Short summary and diagnosis plan that complements the replies below.

Start by finding what actually woke the PC — that narrows everything down. Windows logs wake events in the System log (look for Power‑Troubleshooter / Event ID 1) so you can tell whether the wake came from a device, a timer/task, the network, or an ACPI/RTC alarm. (learn.microsoft.com)

What to do once you know the wake source:

  • Device wakes (mouse, keyboard, USB hubs): remove or test USB devices and change the device power settings so the hardware cannot wake the PC; update the device drivers if they’re misbehaving. (sony.com)
  • Network wakes (realtek / NICs): Wake‑on‑LAN or pattern/ARP traffic can wake machines; configure the adapter to only wake on an explicit magic packet or disable the wake permission if you don’t need remote wake. (learn.microsoft.com)
  • Timer wakes / scheduled tasks: check Task Scheduler for any tasks set to “wake the computer” (Update, maintenance, backups) and clear that option if undesired. (support.microsoft.com)
  • ACPI / RTC wake (often shown as “ACPI Wake Alarm”): some systems wake when the OS tries to move from Sleep to Hibernate or because firmware RTC alarms are enabled; changing the “hibernate after” value or disabling RTC alarms in BIOS/UEFI often fixes repeat wakes. (thewindowsclub.com)

Quick isolation checklist (fast tests): unplug USB peripherals, disconnect the network or disable Wi‑Fi, temporarily disable scheduled maintenance/update wakeups, and update chipset/BIOS drivers — test each change one at a time. Note: don’t turn off Wake‑on‑LAN if you rely on remote wake. If Event Viewer and the built‑in diagnostics don’t point to a culprit, try updating OEM chipset/ACPI drivers (this is a common fix for Vista/7 OEM builds, as observed).

What exactly is the OS you're using? 7 or vista

Anyway Here's something I found from the Windows FAQ

A program or scheduled task might be waking your computer. By default, Power Option settings do not allow scheduled tasks to wake the computer from sleep or hibernate. However, some programs might awaken the computer if these settings have been changed.

To prevent programs from waking your computer

1. Open Power Options by clicking the Start button , clicking Control Panel, clicking System and Security, and then clicking Power Options.

2. On the Select a power plan page, click Change plan settings for the plan that you want to change.

3. On the Change settings for the plan page, click Change advanced power settings.

4. On the Advanced settings tab, expand Sleep, expand Allow wake timers, choose Disable for both when your computer is running on battery and when it's plugged in, and then click OK.

I have this phenomenon on Vista HP, but the SLEEP tab doesn't have "Allow Wake Timers". It has

Sleep After
Allow Hybrid Sleep
Hibernate after

Maybe there's a registry entry someone knows about that can be altered in HP.

Found a little command that works for Windows Vista and Windows 7. Click on start and then RUN and type in cmd or just open a command prompt and type in:

powercfg –devicequery wake_armed

after this happens and it should list what woke the system. There are other powercfg commands you can use as well.

Is it possible that vibrations (i.e. from working at the desk) are jiggling the mouse.
