Greetings,
I have a problem with my Elitebook 8460p. My old servant service me since 3 years. We have an good relation with highes and lows. Changed hdd, upgraded rams, monthly cleaning and etc.
Anyway; I have a problem with flickers and blinkings. When i push the start (On/Off) the computer, some strange black lines appear and never gone. The funny part is that the black lines, blinkings/flickers gone crazy when i touch the touchpad. But if i didnt touch the touchpad the black lines comes less.
Things i did;
Checked electrical parts - No electrical leakage (Checked with ohmmeter)
I tried to run with on AC and on Battery - Nothing changed.
I was disabled ambient light sensor - Nothing changed.
I was disabled touchpad - Nothing changed.
Formatted, update the BIOS to latest version, w7 up to date, No unknown device, performed stress test CPU & GPU, performed reassemble & assemble Nothing changed.
My suspicion;
The CPU 😞 Because this computer VGA card integrated with CPU. Changing CPU, maybe fixing all problems.
I want upgrade my computer to i7 and my choice : Intel Core i7 - 2670QM.
My reservation / questions;
Is Intel Core i7 - 2670QM CPU compatible with my QM67 Chipset? If compatible; what i need to do? (BIOS update, or different BIOS version etc.)
I have some information about this situation and my notebook.
Hp Elitebook 8460p series using Hannstar MV6 and my motherboard is same. Non VGA. I'm worry about the my solution. If i'm wrong; i spend my money for nothing.
I'm waiting ur answers.
Thank you.

I am so grateful for this thread and your last post Lalit55. I had the same problem when scrolling using left click and touchpad - the screen would go beserk for increasingly long periods.
I didn't install anything new. I just set the refresh rate to 40 Htz as you stated and it has solved the problem for me. Thank you!
