If the Time Remaining for the battery is not correct
•
The Time Remaining is an estimate based on the rate at which the computer is using
power at the moment, and so assumes that you will continue using power at that rate
until the battery runs out. So, if you check the Time Remaining while the computer is
using a good deal of power (such as when reading from a CD or DVD), the value will
likely show less time remaining than you really have, since you will probably later
switch to tasks that require less power.
If the computer doesn’t suspend to Standby mode as expected
•
If you have a connection to another computer, the computer won’t suspend if the
connection is active.
•
If the computer is performing an operation, it normally waits for the operation to
finish before suspending.
If the computer doesn’t automatically hibernate as expected
•
For Windows 2000 or XP, make sure hibernate support is enabled: from Control
Panel, open Power or Power Options, then click the Hibernate tab.
Also, check the Power Schemes tab. Make sure the Hibernate timeouts for both AC
power and battery power are not set to Never.
•
For Windows 98, check the Hibernate timeout in BIOS Setup—see “To run the BIOS
Setup utility” on page 131.
If your computer has more than 512 MB of RAM, you must expand the Utility
partition on the hard disk—see “To recover the factory installation of your hard disk”
on page 138.
If the Standby option is missing from the Shut Down window
•
Do not allow Windows 98 to disable APM. It may prompt you to do this in certain
situations—always answer “No”.
•
If the Windows 98 Standby option is missing, restore it as follows:
1. In Control Panel, double-click System.
2. On the System Manager tab, expand the System Devices, select Advanced Power
Management, and click Remove.
3. Restart the computer.
4. In Control Panel, double-click Add New Hardware, and follow the prompts to
install support for APM.
5. Restart the computer.
