Update to the latest BIOS version
CMOS clock battery indicator shows that the CMOS battery is dead Connect
the AC adapter
for at least 24 hours, and then run BIOS Setup to reconfigure the system
System CMOS has been corrupted or modified incorrectly, perhaps by an
application that changes CMOS data In response, the BIOS has installed the
default Setup values Use BIOS Setup to modify these values if needed If the
error persists, check the system battery Connect the AC adapter for at least
24 hours; replace the motherboard
Timer test failed Replace the motherboard
Real-time clock failed the BIOS test Might require replacing the motherboard
BIOS found the date or time to be out of range, and then reset the real-time
clock You might need to use BIOS Setup to reset the legal date
Previous POST did not complete successfully POST loads default values and
offers to run BIOS Setup If the failure was caused by incorrect values that are
not corrected, the next boot will likely fail This error is cleared the next time
the system is booted
Memory size found by POST differed from that specified in CMOS
Drive A: is present but fails the BIOS POST diskette tests Make sure the drive
is defined with the proper diskette type in BIOS Setup, and that the drive is
connected correctly
Type of floppy drive A: not correctly identified in BIOS Setup
