Diagnostic 1 ,4 and battery lights are stable


That's TWO Problems bro: Your RAM is not SEATED properly and the CMOS Battery is probably very low. Pop the Side panel open with the computer UNPLUGGED. Check to see how many slots of RAM are in the PC. REmove them one at a time, then put them back in carefully, listening for a type of CLICKING sound that indicates proper seating of RAM STICKS. Remove the CMOS battery and install a NEW One. It looks like a NICKEL. After that, plug up the computer with the side panel STILL off to check and see if the lights stop blinking. If they do, shut the computer down again, UNPLUG it and re-fit the side access panel. PROBLEM SOLVED!!!

If this is an older PC (3-5 years or more) then most likely the backup battery on the motherboard has become weak.
On many motherboards this is a coin cell, which can easily be replaced (on others it is soldered in, though), just have a look.

I have Aspire T300 and now I power off the PC then turn off at the powerpoint - On start-up the next day the time clock has stopped and check settings and calender is stopped - any clues?


Yes, your little onboard battery that keeps the CMOS backed up has probably gone flat.  The PC needs to be opened up to replace this little flat shaped 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.
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
