Short summary and practical next steps for situation: a Sony VAIO (SZ 670 n) stopped showing anything after a BIOS flash. A blank screen and no POST usually mean the system firmware failed to initialize the CPU/board — not simply a bad setting. Confirm basic signs first: do fans spin, do any LEDs light or blink, is there HDD/SSD activity or POST beeps, and does an external monitor show anything? If there are no signs of POST, the problem is likely corrupted firmware rather than a loose cable or normal CMOS setting.

Quick, non-destructive checks to try now:

  • Power down, remove AC and main battery, press and hold power 30–60 seconds to discharge. Reconnect and test.
  • Reseat RAM and the disk drive; try an external monitor to rule out panel-only failure.
  • Removing the CMOS battery resets CMOS settings but will NOT restore a corrupted BIOS image; it only clears configuration data (so s suggestion helps only for CMOS misconfigurations, not a bad flash).

Recovery options in order of invasiveness:

  • Look for an official Sony VAIO BIOS recovery method and the exact recovery file for SZ 670 n on Sony support. Many vendors supply a crisis/USB recovery procedure that will reflash a bad image if supported.
  • If no official recovery exists, board-level reprogramming of the SPI/NOR flash is the common fix: identify the BIOS chip, use an SPI programmer (CH341A or similar) and a SOIC clip to read/backup and then write a correct ROM. This requires the exact ROM image for the board and some soldering or clip skills; a mistaken image or incorrect voltage can make things worse.
  • If not comfortable with hardware flashing, contact Sony-authorized service or an electronics repair shop that offers BIOS reprogramming or BIOS-chip replacement.

As and note, a failed flash is serious but not necessarily fatal; professional SPI reflash or chip replacement usually restores a bricked laptop. Take ESD precautions, confirm the exact board/BIOS version before flashing, and avoid using non-matching ROM files.

Flashing the bios is the most dangerous upgrade you can do to your computer ,it maybe that you ruined the bios chip and will have to have a new on installed .the bios info is what boots the computer so incorrect info is only fixed with a new bios chip with the proper info in it .so to the laptop maker you go!.

buy a new laptop.

You should never flash a BIOS unless it has a fix you really need.

Try Removing the CMOS battery and installing it after 1/2 hr .I think it should Work

you think!! if the bios was flashed and something bad happened during the flash ,the default Bios is gone! removing the battery will do nothing

once BIOS was INTERRUPTED during upgrade you screwed. yogess77 your statement will only be of good help if masoud is wrong about BIOS.witch he clearly states that it was BIOS interruption
