I have a Dell Vostro 1000 laptop that will no longer power on after a BIOS update. The BIOS flash process seemed to go just fine, but after shutting down I'm not able to turn it on anymore, at all--no illuminated LEDs (not even momentarily), no spinning fans, no sounds, apparently nothing at all. The latest official BIOS is here: downloads.dell.com/bios/WinVost263.EXE I believe it's a regular Phoenix BIOS since it comes with WinPhlash. I've tried as many of the Phoenix and Dell recovery methods that I've seen posted around here as I could find--removing the battery and power cord, and then holding various key combinations while plugging the power cord back in (Win+B, Fn+B, End, Ctrl+F, Ctrl+W, Ctrl+End, Ctrl+Home are the ones I tried, and then tried holding the power button along with each, and then tried not holding power but pressing it after plugging in the cord while still holding the other keys). No sign of anything happening ever with any of those attempts, not even a red battery LED or anything. Anyone know if I could be missing something here? Maybe a different key combination? Or if there's something else I can try other than buying a new motherboard or desoldering the BIOS chip to flash it externally (I'm a bit terrible at soldering anything other than through-hole stuff)? Is it possible to do a JTAG flash on this model (I would consider trying that if all else fails)? Thanks for any help. I've been looking around quite a bit for a solution on my own the last few days but I'm still stuck.
