Possible Fix for Windows Mobile 2003 Reminder Issue
There's an interesting thread on Brighthand started by PATRICKJEF - he says he talked to someone at HP about the reminder issue and this was their response:
"...this (the alarm situation) has been escalated to Microsoft. What is happening has to do with the "housekeeping" that occurs at midnight. The Operating System comes on for 15 seconds at or around midnight , as you know, to perform housekeeping duties. Within those responsibilities is the packing of the alarm database file, dbnotify. Unfortunately, 15 seconds is not long enough for all of this to happen. On top of this, every time a soft reset is performed, the size of the Dbnotify file, doubles. Hence, the 15 seconds grows shorter and shorter as there is more to do and less time to get it done. This time will be increased in the following release to 1 minute."
This description might indeed be accurate - as of yet I haven't heard of any truly definitive description of the problem. The thread goes on to provide a download that apparently fixes the problem - but also seems to cause a few other issues. Be very careful installing software from unknown sources.

Don't they need to get the dbnotify doubling error fixed as well?
It's pretty bad that such a huge bug got passed Microsoft into the final release of WM2003. That dbnotify bug isn't pretty, and enough soft-resets can slow a WM2003 device down to a crawl.

Hello! Why not make it so that it doesn't HAVE to do any housekeeping at midnight??
I wish it didn't turn on at all at midnight. If you have Media Player running, but on Pause while in suspend mode... the Pocket PC will power on at midnight, and will never shut off since Media Player is presumed active. Well... it'll shut off when the battery is dead.

I've got to go along with RK here. If it's not a bug, what's the purpose behind the doubling the Dbnotify store? Microsoft, why don't you address that issue before simply extending the "midnight ON time" from 15 seconds to 1 minute?

As a reasonably regular soft-resetter, I'm interested to know whether the dbnotify file grows indefinitely, or there is some way of getting it back under control (apart from a hard reset)?

I believe what helps, is to change a certain registry key that defines the shut off time after the device wakes up for housekeeping. I changed this key (and am still evaluating if it fixes the alarm-issue, since i've just done it a few days ago):
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Power And change the following key: DWord value WakeupPowerOff set to 60 (decimal, or: 0x3C hexadecimal).
Needless to say that you gotta be carefull if you start messin' with the registry. For the DBNotify pile-up, i use the scarybear utility. Of course that's no fix, but just a 'plug-to-close-the-hole' 
Me too is baffled by how on earth a huge software company like M$ could have let a major flaw in the OS slip through onto the market like this... :? Don't they test and debug their stuff at all then ? :|
Apart from these bugs i gotta say that i hardly ever reset my new h4150, maybe once in a week or so... So stability has defenitely improved so far...

ScaryBear Fix
I installed two programs from ScaryBear that seem to resolve this issue. One works with each soft reset, the other is a standalone program. Here's the link: http://www.scarybearsoftware.com/ppc_cn_overview.html
Thoughts?

I still don't even know how to get reliable, repeating
alarms on my PPC 2002 iPaq 3660 
My iPaq is a great tool, but the most important
part (reminders/alarms) is defective
Anyone with any ideas on how to 'fix' my ipaq
en get alarms working properly. ?
Ivan
P.S. mods : if this is OT, please split the thread and
move my post to the appropriate forum.

Well this fits exactly with my experience.
I have tried probably all the tweaks around, including the scary bear tweak, with no success UNTIL
I tried the freeware Wake Up tweak from burr oak (available here :http://www.burroak.on.ca/wm2k3tweaks.html).
Since starting to use a couple of weeks ago I gone from getting no alarms at all (if the device was off) to getting alarm it set. The Ipaq finally makes it into my morning alarm routine something I haven't done since my PPC2K 3660.
The wakup tweak basically sets the Wakeup Idle timeout to 60seconds (though user configurable) rather than the 15 seconds default. So this fits totally with the first posting.
It really has fixed my one huge problem with my 5550.
