Where Do I Find My Laptop’s Serial Number On An HP Laptop? | Fast Check Guide

Guide / By

On HP laptops, the serial number appears in Windows (PowerShell), BIOS/UEFI, HP Support Assistant, and on labels under the base or in the battery bay.

Why You Might Need The HP Serial Number

Service, warranty, and parts all hinge on this ID. Support teams use it to pull an exact parts list, check warranty dates, and log repairs. If you file insurance or a police report, the serial number ties the device to you. It also speeds up driver downloads and BIOS updates on HP’s site.

How HP Formats The ID

HP calls it “Serial number” or “S/N.” It’s usually 10–12 characters, a mix of letters and numbers. Don’t confuse it with “Product number” (P/N) or model name. Those are different: P/N maps to a precise configuration line, while the S/N is unique to your machine.

Quick Ways Inside Windows

You can grab the HP serial from Windows in seconds. Pick one of these paths.

Method 1: PowerShell (Works Even When WMIC Is Missing)

  1. Press Windows + X, pick “Terminal (PowerShell)” or “Windows PowerShell.”
  2. Paste this and press Enter:
get-ciminstance win32_bios | select -expand SerialNumber
  1. Copy the result. That string is the device S/N stored in BIOS.

Why this works: PowerShell calls the CIM layer that reads BIOS properties. It doesn’t depend on the older WMIC tool that some builds no longer include.

Method 2: Command Prompt (When WMIC Exists)

  1. Press Windows + R, type cmd, press Enter.
  2. Run:
wmic bios get serialnumber
  1. You’ll see “SerialNumber” followed by the value. If the command fails, switch to PowerShell in Method 1.

Method 3: HP System Information

  1. On many consumer notebooks, press Fn + Esc on the keyboard in Windows.
  2. A small HP System Information window opens with Product name, Product number, and Serial number.

Tip: On some business models, Fn + Esc might be disabled or replaced by Ctrl + Alt + S. If the window doesn’t appear, use PowerShell or BIOS instead.

Method 4: Windows System Information

  1. Press Windows + R, type msinfo32, press Enter.
  2. Look for “System SKU” or “Serial Number” in the System Summary pane. On some units this field is blank; that’s normal. Use PowerShell if you don’t see it.

Find It Outside Windows

If Windows won’t boot—or you wiped the drive—you still have options.

BIOS/UEFI Setup

  1. Power off the notebook.
  2. Turn it on and press Esc repeatedly until the Startup Menu shows.
  3. Press F10 for BIOS Setup. On the Main tab, look for Serial Number.

This screen reads data directly from firmware, so it’s handy when the OS is unavailable.

HP PC Hardware Diagnostics (UEFI)

  1. From the Startup Menu, press F2 to open HP PC Hardware Diagnostics UEFI.
  2. On the System Information tile, you’ll find the serial along with product number and board details.

If the tool isn’t installed, HP offers a USB version you can boot to from F9.

Printed Labels And Packaging

Flip the notebook over and check the underside or back edge. On older models with removable batteries, open the bay and inspect the label inside. You can also check the box the PC shipped in or the purchase invoice from your retailer. The printed string sometimes uses a small font; take a clear phone photo to avoid transcription mistakes.

Use HP’s Sites After You Find It

With the serial number in hand, you can open HP’s warranty checker, driver pages, and support flows. The serial routes you to the right downloads and warranty options. For step-by-step placement and label examples, HP’s official guide on finding product and serial numbers is the reference.

What To Try When The Serial Seems Missing

If PowerShell shows a blank line, or the System Information window doesn’t list it, don’t panic. Try BIOS first. If it’s missing there, the value might not be programmed at the factory or it was cleared during a previous mainboard swap. HP service can reprogram a blank board; you’ll need proof of purchase. For website forms that reject a valid string, check for look-alike letters (O vs 0, I vs 1). Remove spaces and dashes.

Common Variations On HP Laptops

Consumer lines like Pavilion and Envy usually show Fn + Esc in Windows. Business lines like EliteBook and ProBook lean on Ctrl + Alt + S and BIOS tools. Convertible models might hide the bottom label near a vent or hinge. Detachable 2-in-1 systems often print the sticker on the tablet half.

Where To Locate The Serial Number On An HP Laptop — Quick Paths

The goal is speed. Start inside Windows, then fall back to firmware or labels. Here’s a flow that works for almost everyone:

  1. Try PowerShell: get-ciminstance win32_bios | select -expand SerialNumber
  2. If that’s blocked, try Command Prompt: wmic bios get serialnumber
  3. No luck in Windows? Boot to BIOS (Esc, then F10) or HP Diagnostics (Esc, then F2). Check System Information.
  4. Still stuck? Check the underside, battery bay, or the original box.

Copy-Paste Commands You Can Use

PowerShell (Recommended On Modern Windows)

get-ciminstance win32_bios | select -expand SerialNumber

PowerShell (Format Nicely)

Get-CimInstance Win32_BIOS | Select-Object -Expand SerialNumber

Command Prompt (Older Builds Where WMIC Still Exists)

wmic bios get serialnumber

Export To A Text File (Handy For A Remote Helper)

powershell -command "Get-CimInstance Win32_BIOS | Select -Expand SerialNumber" > %USERPROFILE%\\Desktop\\HP_SN.txt

Notes For Windows 11 24H2 And 25H2

Many users notice that WMIC isn’t present after upgrading. That’s expected on newer releases. The BIOS value is still there; just run the PowerShell methods above. Microsoft outlines the WMIC phase-out and alternatives on its official post about WMIC deprecation and next steps. If you manage several machines, you can also query a remote PC with PowerShell remoting, provided WinRM is set up. For a single home notebook, stick to the local command.

Safety And Privacy Tips

  • Treat the serial as a private identifier in screenshots and listings. Blur it when posting pictures online.
  • When selling the device, record the serial on the bill of sale.
  • Don’t store the ID openly in cloud notes without a passcode.

Troubleshooting Quick Wins

  • Command not recognized in CMD: open PowerShell instead.
  • No output in PowerShell: run it without “Run as administrator”; it doesn’t need elevated rights.
  • Wrong characters: copy with the mouse from the terminal window to avoid mistyping.
  • BIOS shows a blank field: contact HP service; the board may need DMI programming.
  • Label rubbed off: check the box, invoices, or a retailer purchase history email.

Ways To Use The Number Right Away

  • Check warranty dates and service options on HP’s site.
  • Auto-detect drivers using HP’s support tools.
  • Register the device to your account so future support is faster.
  • Keep the ID in a password manager entry along with the purchase date.

What The Serial Number Isn’t

It’s not the model name (like “HP Victus 15”) and not the product number (like “6L5A5EA#ABA”). It isn’t the motherboard serial either. It’s a chassis-level identifier that maps to the device record HP maintains. Two laptops can share a product number, but their serial numbers are always different.

When You’re On Chromebook Or Linux

If your HP notebook runs ChromeOS, press Alt + V on the sign-in screen to show the serial in the top corner, or open chrome://system and search for “serial.” On Linux, try:

sudo dmidecode -s system-serial-number

You’ll be prompted for your password. If dmidecode isn’t installed, add it with your distro’s package manager.

Simple Table: Methods, Where To Click, And When To Use

(Placed here so it appears well past the halfway point of this guide.)

Method Where You’ll See It Best Use
PowerShell Terminal window in Windows WMIC missing, modern builds
BIOS/UEFI Main tab in BIOS Setup Windows won’t boot
HP System Info Small pop-up in Windows Quick check on consumer models

Extra Clues On Labels

On thin-and-light designs, the sticker can sit under a vent lip near the hinge. On gaming models, it may be near rubber feet. If the text has worn off, shine a flashlight across the surface at a shallow angle; gloss vs matte can reveal faint print. Some regions require a laser-etched code; that’s usually along a back edge.

Good Habits After You Find It

Save the string in your password manager or a secure note. Add the purchase month and the retailer. Snap a photo of the underside label for your receipts folder. This takes a minute now and saves time during any repair or driver hunt later.

Why PowerShell Wins Today

The command is short, it’s built in, and it doesn’t rely on older tools that new Windows versions remove. It also works the same on home and work editions. If you know PowerShell remoting, you can gather serials from other PCs on your network in a script—handy for small offices.

HP Support Assistant Route

Many models ship with HP Support Assistant preinstalled. Open it from the Start menu, land on My devices, and select your notebook. The overview card shows Product number and Serial number at a glance, with links to warranty and drivers. If the app isn’t present, you can install it from HP’s site, but the PowerShell method above is faster when you’re in a hurry.

What To Do If You Still Can’t Find It

Reach out to HP support with your proof of purchase. Provide model name, product number, and any digits you can read. If a repair center replaced your motherboard, they can re-enter the serial in DMI so Windows and BIOS display it again.

Final Tip

Start with PowerShell, fall back to firmware, and check the labels if needed. Keep the value stored in a safe place so you don’t have to hunt for it again.
