HP Elitebook 8460p screen flicker & blinks issue and upgrade help.

[burakor]

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.

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!
