I have a problem with my laptop, it's lagging! What should I

Hi everyone, I'm new to this forum. I'm here to get information about my Lenovo laptop, which runs on Windows 10 operating system. I'd like to use it just for word processing and internet browsing, but it seems to lack a lot of power, in my opinion! What do you suggest I do about this? If you need additional information, please don't hesitate to ask. Thanks in advance.
