We have had the sheild placed on several laptops and it seemed to fix the issue for several weeks but the blinking came back. Very frustrating! This is only happening on 840 and 850 G3's. We have a mix of 840 and 850 G1's, G2's and G3's but anain only happening on G3's. At first we though it was only happening on those that had HP E232 EliteDisplay monitors but we have seen this on non HP's just not as frequently. I personally have an 850 G3 with HP E232 monitors ... it has the shield and still blinks from time to time and when it does, it is really bad. I have found that I can firmly hold the slimdock and make sure my laptop is firmly seated and the blinking stops. I would appreciate it if someone can try this as well and provide some feedback ... sometimes you can unlatch and relatch the slimdock and that will work as well. Let me know if this works for anyone.

Has HP declaired that as official? I would like to hear from some of the others that have had the "shield" replaced to find out if that completely corrected the flickering issue for them. It seemed to work for us for a short time.

stragne thing that all HP now has to say - update graphic driver, bios and slim 2013 firmware - SP75855, SP78116, SP78255, hoping that it will work :). it didnt. next step - they want me to bring it to service senter for testing. it will take a while.... i will keep you posted. funny... some messages about flickering screen go back to 2012.... 2012. ... it is 2017. and they still make units with same problem. what are they hoping for..

i have hs3110+ mobile broadband installed. to support the solution with shielding, i removed sim card from module. so far so good. it looks like it is shielding after all, and all those software fixes are not working.
