How Do I Know Which Laptop Part Fits My Model?

Match the part number printed on your old part first, then the exact model name from the label under the laptop. The series name alone is not enough, because two laptops in one series can use different parts. For screens also match size, resolution and pin count. For chargers match voltage, tip size and wattage.

Price ranges in this answer are market estimates. Live NN Laptops prices are below.

Part numbers are the surest check, because the same part number means the same part, whichever laptop it came from. The model name comes second. The series name, such as ProBook or Inspiron, tells you very little on its own.

NN Laptops listings name the model a part is sold for. We do not publish a full list of other models each part fits, so if your model is not named, send us the part number or a photo and we check it before you pay.

Key factors

Find the exact model

Read the label under the laptop. On Windows you can type wmic csproduct get name in Command Prompt. On a MacBook, the A-number is printed on the bottom cover.

Read the old part

Batteries, fans, keyboards and screens usually carry a label with a part number or code. Take a clear photo before you order, because the laptop maker may have used more than one version.

Screens

Match size, resolution, pin count (30 or 40), connector position, and refresh rate on gaming models. A touch panel only replaces a touch panel.

Batteries

Match the pack code on the battery label and its voltage. A different code can mean a different shape or connector, even on the same model.

Chargers

Match the voltage and the tip size or USB-C type exactly. The wattage should be the same as the old charger or higher.

Keyboards

Match the layout, the Enter key shape, the number pad, the backlight, and whether a frame is attached.

RAM and SSDs

Check the memory type, such as DDR4 or DDR5, and whether RAM is soldered. For an SSD, check the slot type (M.2 NVMe, M.2 SATA or 2.5-inch) and the length, such as 2280.

Top picks by tier

You can read the part number

Pick: Search that number or send it to us on WhatsApp 0314 4000131

This is the surest check and it takes a minute.

You only know the model

Pick: Use the Laptop Part Finder, then confirm the fit on WhatsApp

The finder shows what is listed for that model. The WhatsApp check covers versions of the model that use a different part.

You are not sure which part is faulty

Pick: Bring the laptop to the Hafeez Center repair desk in Lahore

Diagnosis comes first, so you do not pay for a part that will not fix the fault.

Most common mistake

The most common mistake is matching by looks or by series name. Connectors differ by one pin and batteries differ by a few millimetres, and neither shows in a photo of the whole part. Match the printed numbers.

Can a part from a different model fit my laptop?
