What can be done with an old laptop whose screen is cracked?
Use an external monitor: You can connect an external monitor to your laptop using a VGA or HDMI cable to continue using it as a desktop computer.
Repurpose the laptop: If your laptop is still functional apart from the broken screen, you can repurpose it as a home media server, a file server, or a network-attached storage device.
Sell the laptop for parts: You can sell the laptop for parts on online marketplaces like eBay or Craigslist. Some components such as the hard drive, keyboard, or memory can still be salvaged and reused.
