Cmos checksum bad boots to the splash screen then goes black with a blinking white line tried reseting the jumper cmos no luck load default settings no luck removed psu and battery no luck


This error is not the same as a CMOS Checksum Error, which refers to corrupted values of the CMOS settings, the ones you set through the BIOS setup program. This error means the contents of the BIOS code itself are damaged.


During the boot process you will see on the screen a certain key to press to enter setup
Press and hold that key during the boot up process to enter BIOS you can load failsafe defaults or load optimized defaults ,press escape then press f10 to save to cmos to restart
You will also need to set the time and date

In the main or system setup screen you should be able to see the date and time Using your arrow keys navigate to the date and change the date. Once highlighted on the month, day, or year, press your arrow keys or your page up / page down keys to change the date.

hope this helps you

My Laptop is Dellstudio15,When I swith on my laptop is showing error while booting it self is: Check date and time settings,System CMOS Checksum is Bad.Please help on this.


This error message means that its time for you to replace you CMOS battery.

CMOS battery is a small battery on the system board that provides power to the Complementary Metal Oxide Semiconductor (CMOS) chip, even while the computer is turned off. This chip contains information about the system configuration (e.g., hard disk type, floppy drive types, date and time, and the order in which the computer will look for bootable disks). The CMOS battery allows the CMOS to preserve these settings.


Hope this information willbe helpful. Thank you for using FIXYA.

I get the message "Bad check sum (CMOS)" Model toshiba tecra 730XCDT


hi friend,

Probably a dead Motherboard battery. Need to enter the BIOS screens and reset values. Especially the time and date. Maybe the boot order and if using USB KBoard enable legusy USB devices. This will occur each time your friend shuts down and reboots until the battery is changed.
Issue
When you turn your Toshiba computer on, you see an error message like: **** Bad RTC battery ****
**** Bad Checksum (CMOS) ****
Check system, then press [F1] key The Real Time Clock (RTC) battery provides power for the internal clock/calendar and for maintaining system configuration settings.
This error can occur when a machine has been left turned-off for an extended period of time (around a month), and is the result of a depleted RTC battery. Other symptoms include not being able to execute Windows Update properly, errors/problems executing application software (like Norton Antivirus), and the appearance of the Windows XP "Desktop Clean Wizard".
Resolution This condition is easy to fix in 3 basic steps: Reset the BIOS defaults
Set the correct date and time in Windows.
Charge the RTC battery Please follow the detailed instructions in the next section.
Procedure Set BIOS defaults Press the [F1] key as instructed in the error message:
**** Bad RTC battery ****
**** Bad Checksum (CMOS) ****
Check system, then press [F1] key In the BIOS setup screen press the [Home] key to restore the default values, then press the [End] key to save and exit, then the [Y] key to confirm and restart the system. Set the correct date and time in Windows As Windows starts-up, you may see an error message about an "Invalid System Time". Go ahead and click "OK" to clear the error dialog. Open the Windows Control Panel and open the "Date and Time" control by double-clicking its icon. Set the correct date and time, then click OK to save. Charge the Real Time Clock (RTC) battery To charge the RTC battery, connect the AC adapter and turn the computer on (both the DC IN and Power LEDs must be green). Leave the machine on for approximately 24 hours to ensure a full charge in the RTC battery. Please note that the RTC battery does not charge while the PC is turned off, regardless of whether the AC adapter is connected or not. Other Information: If, on subsequent reboots, the "Bad RTC Battery" error persists, it's quite likely that you actually do have a bad RTC battery. If that's the case, you should contact a Toshiba Authorized Service Provider to have the system serviced. Windows XP Desktop Cleanup Wizard The first time you reboot Windows XP after resetting the system clock, Windows XP may try to run the "Desktop Cleanup Wizard". Simply Cancel the "Desktop Cleanup Wizard" at the first dialog. If you do manage to clean your shortcuts from the desktop and want to recover them, you will find them in a folder called "Unused Desktop Shortcuts". You can recover them as follows: Double-click to open the "Unused Desktop Shortcuts" folder
Click to expand the "Edit" menu, and click "Select All"
Drag the selected items back to your desktop
Close the "Unused Desktop Shortcuts" folder. You can delete this folder if it is empty.

Turn on computer and message reads ****bad check sum (CMOS) ****


That means that after computer had been off for a long time the CMOS battery has drained, and CMOS (BIOS) settings had been reset to default.

Usually the computer will work fine after pressing F1, but you may get wrong date and time.

Try charging battery completely, often the problem disappears, if it does not , then the choice is between pressing F1 each time you start the laptop, or disassembling the laptop and replacing CMOS internal coin battery, located on the lower side of the motherboard.

Boots to 'CMOSS checksum error'


CMOS checksum errors
Explanation: A checksum is computed as an error-detecting code, to protect the BIOSsettings stored in the CMOS memory.Each time the system is booted this number is recomputed and checked against the storedvalue. If they do not match, an error message is generated to tell you that the CMOSmemory contents may have been corrupted and therefore some settings may be wrong. BIOSesreact in different ways to encountering this sort of error. Some will warn the user andthen continue on with whatever settings were in the CMOS. Others will assume that thesettings that were in the CMOS were corrupted and will load default values stored in theBIOS chip "for safety reasons". The error message will indicate which yoursystem is doing.
Diagnosis: The most common cause of checksum errors in CMOS is a battery that islosing power. Viruses can also affect CMOS settings, and motherboard problems can alsoaffect the stored values.
You should make sure that all of theBIOS settings in the system are correct, by rebooting the system, going into BIOS setupand double-checking all the values (hopefully against a recent BIOS settings backup).
If you have created a backupcopy of your CMOS settings then use them to restore the settings to the correctvalues. To find the problem itself:

Asus motherboard bios version1104


Whether it shows your cmos checksum error press F1 to continue or f2 to load default.? If this is the problem than kindly switch off the system check for the cmos battery and change the cmos battery and set the date and time properly in the bios and save it by pressing F10.This will resolve your problem.and if not than check the jumper setting on the motherboard is it set to clear cmos and if so kindly remove and set it properly to adjacent jumper ok. Have a nice time.
