The reason is your computer forgets its CMOS settings. During the boot-up process or POST (Power-On Self Test) a checksum is generated by the BIOS from the CMOS and compared to the one saved the last time the CMOS Setup was run or the BIOS defaults were loaded. If the two numbers don't agree it is an indication that the data in the CMOS has been corrupted. and a checksum error is issued by the BIOS.

Reason:
A bad battery.
A battery that has become discharged (the computer has been off a very long time).
A disconnected battery.
Static electricity.
Grounding the CMOS circuitry.
A bad motherboard.
A bad real-time clock.


A simple solution you can try:
change the CMOS battery.

Write down all of the settings from the various setup menus.
Power off your PC.
Open the case and locate the battery on the motherboard.
Obtain a replacement battery from a local or online computer parts dealer.
Remove the old battery and replace it with the new one.
Replace the case and power on the PC.
Enter your PC's setup mode.
Reenter the settings you have written down from the various setup menus.

NAME
wmbattery - dockable battery monitor SYNOPSIS
wmbattery [options] DESCRIPTION
wmbattery is a battery monitor. It is used to visually display the system's battery status. wmbattery can get battery information using HAL, APM, ACPI, or the SPIC controller in some Sony laptops. You need to build your kernel with support for at least one of these for the program to work. wmbattery is dockable using WindowMaker and AfterStep window managers; under other window managers wmbattery appears as a nicely-sized 64x64 application. wmbattery displays the status of your laptop's battery in a small icon. This includes if it is plugged in, if the battery is charging, how many minutes of battery life remain, battery life remaining (with both a percentage and a graph), and battery status (high - green, low - yellow, or critical - red). ELEMENTS OF THE DISPLAY
The wmbattery display consists of these elements: dial The large dial at the top of the display shows battery life remaining. time display The time display, right under and in the middle of the dial, shows how many hours and minutes of battery life is estimated to remain at the current rate of use. If ACPI is used and battery is charging, the time display will instead show a countdown (starting with a minus sign) of how many hours and minutes it is estimated to take until the battery is fully charged. power cord The small icon of a power cord plug, in the bottom left, tells if the laptop is plugged into wall power. If so, it will be lit. charging indicator The lightning bolt icon, to the right of the plug, tells if the battery is being charged. If so it will be lit and will connect the plug to the battery. battery icon The battery icon, to the right of the lighting bolt, shows the percentage of battery time. If the battery is removed the icon will be dimmed. If the computer is low on power the battery will turn yellow; if the computer is critically low on power and about to die because of it, it will turn red. OPTIONS
-h Display list of command-line options. -w secs Pause this many seconds between updates. -d display Use the designated X display. -g +x+y Specify geometry. This specifies position, not size. -b battnum Display the given battery. Only of use with the HAL or ACPI interfaces on systems with more than one battery. The default is to dis- play the first battery found. -l percent Set the percentage at which the battery is considered to be running low. By default, this percentage is determined automaticall, and you shouldn't need to set it. If you set this, you should probably also set the -c switch. -c percent Set the percentage at which the battery is considered to be critically low. By default, this percentage is determined automati- cally, and you shouldn't need to set it. If you set this, you should probably also set the -l switch. -e wmbattery contains code for estimating the time remaining before discharge, and until full charge, and this code is used if no other source of this informaton is available. This switch makes wmbattery use its time estimation code even if some other estimate is available. -s granularity Ignore fluctuations less than the specified granularity percent when estimating time. (Implies -e) -a file.au Play the specified au file (by sending it to /dev/audio) when the battery is low. AUTHOR
