Windows XP: no standby mode possible

Windows XP responds to faulty drivers

Such errors often happen after changes to the system or new installations of Windows XP. The causes are usually complex and require patience. Windows XP usually installs all needed driver automatically. In many cases, however, a driver also needs to be updated.

• Check whether the driver for the "Standby" energy saving function is actually available. To do this, go to "Start / Settings / Control Panel / System / Hardware / Device Manager / System Devices / ACPI Switches.

• If you can see a yellow triangle there, this driver must be installed later. Try this with: Mark the ACPI switch and then delete it. After the restart, Windows XP retrofits the driver again.

• Start your BIOS - this differs depending on the type, often with the "F2" key and check whether the "enabled" button is set for the "Energy management" feature.

• Right click on the desktop, select Properties / Screen Saver / Power Management / Advanced / Hibernate. Set the appropriate checkmarks.

The power management can cause "no standby"

• Find the "Power Management" setting in the Control Panel and see whether the "Hibernate / Standby" functions are activated. After the change, restart your PC.

• If none of this is successful, you should clean the registry with a cleaning program. Entries that are no longer valid can hinder or switch off current functions.

• Inserting the installation CD can also help if you select the "Repair" function in the menu. A very rare cause would be a weak BIOS battery that would have to be replaced with a new one.
