Lenovo Flex 4 - No display

Q: Lenovo Flex 4 - No display

The display on my Lenovo flex 4 isn't working. It boots up fine. When I add a second screen though HDMI, the display appears on the second screen but not the flex screen. I've checked the screen share settings and it's on the duplicate screen setting. Also the brightness is turned up. The really strange thing (to me) is that the touch screen even works perfectly fine. When I touch it I see the response on the second screen.I've tried restarting, holding down the power button for 20 secs, and updating some drivers.I can make do with the second screen for now but any help would be greatly appreciated!! Don't have money for a repair at the time.

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.)

After reading some things and further inspection, the screen actually does work. There is just no backlight!! Holding up a flashlight at a very particular angle allowed me to see my screen. Is there anyway to fix the backlight?

HI,So I got a Flex 2 15 for Christmas 2014, after about a year the display would sometimes flicker with a red tint and the image would look like it had burn-in. If I closed the lid and opened it back it would go away.Last week the same thing happened but this time its permanent. My display is stuck with this red tint and screen burn in.I tried support but as my luck would have it its out of warranty. I youtubed how to do a disassembly to get to the LCD connector to see if it was a loose connector but it wasn't. Is there any fix for this short of replacing it?Any help would be appreciated.Thanks. Attached is a photo of what I'm experiencing.

Hi All, Need some help regarding my flex 5 laptop. Got it 3 days from a deal from a retailer, laptop has everything I want except the display. The colors of the display are very much faded/washed out even on 100% brightness. faint blue looks gray, blue looks like teal. Quite annoying. I compared the screens with my old laptop ( T410) and there is a big difference in the colors. Is it due to the hardware or because of some windows/lenovo settings? Below are some of the details of the PC: Flex 5-1470 (Type 81C9) Laptop (Lenovo) Machine Model : 81C9000EUS 2GB NVIDIA GeForce 940MX Graphics Intel Core? i5-8250U Processor 14" Touchscreen LED-backlit IPS FHD (1920 x 1080) Display Any help will be appreciated.

Since I started my laptop shortly ago, the display has such a red cast which isn't a problem of the software settings.Also, whenever I am opening or closing an application the old one is fading out slowly while the other one is fading in at the same time. Some aspects of these applications are then still overlapping for a long time or not disappearing at all.(Information about my laptop:    Lenovo Flex 2 Pro-15    I bought it almost 3 years ago    I didn't download anything or change any settings any time near the start of this red cast) Does anyone help?Thanks in advance!Thomas

Hi, I recently purchased a refurb Lenovo Flex 3 1480 model and I am starting to see problems with the display that others have noted on here.  It sometimes flickers on and off and occassionally completely turns off and will not come back on without a restart.   So in troubleshooting this issue I have upgraded my BIOS to version DCN32WW from DCN28WW.  This was more difficult than it sounds because for some reason the PC identified the older DCN28WW as the newer firmware.  I had to override the setting in the BIOS to allow it to install the "older"firmware DCN32WW.  Made no sense. The latest thing I am trying to do is update the Intel VGA 520 display driver to the latest version published on 7/16/16 ver. 20.19.15.4454.  I downloaded the installer from the Flex 3 1480 section of the suppport site. When I try to install it, however, it tells me it is not compatible with my device.  I have tried uninstalling the driver and then installing the newest one and it still won't install.  The driver currently on my machine is 20.19.15.4364.  Can someone explain why I cannot get the newest display driver to install on my laptop?

My LENOVO FLEX 2 14" - model type :80FJJCT0My laptop display doesn't show any picture.Remains dark.  When the Laptop is connected through HDMI port to external TV , display apprears there.  How can i fix the labtop LCD display screen or labtop?.

A:LENOVO Flex 2 14" - screen remains dark - When external LCD connected through HMDI , display shows.

Hi RDATA34 , 
 
Welcome to the Community Forums. 
 
Try to access the BIOS by turning off the system and using the novo button (item 7 page 68) to turn on.
This should offer the Novo menu screen and operates outside windows. 
Pressing caps lock on and off would likewise respond and connecting to an external would produce display.
Such condition isolates the LCD as point of failure. 
 
You can reseat (unplug and replug the LCD cable page 60) or have the LCD panel tested with available service center to verify the integrity of the LCD unit itself.
 
Hope this help answer your query. 
Update us how it goes.
 
Regards

So I have a Lenovo Flex 5 and a Lenovo Active Pen and the touchscreen works great with it. When I use writeIt by Lenovo, the pen has pressure sensitivity, but when I use any other software, I can't use that feature, and it is a pretty important one. Specifically, I need to use it with GIMP.

Hey guys, first time here and I just want to inform you that I'm not a genius so please talk like you're talking to a 9years old kid..

So my problem is as the title says.. Well it started when I opened my laptop from sleep mode then it was hanging up and then it suddenly turned blue with sad face.. I didn't read the problem clearly but i remember it saying a problem about "kernel_????_????"..

I tried to hard reset my laptop cause it was taking so much time then it ended up stuck on the logo... Now I'm the one with the blue sad face...



Hope you guys can help me as soon as possible., thanks in advance..

Right, you mentioned it turned blue with a sad face, that is a Blue Screen of Death (or proper term is Kernel bugcheck) which indicates something has gone wrong.

Problem: Press power button, turns on and no display. Press power button to turn off then press to turn on, doesn't turn on but power button light is flashing. Plug in the charger and turn the Flex 10 off and on again, still not on. Tapping the keyboard, touchpad hoping something happens, no. Give it a couple more seconds then it turns on. Lenovo loading sign comes up then goes to blue screen saying "collecting data because there was an error then will restart for you", restarts. "There was an error with loading Windows. Given two options; option 1: Choose a recovery setting or option 2: restart". Both options have been clicked before and nothing has happened. This time tried choosing option 1 again and the screen starts flickering and Flex 10 turns off. Flex 10 has been opened from the back to check if memory, HDD and all else is correctly in place.  Any solutions? Could the battery be the problem?Is it worth replacing it altogether? Thanks,Scott

I have a Flex 3 (1130). I have a issue with the blinking black screen.  I contacted Lenovo about a month/month and half ago intially and they suggested to download a chipset driver and a bios driver. Did both, didn't help. Updated other drivers, microsoft and windows updates (didn't help). I contacted Lenovo again then sent it into get repaired at one of their facilities. Got it back yesterday (05/23/17) and it is still having the same issues.

I purchased a Flex 3 a little over a year ago. I was having problems initially with the display not waking up from sleep and one of the potential solutions was to install and use the Intel HD Graphics 520 Display Driver instead of the one that came with the machine. That, somewhat, solved the problem but then the Windows 10 Anniversary update that came in 2016 solved this problem.... but a new one has come up as of late.  It seems at times my touch-screen will not work, and takes a reboot to get it to work again. It's usually like 50/50 if it works or not. Also, I've seen a problem where I will be watching videos and when moving the mouse around, it causes the video/sound to lag and freeze up for a second. This sometimes even leads to Blue Screen of Death, and I think the reason is because of the display driver, but I cannot put my finger on it. There is no way to really roll back to the stock driver, and I even tried resetting my machine with no avail.  Anyone have this issue before, or know any potential way to solve it?

Hello. Thank you for taking the time to read this.I got a Lenovo Flex 2 15 a while ago. Over these three months I've tried to find information wether this laptop supports a stylus to draw with to begin with, and which models would those be.After searching in forums, sent pms to Lenovo support via Facebook and being utterly ignored, contacting support of styluses makers (Adonit for example) I always get the same copy pasted get X stylus for Ipad and X for *other lenovo models, like Yoga700, etc* which do not seem to list my model among them. Perhaps it is because of the year or because Lenovo Flex 2 is not being made anymore, which I noticed after getting it, sadly. So I ask once again... perhaps this time someone will know! Does the Lenovo Flex 2 15 support Wacom or any other brand styluses to draw on the screen with? If so, which is the model I should go for? Thank you again for any answer that you could provide.

A:Stylus for Lenovo Flex 2 15

It doesn't support Wacom digitizers, but you can get a capacitive stylus and that'll work.

Past week i received my Flex 5 14", first impressions was awesome - fast, good LCD, compact. But after few hours of use, all of my impressions was broken by fan noise - mine Acer Aspire Nitro, under 60-80% percent load CPU,  wasn't loud  a half of Lenovo is under 20% of CPU use. Fan isn't works correct at all, and, how can i see - issue is mass, many people wrote this or other forums with same issue. 
 
Only fix, i've found is undervolting CPU to 85% by Windows power management. Is that solution? Don't think.
 
When this issue will be fixed? Want to see official comments from Lenovo.

I have free slot avaialable. I have found in the manuals that it can handle only 1600 mhz speed. I am not sure which brand I am supposed to buy.. I have found Crucial RAM 8GB DDR3 1600 MT/s CL11 SODIMM 204pin and judging on informations from my system info software it is compatible with my system.  What do you think? 

A:Which RAM brand for Lenovo Flex 2 15?

Hi LeiceQ,
 
Welcome to the Community Forums.
 
The hardware manual for your system does have ram listing of OEM certified ram.
In cases when you need to get third party ram for upgrade, just make sure that it shares the same specification (DDR3L low voltage(1333MHz/1600MHz) SODIMM 2) and review return options.
 
This discussion would further answer your query on your planned upgrade.

Not sure whats going on with the website, I entered in my serial number to make sure I was getting the specific drivers.  But nearly all the pieces of hardware have two different drivers. I havent had to download any yet so far since I havent done too much.  But, when it came down to video card drivers it listed Nvidia drivers and when I tried to install it it said that the compatible hardware was not found. Shouldnt there be only one driver? I mean.. maybe multiple versions, but they are listed completely different so I would believe they are different drivers completely.

I've seen a few times where I have not used my Lenovo for a several minutes it will go into "sleep mode" and I have to hit the power button to open it again. But it is asking me to sign in. I have to turn it off by holding the power button and then turn it back on. And then it will start showing my normal desktop. How can I stop that "sign in" from showing? I never created a password and didn't think I need to do that.
Can anyone help?

In Sign In Options it has "Password.... Your account doesn't have a password. You must add a password before you can use the other sign-in options."
Whatever that means???? I never created a password and don't understand why it is asking me to "Sign In" when I turn in on from the Sleep mode.

They looked up the serial number and was able to correctly identify the computer, but could not find the part number for the battery. They then transfer me to Geek Squad for some reason. I did see a few battery on sale at Amazon, but they appear to be greatly smaller in capacity (2200 instead of 3560 ma).

It should get you to a bios settings
   Go to the Configuration tab and look for the "Hotkey Mode" option Toggle that to Disable the hit F10 or Fn+F10 to save and Exit
 
It should switch the use of F keys to legacy

I have a lenovo Flex 2 laptop that has been fantastic so far. However, the other day when I shut it down and restarted it, the computer seems to be stuck in a cycle and was unable to boot. I would push the power butto,n the keyboard lights would turn on for a brief moment, the fan would spin and then it would stop. It would try to boot for about 5 seconds and recycle over and over and over. Eventually, the computer would boot. I bought a new battery thinking that was the issue. I replaced the battery, and the problem persists. Well, last night the computer got stuck in the boot cycle but will not turn on anymore. The battery seems to be able to hold a charge when it was on. However, I noticed that if I unplug the battery and plug in the AC adapter, the indicator light that shows that the AC adapter is plugged in will not turn on without the battery connected. This may not have a bad AC adapter? Is my mother board the major issue? What is the next step for me in this stage? Thanks for all the help and advance!

Does anyone have a Lenovo - Flex 4 1470? (Win10/64bit) I bought mine in July 2016 and yesterday when I signed on I got a pop-up from Lenovo telling me about a "critical" Lenovo update. I am pretty sure if was referring to BIOS update = v.0vcn.22ww / 120 MB.
I clicked for it to install and then another pop-up saying something about it (possibly) changing binaries, etc. I didn't know what that was all about and so I cancelled the downlod.
Today I phoned Lenovo and spoke to a woman who said "they" didn't recommend downloading/installing updates to BIOS unless I was having problem with this laptop.
As I asked, does anyone else have a Lenovo Flex 4.1470? If so, did you get this critical update notice and if you did, did you install it?
I am 81 years old and know nothing about these things and wonder if I should just forget about downloading the BIOS update? Or whether it MUST be downloaded for this Lenovo to operate properly.
Thanks for any help.
