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.

Tried the European ACER FTP site and the main, I find no files or
information for the 5420.

There is a 5220, 5520, 6520, 5720, 5920, 6920, 7220, and up, and no 5420.

I do, however, find a number of suggestions [forums discussing the 5420]
that the panam site may have one, though that requires FLASH, so you will
have to try that site for your self.

AS for the zip drive, do you actually mean a zip file, if so unzip with a
zip file tool, or within VISTA. Check the file for viruses first, and LOOK
at the supposed file before using it. MAKE sure it is ACTUALLY for your
motherboard/notebook or you WILL have a new hunk of plastic and parts.

Not necessarily for systems which use an IN Bios flash tool..Make sure you
get the proper flash tool for the specific need/chip
