Problem: The floppy disk drive cannot read or write a diskette.

The diskette is not yet formatted, or could be corrupted.

If you can’t write to a diskette, the diskette may be write-protected. Check to ensure that the write-protect tab covers the detection hole.

If you can’t write to a diskette, the diskette may be full. Use another diskette.

Problem: The message “non-system disk” or “disk error” appears on the screen after you turn on the system.

You may have inserted a non-bootable diskette in the floppy disk drive. Remove the diskette.

Check the SCU program to ensure that the drive types are correctly identified.

If this message is issued when you attempt to boot from your hard disk drive, insert a bootable diskette and check the integrity of your hard disk drive.

Problem: The date and/or time is incorrect.

Correct the date and time using the SCU program or your operating system.

If the date and time are still incorrect, it can be that the RTC battery is discharged after the notebook has not been used for a very long time. If so, connect the AC adapter to charge the RTC battery for 8 hours and then keep the notebook power off for one hour. Then run the SCU program to reconfigure the system.

Problem: The battery cannot be fully recharged.

For safety reasons, several factors can stop the recharging, e.g., when the battery's temperature gets above 40° C (104° F) or the recharging time exceeds 4 hours. To avoid problems caused by the temperature factor, make sure the battery does not get too hot. To avoid problems caused by the time factor, you are advised to keep the notebook power off during recharging. If you use the notebook during recharging for more than 4 hours, the recharging will stop no matter whether the battery has been fully recharged or not. If this happens, you can disconnect and then reconnect the AC adapter to start the recharging again.

Problem: The battery cannot be recharged.

Recharging will not start if the battery's temperature is below 0° C (32° F) or above 40° C (104° F). Make sure the battery's temperature is within the range.

Problem: No sound is produced.

Confirm the audio driver is installed.

Check if software-dependent volume control is set too low.

Problem: Distorted sound is produced.

Ensure the volume control is not set too high or too low. In most cases, high settings can cause the audio electronics to distort the sound.
