CMOS Error Message

Data stored in the hard disk becomes inaccessible after you encounter a CMOS (Complementary metal-oxide-semiconductor) error message. In such situations, in case of absence of an up-to-date backup, you need to use powerful data recovery software. Few main CMOS error messages that you might encounter are:

Error Message: CMOS/GPNV Checksum Bad. CMOS Date/Time Not Set?.

Reasons:

CMOS values are incorrect

BIOS is not updated

Improper system shutdown

CMOS battery not functioning properly

Error Message: CMOS battery low

Reasons:

CMOS battery not functioning properly

System off for several hours/days

Error Message: CMOS memory size wrong

Reasons:

Improper setting of CMOS jumper

CMOS values are incorrect

Software bug in BIOS

Error Message: CMOS display type mismatch

Reasons:

Failure of video card

Incorrect BIOS settings

Failure related to motherboard

Error Message: CMOS system options not set

Reasons:

Hardware is modified and the System BIOS options are forced to change

Values stored in CMOS RAM are either corrupt or nonexistent.

Few measures after CMOS error:

Reinitialize the BIOS

Change the BIOS battery

Remove all software bugs

Change the old CMOS battery with a brand new one

However, if all the above measures fail to resolve the CMOS error and your data remains inaccessible, then use Stellar Phoenix Windows Data Recovery software. This is an advanced and easy to use data recovery application that recovers data after all the above CMOS error messages. Compatible with Windows 7 RC1, Vista, XP, 2003 and 2000, this non-destructive data recovery application supports 185 file types. Built with highly graphical user-interface, the software recovers data from deleted, damaged, or formatted FAT, FAT16, FAT32, NTFS and NTFS5 hard drive partitions.
