Re: BIOS upgrades - reflashing the BIOS
i purchased an ACER notebook, model 5420, and there is a known problem of
Black Screen that appears during use which freezes the computer. apparently,
the solution is to "flash the bios". i have never done anything like this
before. is this a process i can do without terminal consequences? i have
downloaded a zip drive that supposedly contains the fix for this problem. can
someone refer me to a link or instruction of how to flash the bios and how to
apply the information in the zip drive? much appreciated. i am using vista.
