How to Find the Part Number on Dell, HP, Lenovo and Fujitsu Parts
Share
The quickest way to buy the right spare is to search for the number printed on the part you are replacing. Model names are not enough, because one model of PC or server is often built with several versions of the same part.
Each manufacturer labels parts differently. Here is what to look for.
Dell: the DP/N
Dell parts carry a label marked DP/N, short for Dell Part Number. The part number is five characters, usually shown with a zero in front, such as 0X1234. On a longer barcode label it follows the two-letter country code: in CN-0X1234-12345-678-9ABC the part number is X1234.
Search for the five characters. You can leave off the leading zero. Browse our Dell spares.
HP and HP Compaq: the spare part number
HP uses numbers in the format 123456-001. A part may show two of them:
- The spare part number, often labelled Spare or SPS, is the number HP uses for replacements.
- The assembly number, sometimes labelled AS or Assy, is the factory number.
Either will identify the part. If one doesn't bring up a result, try the other. Server options are also sold under a third number that often ends in -B21. Browse our HP spares.
IBM and Lenovo: the FRU
IBM and Lenovo parts carry an FRU number, short for Field Replaceable Unit. It is seven characters, such as 46W0792 or 00AE912, and is printed next to the letters FRU. The label often shows a separate P/N as well. Search with the FRU first. Browse our IBM and Lenovo spares.
Fujitsu and Fujitsu Siemens: S26361 and A3C numbers
Fujitsu parts usually carry a number that starts with S26361, S26113 or A3C, followed by a longer code. Search for the whole number as printed, including the letters and dashes. Browse our Fujitsu Siemens spares.
Where the label is on common parts
| Part | Where to look |
|---|---|
| Motherboard | A white sticker on the board, often near the memory slots or the edge |
| Power supply | The large label on the side or top of the unit |
| Fan | The label on the hub in the centre of the fan |
| Hard drive | The main label, alongside the drive maker's own model number |
| Cable | A small flag label or a number printed on the connector |
| Memory | The sticker on the module |
| Laptop part | The underside of the part, so it usually has to be removed first |
If you can't read the number
Labels wear off and parts go missing. Send us the system's model and its service tag or serial number, with a photo of the part if you have one, and our engineering desk will identify it for you.
