How to Check Laptop Warranty (HP, Dell, Lenovo, Apple, Asus, Acer)
To check laptop warranty, find the serial number (or the service tag on a Dell) and enter it on the brand's own warranty page. HP, Dell, Lenovo, Apple, Asus and Acer all have free lookups that show the warranty start and end dates and often the country the laptop was sold in. This guide shows where to find the number, which site to use for each brand, and what international warranty really means for buyers in Pakistan.

Find your serial number or service tag
Every warranty lookup needs the laptop's serial number. Take it from the laptop, not only from the box.
- Bottom label: most laptops print the serial number (S/N) on a sticker or laser-etched on the base.
- Windows: open PowerShell and run Get-CimInstance Win32_BIOS | Select-Object SerialNumber. On older systems, wmic bios get serialnumber in Command Prompt works too.
- BIOS setup: the main or system information page shows the serial number.
- Mac: Apple menu > About This Mac.
Some brands use their own names. Dell calls it the service tag, a 7-character code. Lenovo shows the serial number next to the machine type (MT or MTM), a 4-character code at the start of the product number. Acer also prints an SNID, a numeric code that its support site accepts. If the label, BIOS and box numbers differ, ask why before you pay.
HP warranty check by serial number
Go to support.hp.com and open the warranty check page. Enter the serial number; HP sometimes asks for the product number as well, which is on the same label (it looks like a short code ending in a region suffix, for example #ABA or #ABU).
The result shows the warranty start date, end date, the type of coverage and usually the country or region it applies to. On many HP laptops you can also press Fn + Esc to open a System Information window with the serial and product number, or use the HP Support Assistant app if it is installed.
HP business models such as EliteBook, ProBook and ZBook often show longer or business-level coverage than consumer Pavilion or Victus models. If the lookup shows a different model name from the laptop you are holding, the label or motherboard may have been changed.
Dell service tag warranty check
Go to dell.com/support and type the service tag into the search box, or let Dell detect it with the SupportAssist app. The page shows warranty status, ship date, the country the system was shipped to and, very usefully, the original configuration: CPU, RAM, storage and display.
Compare that configuration with the laptop. If Dell lists an i5 with 8GB RAM and the laptop now has 16GB, the RAM was upgraded later. That is fine if the seller tells you; it is a problem if a lower CPU or screen was swapped in.
Dell also prints an Express Service Code, which is a numeric version of the same service tag. Either one works on the support site. Latitude, Precision and XPS models often had longer warranties when new than Inspiron or Vostro, so the end date tells you a little about how the laptop was first sold.
Lenovo warranty check
Go to pcsupport.lenovo.com and open Warranty Lookup. Enter the serial number; for some models Lenovo also asks for the machine type. Lenovo Vantage (on consumer laptops) and Lenovo Commercial Vantage (on ThinkPads) show the same details from inside Windows.
The result lists the base warranty, any upgrades bought with the laptop, the start and end dates and the ship-to location. ThinkPads are often sold with on-site or extended business warranties, so a used ThinkPad may still show active coverage in its original country.
The lookup also confirms the exact model. A ThinkPad T14 Gen 3 and Gen 4 look almost the same from outside, but they carry different processor generations, so the warranty page is a quick way to confirm you are getting the generation you paid for.
Apple warranty check
Go to checkcoverage.apple.com and enter the serial number. The page shows:
- Whether the purchase date is validated.
- Telephone technical support status.
- Repairs and service coverage: active, expired, or covered by AppleCare.
If Apple has no proof of purchase, it may estimate the start date, and the page will ask you to validate it. A buyer can update this later by giving Apple a valid receipt. For MacBooks, also check Activation Lock, Find My and MDM before buying; a Mac with a valid warranty can still be locked to someone else's Apple ID. Our MacBook iCloud and cycle count guide covers those checks step by step.
Asus and Acer warranty check
Asus: go to the Asus support site and open Warranty Status Inquiry. Enter the serial number from the bottom label or from the MyASUS app. The result shows the warranty end date and region. ROG, TUF, Zenbook and Vivobook all use the same lookup.
Acer: go to the Acer support site, enter the serial number or SNID, and open the warranty section for that product. The Acer Care Center app shows both numbers on many models. Acer Nitro, Predator, Swift and Aspire laptops all use the same page.
For both brands, check that the model name in the lookup matches the laptop exactly. Gaming laptops in particular come in many close variants (for example, different GPUs under one series name), and the lookup is the easiest way to confirm the variant.
International warranty in Pakistan, brand by brand
Most laptop warranties are tied to the country or region where the laptop was first sold. Some product lines carry wider coverage, but the terms differ by model and change over time, so treat this as a starting point and confirm with the brand's support before relying on it.
- HP: some commercial models carry worldwide or travel coverage; consumer models are usually limited to the region of sale.
- Dell: warranty service is generally delivered in the country of purchase; Dell offers transfer and international options mainly for business customers.
- Lenovo: many ThinkPad models are covered by Lenovo's International Warranty Service; consumer IdeaPad and Legion models vary.
- Apple: Mac hardware warranty is generally honoured where Apple or its authorised service providers offer service, but there is no Apple Store in Pakistan and authorised service options are limited.
- Asus and Acer: some models carry international or traveller warranty, often premium or gaming lines; many budget models do not.
Local service partners may ask for a local invoice. An imported laptop with active coverage abroad is not automatically serviceable here.
Reading the result: red flags
- The model name in the lookup does not match the laptop.
- The warranty started years ago on a laptop sold as new.
- The lookup shows no record at all for the serial number.
- The serial in the BIOS is blank or reads like a placeholder (for example, To Be Filled By O.E.M.), which usually means a replaced motherboard.
- The seller promises a year of warranty but cannot say whose warranty it is or put it in writing.
Any of these is a reason to ask questions or walk away.
Shop checking warranty vs brand warranty
A brand warranty is a promise from HP, Dell, Lenovo, Apple, Asus or Acer, delivered through their service network. A shop warranty is a promise from the seller only.
Our stock is Non Custom box pack imported as international variants, so we do not offer a brand warranty on it. Every order instead comes with a 7-day checking warranty from delivery. Use that week to run the serial lookup, check the battery and storage, and test every port and key. If anything is not as described, contact us within the seven days. Our warranty and returns page has the full terms. Orders need an advance (currently 15%) and the balance is paid to the courier on delivery; there is no cash on delivery.
