Sony Vaio VPCSE29FJ Not Turned On After Bios Flash

[kodox]

first problem was this laptop turned on and had display on the screen, but less then a minute (while loading windows) it "auto shutdown", first i think it's a power button or circuitry around it but it's all normal after checking it thoroughly.

then i check thermal related signal (even i only had schematic from this forum) and i didn't found abnormally, it goes low after the system shutdown not before the system shutdown.

last attempt, i've uploaded the bios dump here https://www.badcaps.net/forum/showthread.php?t=85473 after flashed it to chip (with some issues) it's not turned on anymore.

anyone had clue where to look...?

revert it back to the original bios.. do you save it before you flash a new bios dump

this is an old laptop do you happen to check the bios battery? sometimes when the bios battery voltage is in the 1volt to 2 volts range it makes a weird symptoms ... just try it.

in reflashing use the board that came with your flasher and solder the eeprom there dont use a connector clip type for easy connection it is the worst thing you can do in reflashing your bios

thank's for answer, but i've tried all of your suggestion before and i've never been flashing a bios chip using a clip, i always remove the chip from the board and programmed it outside the board (off the board)

because lack of reference, i gave up on this...
thank's...
