In that case replace the Cmos battery, usually underneath the keyboard, and enter the BIOS to reset the clock. Select default settings in the menu.
Hope that helps.

Every time i boot up my brand new dell vostro i get an error: 00c08270 real time clock error - check time and date settings. I have been continuously updating the time and date but the error message keeps...


Meaning the RTC battery needs to be replaced.

The Real Time Clock battery is the CMOS battery.

http://support.dell.com/support/edocs/systems/vosA860/en/sm/index.htm

Coin-Cell Battery

The laptop has to be completely disassembled down to the motherboard (System Board) in your hand.
On the bottom of the motherboard is the RTC Battery.

Since the laptop is brand new this falls on the place where you purchased it, or Dell.
It is still under warranty as far as replacing the RTC Battery. (It came with a bad battery. They need to replace it, not you)

When I turn on my latop shows two error messages 0250; System battery is dead, 0270, real time error. and does not raise the operating system.


Hello and welcome to FixYa.Com
The 0250 error indicates your CMOS battery is dead and needs to be replaced. This is a common issue on machines once they get a few years old.
The 0270 error indicates your main board is not getting the date and time from your BIOS. This is more than likely directly related to the 0250 error.
You have 2 choices: 1. Replace the battery yourself. - Not so easy but not very expensive. 2. Take it to a professional repair location and have them do it. - Easy but expensive.
If you go option 1 then he following website contains very detailed instructions on replacing the CMOS battery in a R31. http://www.edmartechguide.com/2010/03/ibm-thinkpad-r31-laptop-disassembly.html
If you go option 2 then the cost should run you anywhere from $25 - $100 depending on their labor rate. Always get an estimate first and make sure they understand exactly what you want done.
I hope this helps, and dont forget to vote!

Buenas tardes, tengo un portatil ibm trinkpad typo 2656 y me genera este mnesaje a la hora del inicio y el sistema no arranca, por favor su colaboracion para solicionar este inconveniente. muchas gracias...


hola,
El mensaje que te muestra el portátil es debido a que la batería CMOS está defectuosa/cortocircuitada. Esta batería no tiene nada que ver con la batería externa del portátil, es una pequeña pila que alimenta una memoria dentro del ordenador. Esa memoria almacena la configuración de la BIOS-http://es.wikipedia.org/wiki/BIOS. Lo que te dice el ordenador es que tienes que reemplazarla.
Es una batería de tipo botón, en ésta página web explican como cambiar la batería CMOS, aunque está en inglés tiene fotos muy buenas:
http://www.edmartechguide.com/2010/03/ibm-thinkpad-r31-laptop-disassembly.html
El modelo de la batería CMOS es CR2032. Podrás conseguirla en cualquier tienda de electrónica o en ebay. Sustitúyela y problema resuelto.

compaq is HP so best is to ask them, there, now here.
RTC error mean , the RTC coin cell is dead.
all PCs this old are dead battery ,
RTC= real time clock chip says IM DEAD, but is battery dead ,..

remove the coin cell, and put in a new one.
end story.

best is to set time in BIOS setup. 1st.

this Compaq is 18 years old now. or 126 dog years.
id , push it off a cliff on the 4th July with fireworks. and all.
let me guess its XP the VIRUS magnet.
some this old are windows 98
a hopeless case there, no? no support, no books and no updates.
the books at HP are long gone
so now all books are , sold by horders. $$$
it can be costly and dangerous to deal with folks like that.

seen here
see coin, remove it and put in new one. end story.

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.

thank u for using fixya

regards,

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.

Boot error accures


THE BEST SOLUTION IS TO FORMAT IT AND REINSTALL THE OPERATING SYSTEM. IF YOU DON'T KNOW HOW TO DO SO, BETTER CONTACT YOUR SYSTEM VENDOR OR IT PROFESSIONAL.

Booting problem


I suspect your machine is an IBM Thinkpad 770.

The Error 0270 means you must replace the lithium coin cell battery. Google "Thinkpad (your model) support" and read the manuals for instructions.

With a new battery installed, boot into Setup by pressing the F! key. Reset the clock and verify that the hard drive is recognised.

Reboot, all might be OK. If not, download and run IBM's free PC-Doctor utility to test the machine. If all is OK, I suspect the hard drive was stripped and an operating system must be installed. Verify this with a DOS boot floppy. Run FDISK to view your partitions.

Good luck.
