Tinkering with your laptop may feel a little nerve-wracking, but upgrading from home is actually a great way to improve performance for less than buying a whole new device. Typically, there are a few things you can upgrade on a PC laptop — RAM, storage, video/sound cards, and Wi-Fi card. If you have an especially modular laptop, you might be able to replace the CPU or motherboard. This wikiHow article describes the general steps to upgrade a PC laptop.

Things You Should Know

  • Get your laptop’s model information and manual before starting an upgrade. This will help your find the correct part and replace it.
  • Follow our safety and setup tips before working on upgrading your laptop.
  • Whether you can upgrade a part often comes down to compatibility and modularity. If a part is soldered in your laptop, it often isn’t user-replaceable.

Safety & Setup

  1. There are a few ways to set up a safe place to perform the upgrade at home. Following safe practices will keep you (and your laptop) safe.
    • Your laptop manual will likely have a safe-handling section. This might be labeled something like “guidelines to working inside your laptop.”
  2. ESD (electrostatic discharge) can damage your laptop and new components. Here are some general ESD tips:
    • Stay away from materials that generate static electricity (e.g. carpets and rugs).
    • Ground yourself by touching a piece of uncoated metal before starting the upgrade.
    • Wear an anti-static wrist strap if you have one available.
    • Keep new components in their ESD-safe packaging until you need them.
    • Use tools that are ESD-safe.
  3. Then, unplug anything connected to the laptop (AC power, mouse, keyboard, headphone, USB sticks).
    • Hold the power key on your keyboard for 5 to 10 seconds to discharge any remaining electricity.
  4. If you have an external, removable battery, detach it from your laptop and set it aside.
  5. If your laptop has an internal battery, don’t puncture, dent, or bend the battery. Damaging the battery may cause it to catch fire or release toxic fumes.
    • Discharging an internal battery below 25% lowers the chance of a fire or toxic fumes in the event of battery damage.
  6. After removing the bottom panel, but before starting an upgrade, unplug the internal battery (if your laptop has one and it's possible to do so). This helps prevent damage to electrical components in your laptop during the upgrade.
    • Internal batteries are often connected to the rest of the computer by a multi-cable plug. However, battery connectors can vary. Refer to your laptop manual for information on disconnecting the battery.

  1. In your laptop manual, look for the section on memory modules.
    • If you can't find the information in the laptop manual, there are tools online that will show you the correct RAM for a specific make and model of laptop. Click here for an example of one of these tools.
    • You can check out our standalone guide on increasing laptop memory for more info.
  2. You can buy the RAM you need in many different places. Once you've identified the specific type of RAM you want to buy, in a search engine, type the specific RAM type, and then choose an online store where you'd like to purchase the RAM.
    • If you're using more than one RAM memory module, you need to make sure that they're each the same size. For example, you can't use a 2 GB RAM module with a 4 GB RAM module. They'll both need to be 2 GB, for example.
  3. Static electricity can destroy computer components. The simplest way to do this is to touch a piece of metal before handling computer components, but there are methods you can use too. [3]
  4. On many laptops, this panel is on the bottom of the laptop case and secured with one or more screws.
    • Your laptop maintenance guide will have very specific instructions on how to do this.
  5. If you're adding RAM to an empty memory slot, you won't need to remove the old RAM first.
  6. This information is at the beginning of this article.
  7. Push the RAM gently, but firmly, into place Do not force the RAM if it isn't going easily. Do not touch the RAM chips—hold the RAM only on the edges of the module.

    • The make and model number is often printed on the bottom of the laptop, but is sometimes also printed above the keyboard on the inside of the laptop.
  2. In a search engine, type the manufacturer, make, and model number of your laptop, and then type manual . Among the search results, you'll find a link to the manual itself or to a page on the laptop manufacturer's website where you can download the manual or maintenance guide.
    • You can also go directly to the manufacturer's website to get your laptop's manual or maintenance guide.
    • If it's available, download the laptop's service and maintenance guide, because it will have detailed information about the specific hardware you can use to upgrade your laptop.
  3. In the user manual or maintenance guide, determine the hard drive models that are compatible with your laptop.
    • In a search engine, search for the specific models of hard drives that are compatible with your laptop.
    • If the hard drive isn't the right physical size, it won't fit in your laptop.
    • Some laptops can replace their hard drive with a solid state drive, a faster type of storage. They tend to cost more than hard drives, but the speed boost might be worth it if opening applications and loading files feels slow on your computer.
  4. Backing up a hard drive can take more time than a laptop battery has charge. If you plug it in, you won't need to worry about how much battery life you have.
  5. Before installing your new hard drive, copy the contents of your laptop's current hard drive to the new one. This will save some time, because you won't have to reinstall all of your applications.
    • On Windows 8, System Image Backup is the program you can use to backup your hard drive. On Windows 7 and earlier, it's called Backup and Restore. [4]
    • On Mac OS X 10.5 or newer, you can use Time Machine to back up your hard drive. You can also use the Disk Utility to back up your hard drive to CD or DVD.
    • If you want to start fresh with your new hard drive, don't backup to the new hard drive. Install your operating system, and then install and copy over any files that you need.
  6. You will need a SATA-to-USB adapter to connect the two hard drives. You can also put the new hard drive into an external hard drive case which will have a USB connection.
  7. Some hard drive manufacturers include their own cloning software, which may already be on your computer. You can also use a third-party application.
    • Clonezilla is a multi-platform, free, open source disk cloning utility. [5]
    • There is a large number of cloning software for all of the major operating systems. [6]
  8. Before cloning the hard drive, be sure to read the help files to make sure you understand the process.
    • The cloning software will check to make sure the new hard drive is large enough to clone the old hard drive to it.
  9. Be sure to unplug and turn off the new hard drive too. Wait at least one minute for the electricity in the laptop to dissipate before continuing.
  10. If the external battery remains in the laptop during the upgrade, it can give you an electric shock. You may also need to remove it to reach the laptop's hard drive.
  11. This information is at the beginning of this article.
  12. As noted above, you may be able to reach the hard drive through the battery compartment. On other laptops, you may have to take off the entire outer case or detach the keyboard. A few laptops offer direct access to the hard drive through an access panel on the bottom.
    • If you're not sure how to get to the hard drive for you laptop, refer to the user manual or maintenance guide for your laptop.
  13. Put the new hard drive in, but do not force it.
  14. If you're starting up with a blank hard drive, you'll need to reinstall your operating system.

    It depends on how much money you have and how old your laptop is. If it's only a year or two old, it's probably worth upgrading some of the components if you want to improve the speed. If you've got a dinosaur on your hands though, it may be worth just replacing it.

    If you don't have a solid-state hard drive, that's probably the best choice. Switching from an old school hard drive to a solid state hard drive is like moving from a golf cart to a race car. If you've already got a solid-state drive, I'd probably look at upgrading your RAM.

    Reinstall your operating system every 18 months or so. A lot of people don't do this, and it's a great way to keep your computer from getting clogged up with junk and old files.

      • While desktop computers usually allow users to select RAM memory and graphics cards from any manufacturer, laptop computers usually require users to obtain upgrade equipment from the laptop's manufacturer.

      • While it is possible to upgrade a laptop in the ways described above, you should not shop for a laptop thinking you can upgrade it later. In most cases, it is more cost-effective to buy a laptop with all the features you need from the start, and perhaps a few more than to buy a lesser machine and upgrade it to the level you want.
        Thanks
