HP 80XL302 manual Low Battery Signals and Actions, Operating and Handling, Maintaining

CAUTION:

1.If the “Low Battery Warning Beep” item is disabled in the SCU program, the notebook will not beep.

2.If the suspend-to-file partition does not exist or the “Suspend -to-File” item is not set in the SCU, the notebook will not be able to suspend to disk. It will keep on beeping until you take actions or until the battery runs out of charge.

3.If you are using a flash PC card, do not access the card upon low battery warning. The battery may run out of charge before the action is completed, thus making the access unsuccessful.

4.If you fail to save your data before the battery completely runs out of charge, then you lose your data.

Operating and Handling

•Never remove the battery pack while it is in use. If you need to replace the battery pack, make sure you have turned off the notebook power.

•Leave the battery pack in place unless you will replace it. If you remove the battery pack, keep it away from conductors such as metals and water. In case the battery’s pins get into touch with conductors, the battery may become unusable as a result of short-circuit.

•When you disconnect the AC adapter, disconnect from the electrical outlet first and then from the notebook.

•To prevent data loss that may be caused by low battery, develop the habit of frequently saving your data to the hard disk or a diskette.

•Do not attempt to disassemble the battery pack.

Maintaining

•When you install a new battery, fully charge and discharge the battery at least once and then fully charge the battery before you begin to use the battery power for the first time.

•Protect your notebook from extremes in temperature. (See “Environmental Specifications” in Appendix A for temperature range.)

Low Battery Signals and Actions

Low Battery occurs when the battery has approximately 10% of its charge remaining. The notebook gives warning beeps and the Battery Status Indicator ( ) blinks red to alert you to take actions.

Immediately save your data upon the Low Battery warning. The remaining operating time depends on how you are using the notebook: if you are using the audio subsystem, PC card, hard or floppy disk drives, the battery might run out of charge very quickly.

Always respond to the Low Battery warning by suspending your notebook to disk, turning off the notebook, or connecting the AC adapter.

If you do not take any action, after two minutes the notebook will automatically suspend to disk and turn off.
