No BIOS on Sony VAIO Laptop

[casaanna]

I wanted to turn my old Sony laptop into a dos machine. I got a bootable dos disc from a friend. Booted the laptop with the dos disc. It said it needed to format the hard drive. It did so and was installing dos when it prompted me to insert Disc 2 into the drive. (My friend made this disc from a set of floppies which apparently didn't work). It would not allow me to continue so i had to abort the install. Long story short, when I tried to reboot the laptop, the screen remained completely black. No cursor, no VAIO logo...nothing. I think I may have formatted the BIOS. Even if I put in my recovery disc, I get nothing. I thought BIOS was always on a separate chip...but perhaps not. Any ideas as to how to fix this?

No, only when u UPDATE your BIOS could u actually format it. Did u press DEL button when power on? And what's the model of this laptop 'cause I has an old SONY laptop wit me (technically not completely mine) too

 

[casaanna]

I tried booting with del, F1, F2, F3...nothing....nothing at all. Model # PCG GRT100

Man, yours are even newer than mine. Mine is a PCG FX-220 version.

Usually by pressing F2 it will show the bios settings.

Did u remove the battery and just plug it to the AC Adapter?

 

[casaanna]

Yes, I removed the battery. I get nothing....not a cursor.....nothing. It's like there's no bios at all. Weird.

Even nothing like the VAIO splash when power on?

Did u take your floppy out?

 

[casaanna]

nothing....and there is no floppy only a cd/dvd drive

nothing....and there is no floppy only a cd/dvd drive

What kind of the DOS Disc u have? And why it said it needed to format the HDD? Does your laptop have a OS before installation?

 

[casaanna]

Yes, it was running xp originally. I wanted to change it into a dos setup. It doesnt matter what I use now....even my recovery discs.....nothing.

 

[Maxime506]

OK, do it all over again. Do u see the HDD LED light/indicator flashing? Do u see the screen flash sth instead of completely dark? Contact your friend and make sure if the laptop wascompletely OK or problems like this one occurred?

 

[casaanna]

I've had the laptop for years....never a problem with it. It worked everytime perfectly until I tried to install dos. It formatted the drive, which I think perhaps had a hidden partition on it that included the BIOS. Now I get nothing. I don't see the HDD LED light flashing...the CD drive light flashes when a bootable disc is in it....but nothing else happens. It would be a fairly big coincidence to me, but perhaps I had a motherboard failure just as I was loading dos. I dunno....

Does your laptop has a VGA port? Try plug it to a monitor/TV, I think probably the screen go dead at that moment.
