Just got a new Sony Vaio SZ660NC through the door and had it running, all's ok. Sony update works it's magic - all ok.

Reboot, and NOTHING. Power will come on, bluetooth and power light come on but that's about it. HDD and DVD spin up but no further activity.

I was thinking perhaps the Sony Update screwed the bios?

If so - anything I can do?

Thanks!

A few practical notes that build on what suggested and that will be useful now or for anyone reading this later.

If the machine still has warranty, do not open it. Ask the repair shop to attempt non-destructive recovery steps first (vendor emergency-recovery, firmware reflash from service tools, and imaging the drive) and to document what they try before replacing the motherboard. If out of warranty, the usual house-cleaning sequence that often fixes firmware/post problems includes power-drain (remove AC and main battery, hold power for 20-30 seconds), a CMOS/RTC battery reset, reseating or testing RAM sticks one at a time, and booting with HDD/optical removed to isolate faults. Some Vaio models also include a vendor "rescue" button/mode that can trigger BIOS recovery from USB or recovery media; that is worth trying with the exact Sony image for the model.

If those do not work, technicians commonly reprogram the BIOS EEPROM with a hardware programmer or replace the EEPROM/chip rather than swap the whole board. That is cheaper and preserves data. Always request an image or return of the hard drive before any destructive repair. Ask the shop which specific recovery steps they performed (safe reflash, EEPROM programming, EC/power-rail checks) and for an itemised quote before full motherboard replacement.

bring it back to the service center if it is still under warranty perhaps the bios is corrupted already, try doing the update again check if it can work, if doesn't then maybe you screwed the bios, the worst thing is maybe got other chips affected on the mobo

Unfortunately I had to send it back to the service center - great!

Nevermind; hopefully it'll come back ok :)
