Re: HP lap top screen white dotted flickering lines

I have now managed to restart the computer without wiping all my files - eventually I found one of the options that allowed me to "reboot" which then seemed to do the trick and get the PC switched back on again properly.  However the flickering is still reappearing again so updating Bios has not worked.   I am reluctant to try and of the other updates you mentioned as I will not be able to tolerate being locked out of my computer again.  I think I shall probably just have to take the lap top back to the shop and claim a refund and start all over again with a Lenovo or something. It is a pity though as in all other respects the lap top is great and fills an important gap in the market that has been left after Lenovo stopped making a 15" touchscreen 2 in 1 laptop.


But yes your HP team are welcome to contact me and try and help if they can - as I will not be able to get the defective machine back to the shop until sometime next week.

Re: HP lap top screen white dotted flickering lines



Yes I did fix it after HP called me on the telephone.   Bizarrely, it turned out that it was a software issue after all (I had assumed it was hardware).  I would say first check if it appears on a separate monitor (e.g. by plugging in to a TV screen or separate monitor), and if you can, see if it appears when you are in "BIOS" mode if you are able to access that (which is not straightforward at all).  Anyway, the solution for me was to reload the operating software from scratch.  This is what the HP guys are saying in the posts above and indeed the most recent one below.  The problem is that unless you are an IT wizard that can understand all the jargon this is not at all straightforward - when I tried it I became completely shut out from my computer for a few days which was a nightmare until I actually got them on the phone to talk me through it.  So I would say get them on the phone before trying anything too dramatic unless you really know your way around these things.  Personally I did not even know what "BIOS" was until this happened and I find many of the technical posts on these forums quite difficult to understand.   I see you have already had HP on the phone though so it may be a different problem for you.  I did not have the screen "jumping around" as you describe...


Good luck anyway and you have my sympathy,

Re: HP lap top screen white dotted flickering lines


Thank you for replying with this overwhelming and detailed response Smiley Wink 

I appreciate your time and efforts,


You haven't clarified if the screen jumps while you are in the BIOS screen as well,

Please restart the computer, tap on F10 during the restart and when you get to the BIOS interface, stay there and wait for the amount of time it normally takes to jump around with the dots, etc...and reply back with the details of what happen during your time in the BIOS interface...As mentioned by the previous tech, if it happens in the BIOS - it's a hardware failure.


If it doesn't do it in BIOS, it's most likely a software issue and we may need to reinstall the windows as the last resort,

Alternatively, you may also try the steps mentioned by our expert @Axilotl as well.


Keep me posted, 

If the information I've provided was helpful, 

give us some reinforcement by clicking the solution and kudos buttons, 

that'll help us and others see that we've got the answers! 

Good Luck.
