Flex2 issues

I am hopeful someone can provide information on how best to avoid or recover from two issues with my Lenovo Flex2-15.


1) The builtin monitor has a habit of failing to come on when the laptop is powered up. (This behavior started shortly after the warranty expired. I have been living with it for several years) After some period of time has elapsed using an auxiliary monitor to get the laptop  booted, the builtin monitor will suddenly produce a picture (perhaps as much as an hour or more later, perhaps 5 minutes or less), and then remain completely OK through several reboots. Then it will suddenly once again refuse to come on when the machine is booted. I have not been able to determine what causes either the loss of the picture, or its sudden recovery. The picture has never disappeared during actual use. It is simply a failure to come on when powered up.


2) This week, the machine went into sleep mode when power on was attempted from a completely normal shutdown two days earlier.  (Using Windows 10 keyboard Winkey-X;U;U.)  The battery status indicator was unlit, the power button blinking.  Use of the power button was ineffective to either wake the machine or turn it completely off again. I also tried using the "Novo Button", which I had read somewhere might turn off the battery. Nothing I tried would stop the blinking power button.  In desperation mode, I finally managed to turn off the machine only by disconnecting the battery connector, which of course required almost complete disassembly and reassembly of the machine. After doing that, when the battery was reconnected, the machine booted up---but without its monitor (see above).  I therefore believe the two issues are somehow related. Interestingly, the builtin monitor suddenly displayed a picture at the exact moment the Chrome browser displayed the home page of this forum!  (The first thing I will try the next time the builtin monitor does its disappearing act.)


When purchased, the machine ran Windows 8. It was since upgraded to Windows 10 and the hard drive was replaced by an SSD. Windows 10 is updated regularly to the very latest. This past week, I installed Lenovo's maintenance and update software. This software claims that all drivers are up to date, and all hardware components are working correctly. 


I am at wits end. I do not look forward to the prospect of having to disassemble the machine in some hotel room on a trip.  Nor the need to lug around an auxiliary monitor to make a laptop usable. 


Perhaps a registry entry? Some driver setting? Something in the BIOS?  Windows power settings?  (I have tried virtually every combination possible)

Hi Ocahui.


Welcome to the Community Forums!


I really want to help here.


If all of the drivers are up to date and still the issue persist, It's a possible hardware issue, LCD issue, or loose connection.
You may look for trusted local service center in your era for further diagnosis.

To reduce your repair expense's, i will post some links how to replace, the parts that the local service provider found faulty, and a web page to order the necessary parts.
Hope this will address your query.

Re: Flex2 issues

Thanks for the speedy reply. I strongly doubt there is a hardware issue, but thanks for your help.  


I do have a problem update:  On booting up today, the screen was again blank. I used a spare monitor and visited the web page to access the diagnostics engine while the problem existed.  As expected, the display diagnostic reported no issues. 


I then clicked the "Windows Support Center" icon, selected the OS, and ran the display troubeshooter.  To my surprise, it reported back that it had detected a problem and that the solution required a restart.  Upon restarting, to my further surprise, the monitor instantly came on as it rebooted.  


It would be nice to know what was changed.  Possibly a driver.  Hopefully that fix will last. For now, I am a believer in the Lenovo web support tool! 

And we're back...
