Ram issue.
Ram issue.
Consider bringing the stick to a repair shop and have them test it. This will help confirm whether it needs further verification. Manufacturers typically supply a specifications sheet for this purpose, such as "HP [laptop model] RAM support details."
I'm a bit delayed in sharing this, but I wanted to post a quick solution. On my profile there was another laptop where the display wasn't working temporarily. For this one, the fix came from using the right sticks. When I turned on the computer with both the new and original sticks, I heard three long beeps followed by two short ones—this signaled a memory hardware issue. But it wasn't a hardware problem; the BIOS didn't know what to do. I held down the Win Key, B, which actually corrupted the BIOS and triggered HP Bios Recovery. After that, everything worked properly and quickly now.
In this forum we permit only one subject per issue. I recognize you have several concerns about the single device, and the most effective approach would have been to submit a single topic in the troubleshooting area with your problems listed so they could be addressed more efficiently. This is just a note for now. At the moment, the existing topics will remain separate rather than being merged. Please keep this in mind when posting in the future.
