Before you buy a laptop in Bangladesh, and before warranty runs out, it is worth checking the warranty on the manufacturer’s own website. This guide shows where to find your serial number and links to each brand’s official warranty-check page.
Step 1: find the serial number
- On the laptop: look for the sticker on the underside (labelled S/N, Serial No. or, on Dell, Service Tag).
- On the box and invoice: the serial number is printed on the box label and should be on your purchase invoice.
- In Windows: open PowerShell and run
Get-CimInstance Win32_BIOS | Select-Object SerialNumber. - On a Mac: Apple menu > About This Mac shows the serial number.
Step 2: check on the brand’s official page
| Brand | Official warranty check |
|---|---|
| HP | HP warranty check |
| Lenovo | Lenovo warranty lookup |
| ASUS | ASUS warranty status inquiry |
| Dell | Dell support (enter the Service Tag) |
| Acer | Acer: how to check warranty status |
| MSI | MSI: how to check warranty status, plus MSI’s official product serial validation for Bangladesh |
| Apple | Apple Check Coverage |
MSI’s Bangladesh page is especially useful before you buy: according to MSI, it confirms whether a laptop was officially imported through MSI’s authorised partners in Bangladesh.
Step 3: read the result carefully
- Start and end dates: brands usually count warranty from the purchase or shipping date. If you have no valid invoice, MSI, for example, says it calculates warranty from the manufacturing date.
- Region: global checkers may show the country the laptop was first sold in. Warranty service in Bangladesh is handled through the brand’s local partners, so keep the seller’s invoice.
- Nothing found? Check the serial for easily confused characters (0 and O, 1 and l), then ask the seller.

- Laptop warranties range from 1 to 3 years depending on brand and model; batteries and adapters are covered for 1 year.
- Only the warranty period written on the Byte City invoice applies. Keep it safe.
