Problems Upgrading an Old Laptop

[K3-z]

Hi, I am new to the forums.
I have a really old laptop- a Samsung NT300V5A-A16B. I think I got it in like 2011 or so.
It's running a Pentium B950, 8GB of DDR3 ram @1600mhz (originally had 4GB), and a painfully slow HM641JI hard drive.
The laptop was extremely slow, and I mean really! It took 40 minutes to load into Windows and for all the icons to load. Opening a browser took 5 minutes. And if that's not enough, it also overheats.
Since then, I've done a factory reset and cleaned the laptop. It still takes 10 minutes to load Windows, and a minute to open a browser. My parents want to use the laptop, but it is way too slow. I was very sure the hard drive was the problem, so I went ahead and bought a Crucial MX500 250GB SSD.

Now here's a plot twist: The laptop screen is cracked and I cannot access the bios. The bios does not output to the TV via HDMI nor VGA.
Normally I would plug the Windows Installation Media flash drive into the laptop and install Windows that way. But I have no way to boot from the flash drive since I don't have access to the bios. So instead, I used one of my other systems to install Windows onto the SSD. It went perfectly fine.
I took the SSD out of the system and installed it onto the laptop. I booted it up, thinking it'll boot up fine. But no, for some reason the laptop screen turns on for half a second, goes blank for a second, and repeats. I have no clue why.
So instead, I used a Sabrent 2.5" SATA Drive to USB 3.0 Adapter to connect the SSD to the laptop. I see output on the cracked screen, but there is no output on the TV. I tried using HDMI and VGA, with no success.

At this point, I am completely clueless on what to do. Did I do something wrong? What should I do? Is there a way to display the BIOS to the TV? Or will this whole thing not work? I would appreciate any advice. Thank you.

Does the laptop have a key like this?

Typically you would hold the function key and press the key with a symbol similar to that to switch to an external display.

Indeed it does. Unfortunately it didn't do anything.

Could be needing a graphics driver, try installing that into the os and see if maybe that might be the culprit

All laptops are different, but it seems some people have had success either closing the lid just after powering on the laptop or booting into the BIOS and then hitting that button.

Here's a couple of links that may help you out.
