Tips: Backup important files in case of wrong deletion
Freeing up space is a common way to speed up an old laptop. To avoid deleting something important wrongly, backup your files before starting any action by connecting an external hard drive or USB to your laptop. And manually copy and paste contents.
How to Free Up Space to Speed Up Old Laptop
The first and very easy thing to speed up your old laptop is to free up your computer space. When space is critically low, an old laptop will often get stuck in a loop, which causes a sluggish PC.

How to Improve Hardware to Speed Up Old Laptops?
Replace HDD with SSD for Faster Laptop Performance
Hard Disk Drive (HDD) is a traditional, non-volatile data storage device. Solid State Drive (SSD) is a storage device that uses flash memory to read and write data. Compared with HDD, SSD is faster, quieter and more durable.
How to check your laptop’s type of storage drive? Go to Task Manager > Performance. Click on Disk and the type shows SSD or HDD.

To change HDD to SSD, you need to buy an SSD first and let professionals replace HDD with it.
Upgrade RAM to Speed Up Laptop
Slowdown is obvious when the memory is very high and your system lacks RAM. Upgrading RAM helps to accelerate your laptop speed and reduce freezing, especially when you want to use video editing software and play games.
If your laptop has two slots and one of them is used, you can add a new RAM stick. If two of them are used, you need to replace the current sticks with higher-capacity ones.
To buy a RAM, you need to pay attention to some specifications: see what your motherboard can handle by searching the web using your exact laptop model; purchase the correct generation as they are not interchangeable (laptops usually use smaller SODIMM sticks); to add one on a vacant slot, match the speed and voltage with the older one.
The ideal combination only for reference: a 512GB or 1TB SSD paired with a total of 8GB or 16GB of RAM.
