When choosing a power supply for a laptop with 65W instead of 90W, it's important to ensure that the voltage and polarity of the new power supply match the requirements of the laptop. Additionally, the new power supply should have a compatible connector to the laptop's power input. It's also important to consider the charging time and performance of the laptop with the lower wattage power supply. It's recommended to consult the laptop's manufacturer or a certified technician to ensure compatibility and safety. **

When the Acer Aspire 5 is connected to the power supply, it only works in AC mode, meaning it is running on direct power from the electrical outlet rather than using its battery. This is a common feature in many laptops, as it allows the device to operate at its full performance potential without draining the battery. When the laptop is connected to the power supply, it is also able to charge the battery while in use, ensuring that it is ready for portable use when needed. **

For a notebook, a 65W power supply would be more suitable as it is designed to provide the appropriate amount of power needed for the device without overloading it. Using a 95W power supply may deliver more power than necessary, which could potentially damage the notebook's components over time. It is always recommended to use the power supply that is specifically recommended for the notebook to ensure optimal performance and longevity. **

An AC power adapter is designed to convert alternating current (AC) from a wall outlet to direct current (DC) to power a laptop. On the other hand, an AC/DC power adapter can convert both AC and DC power sources to the appropriate voltage needed for the laptop. AC/DC power adapters are more versatile as they can be used with different power sources, while AC power adapters are limited to converting AC power only. **

Acer laptops typically require a power supply that provides the correct voltage, current, and connector type to ensure compatibility. It is recommended to use an official Acer power supply or a third-party power supply that meets the same specifications as the original. It is important to check the laptop's user manual or the manufacturer's website to determine the specific power supply requirements for your Acer laptop. Using an incompatible power supply can potentially damage your laptop or cause it to not function properly. **

There could be several reasons for this issue. It could be due to a faulty AC adapter or power cord, a problem with the laptop's charging port, or a malfunctioning battery. It's also possible that there is a software or driver issue causing the laptop to switch between power sources. I would recommend trying a different AC adapter and power cord to see if the issue persists, and if it does, contacting Acer support for further assistance. **

An AC power supply is a type of electrical power supply that delivers alternating current, which periodically reverses direction. This type of power supply is commonly used in household electrical outlets and is the standard form of power transmission for most electrical grids. On the other hand, a DC power supply delivers direct current, which flows in only one direction. DC power supplies are commonly used in electronic devices such as computers, cell phones, and battery-operated devices. Both AC and DC power supplies are essential for providing the electrical energy needed to power various devices and systems. **

The Acer monitor typically requires a power supply of 100-240V, 50/60Hz. It is important to use the specific power supply that came with the monitor or a compatible one to ensure proper functionality and to avoid damaging the device. Always refer to the user manual or the specifications provided by Acer to determine the correct power supply for the monitor. **
