What a factory reset does and when you need one

A factory reset wipes your Lenovo tablet back to the state it left the factory—all your apps, photos, files, and settings disappear. The operating system stays the same (Android or Windows, depending on your model), but everything you added or changed is gone. You should only do this when the tablet is freezing constantly, running so slowly it is unusable, infected with malware, or when you are selling or giving it away.

Before you reset, back up anything you want to keep. Photos, documents, and app data can be recovered if they are stored in cloud services like Google Drive, OneDrive, or Lenovo's own cloud backup, but anything stored only on the device itself will be lost.

Key Takeaways

  • A factory reset erases all apps, files, and settings but keeps the operating system; back up your data first through Google Drive, OneDrive, or cloud backup.
  • On Android Lenovo tablets, go to Settings > System > Reset options > Erase all data and tap the confirmation button.
  • On Windows Lenovo tablets, go to Settings > System > Recovery > Reset this PC and choose whether to keep or remove files.
  • The reset process takes 10 to 30 minutes depending on how much data is on the device; do not turn off the tablet during the reset.
  • After the reset completes, you will see the initial setup screen as if the tablet is brand new, and you can sign back into your accounts.

How to reset an Android Lenovo tablet

Open the Settings app—usually a gear icon on your home screen or in the app drawer. Scroll down and tap System (on some older Lenovo tablets this may be labeled About tablet or About device). Look for Reset options or Reset.

Tap Erase all data or Factory reset. The tablet will ask you to confirm—read the warning, which will tell you what will be deleted. Tap the button to confirm (usually labeled Erase all data or Reset device). The tablet will restart and begin the reset process. This usually takes 10 to 20 minutes. Do not turn off the tablet or remove the battery during this time.

When the reset finishes, you will see the initial setup screen, the same one you saw when the tablet was new. You can now sign in with your Google account or Lenovo account to restore apps and settings that were backed up to the cloud.

How to reset a Windows Lenovo tablet

Open Settings (usually the gear icon in the Start menu or taskbar). Click System on the left side, then scroll down and click Recovery. Under Reset this PC, click the Reset button.

Windows will ask whether you want to Keep my files or Remove everything. Choose Remove everything for a true factory reset. Windows will then ask whether to remove files locally or cloud-based—for a complete wipe, choose Local reinstall. Confirm your choice, and Windows will restart and begin the reset. This usually takes 20 to 30 minutes.

When the reset finishes, you will see the Windows setup screen. You can sign in with your Microsoft account to restore apps and files from OneDrive and the Microsoft Store.

Backing up your data before you reset

On an Android Lenovo tablet, open Settings and tap Google (or Accounts). Tap your Google account, then tap Account services and Manage your Google Account. Go to the Data & Privacy tab and make sure Google Drive is turned on for photos and documents. You can also manually upload files to Google Drive by opening the Drive app and tapping the plus icon to upload.

On a Windows Lenovo tablet, open Settings, click Accounts, then Sync your settings. Turn on Sync settings so your preferences and some app data are saved to OneDrive. For photos and documents, open the OneDrive app and upload files manually, or set the tablet to automatically back up the Pictures and Documents folders.

If your Lenovo tablet has a Lenovo account (separate from Google or Microsoft), sign in to Lenovo's website and check whether cloud backup is available for your model. Some Lenovo tablets offer their own backup service.

What to do if the reset fails or gets stuck

If the reset process hangs or freezes, wait at least 30 minutes before assuming it is stuck—resets can be slow on older tablets or those with a lot of data. If the screen has not changed after 30 minutes, try a hard reset by holding down the power button for 10 to 15 seconds until the tablet shuts down completely. Wait 30 seconds, then press the power button again to turn it back on.

If the tablet will not turn on after a hard reset, it may have a drained battery. Plug it into a charger for at least 30 minutes, then try again. If it still will not start, contact Lenovo support—your tablet may need service.

If the reset starts but you see error messages, write down the exact error text and search Lenovo's support website for that error code. Different error codes point to different problems (storage issues, account problems, or software corruption), and Lenovo's support pages usually list the steps to fix each one.

After the reset: setting up your tablet again

Once the reset finishes and you see the setup screen, you will be asked to choose a language and connect to Wi-Fi. Sign in with your Google account (Android) or Microsoft account (Windows). This will restore apps you previously installed from the Play Store or Microsoft Store, as well as photos and documents stored in the cloud.

Reinstall any apps that did not restore automatically—open the Play Store or Microsoft Store and search for them. If you had app data (like saved games or settings within an app), that data may or may not be restored depending on whether the app developer backed it up to the cloud. Most major apps do, but smaller apps may not.

Frequently Asked Questions

Will a factory reset remove the password or PIN from my tablet?

Yes. The reset erases all security settings, so when setup finishes, the tablet will have no password or PIN. You can set a new one during the initial setup or later in Settings.

Can I stop a factory reset once it has started?

No. Once you confirm the reset, the process runs to completion. Interrupting it by turning off the tablet can leave it in an unusable state. Let it finish, even if it takes longer than expected.

What if I forgot my Google or Microsoft password and cannot sign back in after the reset?

Go to the sign-in screen and tap Forgot password? You will be guided through recovery steps using a backup email or phone number. Have access to the email address or phone number linked to your account before you start.

Does a factory reset remove the operating system?

No. The operating system (Android or Windows) stays on the tablet. Only your personal files, apps, and settings are removed. The tablet will still run the same version of Android or Windows it had before the reset.

How much storage space do I need free to do a factory reset?

You do not need extra free space. The reset process uses the space already on the tablet. However, if your tablet is almost completely full, the reset may fail—try deleting large files or apps before attempting the reset again.
