Resetting the NVRAM is a quick, easy, way to troubleshoot a misbehaving Mac—it doesn`t delete any data from your storage drive, and it doesn`t require any tools or repair experience.
Computer manufacturers mainly use NVRAM to hold information about the state of the computer for faster boot times. This allows information about the components and devices in the computer to be stored from one use to the next while the system power is turned off.
To remove all data from your phone, you can reset your phone to factory settings. Factory resets are also called “formatting” or “hard resets.”
A Scanner Error 22 error message displays on the printer control panel when you try to scan from the printer. This error might display when extra weight or pressure is applied to the scanner glass, such as when scanning an open book. The weight or pressure can stall the scanner mechanism.

WARNING: Clearing the CMOS or NVRAM using a jumper resets the passwords in the BIOS. This includes the BIOS user password, admin password, and hard drive password. This does not include any other passwords such as Windows login, online accounts, and so on.

Settings that can be stored in NVRAM include sound volume, display resolution, startup disk selection, time zone, and recent kernel panic information. The settings stored in NVRAM depend on your Mac and the devices that you`re using with your Mac.
Perform a power reset (or hard reset) to clear information from the computer`s memory without erasing personal data. Note: If you are trying to reset Windows 11 or Windows 10, see HP PCs – Reset the computer.
Turn the printer on, and immediately put your fingers on the return (u-turn) button, home button, and one in the lower right corner of the screen (next to the question mark button). Wait until the screen said Permanent Storage Init. You`re good after that, it will reset. Thank you…
