Enter your Lenovo serial number in the Warranty Lookup box on Lenovo's website to see whether your laptop or desktop is still covered and when the coverage ends.
This guide shows where to find the serial number, how to run the lookup online or from Lenovo Vantage, how to read the results, and what to do when the dates are wrong.
The fastest way to check your Lenovo warranty
Lenovo's lookup takes a laptop or desktop serial number and returns the warranty status, with options to extend or renew from the same page.
- Open the Lenovo PC Services page in any browser.
- Find the Warranty Lookup box.
- Type your serial number into the field under Or, Manually Enter:.
- Click Submit.
- Read the warranty status and end date on the results page.
If you are on the Lenovo PC itself, Detect my Serial Number fills the number in for you, but it needs the Lenovo System Bridge helper installed.
Which way to check should you use?
| Your situation | Use this | Why |
|---|---|---|
| You have the serial number or can read the sticker | Warranty Lookup, manual entry | Works from any device, nothing to install |
| You are on the Lenovo PC and do not know the serial | Warranty Lookup, Detect my Serial Number | Reads the number from the PC once Lenovo System Bridge is installed |
| Lenovo Vantage is already installed | Lenovo Vantage | Shows device details without opening a browser |
| The PC will not boot | Serial from the label, then Warranty Lookup on another device | The lookup does not need the PC to be working |
What You Need Before Checking Your Lenovo Warranty
| Item | Why you need it | Where to get it |
|---|---|---|
| Serial number | The lookup is keyed to it; each device has a unique one | Label on the device, BIOS, or PowerShell (next section) |
| Proof of purchase | Needed if the warranty start date is wrong or the lookup shows nothing | Your receipt or order confirmation |
| Lenovo account | Needed to register the device and buy Premium Care | Create one on lenovo.com |
| Access to the PC or its box | To read the serial if you have not written it down | The device, its packaging or your order email |
How to Find Your Lenovo Serial Number
Lenovo prints the serial number on a sticker, usually on the bottom of a laptop, and stores it in the system BIOS. Windows can read it back from the BIOS with one command.
- Turn the laptop over and look for the label on the bottom panel; on a desktop, check the back or side of the case.
- If the label is worn off, right-click Start and select Terminal or Windows PowerShell.
- Type
(Get-CimInstance Win32_BIOS).SerialNumberand press Enter. - Copy the string that appears on the next line; that is the serial number.
- If Windows will not start, open the BIOS setup screen and read the serial from its main information page.
The original box and your order confirmation often carry the serial number as well, which helps when the device is lost or stolen.
How to Check Warranty Status on Lenovo’s Support Website
Use this route when you are on a phone, a different computer, or a PC that does not boot.
- Go to the Lenovo PC Services page and scroll to Warranty Lookup.
- To read the serial from this PC, click Detect my Serial Number and allow Lenovo System Bridge to install if prompted.
- Otherwise, type the serial number under Or, Manually Enter:.
- Click Submit.
- Note the warranty type and the expiry date shown for your product.
- Use the extend or renew option on the same results page if coverage is ending.
How to Check Warranty Coverage Using Lenovo Vantage
Lenovo Vantage is Lenovo's own app for device settings, updates and support. It is free from the Microsoft Store and comes preinstalled on many Lenovo PCs.
- Select Start and type
Vantageto find the installed app. - If it is not installed, open Microsoft Store, search for Lenovo Vantage, and select Get.
- Open Lenovo Vantage and let it identify your device.
- Open the device or support area of the app and look for the warranty entry.
- Compare the end date with the website lookup if anything looks wrong.
If Lenovo Vantage does not show warranty information, use the website lookup instead; it reads the same Lenovo records and needs nothing installed. Legion gaming PCs use the separate Lenovo Vantage for Gaming app.
How to check the lookup found the right device
- Compare the product name on the results page with the model on your device label.
- Confirm the serial number on the results page matches the one you typed, character by character.
- Check that the warranty start date is close to your purchase date on the receipt.
If all three match, the expiry date shown is the date Lenovo will use for repair claims.
Understanding Your Lenovo Warranty Details
The results page lists one line per coverage plan on the device. These are the terms you are most likely to see.
| What you see | What it means |
|---|---|
| Status (active or expired) | Whether the device is covered today |
| Start and end dates | The coverage window; the start is normally near the purchase date |
| Base or standard warranty | The coverage that shipped with the device |
| Premium Care | A paid upgrade with 24/7 phone, chat and email support, on-site support and prioritized repair |
| Premium Care Depot | The depot-repair version, offered for Chromebooks and tablets |
| Accidental Damage Protection (ADP) | A paid plan that covers accidental damage, which the standard warranty does not |
What to Do If Your Warranty Information Is Missing or Incorrect
The lookup returns no result
A mistyped serial number is the usual cause; letters like O and I are easy to confuse with 0 and 1.
- Read the serial again from PowerShell with
(Get-CimInstance Win32_BIOS).SerialNumber. - Paste it into the lookup instead of typing it.
- Try Detect my Serial Number on the PC itself.
The warranty shows expired on a device you just bought
The start date may be tied to an earlier ship date, or a new purchase may not have reached Lenovo's records yet.
- Register the device to your Lenovo account.
- Wait a few days and run the lookup again.
- If the dates are still wrong, contact Lenovo Support with your receipt or order confirmation and ask for a warranty correction.
The wrong product or a different warranty appears
The serial belongs to another unit, often after a motherboard replacement or a second-hand purchase.
- Compare the model name in the results with the device label.
- Gather the label photo, the PowerShell output and your proof of purchase.
- Send them to Lenovo Support so it can update the record.
Options for Extending or Renewing Lenovo Warranty Coverage
The Warranty Lookup results page offers extend and renew options for eligible devices. For Yoga and IdeaPad consumer PCs, the main upgrade is Premium Care.
| Option | What it adds | Timing rule |
|---|---|---|
| Premium Care | 24/7 support, on-site support, prioritized repair (Yoga, IdeaPad) | Add within 90 days of device purchase |
| Premium Care Depot | Premium support with depot repair (Chromebooks, tablets) | Add within 90 days of device purchase |
| Premium Care Plus | Lenovo's widest consumer coverage, including accidental damage | Check eligibility on the lookup results |
| Accidental Damage Protection (ADP) and ADP One | Repairs for drops, spills and other accidents | Check eligibility on the lookup results |
| Service bought before the warranty ends | Starts the day after the standard warranty expires | No gap in coverage |
| Service bought after the warranty ends | Starts on the purchase date | Only for devices in good working order |
Lenovo only sells these services for products in good working order, so buy before a fault appears. If you also own a Dell, the Dell warranty status check works the same way with a Service Tag.
Frequently Asked Questions
How do I check my Lenovo laptop warranty?
Enter the laptop's serial number in the Warranty Lookup box on Lenovo's PC Services page and click Submit. The results show whether the laptop is covered and when the warranty ends. On the laptop itself, Detect my Serial Number can fill the number in for you.
Where do I check my Lenovo warranty status online?
Use the Warranty Lookup on Lenovo's website, found on the PC Services page at lenovo.com. It accepts a laptop or desktop serial number and shows the warranty status, with options to extend or renew. It works from any browser, so the PC does not need to be on.
How do I find the serial number on my Lenovo laptop or desktop?
Check the label on the bottom of the laptop or on the desktop case. In Windows, run (Get-CimInstance Win32_BIOS).SerialNumber in PowerShell to read it from the BIOS. The original box and order confirmation usually list it too.
Can I check Lenovo warranty status by serial number only?
Yes. The serial number is all the Warranty Lookup needs. You do not have to sign in or install anything to see the warranty status, although registering the device to a Lenovo account is required to buy Premium Care.
Can I check Lenovo warranty status without installing Lenovo Vantage?
Yes. Lenovo's online Warranty Lookup needs only the serial number and runs in any browser. Lenovo Vantage is optional; it is useful if it is already on the PC, but the website shows the same warranty status.

Register the device to your Lenovo account and check again after a few days. If the dates are still wrong, contact Lenovo Support with your receipt or order confirmation and ask for the warranty start date to be corrected.
Can I extend my Lenovo warranty after it has expired?
Sometimes. Lenovo says service bought after the standard warranty expires starts on the purchase date, and only for devices in good working order. Premium Care itself must be added within 90 days of device purchase, so check the options on your lookup results.
What is the difference between standard Lenovo support and Premium Care?
Standard support is available by phone, chat and email during business hours. Premium Care adds 24/7 support, on-site support, a preventative PC health check and prioritized repair. Lenovo offers Premium Care on Yoga and IdeaPad devices and Premium Care Depot on Chromebooks and tablets.
Bottom Line
Run Lenovo's online Warranty Lookup with the serial number from your device label or PowerShell. It needs no software, works even when the PC is dead, and shows the extend or renew options for that exact device. If you want Premium Care, decide within 90 days of purchase.
