Powerwash vs Recovery on Chromebooks: What Is Different?

The short version

Powerwash and recovery are both ways to reset a Chromebook, but they work at different levels. A Powerwash is a software reset you can start from ChromeOS itself. It is the better first choice if your Chromebook still turns on and you want to clear a persistent software problem. According to Google's Chromebook update help, a reset can be done without deleting your personal files.

A recovery is a more complete reinstall of ChromeOS. Google's help is clear that recovery permanently erases everything on the hard drive, even your downloaded files. Use recovery when ChromeOS is missing, damaged, or your device will not start normally. Before you recover a Chromebook, back up anything you want to keep.

What is a Powerwash?

A Powerwash is a factory-style reset for ChromeOS. You launch it from the Chromebook itself, usually from Settings under About ChromeOS. It is designed to clear the kind of software problems that build up after installing many apps, changing settings, or using an older device for a long time.

Google's Chromebook help lists a reset as one of the steps to try when a system update does not download. The same page says a reset can be done without deleting your personal files. For a working Chromebook, that makes Powerwash the less disruptive option. If the reset does not fix the problem, the next step is recovery.

• Use Powerwash when ChromeOS still starts and you can reach Settings.
• Use Powerwash when you want a clean software state before passing the device to someone else.
• Use Powerwash after you have tried restarting and checking your internet connection for an update problem.

What is a recovery?

A recovery puts ChromeOS back on the device from separate recovery media. It is the most complete way to repair a Chromebook whose operating system has become damaged or will not load. Google's Chromebook help warns that recovery permanently erases everything on the hard drive, even downloaded files. Because of that, recovery is not the first tool you should reach for unless the device will not start.

ChromeOS also has a startup self-check. Google's Auto Update policy says that every time a Chromebook starts up, it checks whether the system has been tampered with or corrupted. If it finds a problem, it usually repairs itself by reverting to its original state. Recovery is the fallback for cases where that self-check cannot bring the system back.

If you need to create recovery media, follow the steps in create Chromebook recovery media. If the recovery process itself fails, see recovery mode is not working.

• Use recovery when the Chromebook will not start normally.
• Use recovery when ChromeOS is missing or damaged.
• Use recovery when a Powerwash did not fix the problem and updates still fail.

Powerwash and recovery compared

The main difference is scope. Powerwash resets ChromeOS from within the system. Recovery reinstalls ChromeOS from scratch. The table below summarizes what that means for your files and for the repair process.

How to decide between Powerwash and recovery

Start with the least disruptive option. If your Chromebook starts and you can open Settings, try a Powerwash. Google's update troubleshooting page walks through restarting, turning the device off and on, checking your network, and then resetting before moving to recovery. A Powerwash can clear the kind of software issue that makes ChromeOS slow, unresponsive, or stuck on an update.

If the device will not start, ChromeOS is missing or damaged, or a reset did not help, choose recovery. You will need to prepare recovery media before you begin. If the Chromebook shows an error such as ChromeOS is missing or damaged, recovery is usually the way to put ChromeOS back. See the guide for ChromeOS is missing or damaged for more detail.

After a recovery, the device is on a fresh copy of ChromeOS. If the Chromebook is still within its update support window, it will check for updates when it connects to the internet. For a device that is very old, a recovery will not add years of new features; it restores the operating system the device can still run.

• Can the Chromebook start and reach Settings? Start with Powerwash.
• Does the Chromebook show a damaged OS message or fail to start? Go to recovery.
• Did Powerwash finish but the problem remains? Move to recovery.

Back up before you reset

Even though a Powerwash can be done without deleting personal files, back up anything you would not want to lose. Software resets can change which apps are installed and which settings are active. For recovery, backup is not optional because recovery erases everything. Use cloud storage for documents and keep important files somewhere you can reach after the reset. The guide on backing up files on a Chromebook covers your options.

If you use Linux on your Chromebook, include the Linux environment in your backup plan. Google's Chromebook help describes separate backup and restore steps for Linux files and apps. Since recovery erases the drive, any Linux tools, files, and containers will be lost unless you saved them separately. See back up your Linux files and apps before resetting.

• Copy documents, photos, and downloads to cloud storage or another device.
• Save any local files you need before starting recovery.
• If you use Linux, back up its files and apps separately.

Managed Chromebooks and older models

If your Chromebook is managed by a school or employer, check with your administrator before resetting. Google's Chromebook help says that if you use your Chromebook at work or school and cannot update it, you should contact your administrator. Managed devices can have policies that control updates, resets, remote wipe, and re-enrollment. ChromeOS for business explains that administrators can remotely wipe a lost device and force re-enrollment, so following your organization's process is important. See the best business Chromebooks guide if you are choosing managed devices for a fleet.

Older Chromebooks eventually stop receiving new software updates when the hardware can no longer support the latest ChromeOS. Google's help says you can continue using the computer, but you may see a message suggesting that you consider upgrading. A recovery can reinstall the current operating system, but it will not make a device receive updates beyond its supported period. Check your device's update schedule in Settings under About ChromeOS, or use the guide on Chromebook updates and support to understand what to expect.

After a reset

After a Powerwash or recovery, sign in again and let ChromeOS check for updates. Your Chromebook automatically checks for updates whenever it connects to the internet. That means a freshly recovered device can quickly get back to a current, secure state if the model is still supported.

ChromeOS is designed with security features that make the reset meaningful. Google's ChromeOS product page describes verification at boot, a read-only operating system that blocks executables, data encryption, and sandboxing. A full recovery is therefore both a repair and a security reset. If the device will be passed to another person, this is the cleanest point to hand it over or to use the guide for migrating to a new Chromebook.

Questions

What is the main difference between Powerwash and recovery?

A Powerwash is a software reset you start from ChromeOS settings. A recovery reinstalls ChromeOS from separate recovery media. Google's help says a reset can be done without deleting personal files, while recovery permanently erases everything on the hard drive.

Does Powerwash delete my personal files?

Google's Chromebook help says a reset can be done without deleting personal files. Still, back up important files before resetting because a reset changes apps and settings, and a recovery erases everything.

Does recovery erase downloaded files?

Yes. Chromebook Help says recovery permanently erases everything on the hard drive, even downloaded files. Back up your files before you recover.

Should I use Powerwash before recovery?

In most cases, yes. Google's update troubleshooting page suggests trying basic steps, then a reset, before recovery. If ChromeOS will not start at all, go straight to recovery.

Do I need special media for a Powerwash?

No. A Powerwash is started from ChromeOS itself. A recovery is a separate reinstall procedure that uses recovery media, so follow the recovery preparation steps before you begin.

Can I recover an old Chromebook that no longer receives updates?

You can continue using it, but it will not receive new software updates. Google's help says older Chromebooks eventually stop receiving updates, and you may want to consider upgrading after that point.
