Upgrade old laptop?

I found my mother's old laptop today. It's a Fujitsu-Simens Amilio (she bought it 15-20 years ago). Do you think I could do modern hardware in this old laptop? I was thinking about equipping it with a Ryzen 7 and an RTX?

It looks something like this:

It just doesn't work at the moment.

Ne since you can't change anything, everything is soldered.

In fact, I wouldn't upgrade it - even if it worked.

Depending on what you do, I would buy a new model for 550-850 euro.

But that's not the point. I want to upgrade this laptop because I would find it interesting.

No, you can forget that. The only things that can possibly be exchanged are hard drives, RAM and, quite possibly, the CPU. The GPU (if a dedicated one is available. Since I read Pentium D and because of the age, I assume an IGPU) is soldered. With the CPU, however, you are tied to the age-old socket, which means that any CPU that is really much better than the currently installed one is no longer available. With the RAM you are also limited to the built-in standard (I guess DDR or DDR2). GPU is soldered (if dedicated) and would probably not be able to supply enough power anyway.

You have a free choice of hard drives (except NVME SSDs).

Since you first have to see whether the laptop still works, go to a repair café, there are people who can help you with it or give you tips on how you can use the device in other ways.

There's often advice via email, phone, Skype

If the computer is running, you could try Linux, there are resource-saving distributions. https://www.berlios.de/linux-fuer-alte-rechner/

You can forget to replace something or improve the hardware. You can change the hard drive and possibly the RAM.
