    I seem to have bricked my laptop.

    In a bad situation here where I had switched to a custom BIOS (A14_5730_840), and wanted to go back to my previous BIOS (A12) due to graphics stability issues.

    In my hurry, I selected the backup (.BAK) file as the new BIOS to flash (to return to my previous BIOS), rather than choosing the .WPH file which I usually do.

    The BIOS flashing process proceeded as normal, and the OS attempted to restart the PC after flashing was complete. At this point, all the hardware controls froze (on the restarting screen), including the power button. I had to pull the battery to get it to shut down.

    Since that time, there is absolutely no response when I attempt to power on the computer. The only perceivable activity is when I plug in AC power, the battery/power led rings on the side flicker orange momentarily.

    Is it still possible to do a crisis recovery BIOS flash somehow? I've read of reports of bricked 1645s, but usually, pressing the power button has elicited some response like the touch buttons flashing. I've tried the End+AC power/Fn+B and AC power methods to elicit a response too, with no luck. The only perceivable response is a tiny flicker from the ring LEDs whenever AC power or the battery is plugged in or removed.

    While I haven't managed to create a crisis disk so far (I have the files, but have yet to find a 32-bit computer to create the disk), I'm wondering if it's even a possibility that will work, considering there is absolutely no response?

    Anyone here faced a similar crisis? Do I need a new motherboard?
