A laptop's value depreciates by around 30% each year, so it's not worth repairing if the cost is more than 25% of the original. If your laptop screen is broken or not showing up, you may need to replace it. The cost of repair depends on the type, size, and resolution of the screen. Hard drives can be repaired or replaced, and software problems can usually be resolved with an update or reinstallation.
Before you go to a repair service, consider the cost, quality of the laptop, and waiting period. It's possible to replace the screen yourself, but laptops have different levels of difficulty. If the cost is more than 50% of the laptop's value, you should think about replacing it. Parts may need to be ordered from abroad, so waiting times can be long.
