I have a Dell Latitude D430 laptop that I use when out and about as it is small and has integrated HSDPA. It works absolutely perfectly, but has one annoying issue that has bugged the hell out of me since I’ve had it. It won’t warm reboot. It shuts down fine, it powers on fine but if I trigger a restart from within Windows, it gets to the point where it’s meant to power cycle and hangs. It shuts everything down – Wi-Fi, Bluetooth, screen, hard drive but not the board itself. I need to hold the power button down to force it to power off and then turn it back on again. This is what I’ve already tried:-

• I have set BIOS defaults and tried every power management setting in the BIOS, same result.
• I have flashed and tested every BIOS revision for this model, all have the same result.
• I have installed all versions of Windows (XP to 8.1, 32 bit and 64 bit), all have the same result.
• I have tried Ubuntu from a live CD and installed Ubuntu, same result.
• I have swapped RAM just in case it had issues when flushing RAM on a reboot, same result.
• I have swapped the Bluetooth module, Wi-Fi module, hard drive and removed the HSDPA card, same result.
• I have swapped the battery, CMOS battery and PSU – same result.
 
IFAIK this is driver related. if a driver/service etc wont shut down nicely the system cant shut down either.

I swear there used to be a utility that told you which one it was but a quick Goggle returned nothing. I'm sure though someone will pop up with it soon.
 
Thanks for the reply, the system will shut down OK though, just not reboot from within Windows.
