Internal clock i have Toshiba Tecra M2 which is about 5 years old. Every time it is powered up it has " forgotten" the correct time and date etc. I suppose it is because there is an internal battery that is defunct. How do I fix it ?

Re: internal clock

That is correct. There is a battery inside that needs replace. You need to take the bottom cover off and find the battery inside and replace it.
It should be a CR2032

Here's what it should look like:

Every time I power on my laptop, the date and time is set to years ago. I've changed it to the correct date and time a lot, turn it off when I'm done, but it goes back once I turn it back on. I have a...

You need to change the internal clock battery. It's referred as a CMOS battery or a system battery. It will most likely be a silver button cell...either a 2016 or 2032. You will most likely find it by removing the main battery and one of the bottom access covers. After you change it, boot up to Windows and change the time and date. It should now retain the settings.

Time and date are not set correctly

When the Date and Time is set in the BIOS setup or in Windows and when you boot up next time and the date and time are incorrect then the problem is a flat BIOS battery. A flat BIOS battery cannot keep the Data and Time stored in the BIOS. Replace the BIOS battery and set the Date and Time etc and the problem will be fixed.

What year was the toshiba tectra A3 made

Hello qtnick, the closest date that is recorded is 2001, this seem to be when the "Tecra Series" was being put into production, I've researched many references, but there wasn't a pinpoint date on any specify model. There is mostly the focusing on the "Newer Models ie: Tecra 9 the predecessor of previous models, and the "Newest" release Tecra 11. So most models were put in to production after 2001. Thanks for your question, paul7of 9

The RTC (Real Time Clock) battery charges when the computer in on (operating). You can plug the electrical cord in and let the computer run for 24 hours by temporarily suspending any sleep mode or automatic power saving features. This should sufficiently charge the RTC battery.

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.
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.
