Laptop and PC Accessories

Universal accessory or model-specific part: the first question

This aisle holds two kinds of product. Universal accessories work with any computer that has the right port or size: cables, adapters, hubs, glasses and carrying cases sold by screen size. Model-specific parts must match one laptop exactly: chargers, batteries, screens, fans and keyboards. Ports decide the first group, and the model number decides the second. If your goal is more connections for one laptop, start with USB-C and laptop docking stations; if you are repairing or powering one, see laptop parts and add-ons.

Power, ports and protection: the checks for each family

For power, read the wattage and plug type; a USB-C charger must support Power Delivery at your laptop's wattage. For connections, check which USB-C ports can carry video, since most docks and adapters need that to drive a monitor. Cables and adapters should state the standard, for example HDMI 2.1 or USB 3.2, not only the plug shape. For protection, size a case by the laptop's screen diagonal and leave room for the charger. Blue light glasses are a comfort accessory and do not affect the computer.

Questions about Laptop and PC Accessories

How do I know a laptop part fits my model?

Match the exact model or part number printed on the old part or the service label, not just the brand and screen size. Batteries, screens and chargers are model-specific, and similar names can hide different connectors.

Can one USB-C charger power any laptop?

Only if it delivers enough wattage and supports USB Power Delivery. A laptop that needs 65 W will charge slowly or not at all from a 30 W charger. Check the wattage on the laptop's original adapter.

Does a laptop case size just follow the screen size?

Screen diagonal is the starting point, but body size also depends on bezels and thickness. Look for the case's maximum laptop size and inside dimensions, and leave room for the charger if you plan to carry it.
