Fujitsu lifebook T4220 turns on but black screen with lock flash

When I start up my lifebook it powers up but the screen remains black. When you look at the display where the battery is there is a flashing lock.
I have shut down the computer. Taken out the battery. Left the computer off for hours without the battery. Restarted the computer and the same thing happens. This has happened once before but resolved itself immediately.
The computer was shut down while it was loading prior the last time it was started and worked correctly.

Just had this problem myself. Go into your BIOS. make sure AHCI is disabled and Virtualization Technology is enabled. Then restart. This fixed it for me. Hope it does it for you.

My fujitsu t4220 will not power up


try a universal charger/power cord to see if that is the problem.
if not you can always return it.

only other option is the battery.
this has been the case with a laptop I used to have. turned out vista was the real problem though. (LOL... Crying...I HATE vista)
