Laptop

What is the primary trade-off with laptop compactness for troubleshooting and component replacement?

The compact design makes troubleshooting and replacing internal components more challenging due to precise specifications and delicate parts.

What are the two main types of laptop batteries, and why are they preferred over older technologies?

Lithium-ion and lithium-ion polymer. They are preferred as they do not suffer from the "memory effect," allowing them to be recharged at any time without capacity loss.

How does laptop battery modularity vary, and what are the replacement implications?

Some are highly modular and user-replaceable via a simple button. Others are built-in, requiring a technician's disassembly, increasing replacement difficulty.

What is the most commonly replaced laptop component and why is it often easy to replace?

The keyboard. It's often easy because manufacturers design them for removal by unfastening a few screws or a bezel, and they connect via a simple ribbon cable.
