Getting CMOS checksum error
SOURCE: CMOS battery replacement
Your Pc should have an Intel E210882 motherboard in it.
A coin-cell battery (CR2032) powers the real-time clock and CMOS memory. When the computer
is not plugged into a wall socket, the battery has an estimated life of three years. When the
computer is plugged in, the standby current from the power supply extends the life of the battery.
The clock is accurate to ± 13 minutes/year at 25 ºC with 3.3 VSB applied.
When the voltage drops below a certain level, the BIOS Setup program settings stored in CMOS
RAM (for example, the date and time) might not be accurate. Replace the battery with an
equivalent one. Figure 14 shows the location of the battery.
These batteries are very common and can be purchased at Wal-Mart, Walgreens, Etc...
Here is a link to the motherboard manual with battery replacement procedures:
