HP 370697-002 manual If the Time Remaining for the Battery Pack Is Not Correct

Page 80

Troubleshooting

■If the operating time has gradually become shorter and the battery pack is more than a year or two old, you may need to replace the battery pack.

■Heavy modem use can impact battery-operating time.

■PC Card use can impact battery-operating time.

■Test and recondition the battery pack every 3 months.

If the Time Remaining for the Battery Pack Is Not Correct

The Time Remaining is an estimate, not a precise value, and is based on the rate at which the notebook is using power at the moment. This value therefore depends on your current task and assumes that you will continue using power at the same rate until the battery pack runs out. So, if you check the Time Remaining while the notebook is performing a task requiring a good deal of power (such as reading from a CD or DVD), the value will probably show less time remaining than you really have, since you will probably later switch to tasks that require less power.

If the Notebook Does Not Enter Standby Mode as Expected

■If you have a connection to another computer, the notebook will not enter Standby if the connection is active.

■If the notebook is performing an operation, it normally waits for the operation to finish before going into Standby.

If the Notebook Does Not Enter Hibernation as Expected

■Make sure Hibernation support is enabled. From Control Panel, open Power Options, then select the Hibernate tab.

■Check the Power Schemes tab. Make sure the Hibernation timeouts for both AC power and battery power are not set to Never.
