issue with dell latitude 5480 bios rewrite

Re: issue with dell latitude 5480 bios rewrite

i believe i've identified and corrected an issue with my programmer. i have since reprogrammed a T460S with a couple reads/writes, all successful.

i am now able to consistently read/write to this dell

i have tried five different dumps though, and they all spin the fans and shut down

anybody?

Re: issue with dell latitude 5480 bios rewrite

all of my other dumps will power on the laptop with black screen and fan spin.

this bios does not respond to power button \-;

i took this BIOS and ran MEinject on it, and it does light up the power LED and spin the fans now

also i notice that the LCD is turning on... no backlight, but LCD gets darker, before it cuts off

i tried writing the other EC, but the laptop won't even spin fans with that EC written. i'll try this one after work today.

thanks!

Re: issue with dell latitude 5480 bios rewrite

ok, i couldn't wait until after work. i wrote the bios and the EC, and these results:

connect power, power LED comes on
no response to power button
LCD comes on (no backlight)
after some time, fan spin
fans/lights off
power LED back on, but no activity

post..the original bios of the laptop,

I have no way to confirm the BIOS installed there... About the motherboard I guess should be the LA-E081P.
