No. The work of CMOS battery is to keep date and time up to date. It won't prevent the computer from booting, you will loose date and time. Computer will boot as per it's default BIOS settings or you will have to manually choose the drive where the OS is installed.

The BIOS is a small program that controls the computer from the time it powers on until the time the operating system takes over. The BIOS is firmware, and thus cannot store variable data. CMOS is a type of memory technology, but most people use the term to refer to the chip that stores variable data for startup.

An error occured while updating the device software. ... Use the Emergency recovery function in the Smart Switch PC software' The screen stays on for about 30 seconds and then the phone shuts down. I can only do this while the phone is connected to a charger. If it's not connected to a charger, it won't boot up.

PMOS LDOs also tend to have a lower dropout voltage than most PNP LDOs. The lower dropout voltage allows the PMOS LDOs to operate from a lower input voltage, which also extends the useful life of the battery.

Unfortunately, not all CMOS batteries are removable. Some manufacturers only allow a replacement battery to be added. If your computer does not have a coin cell battery, refer to your documentation or contact your computer manufacturer for further assistance.

The BIOS setup has also been called the "CMOS setup" or "CMOS RAM," because settings were initially held in a battery-backed CMOS memory circuit. Subsequently, BIOS settings were stored in non-volatile flash memory. this is the type of battery that will power the CMOS when the PC is not plugged in.

Google services aren't the only culprits; third-party apps can also get stuck and drain the battery. If your phone keeps killing the battery too fast even after a reboot, check the battery information in Settings. If an app is using the battery too much, Android settings will show it clearly as the offender.

It can take a few hours, or sometimes all you need to do is shut down and restart. A full shutdown with Instant-On turned off so it has to go through the full reboot process.

Without Ram, your computer will not boot. It will beep at you a lot. It may briefly turn on the cpu fan and gpu fan to beep at you but that's heavily dependant on 1000s of factors. A dead cmos battery won't stop a computer.
