What Resetting Your Lenovo Computer Means

Resetting a Lenovo computer wipes the hard drive and reinstalls Windows (or whatever operating system came with it), returning the machine to the state it left the factory. This removes all your files, programs, and settings. The process takes 30 minutes to two hours depending on your internet speed and which reset method you choose.

You have two main paths: Reset This PC, which is built into Windows and works on most Lenovo laptops and desktops, or a Lenovo recovery partition, which some models have instead. Both accomplish the same end result, but the steps differ slightly.

Reset your Lenovo when it runs slowly due to malware or clutter, when you plan to sell or give it away, or when Windows stops working properly. Do not reset if you have files you need — back them up to an external drive or cloud storage first.

Key Takeaways

  • Back up all your files to an external drive or cloud service before you start, because resetting deletes everything on the computer.
  • Most Lenovo computers use Windows' built-in Reset This PC tool, found in Settings under System, and you can choose to keep or remove your files.
  • Plug your Lenovo into power before you begin, because the reset will fail if the battery dies partway through.
  • The reset process takes 30 minutes to two hours and requires an internet connection to read Windows files.
  • After the reset completes, you will need to sign in with a Microsoft account and reinstall any programs you want to use.

How to Reset Using Windows Settings (Most Lenovo Models)

This method works on Lenovo ThinkPad, IdeaPad, Yoga, and Legion models running Windows 10 or Windows 11. Plug your computer into power first — this is critical, because the reset will stop if your battery runs out.

Open the Start menu and type Settings. Click the Settings app. On the left side, click System, then scroll down and click Recovery. Under "Reset this PC," click the blue Reset PC button.

Windows will ask whether you want to Keep my files or Remove everything. Choose "Keep my files" if you want to preserve your documents, photos, and music but remove programs and settings. Choose "Remove everything" for a complete factory reset. Most people choose "Keep my files" unless they are selling the computer or dealing with malware.

Next, Windows asks how you want to reinstall: Cloud read or Local reinstall. Cloud read downloads a fresh copy of Windows from Microsoft's servers — this is slower but gives you the newest version. Local reinstall uses files already on your computer — this is faster but may not include the latest updates. Choose cloud read if your internet is reliable and you have time; choose local reinstall if your internet is slow or unreliable.

Review the summary screen, then click Reset. Windows will restart your computer and begin the reset process. Do not turn off your computer or unplug it. The screen will go black, show a spinning circle, and eventually restart several times. This is normal. The whole process takes 45 minutes to two hours depending on which option you chose.

How to Reset Using Lenovo Recovery Partition (Older Models)

Some older Lenovo computers have a recovery partition — a hidden section of the hard drive that holds a backup copy of Windows. If your Lenovo does not have the Recovery option in Settings, it may have this instead.

Restart your computer. As soon as it starts up, before the Lenovo logo appears, press Ctrl + Home repeatedly. (On some older models, press Novo Button — a small button on the side or bottom of the laptop.) A menu will appear with options including "System Recovery" or "Restore."

Click System Recovery or Restore. Follow the on-screen prompts. You will be asked to confirm that you want to erase the drive and restore to factory settings. Click yes. The recovery will take 20 to 45 minutes. Do not interrupt it.

If you cannot find the recovery partition or the Ctrl + Home method does not work, your Lenovo likely uses the Windows Settings method instead. Go back to the previous section.

What Happens After the Reset Completes

When the reset finishes, your Lenovo will restart and show the Windows setup screen. You will be asked to choose your language, region, and keyboard layout. Then you will sign in with a Microsoft account — either an existing one or a new one you create on the spot.

Windows will read and install updates, which can take 15 to 30 minutes. Your screen may go black or show a spinning circle. This is normal. Do not turn off the computer.

Once setup is complete, you will see a blank desktop. Your programs are gone — you will need to reinstall anything you want to use. If you chose "Keep my files," your documents, photos, and downloads will be in their usual folders. If you chose "Remove everything," those are gone too.

Reinstalling Programs After Reset

After your Lenovo finishes resetting, you will need to reinstall the programs you use. Common programs like Microsoft Office, Chrome, Zoom, and Spotify are not included — you read them fresh from their websites or from the Microsoft Store.

For Lenovo-specific software like Lenovo Vantage (which manages drivers and settings), visit support.lenovo.com, enter your model number, and read the drivers and software for your computer. Install Lenovo Vantage first, because it will help you install other Lenovo tools.

For Microsoft Office, visit office.com and sign in with your Microsoft account. If you own Office, you can read it from there. For other programs, go to their official websites — never read from third-party sites, because those often bundle unwanted software.

Common Problems During Reset

The reset stops or fails partway through. This usually means your battery died or your internet connection dropped. Plug in power, wait 10 minutes, then try again from the beginning. If it fails a second time, restart your computer and try the Lenovo recovery partition method instead.

You forgot to back up your files. Once the reset is complete, your files are gone and cannot be recovered by normal means. If the reset is still in progress, unplug the computer when ready to stop it — you may be able to recover some files with data recovery software, though this is not may provide. If the reset is already done, your files are permanently deleted.

Your computer is stuck on the setup screen. Make sure you have an active internet connection. If you do, restart the computer and try again. If it still gets stuck, try the reset again but choose "Local reinstall" instead of "Cloud read."

You cannot find the Recovery option in Settings. Your Lenovo may be too old for the Windows Settings method. Try the Lenovo recovery partition method using Ctrl + Home. If that does not work, your computer may need a Windows installation disc or USB drive, which you can create on another computer using Microsoft's Media Creation Tool.

When to Reset vs. When to Troubleshoot Instead

Resetting is a last resort, not a first step. If your Lenovo is running slowly, try these first: restart the computer, uninstall programs you do not use, run Windows Defender (built-in antivirus), and delete temporary files using Disk Cleanup.

If your computer has malware or a virus, run a full scan with Windows Defender or Malwarebytes before you reset. Sometimes malware can be removed without resetting. If the scan finds nothing but the computer is still slow, then reset.

If Windows will not start at all, you may need to reset. But first, try restarting in Safe Mode by holding Shift while clicking Restart, then choosing Troubleshoot. If Safe Mode works, your problem may be a bad program or driver, not a broken Windows installation.

Frequently Asked Questions

Will resetting remove viruses and malware?

Yes. Resetting wipes the entire hard drive and reinstalls Windows, so any malware is deleted. However, if you have malware on an external drive or cloud storage, it could reinfect your computer after the reset. Scan any external drives with antivirus software before you plug them back in.

Can I reset my Lenovo if I forgot my password?

Yes. On the Windows login screen, click "Reset your password" and follow the prompts to reset it using your Microsoft account email. If you do not remember your Microsoft account password either, you can reset that on the Microsoft website. If you cannot access either, you can still reset your Lenovo using the recovery partition method, which does not require a password.

How long does a reset actually take?

The reset itself takes 30 to 90 minutes depending on your internet speed and which method you choose. After that, Windows setup takes another 15 to 30 minutes. Plan for two hours total. Do not interrupt the process or unplug your computer.

Do I need a Windows installation disc or USB drive?

No, not for most Lenovo computers. The built-in Reset This PC tool and the recovery partition both work without a disc or USB drive. You only need a disc or USB if your hard drive is damaged and neither method works, which is rare.

What if I want to keep my files but remove a specific program?

You do not need to reset. Go to Settings, click Apps, find the program, and click Uninstall. Resetting is overkill for removing a single program. Reset only if you want to wipe everything and start fresh.
