My laptop is TravelMate P645-S-51VV. Bios version is V1.11.S01. Operation system is Microsoft Windows 10 1709.
I try to update to the last BIOS version from acer support site: 1.19 (file name - A4DBH119.exe) and received an error - "model name compare error!"
I also tried bios version 1.20 from here https://br.answers.acer.com/app/answers/detail/a_id/53114/~/vulnerabilidades-de-segurança-meltdown-e-spectre#_ga=2.13336819.558135042.1541623450-532894673.1541623450 but i got the same error.
