Like driving a car until it breaks down, it can be tempting to use your notebook until it no longer functions. But if your computer is turning into an old banger, it may be time to go ahead and replace it with something better.

Performance. If your notebook is working slowly, then so are you; buying a notebook with increased RAM and a faster processor will prevent your lightweight machine from turning into a burden. Also, look for a notebook that can access essential documents, like your calendar and contact list, without booting the operating system, saving you time when it matters most.

Style. You wouldn’t make a presentation in a patched suit, so why would you show up with a notebook in need of repair? Fair or not, every part of you is on display when you are making a pitch, and the notebook you show up with is part of the package. Replacing a scuffed up notebook for one designed with professionals in mind will make the impression you want.

Security. Anti-virus software and a firewall is fine for preventing random attacks, but if a dedicated attacker is trying to steal your intellectual property they may not be enough. Upgrading to a notebook with drive encryption and a file sanitizer will keep your data safe from snoopers. For even better security, consider a notebook that uses biometrics, such as facial recognition through the built-in webcam, to restrict access.

Cost. Notebooks that are designed for businesspeople don’t have to be expensive. Some manufacturers lower the price by cutting back on features that aren’t important in business. Opt for a notebook that meets your needs and let the gamers pay a premium for that high-end graphics card. Sometimes you can save money with a new notebook. For example, can you trade in your old notebook and get a minimum trade-in value?
