I just bought a new Pavilion dv6 (LW272UA#ABC) ten days ago and I've noticed that after the screen turns off due to inactivity, or because I close the lid to let the notebook sleep, two to three horizontal white lines flicker on and off at the top of the screen every few seconds until I restart the computer.
Should I be worried ? Should I ask for a replacement from the store tomorrow or should I wait to see if the problem becomes worse or until HP/NVIDIA release a driver update ?

I have had this same problem, I bought a pavilion dv6-6140us on Aug 4, 2011, it had the horizontal line issue. I exchanged that one on aug 17, 2011 to my local best buy for the same exact laptop. yesterday this new system starting doing the same thing. glad to know im not the only one, any help would be great.
I dont believe the issue is with the graphics card because I have a raedon and constantin has a nvidia. however I have noticed that the problem is more severe when I have something in fullscreen. so maybe it is in the programming, but I feel like its a hardware issue.
Thanks in advance

Same! I ordered a custom dv6z off their website its a dv6z-6100 CTO but the first one had the problem you describe and i thought it was something to do with how it was built because the webcam was not working either. So i had a different one built and now it is having the same problem. Hopefully theyll have a fix for this, i am in school right now so i have to deal with the problem until break, ill send it in to get looked at then. But its weird that you guys too have this problem. I think it must be a probelm with the switchable graphics. But im not sure.

And mine too. I can't bring it in until Christmas either.
It seems to happen more/sooner when watching streaming video (e.g. youtube).

Same problem here. Had to opt for this laptop because John Lewis in Newcastle upon Tyne (UK) would not return mine in time for my departure (Samsung with dif. problems) and exchange it for this DV6. Now it starts doing this and I am in Argentina. If it continues with it, shall I take it to the warranty? Is there any way to overcome this issue?
I will need it for work and would be disastrous if it starts failing then!
Thanks for any help.

I have EXACTLY the same problem on my dv6-6124CA. It only happens after I close the lid or the laptop's display goes black after inactivity. Has anybody found a fix? I got my laptop TODAY and already returned it and exchanged it for the same laptop but both have this problem.

Try disabling the feature that automatically shuts down the display. It's under 'Choose when to turn off the display' in 'Power Options' (easily accessed by clicking on the battery icon in the system tray and selecting 'More power options'.
I posted some more information on this issue in this thread: http://h30434.www3.hp.com/t5/Notebook-Display-and-
It seems to have worked for me (DV6-6124CA), and I am still able to close the lid without it happening. Perfectly acceptable work-around in my opinion, but a permanent and proper solution would be preferable.
Good luck, hope this works for everyone.

Do the lines stay there until you reboot or restart?
Have you run HPSA and looked for driver updates? I would recommend updating the BIOS and video drivers.
Please list what versions you have..

This is my system:
Product NumberLW272UA #ABC
BIOS Version/DateHewlett-Packard F.20, 13/07/2011
NameAMD Radeon HD 6750M / AMD Radeon(TM) HD 6620G
Driverc:\windows\system32\drivers\atikmpag.sys (126.96.36.19995, 293.50 KB (300,544 bytes)
A solution I've found to this issue is to turn off the sleep function. If I close the lid or the screen turns off due to inactivity but the computer doesn't sleep the flickering lines do not appear.

I've got the same problem - had the system about 2 weeks. Ran HPSA, am up to date on everything, including BIOS. Disabled the monitor/sleep setting mentioned above, closed the lid, reopened it and seems to have worked (had to close the lid and reopen it though...simply changing and applying the setting did not change the flicker). Didn't flicker (as much) when running a full-screen app (at this moment I have Firefox running full screen and there's no flicker).
Another curious thing - it does flicker when I hold down a key while typing, or when I'm actively moving a window around (the instant I stop moving a window, the flicker returns)
