You can't charge the wireless keyboard directly.
1, the USB interface of the computer usually only provides current for external devices to use, and can not achieve the charging function of the wireless keyboard.
2, wireless keyboard usually need to use battery power, if the battery is low, you need to replace the battery or connect the keyboard to a special charging device to charge.
3, Some wireless keyboards may provide rechargeable batteries, but they usually provide additional charging devices or charging docks for recharging.
Wireless keyboards usually use Bluetooth or other wireless technology to connect to the computer, due to limited battery life, need to be replaced or recharged regularly to ensure normal use.
At the same time, in order to facilitate users, some wireless keyboards are designed with rechargeable batteries and related charging equipment, and users can choose the appropriate wireless keyboard according to their needs.
No. The computer's wireless keyboard will not charge after it is turned off. Wireless keyboards require a power supply and Bluetooth connection to work properly, which will be cut off when the computer is shut down.
If you want to continue using your wireless keyboard after your computer is turned off, consider using a wired keyboard or setting your computer to sleep mode. In sleep mode, the computer's system goes to sleep, but the Bluetooth connection and wireless Internet connection remain on, so the wireless keyboard can continue to charge.
Not because the line is disconnected, the computer is shut down, the power cord is disconnected and cannot be powered on, so only in the standby state, can you charge the board keyboard
can not be charged
If your computer is turned off, it is equivalent to being disconnected from the power supply, then plugging in the wireless keyboard will not be able to charge 1. Because the power supply is disconnected after the computer is shut down, the wireless keyboard cannot be connected to the power supply for charging.
You can't charge it after you turn it off.
Charging method: Connect the wireless keyboard, charging cable and charging head and plug it into the socket to make the display light on the keyboard red, indicating that it is in a charging state, and the red light will turn green after the charge is full, indicating that you are fully charged, which is we timely unplug the keyboard and data cable, and connect the keyboard and computer through Bluetooth mode to normally use the wireless keyboard
When your computer is shut down, it is equivalent to disconnecting the power supply, and of course, the wireless keyboard can not be charged at this time, but if your unlimited keyboard is a USB interface, you can charge it through the charger of your phone, which is more efficient.
It can't be recharged.
The 5V voltage of the computer USB interface is controlled by the motherboard, not directly connected to the power supply, when the computer is not turned on the motherboard naturally will not output voltage, it will not be able to charge peripheral devices. The mouse cannot be charged at this time.
Computer shutdown can still charge the wireless keyboard, because some keyboards support keyboard boot, which must be powered off when the keyboard, you can try to set the BIOS, in the BIOS to turn off the keyboard mouse boot function.

This is because once the laptop is turned off, then his power supply is also in the power output of the shutdown, that is to say, it is stopped, even if you are connected to the phone for charging, he can not charge, just like you use the mobile charging power to charge the phone, if the power supply is turned off, it can not charge the phone
Agreed. Laptop lithium battery life is limited, beyond the battery life, it can not be charged. Therefore, in order to maintain the \"maximum life\" of the battery, it is necessary to try to run out of electricity and then charge, generally do not start charging after the battery runs out of sleep, and the power is about 8%.
This is not able to charge the wireless keyboard, all because there is no current after the computer is shut down, but also to make this can not produce voltage, so that it can not be charged small.
Agreed. As soon as you plug it in, the computer instantly switches to mains power mode. When charging, the power supply needs to supply power to the notebook and battery at the same time, the load is larger, and the heat generated by the power supply is large. When charging, only the battery is powered, the load is small, and the heat is small. Therefore, when the notebook is running at high speed and the interior is overheating, it is better to shut down and charge, otherwise it is harmful to the battery
As long as the keyboard is rechargeable, after plugging in the computer, as long as the USB port on the computer has charging current output, it can be charged.
It is recommended that you try it after shutting down. If you cannot charge the external device, you are advised to enable the \"always on USB\" in the BIOS to enable the shutdown charging function.
