Elitegroup 557 - Manual (Page 40)

Battery Low Warning
When the pack initially reaches the “Battery Low” state approximately 10 ~ 15 minutes of the
usable battery life is left. You will hear an audible beep signal every 1.5 seconds alerting you to
the “Battery Low” status. When the battery power reaches the “Battery Low Low” status the
beeping sound will accelerate. Your battery now has 1 ~ 2 minutes of battery charge remaining.
You must save your data or connect AC power immediately; otherwise, you may lose your data.

Small Battery for the Real Time Clock
There is a small built-in battery pack that supplies power to the system in order to maintain
certain system information while the power is off.
If the Notebook is left without a power source for long period of time, this battery will be
exhausted and system information will be lost.
Danger of explosion if battery is incorrectly replaced. Replace only with the same or
equivalent type recommended by the manufacturer. Dispose of used batteries according to
the manufacturer's instructions. Never remove the battery pack while the power is on as this
may result in data loss when the system loses power.
Resetting the System
After installing a software application package, you may be prompted to reset the system to load
the changed operating environment. To reset the system, or “reboot,” press the [Ctrl] + [Alt] +
[Delete] keys simultaneously. This is known as “warm boot.” This key combination acts as
“software” reset switch when you encounter hardware or software problems, which lock up the
Notebook.
If this key combination does not shut down the Notebook, you can reset the Notebook by using
the Notebook’s power button. Should the Notebook lock up for some reason, pressing this button
powers the Notebook off.
