My computer turns itself on when it is in my backpack. It used to do this only every once in a while (happened once the first year I owned it), then it started happening more frequently (once or twice a week) and now it happens every time I put it in my backpack.
It seems to turn on when I lift the pack, or lay it down, or otherwise cause the laptop to move position.
I already checked the BIOS to see if wake timers was turned on, but it isn't. None of the other troubleshooting tips I've found on the board have worked either...
Anyone else experiencing this? Or know what may be causing it?

I usually put it to sleep by closing the laptop cover. I have tried also manually hibernating the computer and letting it completely hibernate before closing the lid, but it still turns back on in my bag.
You are right that something may be loose. Usually what happens is I hear the computer beep in my bag, then I open it up and see that it is on so I open it and it is on the login screen. I just close it again and it turns back off. But sometimes I will take the computer out of my bag and it will not be asleep it will just be OFF. When I turn it on again the battery isn't dead, but it goes to the 'PC did not shutdown properly' screen and asks if I want to boot in safe mode.
Weird, right? But it's getting worse and worse so i really want to fix it!

"Auto-start up" caused by a physical damage is well known at the old R40 or T40-43 caused by flexing of the southbridge.
Annother reason for turning on while moving sometimes is the keyboard if it has a damage f.ex a few months after contact with liquids. If the keyboard had contact to liquids in the past, try to stop the symptom by replacing the keyboard.
If your computer will be carried daily at the same time i recommend to check the task scheduler. A couple of planed tasks can be allowed to turn on the computer to run these tasks. One of these f.ex. is the mediacenter to update the tv-guide.
Please also check the eventmanager (Control Panel - Administrative Tools - Event manager - Windows E vents - System resp. Application) for event entries at wak up time. Clicking an event will show details in the window below (double-click in XP).

I just had the keyboard replaced about 5 months ago so I'm going to assume its not a hardware issue.
In checking the event manager, I can see all the times I put my computer to sleep, and identify when it starts up on its own. I see an event before the computer starts on its own that just says "The Windows Image Acquisition (WIA) service entered the running state." This seems sto appear before an auto-start-up almost every time.
Here is an example of the list of system events at a time I know it happened yesterday:
All at 3:54:
The system is entering sleep.
The TCP/IP NetBIOS Helper service was successfully sent a stop control.
The TCP/IP NetBIOS Helper service entered the stopped state.
(two minutes later - when it auto-started)
All at 3:56:
The system time has changed to 2011-09-19T19:56:58.500000000Z from 2011-09-19T19:54:58.603639100Z.
The Windows Error Reporting Service service entered the stopped state.
Windows cannot store Bluetooth authentication codes (link keys) on the local adapter. Bluetooth keyboards might not work in the system BIOS during startup.
The Windows Image Acquisition (WIA) service entered the running state.
The system has resumed from sleep.
The TCP/IP NetBIOS Helper service entered the running state.
The Application Experience service entered the running state.
(13 minutes later, when I got somewhere I could sit down and try to turn off my computer again, and it had apparently crashed or something because there are no events after this and when I turned on the computer again I got the 'windows is recovering from an unexpected shutdown, start in safe mode?' boot screen)
All at 4:10:
The operating system started at system time 2011-09-19T20:10:02.375199700Z.
File System Filter 'FileInfo' (6.1, 2009-07-13T19:21:51.000000000Z) has successfully loaded and registered with Filter Manager.
The previous system shutdown at 4:01:02 PM on 9/19/2011 was unexpected.
Microsoft (R) Windows (R) 6.01. 7601 Service Pack 1 Multiprocessor Free.
The Event log service was started.
The system uptime is 26 seconds.
The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.
Then a bunch more startup stuff, upon which I closed the lid again (still at 4:10) and the system stayed off till I started again.
Any thoughts/advice are appreciated.

If enabled, then disable the "hybride suspend/hibernation" in the power manager.
This feature works together with the BIOS setting "Config" - "Power" - "Timer wake with battery operation" - please set it on "disabled".
See this article to understand the background.

Thanks for all the responses.
"Allow hybrid sleep" is OFF and "Allow Wake Timers" is set to disable.
Currently when I close the lid the computer is supposed to go to sleep. I am trying to see if it will stay off if I change it to hibernate when I close the lid.
Ultimately I may have to go to the service desk, but even though my laptop is still under warranty I have NO expectation that getting the computer serviced will even be possible.
