When a laptop stops working, the part you fit into it decides how long the repair lasts. A genuine spare part restores original performance, while a duplicate part often fails within weeks and can damage other components. The problem is that both look almost the same on a shop counter.
Here is a simple, practical guide our engineers use every day to verify the authenticity of laptop spare parts before they go into a customer machine.
1. Check the part number and label
Every genuine component carries a manufacturer part number, model code and often a barcode or QR code. Match this number with the number printed on the part you are replacing. Blurred printing, spelling errors, missing certification marks or a label that peels off easily are clear warning signs.
2. Inspect build quality and finish
Genuine parts have clean moulding, uniform colour, precise connector alignment and no rough edges. Duplicate batteries and adapters usually feel lighter than expected because they use less copper and smaller cells.
3. Verify compatibility, not just appearance
- Screens: check size, resolution, connector pin count and backlight type
- Batteries: check voltage, watt-hour rating and connector shape
- Adapters: check output voltage, amperage and barrel size
- Keyboards: check layout, ribbon width and mounting points
4. Ask for a bill and warranty
A genuine seller will always give a proper invoice and a written warranty period. If a shop refuses a bill or offers a price far below the market rate, treat it as a red flag. The cheapest part is rarely the cheapest repair.
5. Buy from a trusted service partner
The safest route is to buy through an authorised service partner who tests each part before fitting it. At AIS – Aghanya Info Solution, every spare part is sourced through verified channels, bench tested and installed by trained engineers with warranty support.
