How difficult is it to upgrade parts in a laptop?

Generally Within laptop You cant upgrade Graphics card Or Processor You can incline Only Ram Or hard disk

If you have ever bought a laptop computer and have wondered whether you could upgrade the parts inside of it, the short answer is "maybe." Because laptops are custom-made by their manufacturers, whether you can upgrade the parts inside of them depends largely on whether the manufacturers offer parts upgrades for mart to end-users or whether the parts you want to upgrade are standard parts that dont change regardless of the computer they are installed in.

Typically Upgradeable Laptop Parts
While laptops have a certain number of parts that are custom-made, there are some that aren't and which are usually upgradeable by the end-user. These parts include the hard drive and the RAM (Random Access Memory). Hard drives for laptops come in one standard size (2.5 inches), and you are usually able to access the hard thrust on a laptop by removing a few screws on the bottom of the computer. Once the hard drive is removed, you can replace it with a larger one, reinstall your operating system and utilize the increase in size immediately. You can also replace the RAM in your laptop in a similar manner, though sometimes replacing the RAM requires that you remove the keyboard from the laptop to access it. Adding additional RAM can make your laptop run faster; though, beware of trying to install too much RAM in your laptop, as laptop motherboards can only handle a certain amount. This amount varies depending on the make and model of your computer. Check with your computer manufacturer before attempting to add much RAM to your machine.

Typically Non-Upgradeable Laptop Parts
Among the list of laptop parts that are not usually upgradeable unless the manufacturer has explicitly made them so are video cards, CPUs, sound cards and motherboards. These parts are usually custom-designed so that they fit into their particular laptop chassis, so you can't just go out and purchase a standard part and upgrade them. You would have to contact the manufacturer and attempt to purchase these types of parts for your specific laptop model if you wanted to upgrade them. Video cards are more commonly upgradeable than the other parts, however, especially on high-performance gaming machines where the video cards are physically separate from the motherboard or else of being integrated into it.
