What a Chromebook Is

From the outside, a Chromebook looks like any other laptop. It has a screen, a keyboard, a trackpad and the usual ports.

The difference is the software inside. Instead of Windows or macOS, it runs ChromeOS, which Google designed to be simple and light.

Many brands make Chromebooks, including Acer, ASUS, HP, Lenovo and Samsung. Google sets the software rules, while each brand builds its own hardware.

You will also find Chromebook tablets and desktop boxes, but the laptop is by far the most common form.

How ChromeOS Works

ChromeOS starts in seconds and opens to a simple desktop. A shelf at the bottom holds your apps, much like a taskbar.

You sign in with a Google account. Your bookmarks, settings and Chrome extensions then sync across devices automatically.

Files can live on the laptop itself or in Google Drive. The Files app shows both side by side, so moving things around feels familiar.

Security built in

Each app and web page runs in its own sandbox, which helps keep problems contained. Updates install quietly in the background and apply on the next restart.

Google also says the system checks itself at every startup. If it finds tampering or damage, it usually repairs itself.

Because of this design, most people do not need separate antivirus software on a Chromebook. Still, you should use strong passwords and a password manager.

Several users on one laptop

A Chromebook can hold more than one Google account. Each person gets their own apps, files and settings after signing in.

Guest mode lets a visitor browse without seeing your data. When they sign out, their browsing history is wiped.

What Apps You Can Use

Your main tools on a Chromebook come from three places. Knowing them helps you judge whether one fits your needs.

Web apps

Anything that runs in a browser works on a Chromebook. That includes Gmail, Google Docs, Microsoft 365 on the web, Netflix, Spotify and Canva.

Many web apps can also be installed, so they open in their own window like normal programs.

Android apps

Many Chromebooks can install Android apps from the Google Play Store. You turn this on under Apps in the Settings menu.

Google notes in its Play Store help page that only some Chromebooks support it. Work and school laptops may also block it.

Apps from your phone do not copy over by themselves, so you download them again. A few apps will not run on certain models.

Linux apps

More advanced users can turn on a Linux development environment. It lets you run coding tools and some desktop programs.

Most everyday users will never need it, but it makes Chromebooks more useful for students learning to code.

Using a Chromebook Offline

A common myth says a Chromebook is useless without the internet. In fact, many tasks still work offline.

Google lists several in its guide to working offline on a Chromebook.

• Read, reply to and search Gmail after you turn on offline mail.
• View, create and edit files in Google Docs, Sheets and Slides.
• Edit and write notes in Google Keep, which sync when you reconnect.
• Watch movies and shows you downloaded ahead of time.
• Play offline games from the Play Store or the Chrome Web Store.
• Edit photos with the built-in photo editor.

Set up offline access while you still have a connection. Messages you send offline wait in an outbox and go out once you are back online.

Offline Gmail does not work in Incognito or Guest mode, so use your normal profile.

Updates and the End Date

Every Chromebook has an end date for automatic updates. Google calls it the Auto Update Expiration date.

According to the Auto Update policy, ChromeOS devices receive 10 years of updates from the platform release date. Google lists each model with its end month and year.

The clock starts when the model first comes out, not when you buy it. So an older model on sale may have fewer years left.

What happens after the end date

After that date, the laptop stops getting new features and security fixes. It still turns on and works, but Google will not offer technical support.

Over time, websites and apps may stop working well. For safety, it is wise to replace the device after updates end.

How to check your date

Open Settings, then select About ChromeOS and Additional details. Look for the update schedule line.

If you are shopping, look up the model on the Google policy page before you pay.

Chromebook Plus Explained

In 2023, Google introduced Chromebook Plus, a label for faster models. It sets minimum hardware so buyers know what they will get.

According to Engadget, every Chromebook Plus must meet these minimums at launch.

These models also get extra Google features, including some artificial intelligence tools. Prices for the first models started at about $399.

A basic Chromebook is fine for browsing and homework. Choose a Plus model if you keep many tabs open, join video calls often or edit photos.

Who Should Buy a Chromebook

Great fit

• Students who use Google Classroom and Google Docs
• Families who want a simple, shared laptop
• Older relatives who mainly browse, email and video call
• Anyone on a tight budget who works mostly online

Poor fit

• Serious gamers who want the latest computer games
• Video editors and designers who rely on desktop programs
• Workers whose jobs require Windows-only software

How to Choose a Chromebook

1. Check the update end date on Google’s policy page.
2. Aim for at least 8 gigabytes of memory if you keep many tabs open.
3. Pick at least 64 gigabytes of storage, or 128 for Android apps and offline files.
4. Choose a full high definition screen for sharper text.
5. Look for a battery rated for a full school or work day.
6. Confirm the model supports the Google Play Store if you need Android apps.

Battery life matters a lot on a laptop you carry all day. Our tips to extend laptop battery life work on Chromebooks too.

Setting Up a New Chromebook

Setup takes only a few minutes. Turn it on, connect to Wi-Fi and sign in with your Google account.

Your Chrome bookmarks and extensions appear automatically. Pin your favorite apps to the shelf too. Next, turn on the Play Store if you want Android apps, and set up offline Gmail and Drive.
