I have a Dell Latitude CPi in a docking station operated through a multiple keyboard/mouse switch on my home network. Last night the system froze. I tried to reboot, but I only got a beeping sound for a few seconds then silence then some more beeping then power off. I pulled the unit from the docking station and tried to boot as a normal laptop. The lock lights flashed on and off while the system beeped, stopped beeping and blinking for a second then resumed blinking and beeping then powered off. I pulled the hard drive out stuck it into another lattitude and it works fine. I have tried to boot without the battery but with the cd drive, boot with the batery and a floppy with a setup disk, boot without anything including the ethernet card. I have even tried booting with an external mouse and keyboard. It hasn't rattled about, so I don't think anything has come loose. It has been in the docking station for a long time.
