IdeaPad. IdeaPad (stylized as IDEAPΛD and formerly ideapad) is a line of consumer-oriented laptop computers designed, developed and marketed by Lenovo. The IdeaPad mainly competes against computers such as Acer 's Aspire, Dell 's Inspiron and XPS, HP 's Pavilion, Envy, Stream, and Spectre, Samsung 's Sens and Toshiba 's Satellite.
Battery charger. Charging a 12 V lead–acid car battery. A mobile phone plugged in to an AC adapter for charging. A battery charger, recharger, or simply charger, [1][2] is a device that stores energy in an electric battery by running current through it. The charging protocol—how much voltage, current, for how long and what to do when ...
The ThinkPlus charger is a power adapter designed for Lenovo ThinkPad laptops, providing the necessary power to charge the battery and operate the device. Its key features include compatibility with specific ThinkPad models, varying power output (typically measured in watts), and the ability to operate with different input voltages.
The ThinkPad Yoga series laptops have a "backlit" keyboard that flattens when flipped into tablet mode. This is accomplished with a platform surrounding the keys which rises until level with the keyboard buttons, a locking mechanism that prevents key presses, and feet that pop out to prevent the keyboard from directly resting on flat surfaces.
Electronic components have a wide range of failure modes. These can be classified in various ways, such as by time or cause. Failures can be caused by excess temperature, excess current or voltage, ionizing radiation, mechanical shock, stress or impact, and many other causes. In semiconductor devices, problems in the device package may cause ...
Memory effect. Memory effect, also known as battery effect, lazy battery effect, or battery memory, is an effect observed in nickel-cadmium rechargeable batteries that causes them to hold less charge. [1][2] It describes the situation in which nickel-cadmium batteries gradually lose their maximum energy capacity if they are repeatedly recharged ...
An electrical injury, (electric injury) or electrical shock (electric shock) is damage sustained to the skin or internal organs on direct contact with an electric current. [2][3] The injury depends on the density of the current, tissue resistance and duration of contact. [4] Very small currents may be imperceptible or only produce a light ...
The cut-off voltage is different from one battery to the other and it is highly dependent on the type of battery and the kind of service in which the battery is used. When testing the capacity of a NiMH or NiCd battery a cut-off voltage of 1.0 V per cell is normally used, whereas 0.9 V is normally used as the cut-off voltage of an alkaline cell ...
