About this board

This thread is for the Toshiba Satellite C850 (PLF/PLR/CSF/CSR UMA).

Compare the board number printed on the PCB (near the RAM slots or under the battery) with the files before you flash. Board revision: 2.1. Match the revision as well as the board number.

From the title: integrated (UMA) graphics.

Files usually needed for this board
  • BIOS (full SPI chip dump, .bin)
  • EC / KBC firmware, if the board uses a separate EC chip
  • Schematic (PDF)
  • Boardview (.brd / .bdv / .cad)

Usually needed when the laptop powers on with a black screen after a BIOS update, is stuck in a boot loop, or is locked with a BIOS password.

Back up the original dump first — it contains machine-specific data (serial, UUID, MAC, ME), and you will want it if anything goes wrong.

If you have a working file for this board, please share it below. More files: search Toshiba Satellite C850 (PLF/PLR/CSF/CSR UMA) in File Finder.
