Opened up laptop en replaced cmos battery.

I found the solution. I will post it up here so when other people ever run in to this error it can help them.

I have written the bios image on flash drive and then used command: windows key + B.

That way it worked to rewrite bios. No more problems. Restarted 10 times and everything is working fine.

I have the same problem but nothing works. Power button on wifi light (amber color) on and caps blinking twice. I have tried everything but replace the mother board. What else can be done to get the restore disks to load up.
