Troubleshooting and Maintenance Troubleshooting Your Computer • Test and recondition the battery every 3 months or so using HP Battery Optimizer- see "To get the most from your batteries" on page 56. If the Time Remaining for the battery is not correct • The Time Remaining is an estimate, not a precise value, and is based on the rate at which the computer 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 runs out. So, if you check the Time Remaining while the computer 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 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 • Make sure hibernate support is enabled. From Control Panel, open Power Options, and 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. Printing Problems Hint You will usually be able to solve most printing problems by using the Print troubleshooter in Windows Help: click Start, Help and Support (or Help). If a serial or parallel printer doesn't print • Make sure the printer is on and has paper in it. • Make sure you are using the correct printer cable or cable adapter, and that the cable is secure at both ends. • Check for printer errors.
