This error is typical of a problem with the system board.
I've only seen this error appear on IBM thinkpads. Your EEPROM with the following steps.
You can try this to test the EEPROM
1.unplug AC,battery, HDD and and your cd/dvd rom drive.
2.press power button,last more than 10 seconds
3.plug battery and AC power
5.when see the IBM logo,press F1 button immediately.
If the same error pops up, try it a few more times. If the error keeps displaying then it is the motherboard
