The batteries of all notebook computers belong to consumables. At present, almost all brands of computers use lithium batteries, and the service life of lithium batteries is related to their charge and discharge times. Of course, this is also related to the use time of notebook computers. Under normal circumstances, after two or three years of use, the battery capacity of the new machine is about 70~80%, and it can still be used normally.
If the laptop battery is found to be faulty or suspected to be faulty, it is recommended to send the whole computer to the official after-sales service center of the corresponding brand, and the professional engineer will conduct a comprehensive inspection to confirm whether there is any fault, and then repair or replace it if necessary.
