A technician is configuring new laptops for an office deployment. Which TWO of the following statements correctly describe laptop power delivery standards and Lithium-ion (Li-ion) battery management best practices? (Select TWO.)
- USB-C Power Delivery (USB-PD) negotiates power levels between the host and device to allow high-wattage power transmission.Cevap
- BAll USB Type-C physical ports support high-wattage power delivery and Thunderbolt protocols regardless of host controller capabilities.
- Lithium-ion batteries do not suffer from memory effect, making full deep discharge cycles unnecessary and potentially harmful to long-term health.Cevap
- DLithium-ion batteries should be completely drained to zero percent on a weekly basis to calibrate memory and maintain capacity.
- EReplacing the screen display fluorescent inverter is required when a laptop battery fails to charge from the AC adapter.
Cevap
The correct statements are that USB-C Power Delivery negotiates power levels between the host and device to allow high-wattage power transmission, and that Lithium-ion batteries do not suffer from memory effect, making full deep discharge cycles unnecessary.
USB-C Power Delivery allows dynamic negotiation of higher wattage profiles suited for charging laptops, while Lithium-ion batteries perform best without deep discharge cycles because they do not suffer from battery memory effect.
