Hard to tell without knowing specifications of your laptop. Could you share it, especially how much RAM and what type of disk (HDD or SSD) your laptop have?

I see two problems there. First, you have only 4GB RAM. This isn't enough for casual usage. You'll need to increase installed RAM to at least 8GB. Your laptop have only single SO-DIMM slot, so you have to replace currently installed module. Following 8GB modules are officially supported:
- Samsung M471A1K43CB1-CRC,
- SK Hynix HMA81GS6AFR8N-UH,
- RAMAXEL RMSA3260MB78HAF-2400,
- RAMAXEL RMSA3260MH78HAF-2666,
- Micron MTA8ATF1G64HZ-2G6H1,
- Micron MTA8ATF1G64HZ-2G3B1.
You may also check other brands like Crucial. Just make sure, that they're either DDR4-2133MHz or DDR4-2400MHz.
The second issue is a HDD. To put it simple, when system have insufficient RAM capacity, it starts to use a disk to compensate. HDDs are simply slow to today's standards and when we add this compensation, everything will became slow. Upgrading RAM may not be enough to see true performance boost. You'll need to buy an M.2 2280 NVMe SSD disk and then install OS on it. Then you'll see a real difference. Regarding disk model, Samsung 970 EVO is usually a solid choice.
