The following table lists POST messages and explanations for reported problems. If the system fails after you make changes in BIOS Setup, reset the notebook, enter BIOS Setup, and install the defaults or correct the error.

Table 3-2. POST Messages

MessageDescription

0250 System battery is dead – Replace and run SETUP

The CMOS clock battery indicator shows the battery is dead. Connect the AC adapter for at least 24 hours. Replace the motherboard.

0251 System CMOS checksum bad – Default configuration used

System CMOS has been corrupted or modified incorrectly, perhaps by an application program that changes data stored in CMOS. The BIOS installed Default Setup Values. If you do not want these values, enter BIOS Setup and enter your own values. If the error persists, check the system battery. Connect the AC adapter for at least 24 hours; replace the motherboard.
