Hi,

The small, on system board, battery that maintains the flash (CMOS) settings is probably kaput and needs replacing .

You probably need to replace the on-board battery.

Dell Inspiron 530. At start up gives CMOS checksum error defaults loaded. Options press F1, F2 or F12 computer does not react. Has new CMOS battery. RAM OK. Did CMOS clear and password reset. What else can...


When a Power Supply is plugged into power, there is a constant 5 Volts present. The 5 Volt Standby Power.

You press the Power On button.
This in turn presses against the Power On switch, located inside it's plastic assembly.

The Power On switch is a Momentary Contact Switch.
Temporary closing it activates the Soft Power On circuit.
A 5 Volt circuit that utilizes the 5 Volt Standby Power.

The Soft Power On circuit 'excites' the Power Supply, and turns it on.
(Sounds like a seedy novel)

The first chipset (Integrated Circuit) to receive power is the BIOS chipset.
The Basic Input/Output System program is initialized.

BIOS looks to see what devices are connected, does a Ram Memory count, turns the Processor on, and hands the computer over to the Operating System.

A checksum is computed as an error-detecting code, to protect the BIOS settings stored in CMOS.
Each time the computer is turned on, this number is re-computed; and checked against stored values.

If they do not match an error message is generated, to tell you the CMOS memory contents may have been corrupted; and therefore some settings may be wrong.
Your BIOS assumed the settings were incorrect, and loaded BIOS default settings; stored in BIOS.

(Default = factory settings)

CMOS Checksum Error Defaults - Loaded

New battery? Nope didn't help.
Clear CMOS, and password reset? Nope didn't help.

Leaves Virus as the problem, or hardware component/s on motherboard; are bad.

My thoughts?
Bad motherboard.

("BAD motherboard. NO,...........you know you have been bad,....don't give me that look. You're a bad motherboard."

Lol!)

That's my diagnosis.


(Unless you put the CMOS battery in upside down.
+ goes UP)

My motherboard will boot but CMOS will not hold the settings


Hi,
This problem is usually caused by a dead or damaged CMOS battery which is a flat, chrome battery about 2 thirds of an inch in diameter and located on the motherboard.
The battery powers the memory which stores your CMOS settings and devices installed such as hard drives.
Replacing this battery should solve your problem.

Best wishes,
Graeme

You need to go into your BIOS and turn this function off....If you can't access your BIOS, you'll
need to clear your CMOS which will reset your BIOS back to factory defaults

Bios is missing


When you power up the computer press F1 or F2 or "del" key.
Also try TAB or F5 or F8 or F12 Then if you not able to see bios setup then you need to reset bios to factory defaults.
For that you need to open cpu cabinet then pull cmos cell from motherboard for 10 minutes also change cmos cell if it has low voltage.
You can RESET bios with jumper settings to.
For that find on motherboard jumper named "Clear cmos"
It has 3 pins .1-2-3 put jumper in 2-3 position then power up then put jumper again into it's original position.Then all settings are defaults.
If then still bios is not come then you need to update the bios.
You can download bios from motherboard company web sites then copy it into usb flash drive or disk then boot your computer with it then you can update bios.Motherboard web sites provides you command how to upgrade bios.
Let me know if you need further assistance.
Thanks for using FixYa.

Pull cmos cell from motherbord for 10 minutes so all settings are goes to defaults.
Also you can reset its settings with jumper settings.
You can see 1 jumper onmmotherbord near cmos cell.
Read carefully on bord you read there RESET or CLEAR bios.
it has 3 pins.set jumper in 2-3 position then power up .
Then again set to its original position 1-2.
Then all settings defaults.
Let me know if you need more assistanse.
