought did not try using the BIOS utility on this machine as model number were different (In list of machine supported this machine was listed). After trying hands on other solutions, I tried running the BIOS utility and it failed (as expected - This BIOS utility is not for this model).
 
I can take machine back to retailer but know the problem even if they give me new machine again will have the problem in that too.
 
The BIOS update are not available for this machine is huge disappointment. Even when tried reaching the LENOVO support in UAE no solution was provided (as they redirected to local service center  which I dont w... Read more

Hi All, I had also bought the Yoga 500 i7 (14ISK), had same issue of closing the lid sending to sleep. What I found was that when I booted the machine first time its BIOS was updated from DC25WW to DC27WW which created all the issue. I some how found same machine with older BIOS which was working pefrectly fine. So I suggest go to below link download and install the latest BIOS i.e. DC28WW as it has resolved my problem http://support.lenovo.com/ae/en/products/laptops-and-netbooks/300-series/300s-14isk/downloads/ds1053... Please have a look at the supported system in list from above link, or else try finding the BIOS for your laptop model. Hope this helps everyone. Regards,Mahesh

I have been suffering the, what seems common, screen flicker issue with my yoga 500 when on battery. After reading through some threads i discovered the problem was either, Drivers or Bios. After trying both drivers from lenovo themselves, and the latest from intel/nvidia the problem still remained.i then tried updating the bios. After windows shut down, the Phoenix bios updater stated a message that the bios had been sucessfully updated. The laptop then restarted and no longer posts or goes into windows. The Nova button also has no function and just causes the keyboard to illuminate and the fan to spins for 10 seconds before stopping.(Same as power button)Any advice?

Hey everyone, My Intel HD graphics 520 driver continuously crashes and basically shuts down my computer. The power button/keys are still on, but I just get a black screen (with some light behind it), as if it is in sleep mode, and I cannot wake up my computer anymore. The only solution then is to just force it off by holding the power button and restart it. I feel it happens at random, but it seems to occur more often when I'm playing a video or something (although that may just be a coincidence). I've had this problem for a long time and have tried several times to reinstall or update the driver. Because I got so fed up with it I just disabled the driver and used the NVIDIA Geforce 920M driver, which works sort of fine with the only big disadvantages that I can't increase or reduce the brightness of my screen anymore and can't run certain programs/games properly. So, therefore, I'm still looking for a solution.  Can anybody help me out?

I have some problems with the Lenovo software. Lenovo Account Portal does not launch Lenovo Companion and Lenovo Settings. Also, Lenovo Solution Center is missing from the Start Menu. The second problem is that some tiles are blank in Start Menu. Seemingly it's the apps that aren't Metro. I'm not sure when the problem started, but I think it was like that since I got the PC. If I right click the apps, the only option will be "Pin to Start", and with some apps: Share and Rate. Here's a picture of the problem:I did already try:Restarting the PC.Doing scannow, DISM, and scannow again.Fixing Registry errors with CCleaner.Updating BIOS and drivers. What can I do to fix the problem?

As it says in the subject: my laptop screen keeps going dark for a second or two while in use (and plugged in). It's not going to sleep or shutting down; any music playing doesn't cut out, and when the black screen goes away I'm still logged in and my programs are all up and running as they were before the flicker. Last night while running on battery, it shut down on 18% power and wouldn't switch back on for almost an hour, even while plugged in. I don't know if that was the start of the problem; the black flicker started happening today. I think it's happened three or four times today. I only bought the computer three months ago and it's definitely not experienced any knocking around or anything.  Can anyone tell me what's wrong and how to fix it?

How was the display connecting it on the external monitor?
Is the display dim even on the BIOS screen?
 
Dim screen in BIOS with external monitor ok isolates the issue to the LCD panel lightning.

Whenever i lean my Yoga 920 at the center (so all the pressure is focused at top-center), instead of the gums at the four corners, my computer screen blacks out until I remove the pressure. It's a really uncommon way to lean the computer, but I was asking myself if this is a worrying problem. Perhaps, by repeatedly pressuring that point when I might keep the laptop on my laps or when I carry it in a bag it could worsen that problem even more.

Hello DennyLarsonThanks for using the Lenovo forums.Sounds like something may have potentially got fried perhaps.
 
Try a static discharge for this, it may help to resolve the issue or at least get rid of any built up static on the motherboard.(If the battery is internal, please just skip the remove/replace battery steps.)1. Turn the unit off2. Remove the battery and the Mains adapter3. Press and hold the front power button for 30 seconds4. Replace the battery and the Mains adapter5. Turn the unit on as normal
 If these steps do not work I would recommend, that you call your local Lenovo support line for a possible service. Below is the link to the phone list where you can find these numbers
 
Hope this helps, let us know how you get on.==================================================================================Did someone help you today? Thank them with a Kudo! If you find a post helpful and it answers your question, please mark it as an "Accepted Solution"!

They said, that I need to wait for evaluation and repair time. I can not afford it financially.Now I looked through many forums, this problem turned out only for me.

Hi guys, My first message here and unfortunately, it's not for the coolest reason.I have a Yoga 500-14 IHW that works perfectly well when plugged, but I noticed a few days ago that as soon as I unplugged it from the USB type power port, the screen suddenly turns black. I thought it was a question of brightness, drivers, windows power plan, etc. I have also tried all the solutions here (https://forums.lenovo.com/t5/forums/v3_1/forumtopicpage/board-id/ll06_en/page/6/thread-id/28087), without success once again.One thing that I noticed and that bothers me a lot is the fact that once it is unplugged, if I try to power on the laptop, the screen is black and no Lenovo spash screen appears. The computer is working, the lights are on, I can hear the fans of the graphics card, but no screen. And of course, as soon as I plug in the power cable, the screen lights up and I'm in front of the Windows login page. If I want to access the BIOS, I can only do so once it is plugged. If I want to start from a live cd, I can only do it once plugged.All of this leads me to think that my laptop screen is broken and no longer works when it is unplugged. Is it a battery problem? The battery is at 100% right now, but is there perhaps a more specific test to be done on the battery?I'm waiting for good ideas to check what else is going on. Otherwise, do you confirm that I will have to return the computer in warranty?Thank you very much,Jed13
