Hello! I’ve owned an HP ProBook 640 for about ten years. About six to eight months ago, its screen broke and it was left unused. Now I need it for university. I bought an adapter—display port/HDMI—and it powers on, but it doesn’t show anything on my TV. Additionally, it’s producing a grinding noise during startup, which lasts as long as the sound is happening.

My questions are:
1. How can I get it to display on my TV? I’m not seeing anything.
2. Should I be concerned about the grinding noise? Please help me.

Thank you in advance. Grinding noise.m4a

The hard drive is failing, and it rarely saves data normally. Probably you damaged the laptop, so consider finding replacements.

The hard drive is definitely failing. If you really need data saved, consider contacting a specialist recovery service. It’s probably time to upgrade to a modern laptop—HDDs are outdated for most devices these days.

I believe your assumption about only adjusting the screen is incorrect. It seems you also modified the HDD settings.

I checked the situation carefully. It looks like the hard drive is also failed. On older Dell machines, there’s a key on the keyboard to change the BIOS to an external screen—this feature doesn’t appear here. But if you remove the internal display (which isn’t helping much), there’s a higher chance it will connect via HDMI or DP for the BIOS.
