correctly pointed to ACPI/BIOS as the usual culprit. A few targeted checks and safe fixes follow to narrow the problem and get standby/hibernate working on Windows XP Home SP1.

Open Device Manager (My Computer > Properties > Hardware > Device Manager) and look at the Computers node. If it shows "ACPI Uniprocessor PC" or "ACPI Multiprocessor PC", Windows is using ACPI. If it shows "Standard PC", the OS was installed without ACPI support and enabling ACPI in the BIOS alone will not enable sleep/hibernate. In that case the common remedies are enabling ACPI in BIOS first, then doing a repair install of Windows (so the correct HAL is chosen) or, for advanced users, updating the "Computer" driver to an ACPI HAL — back up and have recovery media ready before trying that.

Check Control Panel > Power Options > Hibernate tab. The option will stay unavailable if the system/boot volume is compressed or lacks free space roughly equal to physical RAM (hiberfil.sys must be created). Also install the motherboard/chipset drivers and any vendor power-management utilities (especially on laptops). A BIOS update can also restore proper S1/S3 sleep-state behavior on older boards.

Look for driver or device blocks: Device Manager entries with errors, or devices whose Power Management tab is preventing sleep (network adapters, USB hubs). Event Viewer (System log) often records ACPI or power-management errors that point to a specific driver. Finally, because this setup is SP1-era, updating to the latest service pack and chipset drivers can resolve compatibility problems that prevent standby/hibernate from appearing.

How old is your computer? For standby and hibernate to work, your mobo musp support ACPI.
If your machine is ACPI compliant, the settins might be disabled in the BIOS. Go to 'Advanced Power Management' in your BIOS and enable 'ACPI compliant OS' setting. Now try enabling standby and hibenate.
If this doesn't help and the BIOS is ACPI compliant, you may need to reload the motherboard drivers. These would have come on a CD with your motherboard.
