Hello everyone! Please forgive me if this is not the appropriate forum in this forum for this type of issue: Update the Toshiba Notebook Satellite S55-A5188 Bios If it is not the appropriate Room of this Forum, please indicate to me where I should post this my great doubt. I have a S55-A5188 Satellite Notebook and it is with the latest bios update installed which was made available by Toshiba, version 1.90 according to the Aida64 data below: DMI DMI BIOS Vendor: TOSHIBA DMI BIOS Version: 1.90 DMI System Manufacturer: TOSHIBA DMI System Product: Satellite S55-A DMI System Version: PSKK2U-04M04W DMI System Serial Number: 3E171255S DMI System UUID: 10DD5E1E-C4B4E381-39012025-647FA46D DMI Motherboard Manufacturer: TOSHIBA DMI Motherboard Product: VG10S DMI Motherboard Version: To be filled by O.E.M. DMI Motherboard Serial Number: BSN12345678901234567 DMI Chassis Manufacturer: TOSHIBA DMI Chassis Version: To Be Filled By O.E.M. DMI Chassis Serial Number: CSN12345678901234567 DMI Chassis Asset Tag: No Asset Tag DMI Chassis Type: Notebook It turns out that I saw on the Internet a new update of Bios for my Satellite Notebook S55-A5188, whose version is 2.1. I downloaded the TSP55A5312.bin and TSP 55A5312.bin uncompressed files from the file spc-l-toshiba - satelites55a5188-vgsmbrev2.rar Searching the Internet, I was informed that to do this bios update would be necessary to disassemble my notebook, desoldering the chip, recording (through a bios recorder purchased separately) and resolding the chip. Is this process so complex in this way? Will I have to buy a separate bios recorder, take an electronics course, or even take an Electronic Engineering course here at a Brazilian university to become an electronics expert so I can do this update on my Satellite S55-A5188 Notebook? I count on your collaboration in my doubt! Thank you!
