What does the battery in your desktop computer run?
It powers the BIOS memory, keeping your bios settings active, and it powers the clock.
Where is battery situated on a desktop computer?
The only battery in a desktop computer is the one used to keep the clock running when the machine is powered down, provide some juice for the BIOS to start, and keep a few neurons of CMOS memory alive so that the machine knows what to do when the power-on button is pressed. It's nothing but a small silver 'button', like a wrist-watch battery, typically on the motherboard.
Does bios empty its contents when the computer is turned off?
Only if the BIOS battery is flat or out of circuit.
Why does time keep changing on desktop PC?
You might have to replace the BIOS battery.
Is BIOS a volatile or nonvolatile memory?
BIOS is a program (stored in ROM), not a memory.However the BIOS uses a battery backed up RAM to store a variety of settings and parameters. This BIOS RAM is itself volatile (it can only store data when powered), however the battery backup provides power to this RAM when the main power of the computer is off (making it act as if it were nonvolatile). When this battery dies the BIOS RAM will lose its data and (after the battery is replaced) the machine may have to be reconfigured from scratch before the machine will startup correctly.
What memory is readable but not writeable in a chip computer?
BIOS chip
How does BIOs maintain its memory when the computer is off?
The BIOS itself is stored in ROM which does not require any power to maintain its contents. The BIOS setting are stored in a very low power CMOS SRAM with a battery to keep it powered up even when the computer itself is switched off (the BIOS does nothing to maintain this, it is done in the hardware).
BIOS and cm-os settings are maintained by what?
a battery in the computer
What tells your computer to display your desktop start programs display the time and show you where your files are kept?
The computer's BIOS.
What should be done if BIOS settings are set to default whenever you boot your system?
The reason that causes your BIOS to reset to its defaults is a dead battery. Because CMOS (BIOS settings) is a volatile form of memory, the memory chip needs a constant power source, even when the computer is off. To supply this, there is a coin battery located directly on the motherboard. Simply replace this with the exact same kind and you shouldn't have any more problems.
What is c mos battery?
It's the battery on a Motherboard/Similar COmputer Component that allows it to retain BIOS information
Is laptop a classification of computers?
Yes...a laptop is a computer. Basically the same thing as a desktop computer, only smaller. It has a motherboard, processor, memory, BIOS...etc. The same parts as a "normal" computer, only smaller!! That's primarily why the cost more. The engineering behind it.
