Re: Y70 screen (flashing - blinking)

2015-12-13, 16:55 PM

For me it started just random but I found out it was related to some kinds of moving images and some times just by fast movement. I'm starting to think the ASUS G501JW has the same panel/display because it's having similar issues. Lenovo it not being too helpful, so if they can't help me I'll maybe just change the display/cable/panel myself.

I sent my laptop to customer service today, waiting for investigation response next two days.
Customer agent wrote in problem details (LCD Flickering and lines) he said it's probably LCD screen problem.

How do you contact Lenovo Service for support?  Whenever I click on support or contact, I get a blank page.

 

thanks

Why, thank you very much for the contact info!!

 

Also, about 10-minutes ago, I upgraded to BIOS 9ECN43WW(V3.03), released 10/23/2015.  In the seconds prior to upgrading, my screen flashed every 3-4 seconds.  After upgrade, no flashing.  It's only been about 20 minutes, but it's been like a minor miracle ($1400 miracle).  We'll see...

 

I have a Y50-70 Touch.  I will post again should the flashing start again.

I am sure it is the graphics card, I have the same problem as you 

Screen glitching

 

I am pretty sure its the graphics card, so far it has frozen my installation to windows 10 about 5 times, crashed my computer on reboot when ive tried to update its driver, and displayed to me about 4 months of annoyingly seizuristic display. 

 

I have also done the Lenovo Video Test on my system from the

Lenovo Diagnostic Solutions: Diagnostic Tools 

page, and it found an error saying something like, "a thermal protection mechanism was triggered. Please be sure the ventilation openings are not obstructed". So now i am certain that my graphics cardis behind all the troubles I have had to update to Windows 10.

Hello

i know how to fix it bro ;)
At first I must say that this is a problem combination of software and hardware
Not for graphics cards, drivers, or even operating system or hardware failure
Unfortunately, the problem is CPU usage!!
I can not tell you why, because I do not have enough information engineering
The only solution that I used for a long time, I and my problem completely solved
Changing the maximum use of  CPU  from the battery settings -->100 to 99(best performance and balance)
The problem will be resolved
Good luck

 

note:

i think our cpu is overclocking on 100 usage !!    and its not locked from overclock!

I have still had no problems whatsoever since limiting my max processor state. I have it set at 80% and still get normal framerate on all my games.
