    I have a HP Pavilion dv4t-1000 CTO Entertainment Notebook PC and after updating my bios from F.22 to F.24 the computer wont boot into Vista. It was completed successfully using the winflash, but the computer restarted it just stays at a black screen, and wont go any further :eek: . (I hope bios is not corrupted :eek: .)

    The computer is on but its not booting the operating system.

    Is there any way I can revert to the old bios :confused: ??

    Also is there any key combination that can get it to load BIOS from a USB flash drive??

    Please can someone help, I have some work to finish up but then this happened :mad:

    Chances are that the BIOS are corrupted, which means the laptop is a brick in need of repair. There is no way to recover from bad BIOS, since BIOS have to work to even communicate with USB ports and whatnot.

    However, one idea comes to mind. Take out the battery and unplug the laptop, and hold the power button for 60 seconds. Plug in and try to boot, does that help? Sometimes static electricity builds up in the laptop and causes odd things to happen.

    It seems as if the bios is loaded because all the lights are on and I can press ctrl-alt-delete and it seems as if the computer restarts... so I guess it can register key input that's for sure.

    Ill try what you said Greg and post an update. Thanks for the quick reply btw.

    THANKS A LOT scnsc for the link to 0.0 s post (I'll give you some reps for the post). I used it recovered my bios to the latest IT WORKED. I will write a guide for the dv4t soon when I have time....but just in case there is somebody with the same problem, here's something I learned, In the latest bios F.24 there are two .FD files:

    30F7F24 D.FD - THIS IS BIOS FOR DV4T WITH DEDICATED NVIDIA GRAPHICS CARD
    30F7F24 U.FD - THIS IS FOR THE DV4T WITH INTEL UMA

    Change this to 30F7.BIN
