L380 YOGA Display Blink

2018-04-08, 20:56 PM

I have just received 3 days ago my Thinkpad L380 Yoga and the display blinks regularly since out of the box. It goes blank for half a second, is quite anoying being a brand new product. Is this an anomaly (defect) or something in all units to be fixed by LENOVO? Just to know if ask for a replacement or just wait for a BIOS update.

Well, I got mine recently and nothing blinks so I'd say defect. Probably worth contacting Lenovo.

Hi,

 

I have this computer since a month, I am faced to the same problem. Screen flickers especially when I used a game on it. For me it's black and not white though. This is not the only issue I have unfortunately, I also have an issue with left USB port. I am going to open a new thread about it.

Strangely mine stop blonlinb, not sure the reason, installed few window updates but I thought were security updates. Also I changed almost all apps to not resize according Windows settings. Who knows. What's the USB issue about? Is one of the usb-c?

OK, I thought about the problem. This is just an assumption, my screen flickers when I plug my Logitech mouse dongle on the left port (yet this USB port). So I guess this port shares the I/O of the USB-C. Might be a wrong instruction sent from the driver to Window that is thinking the USB device is a screen even if it's not plugged to USB-C port...

To verify my theory I went in the BIOS and switched the shared screen priority from USB-C to HDMI.

Now I plugged the mouse dongle on left USB port, for the moment I don't have flickering anymore.
I am testing the theory and I will let you know if it's resolved.

Ok,

 

Here is my feedback. The solution above did not resolve the problem. I checked the Event viewer and found the warning: "The driver \Driver\WUDFRd failed to load for the device USB\VID_06CB&PID_00A2\82b8988605c8." of Kernel-PnP (EventID 219)

It seems to be a driver problem, I uninstalled all USB controllers from device manager then I reinstalled them. I hope this defenitively resolved the problem. Since I did this I don't have any warning shown in the Event Viewer even screen flickering.
 
Wait and see

Hi guys, I'm also having this issue with these laptops. Got like 70 of these laptops for school and projectors flicker when using HDMI and left USB port at the same time.

 

No solutions so far in this issue.
