each time i power on the laptop the fan spins and the keyboard light comes up then after few seconds it goes back off...I'm guessing it could be the bios file please can anyone help me with a clean file...Thanks

SMDFlea hoaca388 Ive tried me clean, but to be honest Im still a newby and all tries ended up failing.
Note : This is when I take an identical laptop bios, then i can get it booting , but it still takes very long and the service tag/mac/express serive tag is then incorrect in the bios.
The other laptop bios attached that post but is slow, my service tag is above at 226

Try

hi all good member

I need someone do me a favour to know what is difference between this two bios bin instead of model and serial number. one of them is for dell 7390 and another 7490.
my problem is with Microsoft account, when I am programming bios bin file from 7390 on 7490 laptop work without Microsoft account but when I programming 7490 bios bin then there is Microsoft account on it and I can't find what is difference.
thanks in advance

I have a Dell 7490 laptop but it only has lighting on the keyboard and no image. I already cleaned the bios but it does the same thing to me. I don't know if anyone can keep an eye on it.I do not have service tag since the tag was deleted

I believe my BIOS is kind of corrupt, 1 out of 20 tries it boots
