Can I upgrade an old laptop?

[SpaceFox93]

I have a Toshiba Satellite L455 laptop. It's been a great companion for the last decade. It's starting to show its age though.

I'm wondering if I can upgrade some components to extend its life. Here's what I'm wondering:

-The CPU is an Intel Pentium T4400. Would it be possible to upgrade it to an i3?
-RAM is 4gb DDR3, dual channel 800mhz. Could I replace them with dual channel 8gb 1600mhz?
-HDD is 320gb 5400 rpm. Could I replace it with a 2.5 500gb SSD?

My biggest concern with all this is if the motherboard can handle these upgrades. Any insight or experience with this?

What is the full model name of the laptop? I don't think you'll be able to support an i3 but there may be other upgrade options available.
As for the RAM I also need the exact laptop model to know what is compatible. 8GB is usually fine but I'm not sure about the supported RAM speed.

Upgrading to a 2.5" SSD should pose no issue.

The exact model number is L455-S5009. The T4400 CPU only has two cores and it works really hard just to stream 720p video. If it's possible, I figured giving the CPU more cores might help distribute the work load. As for the RAM, this website says it takes only a maximum of 4gb, with 2gb removable.

Upgrading the RAM doesn't seem possible

That CPU fits in a socket so something faster may fit (although not much faster), but given the fact that it's a 10 yr old laptop, with a low max RAM ability and CPU swaps in laptops tend to vary by system, you can spend $100-200 on a newer used laptop and will be in a much better spot with your computer. I like Lenovo T420 and 430 models on the cheaper side of used systems, many are business systems that were maintained pretty well and you can find plenty of them on craigslist and such for not much over 100.

An SSD, and a fresh install of Windows, wouldn't hurt. Windows slows down, with time, and that drive isn't helping you any. Even if the drive doesn't completely fix your issues, you can always use it in another system, later.
