2490 WM5 Recent overnight battery drain ...

Hey guys,
I have recently been having an issue with my 2490 battery draining overnight.
I did do the 'fake' server fix but that didn't work.

here are the programmes installed:
All up to date:
Wisbar Advance 3.1
SPB Diary
SPB Backup
SPB Traveler (weather and currency auto-updates disabled)
PocketPlus
Coreplayer
MSDict
SoftTick Card Export
Kaspersky Mobile Anti-Virus (not running in real-time and auto update disabled)
Resco Photoviewer Pro.
Resco Explorer 2007
Pocket Earth
and some games

Could any one please help with this issue. I added the programme list just incase one of them is the
culprit.

Thank you,
Paul
