yes
Yes, you can use a PSP (PlayStation Portable) without a battery, but only if it is plugged into a power source using the AC adapter. The device will operate normally while it is connected to the power supply. However, if you unplug it, the PSP will turn off immediately without a battery present.
Yes, a cell phone can work while plugged in without the battery, provided it is designed to operate this way. Some devices are capable of drawing power directly from the charger. However, this is not universally true for all phones, as some may require a battery to complete the electrical circuit. Always refer to the manufacturer's guidelines for your specific device.
NO
No, as long as the power adapter is plugged in, the laptop will boot without the battery installed.
Computers don't have batteries so I'm assuming you're talking about a laptop. Laptops with their battery SHOULD work when its plugged in. Some laptops can even work WITHOUT the battery but still plugged in. However, if your battery has a critical flaw (dead short) then even with it plugged in, it won't work. I suggest you try the laptop with the battery removed. If it works, that is the problem, otherwise, your laptop has other problems.
You need a new battery. They do wear out. The laptop needs electricity to run, either with the electrical cord or with the battery. You cannot "trick" it into thinking it is plugged in any more than you can "trick" a car into running without gasoline or a T.V. into running without electricity.
To operate a Canon camera without a battery, you can use an AC power adapter that is compatible with your camera model. This adapter allows you to power the camera directly from a wall outlet, bypassing the need for a battery. Make sure to check the specifications of your camera and purchase the correct adapter to ensure compatibility.
Yes, a cell phone requires a battery to function, as it provides the necessary power for the device to operate. The battery supplies energy to the phone's components, including the screen, processor, and communication systems. Without a battery, a cell phone would not be able to turn on or perform any tasks. However, when connected to a power source, some phones may operate without a battery, but this is not typical for standard use.
Is your battery bad? If so, try booting up plugged in without the battery installed. Mine was freezing up shortly after login, but I have been running around half an hour without the battery, and so far it has not frozen up.
When I plug in my laptop, it does not use the battery to run the computer. Instead, it uses the wall outlet to run the computer and to recharge the battery. So, by leaving my battery in my laptop when it is plugged in, I am recharging my battery and not running it down. If you take the battery out of your laptop and do not recharge it, it will not last long. The computer batteries that I know about can go from 2 to 8 hours without being recharged.
You can run a PSP without it having a battery, it's not very convenient though. It will only operate while it has the charger in.
Removing the battery from a laptop can cause issues if the device is not plugged into a power source, as it may lead to data loss or corruption if the system shuts down unexpectedly. Additionally, some laptops may require the battery to function properly, especially if they rely on it for power management features. However, if the laptop is designed to work without a battery while connected to AC power, it should operate normally. Always ensure you save your work and shut down properly before removing the battery.
